If you are an Ontario client who has just received a legal invoice that feels excessive — or a solicitor preparing to defend an account under challenge — there is one case you need to understand: Cohen v. Kealey & Blaney (1985), 26 C.P.C. (2d) 211 (Ont. C.A.).
This Ontario Court of Appeal decision set out the nine factors that every Assessment Officer in the province must consider when deciding whether a lawyer’s bill is fair and reasonable. Whether your file involves a six-figure commercial litigation account or a modest family law retainer, the Cohen framework is the legal lens through which your bill will be reviewed.
At Z Legal in Toronto, we regularly act for both clients challenging inflated accounts and for lawyers defending their fees. This guide explains the assessment process, walks through each of the nine Cohen factors, and offers practical advice for anyone facing a solicitor-client fee dispute in Ontario.
What Is a Solicitors Act Assessment in Ontario?
A Solicitors Act assessment is a formal process under Ontario’s Solicitors Act by which a client — or, in some cases, the lawyer — brings a disputed legal bill before a court-appointed Assessment Officer. The Officer independently reviews the account and determines what amount, if any, is fair and reasonable in the circumstances.
Assessments are heard at the Superior Court of Justice. The Officer is not bound to accept either the client’s position or the lawyer’s docketed time at face value. Instead, the Officer applies the nine-factor framework from Cohen v. Kealey & Blaney to reach a balanced conclusion.
Key takeaway: Fee assessment is not a mathematical exercise. It is a holistic weighing of multiple factors — any of which can move the final number up or down.
The 9 Cohen v. Kealey & Blaney Factors — Explained
No single factor is determinative. Assessment Officers weigh them together against the specific facts of your file.
- Time Expended by the Solicitor
The hours docketed to the file are the starting point — but never the finish line. Assessment Officers scrutinize whether the time was necessary, efficient, and properly recorded. Hours spent duplicating junior work, researching settled law, or over-preparing for routine steps can be disallowed.
- Legal Complexity of the Matter
Complex commercial litigation, novel constitutional questions, or intricate regulatory files justify higher fees than routine matters. Complexity is assessed both objectively and relative to the solicitor’s level of practice — what is complex for a junior may be routine for senior counsel.
- Degree of Responsibility Assumed by the Solicitor
This factor is examined in detail below — it is the most frequently contested of the nine.
- Monetary Value of the Matters in Issue
A dispute involving millions of dollars in exposure naturally warrants more resources than one involving modest sums. The quantum at stake is a legitimate input into the reasonableness of the fee.
- Importance of the Matter to the Client
Monetary value is not the only measure of importance. A child custody fight, a professional discipline proceeding, or a defamation action may carry profound personal, reputational, or career consequences that justify significant legal investment.
- Degree of Skill and Competence Demonstrated
Exceptional advocacy, strategic judgment, and technical mastery command higher fees. Conversely, poor drafting, missed deadlines, or inefficient work product can justify a fee reduction.
- Results Achieved
A favourable settlement, successful trial outcome, or strong risk mitigation supports the account. Poor results — particularly those traceable to avoidable errors — can weigh against it. Assessment Officers do, however, recognize the inherent unpredictability of litigation.
- Ability of the Client to Pay
This is not a means test. A fee does not become unreasonable simply because the client finds it burdensome. But the client’s financial circumstances, viewed alongside any retainer agreement, remain a relevant consideration.
- Client’s Expectation as to the Amount of the Fee
What did the client reasonably expect to pay? Retainer letters, fee estimates, and ongoing billing communications all shape this expectation. A client kept in the dark about escalating costs has strong grounds to challenge a surprise invoice.
Factor 3 in Depth: Degree of Responsibility
Factor 3 deserves special attention because it captures the breadth of a lawyer’s professional obligations throughout the retainer. As Assessment Officer Ittleman set out in Mok v. Abbass, [2013] O.J. No. 5160 (adopted with approval in Holmes v. Lerners LLP, 2014 ONSC 5449), the degree of responsibility includes:
- Retainer clarity — ensuring the client fully understands the retainer terms from the outset;
- Cost transparency — keeping the client informed of the status and running cost of the litigation;
- Informed decision-making — providing enough information for the client to make informed choices at every material juncture;
- Instructed steps — obtaining instructions on procedural and strategic decisions, with clear communication of the consequences;
- Settlement exploration — proactively raising settlement early and at every subsequent stage;
- Efficient delegation — pushing work down to the least expensive qualified timekeeper (associate, clerk, or paralegal) who can properly handle it; and
- Billing particularity — providing enough detail in accounts and reporting letters for the client to understand what was done and why.
Practice note from Z Legal: A solicitor who fails to delegate, neglects to canvass settlement, or delivers block-billed invoices with generic descriptions is highly exposed on Factor 3. In our experience, accounts are most often reduced at assessment not because the time wasn’t spent — but because the file wasn’t managed and documented in a way the Assessment Officer could defend on the record.
Key Ontario Authorities Governing Fee Assessments
| Case / Statute | Key Principle |
| Cohen v. Kealey & Blaney (1985), 26 C.P.C. (2d) 211 (Ont. C.A.) | The foundational 9-factor framework for every Solicitors Act assessment in Ontario. |
| Holmes v. Lerners LLP, 2014 ONSC 5449 | Adopted Assessment Officer Ittleman’s articulation of the Factor 3 responsibilities. |
| Mok v. Abbass, [2013] O.J. No. 5160 | Set out the detailed content of Factor 3, including delegation and billing particularity. |
| Cookish v. Paul Lee Associates Professional Corp., 2013 ONCA 278 | Assessment Officers have no jurisdiction to resolve genuine retainer disputes on requisition. |
| Paoletti v. Gibson, 2009 ONCA 71 | Confirmed the two exceptions: no real dispute, or dispute confined to quantum. |
| Solicitors Act, s. 5 (Ontario) | If a party fails to attend with proper notice, the Officer may assess the bill without further notice. |
What Happens at the End of an Assessment Hearing?
Interest on the Account
The Assessment Officer has discretion to award interest on any amount found owing. Both the rate and the start date are determined by the equities of the file.
Costs of the Assessment Itself
Either party may seek costs at the conclusion of the hearing:
- A client who substantially succeeds in reducing an inflated account may recover their costs of the assessment.
- A solicitor who successfully defends a reasonable bill may recover costs against a client who brought an unmeritorious challenge.
Costs awards rest entirely within the Officer’s discretion — which is why preparation and presentation matter so much.
Practical Guidance
For Toronto Clients Considering an Assessment
Before commencing an assessment, take the nine Cohen factors and apply them honestly to your file. Ask:
- Were you kept informed as costs escalated, or did the first real communication about quantum arrive with the final bill?
- Did your lawyer canvass settlement early — and document those discussions?
- Were routine tasks (document review, scheduling, form drafting) billed at partner rates that should have been delegated?
- Is each docket entry detailed enough that you can actually tell what was done?
- Did the results achieved justify the resources invested?
Strong answers to those questions often support a meaningful reduction. Weak answers may mean the account is, in fact, defensible.
For Solicitors Defending an Account
The strongest defence is built before the dispute arises:
- A clear, written retainer agreement signed at intake;
- Regular written cost updates (not just verbal reassurances);
- Settlement discussions memorialized on the file;
- Granular time dockets with meaningful narratives; and
- Appropriate delegation to associates, clerks, and paralegals.
A well-documented file with clear billing narratives is dramatically easier to defend than a block-billed account padded with generic descriptions.

Frequently Asked Questions
What is a Solicitors Act assessment in Ontario?
A Solicitors Act assessment is a formal process through which a client challenges a lawyer’s invoice before a court-appointed Assessment Officer. The Officer independently reviews the account and determines what amount, if any, is fair and reasonable. The nine factors from Cohen v. Kealey & Blaney govern that determination.
How do I dispute my lawyer’s bill in Ontario?
In most cases, you begin by obtaining an order for assessment from the Superior Court of Justice, typically on requisition. Strict time limits apply — in many situations, one month from the date of the bill — so it is important to act quickly and consult a litigation lawyer experienced in fee disputes before deadlines pass.
Can an Assessment Officer decide whether a retainer agreement is valid?
Generally, no. Under Cookish v. Paul Lee Associates (2013 ONCA 278), an Assessment Officer has no jurisdiction to resolve genuine disputes about the existence or terms of a retainer where the assessment is ordered on requisition — unless there is no real dispute, or the dispute is confined to the quantum of the bill.
What happens if one party doesn’t show up to the assessment?
Under section 5 of the Solicitors Act, if a party has received proper notice and fails to attend, the Assessment Officer may proceed and assess the bill without further notice, based on the material available.
Are all nine Cohen factors weighted equally?
No. The factors are weighed holistically against the facts of each file. Depending on the matter, factors such as results achieved or degree of responsibility may carry significantly more weight than others. A skilled litigation lawyer will know which factors to emphasize in your specific case.
Can I recover the costs of the assessment hearing itself?
Yes. Either party may seek an award of costs at the conclusion of the hearing. Whether and to what extent costs are awarded is entirely within the Assessment Officer’s discretion — which is why strong preparation and a well-organized record matter.
Does Z Legal handle fee assessments outside of Toronto?
Yes. While our office is based in Toronto, we act on Solicitors Act assessments throughout Ontario, including the GTA, Ottawa, and southwestern Ontario. Contact us to discuss your file.
