What Is the Legal Nature of the Retainer Contract?

A retainer agreement in Canada is fundamentally a contract for professional legal services. The Alberta Court of Queen’s Bench explicitly stated this contractual foundation in Guardian Law Group v LS, 2021 ABQB 591, noting at paragraph 22:

“A retainer agreement is a contract for legal services between a lawyer and a client. Principles of contract law apply to retainer agreements…”

However, this is not just an ordinary commercial transaction. Because the solicitor-client relationship imposes strict fiduciary duties on a lawyer, courts demand a significantly higher level of transparency. The Court of Appeal for Ontario emphasized this in Boudreau v. Lavery, De Billy LLP, 2022 ONCA 691, stating at paragraph 5:

“because a solicitor-client relationship imposes fiduciary duties on a lawyer, solicitor-client retainers are contracts that carry particular duties for lawyers to communicate clearly so that the client understands the terms of the retainer. If there is any ambiguity in a solicitor-client retainer, it is to be construed against the drafter – that is, the lawyer.”

Therefore, a comprehensive lawyer-client retainer and fee agreement identifies who the lawyer is, what tasks they are hired to complete, the boundaries of the work, how fees and expenses are calculated, who makes critical decisions, and how the relationship can safely end.

What Are the Contractual Obligations and Practical Effects?

A retainer constructs mutual obligations for both the lawyer and the client. The Court of Appeal of Newfoundland and Labrador clarified the origin of these specific duties in Fitzpatrick v Hefferman, 2019 NLCA 77, at paragraph 30:

“The origin of a solicitor’s duties is the retainer or contract of engagement between himself and the client. … The retainer, when given, puts into operation the normal terms of the contractual relationship, including in particular the duty of the solicitor to protect the client’s interest, and carry out his instructions in the matters to which the retainer relates, by all proper means.”

From a legal perspective, the most critical practical effects of a lawyer-client retainer and fee agreement include the following distinct elements:

1. Defining the Subject Matter and Scope of Representation

If a retainer is limited in scope, it must be expressed in completely unambiguous terms. As established in Fitzpatrick v Hefferman:

“A solicitor who wishes to limit the scope of his or her retainer bears the onus of doing so in unambiguous terms. Any ambiguity or doubt concerning the scope of the retainer will generally be resolved in favour of the client.”

2. The Lawyer’s Duty of Clear Communication regarding Contract Terms

If a specific clause heavily impacts the client’s substantive rights, the lawyer is legally obligated to actively explain it rather than simply burying it in the text. In British Columbia, the court in 1011173 B.C. Ltd. v Hakemi & Ridgedale LLP, 2021 BCSC 2485 observed:

“The periodic final billing provision was primarily if not exclusively for the benefit of the lawyers… In these circumstances, the lawyers were obliged to bring it to the clients’ attention and provide a reasonable explanation of how it would affect their ability to review the bills issued by the lawyers. The lawyers did not do so.”

3. The Client’s Obligation to Pay According to the Contract

Clients must pay specified fees, but the lawyer cannot arbitrarily claim amounts beyond the written terms. In Ontario, section 21 of the Solicitors Act, R.S.O. 1990, c. S.15 explicitly states:

“Such an agreement excludes any further claim of the solicitor beyond the terms of the agreement…”

This means unless the contract explicitly provides for exceptions, the lawyer cannot seek additional remuneration outside the agreed framework.

4. The Client’s Right to Transparent Billing and Review

Provincial regulations protect the client’s right to itemized invoicing. In British Columbia, sections 69(3)-(4) of the Legal Profession Act [SBC 1998] c. 9 establish:

“The bill must be signed by or on behalf of the lawyer…” and “is sufficient in form if it contains a reasonably descriptive statement of the services with a lump sum charge and a detailed statement of disbursements.”

Furthermore, section 70(1) of the same Act notes that “The person charged… may obtain an appointment to have a bill reviewed…” Similarly, under section 24 of the Ontario Solicitors Act, if the terms are deemed by a court not to be fair and reasonable, the agreement may be declared void.

Can a Client Terminate the Agreement?

Yes. The general overarching principle is that a client can change their legal counsel at any given time. Section 30 of the Ontario Solicitors Act states:

“If, after any such agreement has been made, the client changes solicitor before the conclusion of the business to which the agreement relates, which the client is at liberty to do despite the agreement…”

The Supreme Court of Newfoundland and Labrador expressed this right even more directly in Estate of P.J.O’N. v. M.C., 2016 NLMA 1, at paragraph 77:

“there is no rule against a client changing lawyers at will, whether for good cause or for no cause at all… the client’s right to change lawyers cannot be denied”

Consequently, any clause restricting this right within a lawyer-client retainer and fee agreement is highly problematic. In Ontario, section 8(b) of the Contingency Fee Agreements regulation explicitly commands:

“A solicitor shall not include in a contingency fee agreement a provision that… prevents the client from terminating the contingency fee agreement with the solicitor or changing solicitors”

In Saskatchewan, the court in One Arrow First Nation v Maurice Law, 2025 SKKB 88 confirmed that financial penalty clauses designed to prevent a client from changing counsel are completely unenforceable:

“The penalty provisions… are not fair or reasonable. They include serious financial consequences to the client for choosing alternate counsel… the practical reality is that the financial consequences of terminating Maurice may very well prevent the client from doing so.”

Can a Lawyer Terminate the Agreement?

Yes, but a lawyer cannot do so ambiguously or abandon a client mid-stream. The Court of Appeal of Newfoundland and Labrador in Fitzpatrick v Hefferman, at paragraph 33, outlined the strict rules:

“A lawyer who purports to terminate the solicitor-client relationship before the mandate resulting from the retainer is completed must therefore do so in clear and unambiguous terms…”

The court added that “Absent a clear termination by the lawyer, the relationship will be presumed to continue during which time the lawyer will remain under a duty to complete the work.” If a lawyer intends to withdraw, they must explicitly notify the client of what remains to be done, any pressing deadlines, and how the client can protect their interests, as paragraph 29 highlights:

“If a lawyer takes the position that he or she is unilaterally terminating the professional relationship, that position has to be clearly brought to the attention of the client so that the client can act to protect her interests in other ways.”

What Is the Difference Between Contractual Termination and Court Withdrawal?

If active litigation is ongoing in court, terminating the private contract does not automatically remove the lawyer from the public court record. In Ontario, Rule 15.05 of the Rules of Civil Procedure states:

“A lawyer of record shall act as and remains the lawyer of record for his or her client until… the client delivers a notice… or… an order removing the lawyer from the record has been entered…”

In British Columbia, Rule 22-6(1) of the Supreme Court Civil Rules mandates that until formal notices are filed and served, other parties are entitled to proceed on the basis that no change has occurred. Therefore, you must always distinguish between the private cancellation of the lawyer-client retainer and fee agreement and the formal procedural removal of a lawyer from court records.

How Are Ambiguities in the Agreement Resolved?

When analyzing a lawyer-client retainer and fee agreement, courts strictly apply the principle that any ambiguity is resolved against the drafter. Apart from Boudreau v. Lavery, the court in Janik v Stillman, 2016 ONSC 1801 reaffirmed:

“Where there is no written retainer agreement or letter confirming the scope of retainer, the solicitor cannot limit his mandate… Any ambiguity about the mandate shall be resolved against the solicitor.”

Simply put, if the contract fails to specify exactly what the lawyer will or will not do, the courts will reject restrictive interpretations that favor the lawyer.

Which Crucial Clauses Should You Read with a Magnifying Glass?

To fully protect yourself, you must carefully scrutinize these specific contractual components before signing any lawyer-client retainer and fee agreement:

• Scope of Work: Verify if the description covers consultations, negotiations, trial levels, or potential appeals, defining what the lawyer is responsible for.
• Fee Calculations: Understand if the structure is hourly, flat-fee, or a contingency percentage. In Boudreau v. Lavery, the entire dispute centered on whether a clause capped total fees or merely the premium; the court held that the clear words capped only the premium, showing how a single word creates massive financial impacts.
• Disbursements vs. Fees: Ensure third-party costs like filing fees, courier services, and taxes are clearly separated. Section 7(2)3 of Ontario’s Contingency Fee Agreements regulation requires a clear statement showing if the client is responsible for disbursements and taxes.
• Termination Consequences: Review what the lawyer receives if you terminate early (e.g., hourly rates or quantum meruit). Section 7(2)7 of the Ontario contingency regulation demands an explicit outline of termination consequences.
• Decision-Making Power: Ensure you retain ultimate control over major choices. Section 7(2)8 and Section 8(a) of the Ontario regulation dictate that a client retains the right to make all critical decisions and explicitly forbid clauses requiring a solicitor’s consent before settling or abandoning a claim.
• Assessment Rights: Check for your explicit right to challenge invoices. Section 7(2)5 of the Ontario regulation requires notifying the client of their right to ask the Superior Court of Justice to assess the bill.
• Negligence Liability Exclusions: Any clause attempting to eliminate a lawyer’s liability for professional negligence is completely invalid. Section 22(1) of the Ontario Solicitors Act and Section 65(3) of the BC Legal Profession Act both establish that a provision exempting a lawyer from liability for negligence is wholly void.

What Are the Red Flags to Watch Out For?

Be exceptionally cautious if your lawyer-client retainer and fee agreement contains any of the following warning signs:

• The scope of work uses excessively broad language while packing the contract with numerous hidden exclusions.
• Legal fees, third-party disbursements, and provincial taxes are entirely commingled without separation.
• The termination clause inflicts severe, crushing financial penalties designed to prevent you from changing counsel.
• The absolute right to settle or withdraw the legal claim is explicitly transferred to the lawyer.
• The agreement labels interim bills as completely “final” without setting out the actual legal significance and review processes, a failure heavily penalized in 1011173 B.C. Ltd. v Hakemi & Ridgedale LLP.

What Happens If the Agreement Is Unfair?

Canadian courts do not blindly enforce unfair retainer agreements. In Ontario, the Court of Appeal in Bimman v. Igor Ellyn Professional Corporation, 2022 ONCA 781, at paragraph 35, declared:

“the solicitor bears the onus of satisfying the court that the way in which the agreement was obtained was fair and that the terms of the agreement are reasonable.”

If the agreement fails this judicial test, section 24 of the Solicitors Act allows it to be declared void. Similarly, in British Columbia, sections 68(5)-(6) of the Legal Profession Act empower a registrar to modify or cancel any agreement deemed unfair or unreasonable.

Practical Summary: What Are the Six Questions Before Signing?

Before executing your formal lawyer-client retainer and fee agreement, ensure you have crystal-clear, written answers to these six fundamental questions:

1. What specific legal tasks is the lawyer explicitly hired to perform?
2. What related legal tasks does the lawyer explicitly exclude from their mandate?
3. How are fees, disbursements, taxes, and interest charges calculated line-by-line?
4. What exact amounts are payable, and on what basis, if either party terminates the relationship?
5. Who holds the final, definitive authority to approve a settlement or make critical case decisions?
6. What is the formal process and exact deadline to object to and review an invoice?

If any of these items remain vague, that ambiguity itself serves as a critical legal warning sign.
