Constitutional Foundations of Criminal Responsibility and the Principle of Fault

Roadmap: Why Does Fault Matter in Criminal Practice?

This article proceeds in three movements. The principal reading (Part 3) explains the organizing concepts of actus reus and mens rea, the vocabulary of fault, the distinction between subjective and objective standards, the presumption of subjective fault as a matter of statutory interpretation, and then the constitutional overlay: what section 7 requires, why “stigma” became the operative concept, and where the Court drew the lines. The case analysis (Part 5) works through the four principal authorities in detail, together with the supporting decisions you need to read them properly (Re B.C. Motor Vehicle Act, DeSousa, Logan, Beatty, Roy). Part 6 then brings you up to date on what has changed since 2017: the relocation of the driving offences into Part VIII.1 of the Criminal Code in December 2018; the repeal of s. 230 and the amendment of s. 229(c) in 2019; Javanmardi (2019) on manslaughter and criminal negligence; Chung (2020) on momentary conduct and the marked-departure standard; Zora (2020) on the presumption of subjective fault; Goforth (2022) on the objective standard for necessaries-of-life and criminal negligence; and the Brown (2022) decision that struck down the 1995 version of s. 33.1 on fault and voluntariness grounds, followed within weeks by Parliament’s replacement provision.

Why this matters for practice: every element analysis you will ever do begins with the question “what fault does this offence require, and is that fault subjective or objective?” A theft under $5,000 file turns on a subjective “fraudulently and without colour of right” inquiry; an assault file turns on an “intentional” application of force; a dangerous driving file turns on an objective “marked departure”. Being able to say immediately which standard governs, and why Parliament was constitutionally permitted to choose it, is the foundation for bail submissions, Crown negotiations, voir dires on statements (where the accused’s state of mind is often the only live issue), and jury-charge appeals.

3. Mens Rea in Canada: A Complete Substantive Explanation of Fault

3.1 Why is fault the organizing idea of criminal responsibility?

The criminal law is the state’s most coercive instrument. It authorizes stigmatizing public condemnation, loss of liberty, and lasting collateral consequences. Every mature legal system therefore confronts the same question: on what basis may the state justly impose that condemnation on an individual? The answer that the common law developed, and that the Charter has partially constitutionalized, is that criminal punishment presupposes personal fault. A person is punished not simply because a harmful event occurred, but because the person is morally responsible for it: the harm is attributable to a choice, or at least to a culpable failure to attend to a risk that a reasonable person would have attended to.

Two Latin tags have carried that idea for centuries. Actus non facit reum nisi mens sit rea — an act does not make a person guilty unless the mind is also guilty — captures the proposition that a prohibited act (the actus reus) must be accompanied by a culpable mental state (the mens rea). The tags are useful, but they are also misleading if taken literally. “Guilty mind” suggests wickedness or evil motive; Canadian law requires nothing of the kind. Motive is generally irrelevant to liability (though relevant to proof and to sentence). What the law demands is a defined state of mind, or a defined failure to meet a standard of care, in relation to each of the external elements of the particular offence. The “mind” that must be “guilty” is a technical construct, and the precise construct differs from offence to offence.

It helps to see fault as the hinge between two different accounts of what criminal law is for. On a retributive or desert-based account, punishment is justified only as a response to blameworthy wrongdoing, and the degree of punishment should track the degree of blame; fault is therefore foundational. On a consequentialist (deterrence, incapacitation, rehabilitation) account, fault matters because only a person who could have chosen otherwise can be deterred, and because punishing the faultless produces fear without benefit. Both accounts converge on the conclusion that a fault requirement is essential; they diverge on how much fault is required and on whether society may ever punish on an objective basis (what a reasonable person would have realized) rather than a subjective basis (what this accused actually realized). That divergence is the single most important theoretical fault-line in this article, and in Canadian criminal law generally.

3.2 Actus reus and mens rea as analytical tools

The actus reus of an offence is the sum of its external elements. Those elements can be grouped into three types. First, conduct: an act (applying force; taking property; operating a conveyance) or, where a legal duty exists, an omission. Second, circumstances: facts that must exist for the conduct to be criminal (the force was applied without consent; the property belonged to someone else; the complainant was under sixteen). Third, consequences: results that the conduct must bring about (bodily harm; death). Not every offence has every type of element. Assault under s. 265(1)(a) is complete on conduct and circumstance (intentional application of force, without consent); murder requires a consequence (death) and the causal link between conduct and consequence. Embedded within the conduct element is the requirement of voluntariness: the act must be the product of the accused’s conscious will, a matter examined in detail in the next article in this series and again in later articles on automatism and intoxication, where you will see that R. v. Brown, 2022 SCC 18 treats voluntariness as an independent principle of fundamental justice.

The mens rea of an offence is the mental element, or the fault element, that must attach to the actus reus. The crucial analytical move, and the one that separates competent from superficial analysis, is to ask what fault attaches to each element of the actus reus. Canadian law does not have a single mens rea for an offence; it has a fault requirement for the conduct, a fault requirement for each circumstance, and (where there is one) a fault requirement for the consequence, and these need not be the same. Assault illustrates this. The conduct element (applying force) requires intention. The circumstance element (absence of consent) requires knowledge, recklessness or wilful blindness, because s. 265(4) allows an honest-belief-in-consent defence and the Crown must disprove it where there is an air of reality. Unlawful act manslaughter illustrates the opposite extreme: the consequence element (death) requires no subjective fault at all, only objective foreseeability of bodily harm.

A second analytical move is to distinguish the elements of the offence, which the Crown must prove beyond a reasonable doubt, from defences, which may operate as denials of an element (mistake of fact negates the mens rea for a circumstance; automatism negates voluntariness) or as justifications and excuses that concede the elements but deny criminal responsibility (self-defence, duress, necessity). For the purposes of this article, the most important point is that the burden of proving every element, including fault, rests on the Crown throughout; the accused bears at most an evidential burden to put a defence in play (an “air of reality”). The constitutional dimension of that allocation is s. 11(d) of the Charter, which, together with s. 7, was the basis of the decisions in Vaillancourt and Martineau.

A third move is to understand that the words “actus reus” and “mens rea” are not themselves found in the Criminal Code. Parliament drafts offences using words such as “wilfully”, “knowingly”, “intentionally”, “fraudulently”, “with intent to”, “recklessly”, “negligently”, or sometimes no fault word at all. The courts then interpret those words, and the silences, using common-law presumptions, and since 1982 they test the result against the Charter. The relationship between statutory text and common-law doctrine is therefore layered: text first, then interpretive presumption, then constitutional minimum. Keeping those three layers separate is the key to reading the leading cases correctly, because Creighton, for example, is a decision about layer three (what s. 7 minimally requires) and not about layer two (what the best interpretation of s. 222(5)(a) would otherwise be).

3.3 The vocabulary of fault

Intention (or “intent”) in Canadian law has two forms. A person intends a consequence if the person acts in order to bring it about (direct intention, sometimes called purpose), or if the person acts knowing that the consequence is virtually certain to follow even though it is not the person’s purpose (oblique or indirect intention). The Ontario Court of Appeal’s decision in R. v. Buzzanga and Durocher (1979), 49 C.C.C. (2d) 369 remains the standard Canadian statement: “wilfully” promoting hatred captures both the person whose conscious purpose is to promote hatred and the person who foresees that promotion of hatred is certain or substantially certain to result from the act. Intention is distinct from motive: the reason for which a person forms an intention. A person who kills a terminally ill spouse to end suffering has the intention to kill; the compassionate motive is irrelevant to the mens rea of murder, though it may inform sentence (the Latimer litigation is the standard illustration).

Knowledge is the fault element that attaches to circumstances. One cannot “intend” that property belongs to another; one can know that it does. Knowledge in the criminal law means actual awareness or true belief that the circumstance exists. Where an offence requires knowledge, an honest mistake of fact, even an unreasonable one, negates fault, unless Parliament has expressly required that the belief be reasonable or has imposed a “reasonable steps” obligation (as in ss. 150.1(4) and 273.2 for sexual offences, where the analysis is different and will be taken up later in this series).

Recklessness was defined by McIntyre J. in Sansregret v. The Queen, [1985] 1 S.C.R. 570 as the attitude of one who, aware that there is danger that the prohibited conduct could bring about the result prohibited by the criminal law, nevertheless persists despite the risk. Two features matter. Recklessness is subjective: the accused must actually have adverted to the risk. And it is a lesser form of fault than intention: the reckless person does not want or foresee the result as certain; the person foresees it as possible and proceeds anyway. Where Parliament uses “intentionally” or “means to” without more, recklessness is generally not enough (murder under s. 229(a)(i), for example, requires that the accused “means to cause death”), but where the statute is silent, the presumption discussed in 3.4 makes recklessness a sufficient form of subjective fault for most offences.

Wilful blindness is not a form of recklessness; it is a substitute for knowledge. It arises where a person who has become aware of the need for inquiry deliberately declines to make it because the person does not want to know the truth. Sansregret established the concept; R. v. Briscoe, 2010 SCC 13 restated it as “deliberate ignorance” and insisted that the test is whether the accused’s suspicion was aroused to the point where the accused saw the need for further inquiries but deliberately chose not to make them. The doctrine is important because it closes a loophole: an accused who would otherwise escape a knowledge-based offence by carefully avoiding confirmation of what is strongly suspected is treated as if the accused knew. Its danger, discussed in Part 8, is that triers of fact collapse it into “ought to have inquired”, which is negligence, not wilful blindness.

Negligence, in the criminal sense, is a failure to live up to a standard of care that a reasonable person would have met, in circumstances where the risk was objectively foreseeable. It is objective because it does not depend on what the accused actually perceived. Canadian law, however, distinguishes civil negligence (any falling short of the standard) from penal negligence, which requires a “marked departure” from the standard of the reasonable person (Hundal; Creighton; Beatty). Criminal negligence as defined in s. 219 of the Criminal Code (“wanton or reckless disregard for the lives or safety of other persons”) requires a still higher degree: a “marked and substantial” departure (R. v. J.F., 2008 SCC 60; Javanmardi). Note the trap in s. 219’s wording: although the section uses the word “reckless”, the Supreme Court has settled that the standard is objective, not subjective recklessness in the Sansregret sense. The Court divided evenly on that question in R. v. Tutton, [1989] 1 S.C.R. 1392; the objective reading prevailed in later cases.

3.4 Subjective versus objective fault, and the presumption of subjective fault

A subjective fault standard asks what was actually in the accused’s mind: did this person intend, know, foresee or consciously disregard the relevant risk? An objective standard asks what a reasonable person in the accused’s position would have perceived or done, and treats the accused’s failure to perceive or act accordingly as culpable. The subjective standard reflects the liberal premise that blame requires choice. The objective standard reflects the competing premise that a person who undertakes an activity (driving, caring for a child, handling a firearm) assumes a social responsibility to meet the minimum standard of care that activity demands, and that failure to do so is itself a culpable choice, or at least a culpable inattention, even if the risk never crossed the person’s mind.

Canadian law uses both standards, and the first question in any element analysis is which one Parliament chose. Where the text is clear — “knowingly”, “with intent to”, “means to”, “wilfully” on the subjective side; “negligently”, “reasonable care”, “dangerous to the public” on the objective side — the text governs, subject to the Charter. Where the text is silent, the common law supplies a presumption of subjective fault: in the absence of a clear legislative indication to the contrary, a true crime is presumed to require subjective mens rea in relation to its elements, and recklessness suffices unless the offence specifies a higher form. The presumption has deep roots (Beaver v. The Queen, [1957] S.C.R. 531; R. v. Sault Ste. Marie, [1978] 2 S.C.R. 1299) and the Supreme Court reaffirmed it emphatically in R. v. A.D.H., 2013 SCC 28 (child abandonment under s. 218, held to require subjective fault) and again in R. v. Zora, 2020 SCC 14 (breach of a release condition, held to require subjective fault). The presumption is an interpretive rule, not a constitutional one: Parliament may displace it by clear language, and in A.D.H. itself Moldaver J. (concurring) would have read s. 218 as objective. The presumption’s practical significance is enormous because the majority of Criminal Code offences specify no fault word at all.

Three further points round out the picture. First, the division into subjective and objective is not exhaustive. Sault Ste. Marie recognized three categories of offence: true crimes (subjective fault presumed); strict liability offences (the Crown proves the actus reus; the accused may avoid liability by proving due diligence on a balance of probabilities); and absolute liability offences (no fault at all). The strict-liability category is the default for regulatory or “public welfare” offences and will be the subject of its own article; it is mentioned here because the constitutional cases discussed next began with the absolute-liability category. Second, objective standards in Canadian criminal law are never bare civil negligence: the “marked departure” gloss is itself part of what makes them constitutionally acceptable. Third, the distinction between “general intent” and “specific intent” offences (R. v. Tatton, 2015 SCC 33) is a different axis altogether. It concerns the complexity of the mental element for the purpose of the intoxication rules, not whether the standard is subjective or objective; it will be treated in the article on intoxication and should not be confused with the categories discussed here.

3.5 Section 7 of the Charter and the constitutional floor of fault

Section 7 provides that everyone has the right to life, liberty and security of the person and the right not to be deprived thereof except in accordance with the principles of fundamental justice. A criminal conviction carrying the possibility of imprisonment engages the liberty interest; the question is therefore whether the fault structure of the offence accords with the principles of fundamental justice. The decision that opened this door was Reference re Section 94(2) of the Motor Vehicle Act (B.C.), [1985] 2 S.C.R. 486. Lamer J. held that the principles of fundamental justice are substantive, not merely procedural, and that it is a principle of fundamental justice that a person may not be imprisoned for an absolute liability offence, because imprisoning the morally innocent (one who could not have known of, or avoided, the prohibited circumstance) offends the basic tenets of our legal system. The constitutional floor was thus first set at the bottom of the Sault Ste. Marie ladder: absolute liability plus possible imprisonment is unconstitutional. R. v. Hess; R. v. Nguyen, [1990] 2 S.C.R. 906 applied the principle to strike the former “statutory rape” offence, which made the accused’s belief about the complainant’s age irrelevant.

The next question was whether s. 7 says anything about the kind of fault, as opposed to its mere existence. The answer, developed through Vaillancourt (1987), Martineau (1990), Logan (1990), DeSousa (1992), Hundal (1993) and Creighton (1993), can be stated as a set of propositions, each of which is examined in the case analysis in Part 5.

First, for a small number of offences, the stigma attaching to conviction and the severity of the available punishment are so great that the principles of fundamental justice require subjective fault in relation to the prohibited consequence. Murder is the paradigm: Vaillancourt held that objective foreseeability of death was the constitutional minimum for murder and struck the “constructive murder” rule in the former s. 213(d); Martineau went further and held that subjective foresight of death is required, striking s. 213(a). Attempted murder (Logan) and war crimes and crimes against humanity (R. v. Finta, [1994] 1 S.C.R. 701) have been treated similarly. Theft, which carries a stigma of dishonesty, was mentioned in Vaillancourt as a candidate, but the point was never decided and has had no practical significance because s. 322 already requires subjective fault.

Second, for all other true crimes, s. 7 does not require subjective fault. Parliament may legitimately choose an objective standard. Hundal upheld an objective standard for dangerous driving; Creighton upheld an objective standard for unlawful act manslaughter, and its companion cases upheld objective standards for careless use of a firearm (R. v. Gosset, [1993] 3 S.C.R. 76) and failure to provide the necessaries of life (R. v. Naglik, [1993] 3 S.C.R. 122).

Third, where an objective standard is used for a true crime, the constitution requires that it be a standard of penal, not civil, negligence: the conduct must amount to a marked departure from the standard of the reasonable person. This proposition is most clearly stated in Creighton and in the Beatty line of driving cases, and it was applied in Brown (2022) to explain why Parliament’s replacement s. 33.1 would be constitutional if it required a marked departure in relation to the consumption of intoxicants.

Fourth, there is no constitutional requirement of symmetry between the actus reus and the mens rea: Parliament may attach liability for a consequence (bodily harm, death) to an accused who subjectively intended only the underlying conduct, provided the consequence was objectively foreseeable (DeSousa; Creighton). The “thin-skull” principle in the law of causation operates on the same logic. Symmetry remains a value in statutory interpretation and in criminal theory, but it is not a principle of fundamental justice.

Fifth, s. 7 is engaged not only by the absence of fault but by substitution: a provision that allows the Crown to prove some other fact in place of the essential fault element violates s. 11(d) (the presumption of innocence) unless proof of the substituted fact leads inexorably to the existence of the essential element (Vaillancourt). That was the second ground on which the constructive murder provisions fell, and it was the principal reason the 1995 version of s. 33.1 fell in Brown: the intention to become intoxicated was being substituted for the fault element of the violent offence.

3.6 Stigma, punishment and the “special” offences

It is important to see how unusual the Canadian approach is. Most constitutional systems leave the definition of fault to the legislature. The Supreme Court of Canada instead identified a constitutional minimum keyed to two variables: the social stigma attaching to the label of the offence, and the severity of the penalty. The logic in Martineau is that the label “murderer” carries a unique moral condemnation and the sentence is a mandatory life term, and that it would be contrary to fundamental justice to apply that label and that sentence to a person who did not subjectively foresee the death. The principle of proportionality between moral blameworthiness and punishment is thereby elevated to a principle of fundamental justice, at least in its extreme applications.

The weakness of the stigma criterion is that it is impressionistic and circular. Stigma is partly a product of the label the law itself attaches; the Court is in effect saying that because the law treats murder as uniquely serious, the law must treat murder as uniquely serious. Why manslaughter (a homicide offence, with a maximum of life imprisonment) carries insufficient stigma to require subjective fault, whereas attempted murder (where no one dies) carries sufficient stigma, is a question the cases answer by assertion rather than argument. Scholarly reaction, canvassed in Part 8, has ranged from Don Stuart’s long-standing argument that stigma is an unworkable criterion and that subjective fault should be the general constitutional rule, to the view associated with Kent Roach and others that the Court’s minimalism was prudent because it left Parliament room to use objective standards for regulatory-type harms such as driving. What is settled is the doctrinal outcome: the “special stigma” category is closed in practice to murder, attempted murder and war crimes, and the Court has shown no inclination since 1994 to expand it.

One consequence deserves emphasis for a practitioner who studied before 2017. The constructive murder provisions struck in Vaillancourt and Martineau (the former s. 213, renumbered s. 230) remained in the printed Criminal Code for almost thirty years after they became inoperative, as did the “ought to know” words in s. 229(c) that Martineau had rendered inoperative. Parliament finally repealed s. 230 and amended s. 229(c) by S.C. 2019, c. 25 (Bill C-75), in force in 2019. The legal position has not changed, but the printed text has.

3.7 Penal negligence: the “marked departure” standard and the modified objective test

Where the fault standard is objective, two questions arise: how far below the standard of care must the accused’s conduct fall, and whose characteristics define the reasonable person? Canadian law answers the first with the “marked departure” requirement and the second with the “modified objective test”, and these two phrases are routinely confused.

The marked departure requirement, articulated in Hundal, confirmed in Creighton and made the centrepiece of R. v. Beatty, 2008 SCC 5 and R. v. Roy, 2012 SCC 26, is a requirement of degree. Civil negligence (a momentary lapse, a simple error of judgment) is not enough. The trier of fact must be satisfied that the conduct fell so far short of the reasonable standard that it merits criminal condemnation. In Beatty, a driver whose vehicle crossed the centre line for a few seconds, killing three people, was acquitted because the lapse, though catastrophic in consequence, was momentary and unexplained; it was not a marked departure. Roy emphasized that the trier must not reason backwards from the gravity of the consequences to the existence of fault, and that the inquiry focuses on the manner of driving, not the result. For criminal negligence under s. 219, the required degree is higher still: a marked and substantial departure.

The modified objective test, articulated in Hundal and refined in Creighton and Beatty, concerns the perspective from which the standard is applied. It is objective in that it asks what a reasonable person would have foreseen and done; it is “modified” in that the reasonable person is placed in the accused’s circumstances, including the circumstances the accused actually confronted and, importantly, any honest and reasonable mistake of fact the accused laboured under. In Hundal, Cory J. described it as allowing the accused to raise a reasonable doubt by showing that a reasonable person in the accused’s position would not have been aware of the risk. What the modification does not include, on the majority view in Creighton, is the accused’s personal characteristics: inexperience, lack of education, youth, low intelligence or impulsivity do not lower the standard. The only exception is incapacity: an accused who lacked the capacity to appreciate the risk inherent in the conduct is not held to a standard the accused could not meet. McLachlin J.’s rationale was that a uniform standard is essential to the protective function of the law and to equality before the law; Lamer C.J.’s minority view, that the standard should be personalized for “human frailties” short of incapacity, has never commanded a majority but remains the standard foil in academic debate. Javanmardi (2019) added an important refinement from the other direction: although the standard is not lowered for personal deficits, it is informed by the activity, so that a person undertaking an activity demanding special skill (administering intravenous injections) is measured against the reasonable person undertaking that activity.

The structure of the inquiry, as settled by Beatty and Roy for dangerous driving and applied by analogy to other objective-fault offences, is as follows. The actus reus is established by asking whether, viewed objectively and in light of all the circumstances, the conduct was dangerous (for driving, “dangerous to the public”). The mens rea is established by asking whether the degree of care exercised by the accused was a marked departure from the standard of care that a reasonable person would have observed in the accused’s circumstances. Although the accused’s actual state of mind is not an element, evidence of it is relevant: proof that the accused was subjectively aware of the risk and ran it deliberately will almost always establish a marked departure, and evidence of a sudden and unforeseeable medical event, or of a reasonable mistake of fact, may negate it. Chung (2020) added that the momentariness of the conduct is not a legal barrier; a brief but extreme act (accelerating to nearly three times the speed limit approaching an intersection) can itself be a marked departure.

3.8 Symmetry, predicate offences and consequence-based crimes

Several important offences are built on a predicate: unlawful act manslaughter (s. 222(5)(a)), unlawfully causing bodily harm (s. 269), assault causing bodily harm (s. 267(b)), aggravated assault (s. 268) and the aggravated forms of the driving offences. In each, the accused must have the mens rea for the underlying act, and liability for the aggravated consequence is imposed without proof that the accused intended or foresaw that consequence. DeSousa settled the structure for s. 269 and Creighton for manslaughter: the underlying act must be a federal or provincial offence that is not itself an offence of absolute liability, and the consequence must have been objectively foreseeable. For manslaughter, the consequence that must be foreseeable is bodily harm that is neither trivial nor transitory, not death. For s. 269, it is bodily harm. The Javanmardi majority clarified in 2019 that “objective dangerousness” of the unlawful act is not a free-standing element of the actus reus; it is simply the objective-foreseeability-of-bodily-harm fault requirement expressed differently. The point matters for jury charges and for the kind of evidence that will be relevant.

The theoretical objection to these structures is that they violate the correspondence (or symmetry) principle: the mens rea should mirror every element of the actus reus. The Supreme Court’s answer is that symmetry is a value, not a constitutional rule, and that the moral difference between a person who commits a dangerous assault that happens to kill and one who commits the same assault without that result is a matter of moral luck for which the law may legitimately hold the actor responsible, provided the risk of some harm was objectively foreseeable. Lamer C.J.’s minority view in Creighton, that fundamental justice requires foreseeability of the very consequence (death), would have narrowed manslaughter substantially; it did not prevail.

3.9 Applications: assault, theft, dangerous driving, manslaughter, murder

Assault (s. 265). The actus reus is the application of force to another person, directly or indirectly, without consent. The mens rea for the conduct element is intention: s. 265(1)(a) uses the word “intentionally”, so an accidental or reflexive contact is not an assault, and recklessness as to whether force is applied is not enough. The mens rea for the circumstance element (absence of consent) is subjective: knowledge, recklessness or wilful blindness; an honest belief in consent, even an unreasonable one, is a defence to simple assault, though the trier may consider the presence or absence of reasonable grounds in deciding whether the belief was honestly held (s. 265(4)). Common assault cases therefore involve a wholly subjective fault structure, and the constitutional cases have no direct application to them; where they do become relevant is the moment an assault is charged as assault causing bodily harm or aggravated assault, because the consequence element is then governed by the DeSousa objective-foreseeability rule. Note also that for assault under s. 265(1)(a) the Crown need not prove that the accused intended to injure; intention to apply force suffices, which is why an unwanted shove is an assault.

Theft (s. 322). The section is drafted with layered subjective fault: the taking or conversion must be “fraudulently and without colour of right” and must be accompanied by one of the enumerated intents (to deprive the owner temporarily or absolutely, to pledge, and so on). “Fraudulently” imports a subjective element of dishonesty; “colour of right” refers to an honest belief in a legal (not merely moral) entitlement, and because it is a matter of the accused’s actual belief, an honest but mistaken belief in a legal right is a complete answer even if unreasonable. Theft is thus the clearest example of an offence whose text leaves no room for an objective standard, and it is the reason the Vaillancourt obiter about theft carrying a special stigma has never had to be tested. For theft under $5,000 (s. 334(b)), your element analysis should always separate the taking, the “fraudulently” element, the “without colour of right” element, and the specific intent, because mistake-of-fact and colour-of-right arguments attach to different elements.

Dangerous driving (now “dangerous operation” of a conveyance, s. 320.13). This is the archetypal objective-fault true crime. The actus reus is operating a conveyance in a manner that, having regard to all the circumstances, is dangerous to the public. The mens rea is a marked departure from the standard of care of a reasonable person in the accused’s circumstances (Hundal; Beatty; Roy; Chung). Where bodily harm or death results (s. 320.13(2) and (3)), the consequence must be caused by the dangerous operation but no additional fault in relation to the consequence is required. The offence was formerly s. 249; Part VIII.1 of the Code, enacted by S.C. 2018, c. 21 and in force 18 December 2018, replaced it. The jurisprudence under s. 249 continues to apply.

Manslaughter (ss. 222(5), 234, 236). Culpable homicide that is not murder is manslaughter. The two principal routes are unlawful act manslaughter and criminal negligence manslaughter. For unlawful act manslaughter, the Crown proves the underlying offence with its own mens rea, causation of death, and objective foreseeability of the risk of non-trivial bodily harm (Creighton; Javanmardi). For criminal negligence manslaughter, the Crown proves conduct showing wanton or reckless disregard for life or safety (s. 219), measured as a marked and substantial departure, and causation. The maximum penalty is life imprisonment, with a four-year minimum where a firearm is used (s. 236(a)), which makes the modesty of the fault requirement a persistent subject of criticism.

Murder (s. 229). Since Martineau, every route to murder requires subjective foresight of death. Section 229(a)(i) requires that the accused meant to cause death; s. 229(a)(ii) requires that the accused meant to cause bodily harm that the accused knew was likely to cause death, and was reckless whether death ensued; s. 229(b) applies those states of mind to a transferred-intent situation; and s. 229(c) applies where the accused, for an unlawful object, does anything the accused knows is likely to cause death. The “ought to know” alternative in s. 229(c) was inoperative after Martineau and was removed in 2019. The classification into first- and second-degree murder (s. 231) is a sentencing classification that applies after murder is proven and adds no further fault element except where the classification itself turns on intent (planned and deliberate murder under s. 231(2)).

3.10 Commonly confused doctrines

Two short hypotheticals consolidate the material. First: A shoves B at a bar; B stumbles, strikes a table, and suffers a fractured wrist. A intended the shove but neither intended nor foresaw injury. A is guilty of assault (intentional application of force) and, because a fractured wrist is objectively foreseeable from a shove near furniture, of assault causing bodily harm; A’s lack of foresight of the injury is no defence (DeSousa). Second: C, driving at the limit, is distracted for two seconds by a crying child in the back seat, drifts across the line and causes a fatal collision. The consequence is as grave as it could be, but a two-second distraction of that kind is the sort of momentary lapse that Beatty and Roy treat as civil negligence; absent more, C is not guilty of dangerous operation causing death, and the trier must resist reasoning from the result to the fault.

4. Legislative and constitutional authorities

Currency. All Criminal Code provisions below were checked on 6 October 2026 against the Justice Laws consolidation (current to 17 March 2026, last amended 10 October 2025). Quotations are limited to the words needed for teaching; read the full provisions in the Practitioner’s Criminal Code 2026 or at laws-lois.justice.gc.ca/eng/acts/C-46/. The Canada Evidence Act, the Controlled Drugs and Substances Act (beyond its role as a predicate offence in Creighton), the Youth Criminal Justice Act and the Extradition Act do not bear directly on the doctrine discussed here and are not treated here.

4.1 Canadian Charter of Rights and Freedoms, ss. 1, 7 and 11(d)

s. 7. “Everyone has the right to life, liberty and security of the person and the right not to be deprived thereof except in accordance with the principles of fundamental justice.”

s. 11(d). Any person charged with an offence has the right “to be presumed innocent until proven guilty according to law in a fair and public hearing by an independent and impartial tribunal”.

What they govern and how they are read. Section 7 is engaged whenever a conviction can lead to imprisonment, because imprisonment deprives the accused of liberty. The analysis then asks whether the law’s fault structure accords with a “principle of fundamental justice”, a phrase that Re B.C. Motor Vehicle Act held to include substantive principles found in the basic tenets of the legal system. Four such principles are in play today: that the morally innocent not be punished (no absolute liability with imprisonment); that the fault element be proportionate to the stigma and penalty of the offence (subjective foresight for murder); that penal negligence require a marked departure; and that voluntariness is a prerequisite of criminal liability (Brown). Section 11(d) adds the independent rule against substituted proof of an essential element: where the Crown is permitted to prove fact X instead of essential element Y, the presumption of innocence is infringed unless proof of X leads inexorably to Y. A violation of s. 7 is in principle justifiable under s. 1, but the Court has repeatedly said that it will be rare for a s. 7 violation in the criminal-fault context to be saved; in Vaillancourt, Martineau and Brown the s. 1 argument failed. Why it matters: any challenge to an offence’s fault element is pleaded under ss. 7 and 11(d), with a s. 24(1) or s. 52(1) remedy, and a defence Charter notice in a provincial court must identify which principle is relied on.

4.2 Criminal Code, s. 229 (murder) and the repealed s. 230

s. 229. “Culpable homicide is murder (a) where the person who causes the death of a human being (i) means to cause his death, or (ii) means to cause him bodily harm that he knows is likely to cause his death, and is reckless whether death ensues or not; (b) where a person, meaning to cause death to a human being or meaning to cause him bodily harm that he knows is likely to cause his death, and being reckless whether death ensues or not, by accident or mistake causes death to another human being, notwithstanding that he does not mean to cause death or bodily harm to that human being; or (c) if a person, for an unlawful object, does anything that they know is likely to cause death, and by doing so causes the death of a human being, even if they desire to effect their object without causing death or bodily harm to any human being.” [Amended by S.C. 2019, c. 25, s. 77.]

s. 230. Repealed, S.C. 2019, c. 25, s. 78.

Components and interpretation. Each limb of s. 229 now requires subjective foresight of death. Section 229(a)(ii) is the limb most often litigated in practice: the accused need not want death, but must mean to cause bodily harm and must know that the harm is likely (not merely possible) to cause death; the recklessness clause adds nothing in practice, because one who knows death is likely and proceeds is necessarily reckless. Section 229(c) was historically the most troubling, because it imposed liability for a death the accused knew (or, in the former text, “ought to have known”) was likely, in the course of pursuing a different unlawful object. Martineau rendered the objective words inoperative; R. v. Shand, 2011 ONCA 5 is the leading appellate restatement of the elements of s. 229(c) as it now operates, and the 2019 amendment conformed the text to Martineau. Section 230 (the former s. 213) imposed “constructive” or “felony” murder liability for deaths caused during listed offences; Vaillancourt struck para. (d) and Martineau struck para. (a), with the balance of the section widely treated as inoperative, until its repeal. Interaction: s. 231 classifies murder as first or second degree for sentencing (s. 745); s. 21(2) party liability for murder is read with Logan; s. 232 (provocation) reduces murder to manslaughter. Why it matters: in every homicide file the first strategic question is whether the Crown can prove the s. 229 state of mind, and the structure of that question is the direct product of the s. 7 jurisprudence discussed in this article.

4.3 Criminal Code, ss. 219–222, 234 and 236 (criminal negligence; culpable homicide; manslaughter)

s. 219(1). “Every one is criminally negligent who (a) in doing anything, or (b) in omitting to do anything that it is his duty to do, shows wanton or reckless disregard for the lives or safety of other persons.” Subsection (2) defines “duty” as a duty imposed by law.

s. 222(5). “A person commits culpable homicide when he causes the death of a human being, (a) by means of an unlawful act; (b) by criminal negligence; (c) by causing that human being, by threats or fear of violence or by deception, to do anything that causes his death; or (d) by wilfully frightening that human being, in the case of a child or sick person.”

s. 234. “Culpable homicide that is not murder or infanticide is manslaughter.” s. 236 provides the penalty (life; four-year minimum with a firearm).

Components and interpretation. Section 219 defines a form of fault rather than an offence; the offences are ss. 220 (causing death) and 221 (causing bodily harm) and the manslaughter route in s. 222(5)(b). Despite the words “wanton or reckless”, the standard is objective and requires a marked and substantial departure (J.F.; Javanmardi; Goforth). Section 222(5)(a) is interpreted in accordance with Creighton: an unlawful act (not absolute liability), objectively foreseeable risk of non-trivial bodily harm, causation of death. The “unlawful act” may be a provincial offence or a federal offence outside the Code; in Creighton it was trafficking under the Narcotic Control Act, the predecessor of s. 5 of the Controlled Drugs and Substances Act, because “administering” a drug is within the definition of trafficking. Why it matters: the choice between charging manslaughter by unlawful act and by criminal negligence changes the required degree of departure and the jury charge.

4.4 Criminal Code, Part VIII.1, s. 320.13 (dangerous operation)

s. 320.13(1). “Everyone commits an offence who operates a conveyance in a manner that, having regard to all of the circumstances, is dangerous to the public.” Subsections (2) and (3) add “and, as a result, causes bodily harm to another person” and “the death of another person”. Punishment: ss. 320.19 (simple), 320.20 (bodily harm), 320.21 (death: life). [Enacted by S.C. 2018, c. 21, s. 15; in force 18 December 2018.]

Components and interpretation. The provision replaced s. 249 with no change in substance to the elements, and the Hundal–Beatty–Roy–Chung line continues to govern. “Conveyance” (s. 320.11) covers motor vehicles, vessels, aircraft and railway equipment. The former s. 249’s language (“having regard to all the circumstances, including the nature, condition and use of the place … and the amount of traffic”) was simplified, but the courts continue to consider those circumstances. Why it matters: any pre-2018 case citing s. 249 must be read as applying to s. 320.13, and counsel must cite the current section in informations and Charter notices.

4.5 Criminal Code, s. 265 (assault) and ss. 322, 334 (theft)

s. 265(1)(a). A person commits an assault when “without the consent of another person, he applies force intentionally to that other person, directly or indirectly”. s. 265(4) allows the trier, where the accused alleges an honest belief in consent, to consider the presence or absence of reasonable grounds for that belief in determining its honesty.

s. 322(1). “Every one commits theft who fraudulently and without colour of right takes, or fraudulently and without colour of right converts to his use or to the use of another person, anything, whether animate or inanimate, with intent (a) to deprive, temporarily or absolutely, the owner of it … of the thing …”. s. 334(b) provides the penalty where the value does not exceed $5,000 (hybrid).

Components and interpretation. Both offences are textually subjective. For assault, “intentionally” governs the application of force; consent and belief in consent are governed by the subjective Sansregret/Briscoe framework (knowledge, recklessness, wilful blindness), and s. 265(4) is an evidentiary direction, not a reasonableness requirement (contrast s. 273.2 for sexual assault). For theft, “fraudulently” and “without colour of right” are both subjective; the leading authorities will be discussed in a later article on theft. Why it matters: these are familiar offences; recognizing that they sit entirely above the constitutional floor explains why the s. 7 cases are rarely cited in such files, and why the real fight is usually about proof of state of mind rather than its definition.

4.6 Criminal Code, s. 33.1 (self-induced extreme intoxication) — current text

s. 33.1 [S.C. 2022, c. 11, s. 1; in force 23 June 2022]. In substance: a person who, by reason of self-induced extreme intoxication, lacks the general intent or the voluntariness required to commit an offence involving an assault or other interference with the bodily integrity of another person nonetheless commits the offence if all the other elements are present and if, before becoming extremely intoxicated, the person departed markedly from the standard of care expected of a reasonable person in the circumstances with respect to the consumption of intoxicating substances. The court must consider the objective foreseeability of the risk that the consumption could cause extreme intoxication and lead the person to harm another, and all relevant circumstances including anything the person did to avoid the risk.

Why it appears in a discussion of fault. The provision is the most recent and clearest legislative application of the principles in Part 3: Parliament replaced a provision that substituted the intent to become intoxicated for the fault of the violent offence (struck in Brown) with one that locates the fault in a marked departure, assessed by objective foreseeability, in relation to the consumption itself. It is therefore an example of a constitutionally compliant objective-fault structure drafted directly in response to the s. 7 jurisprudence. A later article on intoxication will treat the defence itself.

4.7 Criminal Code, s. 21(2) (common intention) — note

Section 21(2) extends party liability to offences a co-participant “knew or ought to have known” would be a probable consequence of carrying out a common unlawful purpose. Logan held that the objective words are inoperative where the offence charged is one for which the constitution requires subjective foresight (attempted murder; by extension, murder). Parliament has not amended the text; the words remain and are simply not applied to those offences. This is a live example of a provision whose printed text does not state the operative law, and it will be revisited in a later article on parties to offences.

5. Leading case analysis

Paragraph references are given only where verified against the official judgment. For the four pre-neutral-citation cases, read the judgments in the Supreme Court Reports or on the SCC’s decisions website (links in Part 13); the headnotes are reliable, but you should read the full majority reasons in Martineau and Creighton at least once. Everything labelled “synthesis” is my analysis and should not be attributed to the court.

5.1 R. v. Vaillancourt, [1987] 2 S.C.R. 636 (SCC, 3 December 1987)

Material facts. Vaillancourt and an accomplice committed an armed robbery of a pool hall in Montreal. Vaillancourt carried a knife; the accomplice carried a gun. Vaillancourt testified that he had insisted the gun be unloaded, that the accomplice had removed the bullets in his presence, and that he had put the bullets in his own glove (where the police later found them). During the robbery the accomplice shot and killed a patron and escaped. Vaillancourt was charged with second-degree murder and convicted on the basis of the former s. 213(d) (later s. 230(d)), which deemed a culpable homicide to be murder where a person caused death while committing an enumerated offence (including robbery) and the person used or had a weapon upon the person, whether or not the person meant to cause death or knew that death was likely. The Quebec Court of Appeal affirmed.

Issue. Whether s. 213(d), by permitting a murder conviction without proof of any foresight of death, infringed ss. 7 and 11(d) of the Charter, and if so whether it was saved by s. 1.

Holding. Appeal allowed; new trial ordered. Section 213(d) infringes ss. 7 and 11(d) and is not justified under s. 1.

Ratio and reasoning. Lamer J., for the majority, reasoned from Re B.C. Motor Vehicle Act that s. 7 imposes a minimum mens rea requirement, and that for a limited number of offences the stigma and the penalty are such that the principles of fundamental justice require a mental element reflecting the particular nature of the crime. Murder, he held, is such an offence: it would be unjust to label as a murderer a person who did not at least objectively foresee death. Because s. 213(d) permitted conviction even where the accused reasonably believed that death could not result (an accused who honestly and reasonably believed the gun to be unloaded), it allowed conviction of a person who lacked even objective foreseeability; it therefore violated s. 7. Separately, it violated s. 11(d), because it substituted proof of the use of a weapon during the underlying offence for proof of the fault element of murder, and proof of the substituted fact did not lead inexorably to the existence of the essential element. Section 1 could not justify it, because the objective of deterring weapon use in the commission of offences could be achieved by less drastic means (the existing offences and the sentencing powers). Lamer J. expressly left open whether subjective foresight of death was the true minimum, stating that it was unnecessary to decide. McIntyre J. dissented, holding that Parliament was entitled to define murder as it chose and that the courts should not read into s. 7 a particular theory of mens rea.

Binding ratio versus obiter. The ratio is narrow: a murder provision that permits conviction without at least objective foreseeability of death violates s. 7 and is not saved by s. 1, and substituted proof violates s. 11(d). The suggestions that theft and other offences carry a “special stigma”, and that subjective foresight may be constitutionally required for murder, were obiter, the second of which became the ratio in Martineau.

Subsequent treatment and present importance. Vaillancourt is the source of the “stigma” criterion and of the s. 11(d) substitution rule, both still applied (the latter was central in Brown). It has not been overruled or limited. Its principal limitation is the vagueness of the stigma criterion, which has been developed only by assertion in later cases.

Synthesis. The decision is best read as a statement of methodology rather than of result: s. 7 contains a sliding scale of required fault keyed to stigma and penalty, and the Court will police the lower end of that scale. Its enduring practical significance lies in s. 11(d): any provision that deems a fault element to exist upon proof of something else is vulnerable.

5.2 R. v. Martineau, [1990] 2 S.C.R. 633 (SCC, 13 September 1990)

Material facts. Martineau, aged 15, and his companion Tremblay set out armed with a pellet pistol and a rifle, Martineau believing they were going to commit a break and enter. They broke into a trailer in Alberta and, after robbing the occupants, Tremblay shot and killed Mr. and Mrs. McLean. Martineau was convicted of second-degree murder under the former s. 213(a) (later s. 230(a)), which deemed a death to be murder where it was caused in the course of enumerated offences by a person who meant to cause bodily harm for the purpose of facilitating the offence or escape, whether or not death was foreseen. The Alberta Court of Appeal ordered a new trial, holding s. 213(a) unconstitutional; the Crown appealed.

Issue. Whether s. 213(a) infringed ss. 7 and 11(d), and, more generally, what minimum fault s. 7 requires for murder.

Holding. Crown appeal dismissed. Section 213(a) infringes ss. 7 and 11(d) and is not saved by s. 1. The principles of fundamental justice require, as a minimum for a murder conviction, proof beyond a reasonable doubt of subjective foresight of death.

Ratio and reasoning. Lamer C.J., for the majority, built on Vaillancourt and settled what that case had left open. Murder is distinguished from manslaughter only by the mental element; the stigma of the label “murderer” and the mandatory life sentence are the most severe in Canadian law; and it is therefore a principle of fundamental justice that this label and penalty be reserved for those who either intend to cause death or intend to cause bodily harm knowing it is likely to cause death. The principle that punishment be proportionate to moral blameworthiness is the foundation. Section 213(a) permitted conviction on proof of an intention to cause bodily harm for the purpose of facilitating an offence, a state of mind that does not inexorably entail foresight of death; it therefore substituted a lesser fault for the required one (s. 11(d)) and dispensed with the constitutionally required fault (s. 7). The section was not saved by s. 1 because a provision that stigmatizes and punishes as murderers persons who did not foresee death is not a proportionate means of deterring the underlying offences. Lamer C.J. added that the “ought to know” words in s. 212(c) (now s. 229(c)) were likewise inoperative, a point confirmed in later cases and ultimately by Parliament in 2019.

Concurring and dissenting reasons. Sopinka J. concurred in the result but would have decided only that s. 213(a) was unconstitutional, cautioning against laying down a general rule of subjective foresight that would foreclose Parliament. L’Heureux-Dubé J. dissented, arguing that stigma was an inadequate basis for constitutionalizing a particular theory of mens rea, that objective foreseeability of death was a sufficient constitutional minimum, and that s. 213(a) satisfied it because one who intentionally inflicts bodily harm during a serious crime can reasonably be expected to foresee death. Subsequent treatment and present importance. Martineau remains the controlling statement of the constitutional fault requirement for murder and has been applied consistently (including in Logan, extending it to attempted murder, and in the treatment of s. 229(c)). Parliament repealed s. 230 and amended s. 229(c) in 2019 to conform. The L’Heureux-Dubé dissent is the standard academic foil and is worth reading in full because its criticism of the stigma rationale has never been fully answered.

Limitations and unresolved questions. The decision does not define “stigma” or supply a test for identifying other offences in the special category; the Court has never extended the category beyond murder, attempted murder and war crimes. Whether the mandatory life sentence (rather than the label) is doing most of the work is an open theoretical question that became relevant again in the s. 12 litigation over parole ineligibility (R. v. Bissonnette, 2022 SCC 23).

5.3 R. v. Hundal, [1993] 1 S.C.R. 867 (SCC, 11 March 1993)

Material facts. Hundal was driving an overloaded dump truck in downtown Vancouver and entered an intersection on a red light that had been red for some time, striking a car that had entered lawfully on a green light and killing its driver. Witnesses said he could have stopped. He testified that he thought he could not stop safely and so honked and proceeded. He was convicted of dangerous driving causing death (then s. 233; later s. 249; now s. 320.13(3)). The British Columbia Court of Appeal upheld the conviction.

Issue. Whether the mens rea of dangerous driving is subjective or objective, and whether an objective standard is consistent with s. 7.

Holding. Appeal dismissed. The mens rea for dangerous driving is assessed objectively, on a “modified objective test”; this is consistent with s. 7.

Ratio and reasoning. Cory J., for the majority, gave four reasons for an objective standard: driving is a licensed, regulated activity which the licensee undertakes knowing its risks; it is automatic and reflexive, so that subjective inquiry into momentary states of mind is unrealistic; the statutory language (“dangerous to the public, having regard to all the circumstances”) points to an objective assessment; and the number of deaths and injuries on the roads justifies a standard that protects the public. The test is “modified” because the trier must consider the whole of the surrounding circumstances and whether a reasonable person in the accused’s situation would have been aware of the risks; an accused can raise a reasonable doubt by showing, for example, a sudden and unexpected onset of illness. The required degree of departure is a “marked departure” from the standard of the reasonable driver. McLachlin J. (as she then was), concurring, agreed with the objective standard but reasoned that the only “modification” needed was the inclusion of the circumstances, not any inquiry into the accused’s awareness; La Forest J. concurred separately. On the facts, driving an overloaded truck through a stale red light was plainly a marked departure.

Subsequent treatment and present importance. Hundal was refined by Beatty (which clarified the actus reus / mens rea division and the content of the modified objective test) and Roy, and applied in Chung. Its reasoning was carried over to the other objective-fault cases decided later in 1993 (Creighton, Gosset, Naglik). It remains good law under s. 320.13.

Synthesis. The case established that an objective standard is constitutionally permissible for an activity-based offence of ordinary stigma, and it supplied the two phrases (marked departure; modified objective test) that still structure the analysis. The debate between Cory J. and McLachlin J. about how much “modification” is permissible was resolved in Creighton in McLachlin J.’s favour on personal characteristics, while retaining Cory J.’s point that reasonable mistakes of fact and the circumstances actually confronted are relevant.

5.4 R. v. Creighton, [1993] 3 S.C.R. 3 (SCC, 9 September 1993)

Material facts. Creighton, an experienced cocaine user, injected cocaine into the arm of Kimberley Ann Martin, with her consent, in the presence of a friend, Caddedu, over a period of consumption in Toronto. She immediately convulsed and stopped breathing. Caddedu wanted to call for help; Creighton persuaded him not to, and the two cleaned the apartment of fingerprints and left. Caddedu returned later and called 911; Martin was dead. Creighton was charged with manslaughter and convicted on the basis of unlawful act manslaughter, the unlawful act being trafficking (by administering) under the Narcotic Control Act. The Ontario Court of Appeal affirmed.

Issue. Whether the mens rea for unlawful act manslaughter, as settled in DeSousa (objective foreseeability of bodily harm), is consistent with s. 7, or whether fundamental justice requires objective foreseeability of death and, further, whether the objective standard must be personalized to the accused.

Holding. Appeal dismissed; conviction affirmed. The Court was unanimous in the result but divided five to four on the reasons.

Majority ratio (McLachlin J., with La Forest, L’Heureux-Dubé, Gonthier and Cory JJ.). The mens rea for unlawful act manslaughter is objective foreseeability of the risk of bodily harm that is neither trivial nor transitory, in the context of a dangerous act; foreseeability of death is not required. This is consistent with s. 7 for three reasons. The stigma of manslaughter is appropriately less than that of murder and the penalty is discretionary, so the fault requirement may be lower; the common law has long imposed manslaughter liability on this basis; and symmetry between the consequence (death) and the fault element is not a principle of fundamental justice, the “thin-skull” rule in causation illustrating that an accused takes the victim as found. On the standard’s content, McLachlin J. held that the reasonable person is not endowed with the accused’s personal characteristics (age, experience, education, temperament) except where the accused lacked the capacity to appreciate the risk; a uniform standard is required by the principle of equal treatment, by the protective purpose of penal negligence, and by the need to prevent the standard from dissolving into a subjective one. The departure must be “marked”.

Minority reasons (Lamer C.J., with Sopinka, Iacobucci and Major JJ.; concurring in the result). Lamer C.J. would have held that s. 7 requires objective foreseeability of death for manslaughter, reasoning that the offence carries a serious stigma and that the fault element should correspond to the consequence. He would also have personalized the objective standard, so that the reasonable person shares the accused’s “human frailties” (such as inexperience or lack of education) that would have prevented the accused from appreciating the risk, provided the frailties were not themselves the product of a culpable choice. On the facts, he concluded that Creighton, as an experienced drug user, would have foreseen the risk of death, so the conviction stood.

Subsequent treatment. The majority’s position has been applied without qualification: Beatty and Roy (driving), Javanmardi (confirming the activity-sensitivity of the standard and clarifying “objective dangerousness”), Goforth (confirming that personal characteristics short of incapacity do not lower the standard for s. 215, while the accused’s actual circumstances define the setting in which the reasonable person is placed) and Brown (relying on the “marked departure” minimum). It has not been overruled, limited or seriously questioned at the Supreme Court. The personal-characteristics holding continues to attract scholarly criticism and is the subject of Part 8.

Limitations and unresolved questions. The line between “incapacity to appreciate the risk” (relevant) and “diminished ability to appreciate the risk” (irrelevant) is unstable and has produced inconsistent lower-court treatment of cognitive disability, FASD, and youth. The majority’s reliance on the discretionary penalty is weakened by the four-year mandatory minimum later added to s. 236 for firearms manslaughter. And the extent to which the “circumstances” of the accused can be defined so as to include matters that look like personal characteristics (for example, the accused’s limited caregiving role in Goforth) remains a matter of characterization.

Practical and academic significance. Creighton is the single most important Canadian decision on objective fault. Practically, it defines the Crown’s burden in every manslaughter and penal-negligence prosecution; academically, it is the locus of the subjectivist–objectivist debate and of the equality critique of the uniform standard.

5.5 Supporting authorities (brief)

Reference re s. 94(2) of the Motor Vehicle Act (B.C.), [1985] 2 S.C.R. 486. Absolute liability combined with possible imprisonment violates s. 7; principles of fundamental justice are substantive. Foundation of all that followed.

R. v. Logan, [1990] 2 S.C.R. 731. The objective “ought to have known” branch of s. 21(2) cannot be applied to attempted murder, for which subjective intent to kill is constitutionally required (building on R. v. Ancio, [1984] 1 S.C.R. 225); the same follows for murder. Text unchanged but partly inoperative.

R. v. DeSousa, [1992] 2 S.C.R. 944. Unlawfully causing bodily harm (s. 269) requires an underlying unlawful act (not absolute liability) that is objectively dangerous in the sense that bodily harm is objectively foreseeable; no subjective foresight of the harm is required; s. 7 does not require symmetry. The structural template that Creighton adopted for manslaughter.

R. v. Beatty, 2008 SCC 5. Charron J. for the majority: the actus reus of dangerous driving is driving that is objectively dangerous; the mens rea is a marked departure, assessed on the modified objective test; a momentary lapse of attention is not a marked departure; evidence of the accused’s actual state of mind, though not an element, is relevant. Acquittal restored. McLachlin C.J. and Fish J. wrote concurring reasons differing on the structure of the analysis.

R. v. Roy, 2012 SCC 26. Cromwell J. for a unanimous Court: the trier must not infer a marked departure from the consequences; the focus is on the manner of driving; a momentary error of judgment in pulling onto a highway in poor visibility was not a marked departure. Acquittal entered.

R. v. A.D.H., 2013 SCC 28. Cromwell J. for the majority: the presumption of subjective fault applies to child abandonment (s. 218); the mother who, believing her newborn dead, left the child in a store washroom was properly acquitted. Moldaver J. (concurring in result) would have applied an objective standard. The leading modern statement of the presumption.

6. Recent developments (since 2017)

Each item below was verified on 6 October 2026. None of the four principal cases has been overruled, reversed or materially limited; the developments refine or apply them. They are presented chronologically.

6.1 Part VIII.1 of the Criminal Code (S.C. 2018, c. 21), in force 18 December 2018

Bill C-46 repealed ss. 249 to 261 and re-enacted the driving offences as ss. 320.11 to 320.4. Dangerous driving became “dangerous operation” of a “conveyance” (s. 320.13). The elements are unchanged and the Hundal line applies; the provision numbers in every pre-2019 case and textbook are now obsolete. Effect on doctrine: confirms, no change.

6.2 R. v. J.F.-line confirmation and R. v. Javanmardi, 2019 SCC 54 (14 November 2019)

Facts and history. Javanmardi, a naturopath practising in Quebec for many years, administered intravenous nutrients to an 84-year-old patient with heart disease at his request on a first visit; one vial was contaminated and he died of endotoxic shock within hours. She was acquitted at trial of criminal negligence causing death and unlawful act manslaughter (the unlawful act alleged being the practice of medicine contrary to Quebec’s Medical Act). The Quebec Court of Appeal set aside the acquittals and entered a conviction on manslaughter. The Supreme Court restored the acquittals.

Holdings. Abella J. for the majority (Moldaver, Karakatsanis, Côté and Brown JJ.) held, first, that the fault element for criminal negligence causing death is conduct amounting to a marked and substantial departure from the standard of the reasonable person in the circumstances, and that while the standard is not reduced for the accused’s personal characteristics it is informed by the activity undertaken, so that greater care may be expected of one who undertakes a skilled activity (paras. 21, 37–38 as summarized from the judgment). Second, for unlawful act manslaughter, the actus reus is satisfied by proof that the accused committed an unlawful act that caused death; there is no independent requirement of “objective dangerousness” of the unlawful act (para. 30). Dangerousness is subsumed in the fault element: objective foreseeability of the risk of bodily harm that is neither trivial nor transitory (para. 26), which is what DeSousa and Creighton had always required (para. 27). On the facts, the trial judge was entitled to find that an experienced naturopath who had administered injections for years, using what she reasonably believed were sterile materials, did not depart markedly from the standard and that the risk of non-trivial bodily harm was not objectively foreseeable in her circumstances.

Dissent. Wagner C.J. and Rowe J. would have upheld the manslaughter conviction, reasoning that injecting substances intravenously is inherently dangerous regardless of the accused’s experience.

Effect on doctrine. Javanmardi confirms Creighton, clarifies the structure of unlawful act manslaughter (removing a separate “dangerousness” step that some appellate courts had added), and complicates the uniform-standard rule by making the standard sensitive to the activity and to the accused’s experience within it. Critics (notably Lisa Silver) have argued that the activity-sensitive approach reintroduces personal characteristics through the back door; defenders say it merely identifies the correct “circumstances”. It is the most important post-2017 case for this article.

6.3 S.C. 2019, c. 25 (Bill C-75), ss. 77–78: amendment of s. 229(c) and repeal of s. 230

Parliament removed the words “or ought to know” from s. 229(c) and repealed s. 230 entirely, bringing the text of the Code into conformity with Vaillancourt and Martineau after nearly three decades. Effect on doctrine: none; effect on practice: the “zombie” provisions are gone, and jury charges on s. 229(c) should follow the amended text.

6.4 R. v. Chung, 2020 SCC 8 (20 March 2020)

Facts and history. Chung accelerated to roughly 140 km/h in a 50 km/h zone in Vancouver over about one block, approaching an intersection, and collided with a vehicle turning left, killing its driver. The trial judge acquitted of dangerous driving causing death on the footing that the excessive speed was momentary and therefore not a marked departure. The British Columbia Court of Appeal set aside the acquittal and entered a conviction; the appeal to the Supreme Court was as of right.

Holding. Martin J. for the majority dismissed the appeal: the trial judge erred in law by treating the momentary nature of the conduct as, in effect, precluding a finding of marked departure. Beatty and Roy hold that a momentary lapse of attention is usually not a marked departure; they do not hold that momentary conduct can never be one. Brief but extreme conduct — deliberate acceleration to nearly three times the limit toward an intersection — can be a marked departure, and the inquiry concerns what a reasonable person would have foreseen and done in the circumstances, not the duration of the conduct in isolation. Karakatsanis J. dissented on the ground that the trial judge’s reasons disclosed no error of law and the Crown’s complaint was really about the application of the standard to the facts, which is not appealable by the Crown from an acquittal.

Effect on doctrine. Limits an over-reading of Beatty; confirms the modified objective test. Also a useful illustration of the question-of-law / mixed-question boundary that governs Crown appeals from acquittals, to be revisited in later articles on appeals.

6.5 R. v. Zora, 2020 SCC 14 (18 June 2020)

Facts and history. Zora, released on bail in British Columbia with a curfew and a condition to present himself at the door when police attended, failed to answer the door on two occasions; he said he had been asleep in a bedroom from which he could not hear. He was convicted of failing to comply with a condition of his release (then s. 145(3)). The conviction was upheld on appeal; the Supreme Court allowed the appeal and ordered a new trial.

Holding. Martin J. for a unanimous Court held that the offence requires subjective mens rea: the Crown must prove that the accused knowingly or recklessly failed to comply with the condition. The presumption of subjective fault was not displaced by the text, and the objective of the bail system (restraint; conditions tailored to the individual) and the serious consequences of a breach conviction for liberty supported a subjective reading. The Court also used the occasion to restate the ladder principle and the requirement of restraint in imposing bail conditions.

Effect on doctrine. Confirms and strengthens the presumption of subjective fault (A.D.H.). Note that the failure-to-comply offences were reorganized by Bill C-75 later in 2019; the current provision for breach of a release order is s. 145(5), and Zora applies to it.

6.6 R. v. Brown, 2022 SCC 18 (13 May 2022) and the new s. 33.1 (S.C. 2022, c. 11, in force 23 June 2022)

Facts and history. Brown, a university student in Calgary, consumed alcohol and psilocybin mushrooms at a party, lost touch with reality, broke into a nearby home and violently attacked the occupant, who suffered lasting injuries. The trial judge found that he was in a state of extreme intoxication akin to automatism, held the 1995 version of s. 33.1 (which removed self-induced intoxication as a defence to general-intent offences involving violence) unconstitutional, and acquitted. The Alberta Court of Appeal reversed and convicted; the Supreme Court restored the acquittal. Companion appeals R. v. Sullivan and R. v. Chan, 2022 SCC 19, were decided together.

Holding. Kasirer J. for a unanimous Court held that the 1995 s. 33.1 violated s. 7 in three ways and s. 11(d) as well. It permitted conviction without voluntariness, a principle of fundamental justice; it permitted conviction without the minimum constitutionally required fault for a crime of violence, because the intention to become intoxicated is not the fault of the violent offence and the provision did not require even objective foreseeability of the risk of a violent loss of control (a marked departure); and it substituted the intent to become intoxicated for the fault of the violent offence, contrary to the Vaillancourt substitution rule. The provision was not saved by s. 1, principally because Parliament had less-impairing options, including a stand-alone offence of criminal intoxication or a provision keyed to the objective foreseeability of harm from the consumption.

Parliament’s response. Within six weeks Parliament enacted the current s. 33.1, which imposes liability only where the accused departed markedly from the reasonable standard of care in relation to the consumption of intoxicants, assessed by reference to the objective foreseeability of the risk that consumption could cause extreme intoxication and lead the person to harm another. The replacement provision has been applied in the lower courts; I located no Supreme Court ruling on its constitutionality as of 6 October 2026.

Effect on doctrine. Confirms every strand of this article: the Re B.C. Motor Vehicle Act prohibition on punishing the morally innocent, the Creighton marked-departure minimum for objective fault, and the Vaillancourt substitution rule. It is also the Court’s clearest modern articulation of voluntariness as a distinct principle of fundamental justice. It is the best recent case for examining how the fault floor constrains legislative design.

6.7 R. v. Goforth, 2022 SCC 25 (10 June 2022)

Facts and history. Goforth and his wife were foster parents in Saskatchewan of two young children; a four-year-old died and a two-year-old suffered bodily harm from dehydration and malnutrition. He was convicted by a jury of manslaughter (via failure to provide necessaries of life, s. 215, and criminal negligence) and of unlawfully causing bodily harm; the Saskatchewan Court of Appeal ordered a new trial on the ground that the jury charge on mens rea was deficient, in part because it did not adequately address his evidence that he was a secondary caregiver with a demanding work schedule.

Holding. The Supreme Court restored the convictions. Côté J. for the majority held that the charge, read as a whole, adequately conveyed that the fault for s. 215 is objective (a marked departure from what a reasonably prudent parent or caregiver would do in the circumstances) and that criminal negligence requires a marked and substantial departure; that personal characteristics such as being a secondary caregiver or being busy do not lower the standard, consistent with Creighton; but that the accused’s actual circumstances, including the division of caregiving responsibilities, are part of the setting in which the reasonable person is placed, and the charge permitted the jury to consider them. The Court reiterated that jury instructions need only be proper, not perfect.

Effect on doctrine. Confirms Creighton and Naglik; clarifies the characteristics/circumstances boundary in a manner that practitioners should study closely, since it shows how a fact that looks like a personal characteristic (limited caregiving role) can be reframed as a circumstance.

6.8 What has not changed

No Supreme Court decision since 2017 has revisited the “special stigma” category or extended it beyond murder, attempted murder and war crimes; none has adopted the Creighton minority view on personalization; and none has questioned the modified objective test. I located no 2023–2026 Supreme Court decision materially altering the fault doctrine discussed in this article (the Court’s recent homicide decisions have concerned evidence, self-defence, jury instructions and sentencing rather than the constitutional fault floor). If you encounter a claim that the floor has moved, treat it with scepticism and check the citation.

7. Practice connection

This Part is educational and does not concern any actual client or file.

Client interviews. The first interview in any criminal matter is in substance an element-by-element interview, and the fault element is where the client’s account matters most. In a theft under $5,000 case, the questions that go to “fraudulently” and “without colour of right” (Did you think you were entitled to it? Why? Did you intend to return it?) are questions about subjective fault; in a dangerous driving case, by contrast, the client’s insistence that “I didn’t realize” is relevant but not decisive, and the interview must instead reconstruct the circumstances a reasonable driver would have faced (visibility, traffic, signage, mechanical condition, any sudden medical event). Knowing which standard applies tells you what to ask.

Police investigations and statements. Police interviews are frequently aimed at establishing the fault element rather than the act, because the act is often admitted or undeniable. A statement in which an accused says “I knew he had a knife” or “I figured the gun was loaded” converts an objective-fault argument into a subjective one. Counsel who understand that a subjective admission is sufficient (though not necessary) proof of a marked departure (Beatty) will understand why the voluntariness and Charter admissibility of a statement can be the whole case.

Bail. After Zora, bail conditions must be tailored and restrained, and the offence of breaching them requires subjective fault. A show-cause submission that proposes conditions the client cannot realistically comply with invites a breach charge; a defence to a breach charge may rest on absence of knowledge or recklessness. The constitutional fault floor also informs the “secondary ground” analysis where the Crown relies on the gravity of the offence: manslaughter and dangerous driving causing death are grave in consequence but modest in fault, which is a legitimate submission.

Disclosure and pretrial applications. In objective-fault prosecutions, disclosure of material about the circumstances (collision reconstruction, weather, vehicle inspection, caregiving arrangements, professional standards in the relevant activity) is central, because the “circumstances” define the reasonable person’s situation. In subjective-fault prosecutions, disclosure of the accused’s communications and prior statements is more significant. A Charter notice challenging an offence’s fault element (rare but possible, for example in regulatory offences carrying imprisonment, or in future challenges to the new s. 33.1) must identify the principle of fundamental justice and the proposed remedy under s. 52(1).

Voir dires and trials. The jury charge on fault is the most common source of appellate error. In a manslaughter trial the judge must charge objective foreseeability of non-trivial bodily harm, not death; in a dangerous driving trial the judge must charge marked departure and must caution against reasoning from consequences (Roy); in a criminal negligence trial the judge must charge marked and substantial departure; in a murder trial the judge must charge subjective foresight. Goforth is the current authority on the standard for reviewing such charges. In a judge-alone trial, the same points are the backbone of closing submissions.

Sentencing. Fault re-enters at sentencing as the central component of moral blameworthiness under s. 718.1 (proportionality). The same manslaughter conviction may reflect anything from near-accident to near-murder, and the sentencing range reflects that; the objective-fault floor at conviction places a heavy burden on sentencing to achieve proportionality, a point the Creighton majority itself relied on. For assault and theft, the degree of deliberation and planning similarly drives the range.

Appeals. Misdirection on the fault element is an error of law giving the Crown a right of appeal from an acquittal (Chung) and the accused a ground of appeal from conviction. The characterization of the trial judge’s error as one of law (the content of the standard) or of mixed fact and law (its application) is frequently decisive.

Extradition. Fault doctrine arises indirectly: under the Extradition Act the extradition judge tests the record of the case against the elements of the corresponding Canadian offence, including its fault element, under the double-criminality principle. A request alleging a felony-murder-type offence from a jurisdiction that retains constructive murder must be matched to the Canadian offence of manslaughter or to s. 229 on the facts; this will be examined in later articles on extradition.

8. Critical Analysis: Moral Blameworthiness, Constitutional Values and Reform

8.1 Moral blameworthiness and the subjectivist–objectivist debate

The subjectivist position, associated in the English literature with Glanville Williams and in Canada most prominently with Don Stuart, holds that criminal punishment is justified only where the accused chose to do wrong, and that choice requires actual awareness of the relevant risk. Negligence, on this view, is at most a civil wrong, and to punish it criminally is to punish people for what they are (inattentive, slow, inexperienced) rather than for what they chose. The objectivist position, developed by H.L.A. Hart and in Canada defended by Patrick Healy, Kent Roach and others in various forms, answers that the capacity to take care is itself a basis for responsibility: a person who could have adverted to an obvious risk and did not has exercised a kind of choice, the choice not to attend, and society may fairly demand attention from those who undertake dangerous activities. Hart’s qualification is important and is the theoretical root of the “capacity” exception in Creighton: negligence liability is fair only if the accused had the capacity to meet the standard. Both positions accept that objective liability must be confined to serious departures; the “marked departure” rule is the doctrinal expression of that shared premise.

A fair assessment is that Canadian law has adopted a pragmatic objectivism: subjective fault is the presumptive standard as a matter of interpretation and the required standard for a tiny constitutional category, while Parliament is free to adopt objective standards elsewhere, subject to the marked-departure minimum. Whether that settlement is principled or merely workable is a legitimate seminar question. The strongest subjectivist critique is that the constitutional minimum protects almost no one, because the offences it covers already required subjective fault at common law; the strongest objectivist reply is that a broader constitutional rule would have disabled Parliament from addressing road deaths, child neglect and workplace deaths through the criminal law at all.

8.2 Constitutional values and institutional competence

The s. 7 fault cases raise the question of who should decide the content of fault: Parliament, through the democratic process, or the courts, through an open-textured constitutional guarantee. McIntyre J. in Vaillancourt and L’Heureux-Dubé J. in Martineau argued for judicial restraint; the majorities answered that the Charter had deliberately placed the principles of fundamental justice beyond ordinary legislative revision. The dialogue that followed is instructive: Parliament took thirty years to repeal s. 230 but only six weeks to replace s. 33.1 after Brown, and the replacement was carefully drafted to the Court’s own specifications. Students of institutional dialogue can read that sequence either as a healthy constitutional conversation or as evidence that the Court, by signalling in advance what would be acceptable, has become the effective drafter of criminal fault.

8.3 Theories of punishment

Retributive theory supports both the murder rule (the label must fit the desert) and the critique of manslaughter (a four-year minimum for an objectively foreseeable but unforeseen death is hard to square with desert). Deterrence theory supports objective standards for regulated activities: drivers and caregivers are more likely to take care if care is legally demanded. Expressive or communicative theories (associated with Antony Duff) suggest that the label of an offence should communicate the nature of the wrong, which lends support to the stigma analysis while also exposing its circularity. Worth noting is that the Supreme Court in Creighton explicitly relied on the sentencing stage to supply proportionality that the conviction stage does not; a theorist would ask whether proportionality deferred is proportionality denied.

8.4 Prosecutorial and police discretion

The breadth of manslaughter and the objective-fault offences gives the Crown significant discretion in charge selection: the same death may be charged as murder, manslaughter by unlawful act, manslaughter by criminal negligence, or dangerous operation causing death. British Columbia’s charge-assessment standard (substantial likelihood of conviction and public interest, in the Crown Counsel policy) is where that discretion is formally structured, but the doctrinal reality is that lowering the fault floor transfers power from juries to prosecutors, because a lower floor makes more charges viable and increases the incentive to plead to a lesser offence. This is one of the least-discussed consequences of Creighton and a strong seminar topic.

8.5 Equality, systemic effects and Indigenous justice

The uniform reasonable-person standard was defended in Creighton as an expression of equality before the law. The critique, developed in the disability and critical-race literatures and in work on fetal alcohol spectrum disorder in Canadian criminal justice, is that a standard which refuses to account for cognitive limitations short of outright incapacity systematically disadvantages accused persons whose impairments are real but do not reach the threshold, and that these accused are disproportionately Indigenous, poor and under-served. Lamer C.J.’s minority approach would have mitigated this; the majority’s answer, that lowering the standard for some endangers everyone, is a serious one but it places the entire burden of individualization on sentencing, where R. v. Gladue, [1999] 1 S.C.R. 688 and R. v. Ipeelee, 2012 SCC 13 operate. The Javanmardi and Goforth refinements, by expanding what counts as “circumstances”, have quietly reintroduced some individualization, but in a way that tends to favour the skilled professional (whose experience raises the standard but whose reasonable reliance on that experience is credited) more readily than the cognitively impaired caregiver. A seminar paper could profitably examine whether the activity-sensitivity recognized in Javanmardi is doctrinally distinguishable from the frailty-sensitivity rejected in Creighton.

8.6 Access to justice, evidentiary reliability and procedural fairness

Subjective fault must usually be proven by inference from conduct and by statements. The reliability of confession evidence and the risk of false inference from after-the-fact conduct are therefore not peripheral evidence-law topics; they are the practical means by which the fault requirement is satisfied or defeated, and later articles on confessions and post-offence conduct should be read with this in mind. Objective fault shifts the evidentiary focus to expert and circumstantial evidence about what a reasonable person would have perceived, which raises its own reliability questions (reconstruction evidence; professional-standards evidence) and which tends to advantage well-resourced parties. Finally, the Chung dissent illustrates a procedural-fairness concern: an accused acquitted after a trial can be convicted on a Crown appeal if the trial judge’s reasoning is characterized as an error of law, and the law/fact line in fault cases is unusually porous.

8.7 Comparative and historical perspective

Canada’s constitutionalization of fault is unusual. English law has no equivalent; Parliament there abolished constructive malice in 1957 by statute and the courts have since oscillated on the objective/subjective line for recklessness (R. v. G, [2003] UKHL 50 restoring subjectivity). The United States retains felony murder in most states and the Supreme Court there has never held a fault requirement to be a constitutional minimum for ordinary offences, though the Eighth Amendment cases on the death penalty for felony-murder accomplices (Enmund; Tison) are a distant analogue to Martineau. The Model Penal Code’s hierarchy (purpose, knowledge, recklessness, negligence) is the clearest conceptual map of the vocabulary in 3.3 and is worth reading as a comparative reference even though Canada never adopted it. Historically, the Canadian cases were the Court’s first sustained use of s. 7 to review substantive criminal law, and their methodology (identify a principle of fundamental justice; test the provision against it; consider s. 1) is the template later applied to overbreadth and gross disproportionality in Canada (Attorney General) v. Bedford, 2013 SCC 72.

8.8 Arguments for and against reform

Three reform proposals recur. First, codification of the general part, including a statutory definition of the fault terms, as the Law Reform Commission of Canada recommended in its draft code of 1987 and as the Model Penal Code did; the argument for it is clarity and democratic ownership, the argument against is that it would freeze doctrine and that the common law has adapted adequately (the presumption of subjective fault, for instance, has been strengthened by A.D.H. and Zora without legislation). Second, raising the fault requirement for manslaughter to objective foreseeability of death (the Creighton minority), or creating gradations of manslaughter; the argument for it is proportionality and the argument against is that the four-year firearms minimum already distinguishes the gravest cases and that juries manage the distinction in practice. Third, legislating a personalized objective standard; the argument for is equality in substance, the argument against is the Creighton majority’s protective rationale and the difficulty of drawing the line. Present competing views fairly in a seminar; none is settled law.

9. Doctrinal synthesis

9.1 Governing rule

9.2 Step-by-step framework

1. Identify the offence and parse its actus reus into conduct, circumstances and consequences.
2. For each element, identify the fault required: (a) read the text for fault words; (b) if silent, apply the presumption of subjective fault (A.D.H.; Zora); (c) if the text or context indicates an objective standard (regulated activity; “dangerous”; “reasonable”; duty-based offences such as s. 215), apply the marked-departure standard; for s. 219, marked and substantial.
3. For consequence elements in predicate-based offences (ss. 222(5)(a), 267(b), 268, 269, 320.13(2)–(3)), apply objective foreseeability of the relevant harm (bodily harm neither trivial nor transitory for manslaughter; bodily harm for s. 269; no further fault for the driving consequences beyond causation).
4. Ask whether the offence falls in the constitutional “special stigma” category (murder, attempted murder, war crimes). If so, subjective foresight of the consequence is required regardless of text.
5. Apply the chosen standard to the evidence: for subjective fault, infer from conduct, statements and surrounding circumstances; for objective fault, define the reasonable person’s circumstances (including reasonable mistakes of fact and the nature of the activity), then ask whether the departure was marked (or marked and substantial), without reasoning backwards from consequences.
6. Consider element-negating defences (mistake of fact for subjective elements; reasonable mistake of fact and incapacity for objective elements) and the evidential burden to raise them.
7. If a constitutional challenge is contemplated, identify the principle of fundamental justice infringed, the s. 11(d) substitution point if applicable, the s. 1 argument, and the s. 52(1) remedy.

9.3 What elements must the Crown prove? (exemplar offences)

9.4 Burdens and standards

The Crown bears the persuasive burden on every element, including fault, to the standard of proof beyond a reasonable doubt. The accused bears an evidential burden (air of reality) to put a defence in play; where the defence negates an element (mistake of fact), the Crown must then disprove it beyond a reasonable doubt. The only persuasive burden on an accused relevant here is the due-diligence defence to a strict-liability regulatory offence (balance of probabilities), which Wholesale Travel upheld under s. 1.

9.5 Available defences or responses

Denial of the act or of voluntariness; honest mistake of fact (subjective elements) or honest and reasonable mistake of fact (objective elements); colour of right (theft); belief in consent (assault); absence of knowledge or recklessness (breach of release order); sudden incapacity or unforeseeable medical event (objective-fault offences); incapacity to appreciate the risk (Creighton); and, exceptionally, a constitutional challenge to the fault structure.

9.6 Common analytical errors

Treating “recklessness” in s. 219 as subjective; treating wilful blindness as “should have inquired”; applying a single mens rea to the whole offence rather than to each element; reasoning from the gravity of the consequence to the existence of fault (Roy); importing personal frailties into the objective standard (Creighton) or, conversely, ignoring the accused’s actual circumstances (Goforth); charging objective foreseeability of death rather than of bodily harm in manslaughter; forgetting that momentary conduct can still be a marked departure (Chung); and citing s. 249 or s. 230 as if still in force.

Q3. Explain the difference between the “marked departure” requirement and the “modified objective test”, and state which case is the principal authority for each.

Q4. For unlawful act manslaughter, what consequence must be objectively foreseeable, and what did Javanmardi clarify about “objective dangerousness”?

Case comparison

Q5. Compare the majority and minority positions in Creighton on (a) the consequence that must be foreseeable and (b) the personalization of the objective standard. Which position does Goforth apply, and does Javanmardi sit comfortably with it?

Q6. Beatty, Roy and Chung all concern dangerous driving causing death. Explain how Chung is reconciled with the earlier two.

Issue spotting

Q7. A provincial statute creates an offence of “operating a food premises in an unsanitary condition”, punishable by a fine of up to $25,000 or imprisonment for up to six months, and provides that “it is not a defence that the accused exercised due diligence”. Identify the constitutional issue and the likely result.

Q8. D, a courier, is paid $2,000 to drive a sealed package across the country, is told “don’t ask what’s in it”, notices it smells strongly of marijuana, and decides not to open it. The package contains cocaine. D is charged with possession for the purpose of trafficking. Identify the fault issue and the governing doctrine.

Practical hypothetical

Q9. At a house party, E, aged 19, punches F once in the face after an argument. F, who unknown to anyone has an unusually thin skull, falls, strikes his head on a concrete step and dies two days later. E says: “I only wanted to shut him up. I never thought he’d be hurt badly.” The Crown charges manslaughter. Advise on (a) the elements the Crown must prove, (b) the relevance of E’s statement, (c) the relevance of F’s thin skull, (d) whether E’s age or inexperience with fighting is relevant to the fault analysis, and (e) the relevance of the Charter.

Discussion question

Q10. “The constitutional fault requirement recognized in Vaillancourt and Martineau protects almost no one, because it applies only to offences that already required subjective fault, while Creighton licenses Parliament to criminalize inadvertence across the rest of the criminal law. The s. 7 fault jurisprudence is therefore more symbolic than substantive.” Evaluate this claim, with reference to Brown (2022).

11. Model answers

A1. Where a true crime is silent as to fault, the court presumes that Parliament intended subjective mens rea (intention or knowledge, with recklessness sufficient) in relation to the elements of the offence, and the presumption is displaced only by a clear indication in the text, context or scheme of the provision. The leading modern authorities are R. v. A.D.H., 2013 SCC 28 (child abandonment, s. 218) and R. v. Zora, 2020 SCC 14 (breach of release condition). It is an interpretive rule, not a constitutional one: Parliament may displace it by clear language, subject only to the much narrower s. 7 minimum (no absolute liability with imprisonment; marked departure for objective fault; subjective foresight for murder). The distinction matters because a textually objective offence outside the special-stigma category is valid even though it departs from the presumption.

A2. First, a s. 7 defect: the provisions permitted a murder conviction without the minimum fault that the principles of fundamental justice require for that offence (objective foreseeability of death in Vaillancourt; subjective foresight in Martineau), so that a person without the required blameworthiness could be stigmatized and punished as a murderer. Second, a s. 11(d) defect: the provisions substituted proof of a different fact (use of a weapon during a listed offence; intention to cause bodily harm to facilitate a listed offence) for proof of the essential fault element, and proof of the substituted fact did not lead inexorably to the existence of the essential element, infringing the presumption of innocence. Both defects were held unjustified under s. 1. The substitution analysis was applied again in Brown (2022) to the 1995 s. 33.1.

A3. The marked departure requirement is a requirement of degree: in an objective-fault true crime, the Crown must prove that the accused’s conduct fell markedly below the standard of the reasonable person, so that mere civil negligence or a momentary lapse does not suffice; the principal modern authorities are Beatty (2008) and Roy (2012), building on Hundal and Creighton. The modified objective test is a requirement of perspective: it defines the reasonable person as one placed in the accused’s actual circumstances, including the activity, the facts confronted and any honest and reasonable mistake of fact, but not endowed with the accused’s personal characteristics short of incapacity; the principal authorities are Hundal (origin) and Creighton (content). A complete analysis applies both: first fix the perspective, then measure the degree of departure.

A4. The Crown must prove objective foreseeability of the risk of bodily harm that is neither trivial nor transitory; foreseeability of death is not required (Creighton, majority). Javanmardi clarified that the “objective dangerousness” of the unlawful act, which DeSousa had mentioned and some courts had treated as a separate actus reus element, is not an independent requirement: the actus reus is simply an unlawful act that causes death, and dangerousness is captured entirely by the objective-foreseeability fault requirement. It also confirmed that the standard is informed by the activity undertaken, so that an accused’s experience within a skilled activity is part of the circumstances.

A5. (a) The majority (McLachlin J.) held that foreseeability of non-trivial bodily harm suffices; the minority (Lamer C.J.) would have required objective foreseeability of death, reasoning from the stigma of a homicide conviction and the symmetry principle. (b) The majority held that the reasonable person is not endowed with the accused’s personal characteristics (youth, inexperience, education, temperament) except where the accused lacked the capacity to appreciate the risk; the minority would have personalized the standard for “human frailties” not themselves culpably acquired. Goforth applies the majority: being a busy secondary caregiver does not lower the standard, though the actual division of caregiving responsibility is part of the circumstances in which the reasonable caregiver is placed. Javanmardi is formally consistent with the majority (the standard is not reduced for personal deficits) but it credits the accused’s professional experience as part of the “activity” and “circumstances”, which arguably individualizes the standard in the accused’s favour; whether that is distinguishable in principle from the frailty-sensitivity rejected in Creighton is a fair subject of debate, and a defensible answer may go either way provided it identifies the characteristic/circumstance distinction as the hinge.

A6. Beatty and Roy establish that a momentary lapse of attention or a single error of judgment, even with fatal consequences, will ordinarily not amount to a marked departure, and that the trier must not reason from the consequences back to fault. Chung does not depart from those propositions; it holds that the trial judge erred in law by treating the momentary duration of the conduct as if it were legally incapable of constituting a marked departure. The reconciliation is that momentariness is a feature of the circumstances relevant to what a reasonable person would have foreseen and done, not a rule of law; a brief but deliberate and extreme act (accelerating to nearly three times the limit toward an intersection) is qualitatively different from an inadvertent drift across the centre line. Note the dissent’s view that the error was one of application rather than law, which affected the Crown’s right of appeal.

A7. The provision excludes the due-diligence defence, which makes the offence one of absolute liability in Sault Ste. Marie terms; combined with the availability of imprisonment, it engages the liberty interest and is contrary to the principle of fundamental justice recognized in Re B.C. Motor Vehicle Act that the morally innocent not be imprisoned. The likely result is a declaration under s. 52(1) that the provision is of no force or effect to the extent that it excludes due diligence or to the extent that imprisonment is available; the s. 1 argument would almost certainly fail, since the regulatory objective can be achieved by a strict-liability offence (Wholesale Travel). A subtler point: if the legislature removed the possibility of imprisonment (and any default imprisonment for non-payment of the fine), absolute liability would be constitutionally tolerable (R. v. Pontes, [1995] 3 S.C.R. 44).

A8. The offence requires knowledge of the nature of the substance possessed (subjective fault; Beaver). D did not actually know the package contained cocaine, and D’s belief that it contained marijuana is a mistake of fact as to the nature of the substance. The governing doctrine is wilful blindness (Sansregret; Briscoe): if D’s suspicion was aroused to the point that D saw the need to inquire and deliberately refrained from inquiring because D preferred not to know, D is treated as having knowledge. Two refinements make the answer more sophisticated. First, wilful blindness is deliberate ignorance, not negligent failure to inquire; the trier must find a subjective decision not to look. Second, there is an argument that D’s wilful blindness extends only to the existence of a controlled substance, not its identity; the courts have generally held that knowledge that one possesses some controlled substance suffices for possession of the controlled substance actually possessed, but that point will be examined in a later article on drug offences and should be flagged rather than assumed.

A9. (a) Unlawful act manslaughter (s. 222(5)(a); s. 234): the Crown must prove the unlawful act (assault, s. 265: intentional application of force without consent, which is subjective and admitted on E’s account), that the assault caused F’s death (factual and legal causation; the single punch leading to the fall and head injury is a contributing cause outside the de minimis range, a topic for the article on causation), and objective foreseeability of the risk of bodily harm that is neither trivial nor transitory (Creighton; Javanmardi). A reasonable person would foresee that a punch to the face at a party, near a concrete step, risks non-trivial bodily harm; foreseeability of death is not required. (b) E’s statement is relevant to the subjective fault for the assault (it concedes intention to apply force) and is not a defence to the consequence, since the fault for the consequence is objective; it may be relevant to sentence. (c) The thin skull is irrelevant to liability: the accused takes the victim as found (causation), and Creighton expressly used the thin-skull rule to explain why symmetry is not required. (d) E’s age and inexperience are personal characteristics that do not lower the objective standard under the Creighton majority; they would be relevant only if they amounted to incapacity to appreciate the risk, which they do not; they are relevant to sentence. (e) The Charter offers no assistance: Creighton upheld this fault structure under s. 7, and no subsequent case has reopened it. A complete answer would add that the Crown might alternatively charge assault causing bodily harm or, if the evidence supported foresight of death, murder under s. 229(a)(ii), but on E’s account the latter is unavailable.

A10. A strong answer takes the claim seriously, grants its descriptive core, and then qualifies it. The descriptive core is correct: the special-stigma category covers murder, attempted murder and war crimes, each of which required subjective fault at common law, and the practical effect of Vaillancourt and Martineau was to strike provisions (s. 213/230; the objective words in ss. 212(c)/229(c) and 21(2)) that were statutory derogations from the common law, not to raise the general standard. Creighton then confirmed that Parliament may use objective standards everywhere else. On this view the jurisprudence is a constitutional ratchet applied to a handful of anomalous provisions. The qualification is that the “floor” has more content than the claim allows. It includes the Re B.C. Motor Vehicle Act prohibition on absolute liability with imprisonment, which affects the entire regulatory field; the requirement that objective fault in a true crime be penal negligence (marked departure), which constrains how Parliament may draft objective offences; the s. 11(d) substitution rule, which prevents Parliament from evading the fault requirement by deeming provisions; and, as Brown demonstrates, the voluntariness principle. Brown is the decisive counter-example: the 1995 s. 33.1 was struck precisely because it fell below these minimums, and Parliament’s replacement had to be drafted to a marked-departure, objective-foreseeability specification that the Court had effectively dictated. That is substantive, not symbolic. A sophisticated answer would nevertheless concede that the floor operates mainly as a constraint on legislative drafting rather than as a protection for individual accused in ordinary cases, and that the stigma rationale remains undertheorized; and it might note the institutional point that the Court’s willingness to signal acceptable alternatives (in Brown) makes the jurisprudence a dialogue rather than a barrier. There is no single correct conclusion; the quality of the answer lies in distinguishing the symbolic from the substantive components of the doctrine and in using Brown as evidence on both sides.

12. One-page review sheet

Essential rules

Fault attaches to each element of the actus reus separately. Text governs; silence triggers the presumption of subjective fault (recklessness suffices; wilful blindness = knowledge). Objective fault in a true crime requires a marked departure from the reasonable person placed in the accused’s circumstances (modified objective test), not personalized except for incapacity; s. 219 requires a marked and substantial departure. Section 7 forbids absolute liability with imprisonment, requires subjective foresight of death for murder (and subjective intent for attempted murder and war crimes), and, with s. 11(d), forbids substituting another fact for the fault element. Symmetry between actus reus and mens rea is not constitutionally required; consequence elements in predicate offences require objective foreseeability of the relevant harm (bodily harm neither trivial nor transitory for manslaughter).

Leading authorities

Re B.C. Motor Vehicle Act [1985] 2 SCR 486 · Vaillancourt [1987] 2 SCR 636 · Martineau [1990] 2 SCR 633 · Logan [1990] 2 SCR 731 · DeSousa [1992] 2 SCR 944 · Hundal [1993] 1 SCR 867 · Creighton [1993] 3 SCR 3 · Beatty 2008 SCC 5 · Roy 2012 SCC 26 · A.D.H. 2013 SCC 28 · Javanmardi 2019 SCC 54 · Chung 2020 SCC 8 · Zora 2020 SCC 14 · Brown 2022 SCC 18 · Goforth 2022 SCC 25 · Sansregret [1985] 1 SCR 570 · Briscoe 2010 SCC 13 · Buzzanga (1979) 49 CCC (2d) 369 (Ont CA).

Key distinctions

Recklessness (subjective, consequence) vs. wilful blindness (deliberate ignorance, fact) vs. criminal negligence (objective despite “reckless”). Marked departure (degree) vs. modified objective test (perspective). Characteristics (excluded) vs. circumstances (included). Presumption of subjective fault (interpretive) vs. constitutional requirement (murder only). Strict (due diligence) vs. absolute (none) liability. General/specific intent is an intoxication classification, not a fault standard.

Statutory provisions

Charter ss. 1, 7, 11(d), 52(1). Criminal Code ss. 21(2), 33.1 (2022), 215, 219–222, 229 (amended 2019), 230 (repealed 2019), 234, 236, 265, 322, 334, 320.13 (replacing 249, 18 Dec 2018), 320.19–320.21.

Five points to remember

1. Ask “what fault for which element?” before anything else; assault and theft are wholly subjective, dangerous operation is wholly objective, manslaughter is mixed, murder is subjective by constitutional command.
2. Momentary lapse is usually not a marked departure (Beatty, Roy), but momentary extreme conduct can be (Chung); never reason from consequences to fault.
3. The reasonable person is placed in the accused’s circumstances and activity (Javanmardi, Goforth) but does not share the accused’s frailties short of incapacity (Creighton).
4. Substituted proof of fault is a s. 11(d) problem independent of s. 7 (Vaillancourt; Brown).
5. Update your citations: s. 320.13 not 249; s. 230 repealed; s. 229(c) amended; s. 33.1 replaced (2022); s. 145(5) for breach of release order.

Three issues requiring further thought

1. Is the activity-sensitivity of Javanmardi principled, or is it Creighton‘s rejected personalization under another name?
2. Does deferring proportionality to sentencing (the Creighton majority’s answer to the objective-fault critique) survive the four-year firearms minimum in s. 236 and the broader mandatory-minimum jurisprudence?
3. After Brown, is the s. 7 fault floor a genuine constraint on Parliament or a drafting specification the Court supplies in advance?

Frequently Asked Questions

What is mens rea in Canada?

Mens rea is the mental element, or the fault element, that must attach to the actus reus of an offence. Canadian law does not have a single mens rea for an offence; it has a fault requirement for the conduct, a fault requirement for each circumstance, and, where there is one, a fault requirement for the consequence. Motive is generally irrelevant to liability, though relevant to proof and to sentence.

What is the presumption of subjective fault?

The presumption of subjective fault is an interpretive rule that a true crime is presumed to require subjective mens rea in relation to its elements, absent a clear legislative indication to the contrary. Recklessness suffices unless the offence specifies a higher form. The Supreme Court reaffirmed it in R. v. A.D.H., 2013 SCC 28 and R. v. Zora, 2020 SCC 14. It is not a constitutional rule: Parliament may displace it by clear language.

What state of mind is required for a murder conviction in Canada?

Every route to murder requires subjective foresight of death, as the Supreme Court held in Martineau. Under s. 229, the accused must mean to cause death; or mean to cause bodily harm the accused knows is likely to cause death, being reckless whether death ensues; or, for an unlawful object, do anything the accused knows is likely to cause death. The “ought to know” alternative in s. 229(c) was removed in 2019.

What does the Crown have to prove for unlawful act manslaughter?

The Crown proves the underlying offence with its own mens rea, causation of death, and objective foreseeability of the risk of bodily harm that is neither trivial nor transitory. Foreseeability of death is not required (Creighton). The unlawful act must not be an offence of absolute liability, and Javanmardi clarified in 2019 that “objective dangerousness” is not a free-standing element of the actus reus.

What is a “marked departure” in dangerous driving cases?

A marked departure is a requirement of degree: the accused’s conduct must fall so far short of the reasonable standard that it merits criminal condemnation. Civil negligence, such as a momentary lapse or a simple error of judgment, is not enough. For dangerous operation of a conveyance under s. 320.13, the mens rea is a marked departure from the standard of care of a reasonable person in the accused’s circumstances.

Can a few seconds of bad driving lead to a dangerous driving conviction?

It can, although a momentary lapse of attention is usually not a marked departure. Beatty and Roy hold that a momentary lapse or a single error of judgment, even with fatal consequences, will ordinarily not amount to a marked departure, and the trier must not reason from consequences back to fault. Chung (2020) added that brief but extreme conduct, such as accelerating to nearly three times the limit toward an intersection, can be one.

Can age or inexperience lower the standard for an objective fault offence?

No; on the majority view in Creighton, personal characteristics such as inexperience, lack of education, youth, low intelligence or impulsivity do not lower the standard. The only exception is incapacity to appreciate the risk. The reasonable person is, however, placed in the accused’s circumstances, including any honest and reasonable mistake of fact, and Javanmardi (2019) holds that the standard is informed by the activity undertaken.

What is the difference between recklessness and wilful blindness?

Recklessness is conscious disregard of a known risk, while wilful blindness is deliberate avoidance of confirming a strongly suspected fact and is equated with knowledge. Under R. v. Briscoe, 2010 SCC 13, the test is whether the accused’s suspicion was aroused to the point where the accused saw the need for further inquiries but deliberately chose not to make them. Wilful blindness is not “should have inquired”, which is negligence.

Can a person be imprisoned for an absolute liability offence in Canada?

No. In Reference re Section 94(2) of the Motor Vehicle Act (B.C.), [1985] 2 S.C.R. 486, the Supreme Court held that a person may not be imprisoned for an absolute liability offence, because imprisoning the morally innocent offends the basic tenets of our legal system. Strict liability, which permits a due-diligence defence on a balance of probabilities, is different: only absolute liability is constitutionally barred where imprisonment is possible.

Is extreme intoxication a defence to assault in Canada?

Not where the current s. 33.1 applies. R. v. Brown, 2022 SCC 18 struck down the 1995 version of s. 33.1. The replacement, in force 23 June 2022, provides that a person who lacks the general intent or voluntariness because of self-induced extreme intoxication still commits an offence involving an assault if, before becoming extremely intoxicated, the person departed markedly from the reasonable standard of care regarding the consumption of intoxicating substances.
