Executive Summary: Key Legal and Evidentiary Issues

• Interaction between a Solicitors Act assessment of legal fees and a separate solicitor’s negligence action, and whether one forecloses the other.
• Effect of a negligence trial judgment (finding no negligence) and principles of res judicata and issue estoppel on the remaining fee assessment, particularly the Cohen v Kealey & Blaney factors.
• Whether an administratively dismissed assessment proceeding, adjourned sine die pending a negligence trial at the firm’s request, should be restored under rule 37.14.
• Allocation of litigation delay responsibility where the assessment was stayed at the law firm’s instance, and the impact of that history on setting aside the administrative dismissal.
• Extent to which the negligence findings bind the assessment officer on issues of quality of work and competence, while leaving open the independent inquiry into reasonableness of fees.
• Consequences of litigation misconduct (fabricated case law, questionable affidavit evidence) on costs entitlement despite success on the motion.

Background and parallel proceedings

The dispute arises from the professional relationship between the applicant, Yue Gu, and the law firm Fogler, Rubinoff LLP. In August 2017, Mr. Gu commenced an assessment of the firm’s accounts under the Solicitors Act, challenging the reasonableness of the fees charged for work performed by the firm and its lawyer, Ms. Huang. The assessment proceeding is a statutory mechanism allowing a client to have a court officer review the amount and fairness of a lawyer’s bill.
In September 2018, Mr. Gu also started a separate civil negligence action against the firm, alleging that the firm’s conduct went beyond a mere disagreement over fees and rose to negligence, breach of contract, and breach of fiduciary duty, with a pleaded damages claim of $3 million. Over time, the damages theory in the civil action narrowed, and by trial the main claim concerned the difference between the security for costs relief he said he should have received and what was actually ordered.
By August 2019, all materials in the fee assessment were complete and the matter was ready to proceed. At that point, the firm brought a motion before the assessment officer seeking a stay of the assessment until after the negligence action was determined. The assessment officer did not terminate or consolidate the assessment; instead, he adjourned it sine die—without a fixed return date—to allow the negligence action to proceed and to avoid potential res judicata problems. The assessment thus remained in abeyance, not dismissed, while the civil action moved forward.

Outcome of the negligence action

The negligence action eventually proceeded to trial. In December 2022, the trial judge dismissed Mr. Gu’s negligence claim and found that Fogler, Rubinoff LLP and Ms. Huang were not negligent in respect of the matters for which they had been retained. The firm was successful at trial, and the action was dismissed with costs against Mr. Gu. The reasons in Gu v Huang 2022 ONSC 7150, as summarized in the 2026 decision, confirm that the trial judge understood the ongoing existence of the separate fee assessment; the statement of claim itself described the Solicitors Act assessment as a distinct process. The trial judge also noted that the plaintiffs were seeking findings at the negligence trial that could assist them in lowering the bill at the later assessment, underscoring that the assessment had not merged into the civil proceeding.
Importantly, while the negligence trial addressed the quality of the legal services and whether the firm’s conduct fell below the standard of care, it did not determine the reasonableness of the firm’s fees under the statutory assessment framework. The trial focused on negligence and damages, not on an item-by-item or overall review of the accounts under the Cohen v Kealey & Blaney factors, such as time spent, complexity, responsibility assumed, monetary value of the matter, and the client’s expectations and ability to pay. As a result, the trial judgment resolved the negligence allegations but did not extinguish the client’s independent right to have the fees reviewed in the assessment.

Administrative dismissal of the assessment

While the negligence proceedings were still winding their way through the appellate process, an administrative event intervened in the assessment case. On June 6, 2024, the fee assessment—still adjourned and effectively stayed because of the earlier sine die order—was administratively dismissed. This was not the result of a contested motion but of the court’s administrative process, triggered during a period when the negligence action had not yet reached its final conclusion, as the Supreme Court of Canada did not dismiss Mr. Gu’s leave application until October 3, 2024.
Upon learning of the administrative dismissal, Mr. Gu promptly sought Fogler, Rubinoff’s consent to reinstate the assessment. The firm refused. The applicant then moved under rule 37.14 of the Rules of Civil Procedure to set aside the administrative dismissal and restore the assessment for hearing. The motion thus squarely raised issues of delay, intention to proceed, responsibility for the procedural posture of the assessment, and potential prejudice to the firm.

Res judicata, issue estoppel, and scope of the assessment

Fogler, Rubinoff opposed restoration of the assessment on the basis that all issues regarding their fees and conduct had effectively been determined in the negligence trial. They argued that the negligence decision, which found no negligence and dismissed the plaintiff’s action with costs, should operate as a complete bar to relitigating any issues relating to the fees or the firm’s performance. In their view, the assessment was subsumed by, or entirely overlapping with, the negligence action.
Associate Justice Jolley rejected this position in part. She agreed that the negligence findings are res judicata: it is no longer open to Mr. Gu, in the assessment, to attack the quality of the legal work or to allege that the firm’s conduct was negligent. The applicant is bound by the trial judge’s determination that the firm was not negligent in any of the matters for which it had been retained, and those issues cannot be revisited in the assessment.
However, the decision draws a clear distinction between (a) negligence and (b) the broader statutory question of whether the fees are reasonable, as guided by the Cohen v Kealey & Blaney framework. The assessment officer must consider factors beyond the firm’s conduct or standard of care: time spent, legal and factual complexity, the significance and monetary value of the matter to the client, the degree of responsibility assumed, and the client’s expectations and ability to pay. The negligence court did not address these elements and was not asked to do so; therefore, issue estoppel does not apply to those aspects of the fee review.
The court contrasted the present case with Susin v Baker, where a completed assessment—including consideration of alleged negligence—preceded a negligence lawsuit and effectively determined all issues, justifying a stay of the subsequent negligence action. Here the sequencing was reversed: negligence was decided first while the assessment factors remained untouched. Had the firm allowed the assessment to proceed before the negligence trial, the outcome might have been different, with res judicata flowing from the assessment rather than from the negligence action.

Delay, responsibility, and restoration under rule 37.14

On the core procedural question—whether to set aside the administrative dismissal—Associate Justice Jolley found that Mr. Gu met the criteria for relief. The material showed that he had always intended to proceed with the assessment and had not abandoned the process. The assessment had been fully prepared for hearing as of August 2019. The only reason it did not proceed at that time was the firm’s own request to adjourn the assessment sine die pending the negligence trial.
The court held that any litigation delay in the assessment proceeding was largely attributable to the firm’s motion and the resulting adjournment, rather than to any lack of diligence by the applicant. After the adjournment order, Mr. Gu could not move the assessment forward without violating the assessment officer’s direction; he was effectively constrained from taking steps until the negligence proceedings concluded. Once the assessment was administratively dismissed, the applicant moved promptly: he immediately sought the firm’s consent and, when that was refused, brought this motion without delay.
In considering prejudice, the court noted that the assessment record had been complete for about six years and that, but for the firm’s request for adjournment, the assessment would have been heard back in 2019. The firm could not show any non-compensable prejudice flowing from restoration of the assessment. Given the completed record and the original scheduling, the equities favoured allowing the assessment to proceed. The court concluded that, in all the circumstances, it would be unjust to deny the applicant his statutory right to have the fees assessed.

Litigation misconduct and the costs outcome

Despite the applicant’s success on the motion, the court took a strict view of his and his daughter’s litigation conduct. When the motion first came before Associate Justice Jolley, the firm pointed out that it could not locate at least two reported cases that were cited at length in the applicant’s factum. Investigation revealed that these cases did not exist. Mr. Gu’s daughter—who is not a lawyer and who had prepared the factum—ultimately conceded that the “authorities” were generated by AI, apparently to bolster the applicant’s legal submissions. The factum was then withdrawn and replaced by an aide-mémoire.
The court regarded this as serious and unacceptable conduct. If the applicant or his daughter had been lawyers, this behaviour would likely have attracted the jurisdiction of the Law Society. Additionally, the affidavit filed in support of the motion lacked a certificate of translation, even though Mr. Gu does not read English and the affidavit was drafted by his daughter, raising concerns about whether it accurately reflected his own evidence. While these factors did not lead the court to dismiss the motion, they were weighed heavily in the costs analysis.

Overall result and monetary consequences

In the 2026 motion decision, Associate Justice Jolley granted Mr. Gu’s motion to set aside the administrative dismissal and restore the fee assessment, but ordered that the motion proceed without costs—meaning the successful moving party received no costs award because of his and his daughter’s litigation misconduct. In contrast, in the earlier negligence action, the firm had been entirely successful: the negligence claim was dismissed with costs against Mr. Gu. The exact dollar amounts of those trial costs, or of any related awards, are not set out in the text available here, and no damages were awarded to Mr. Gu in that action. Consequently, based on the materials at hand, the successful party in the negligence case was Fogler, Rubinoff LLP, with a costs award in its favour in an unspecified amount, while in the 2026 motion the successful party was the applicant, Yue Gu, but he obtained only procedural relief and no monetary award or costs in his favour, and the precise total of all costs or damages ordered across the proceedings cannot be determined from the decision excerpt alone.
