Ontario – Application to set aside award in baseball arbitration denied – #940

In Stronach v. Stronach, 2025 ONSC 7158, the Parties, who had been embroiled in years of acrimonious litigation related to their family enterprise, agreed to a settlement that included a final-offer (or “baseball”) arbitration to determine the value of the Respondents’ agreed share of the businesses. The Applicants later challenged the arbitral award, which had been rendered by a prominent business valuator. They argued, among other things, that it should be set aside because the Arbitrator relied on an expert report, which was outside his jurisdiction because it did not comply with the valuation standards agreed to by the Parties. The Application Judge dismissed the application, describing it as “very weak” on the purported jurisdictional issue. In substance, he viewed it as a challenge to the merits of the award where there was no appeal. In any event, the Application Judge held that the Applicants had “agreed” to admit the impugned expert report into evidence to challenge its weight. By not objecting to the report’s admissibility at the hearing or to the Arbitrator’s authority to receive it, the Applicants waived their ability to later raise the jurisdictional argument on a setting aside application.

The case raises a number of procedural fairness issues, but this summary will focus on jurisdiction and waiver issues.

Alberta – Tribunal not functus officio when issuing award after final award – #932

In Lawrence v. Wood, 2025 ABKB 594, the Court dismissed an application for leave to appeal an award of an arbitral tribunal, or alternatively, to set it aside. The Applicants argued that that the tribunal was functus officio and lacked jurisdiction when it issued an award stating that a prior award was to be paid jointly and severally. The Court disagreed and held that the tribunal still had jurisdiction to make this clarification because this issue was dealt with “implicitly” in the first award, or alternatively, it was a new issue that was not before it when the first award was issued.

Ontario – Mid-arbitration switch to written hearing/refusing to consider submissions procedurally unfair – #915

In Spinney v. Fowlie, 2025 ONSC 2632, the Court set aside an award for want of procedural fairness. The Court found the applicants were denied fair and equal treatment when the Arbitrator decided, partway through a hearing, to switch from an oral to written hearing format and refused to consider the applicants’ written closing submissions. This case should serve as a reminder that even difficult parties are entitled to procedural fairness.

Ontario – Award set aside where one of three arbitrators biased – #898

Vento Motorcycles, Inc. v The United Mexican States, 2025 ONCA 82 is the second recent Ontario decision (after Aroma Franchise Company, Inc. v. Aroma Espresso Bar Canada Inc., 2024 ONCA 839 on the issue of reasonable apprehension of bias of an arbitrator, which arbitration practitioners have been awaiting. In this decision, there was no challenge to the finding in the Court below that the conduct of one of the arbitrators on a panel of three met the test for reasonable apprehension of bias. The appellant argued that the judge below was wrong to exercise her discretion to not set aside the award. This Court allowed the appeal and set aside the award. It found that it was impossible to determine whether one arbitrator’s bias affected the outcome. Reasonable apprehension of bias on the part of the arbitrator is such a serious breach of procedural fairness that the award must be set aside, even if it requires a re-hearing of the arbitration.

Ontario – Alleged error in applying the law not a jurisdiction issue – #865

In Clayton v. Canada (Attorney General), 2024 ONCA 581, the Court dismissed an appeal from an order dismissing an application to set aside an arbitral award made under Chapter 11 of NAFTA (“the Award”). The appellants sought to set aside the award on the grounds that the tribunal exceeded its jurisdiction and that the award violated public policy. The Court rejected both arguments. In the underlying arbitration, which was bifurcated into liability and damages hearings, the tribunal found that the respondent had breached the relevant NAFTA provisions, but that the appellants did not establish that the breach caused the damages sought. The appellants applied to the Ontario Superior Court to set aside the Award, arguing that the tribunal exceeded its jurisdiction by not properly applying the law, and that the Award violated public policy because it was “so unreasonable as to be unenforceable”. The Superior Court dismissed the application. The Court of Appeal dismissed the appeal. Challenges to arbitral awards on jurisdictional grounds are restricted to “true jurisdictional questions”, and there is a very high burden to set aside an award for public policy reasons.

International – Award set aside after eulogy reveals friendship between tribunal president and counsel – #856

In Port Autonome de Douala v. Douala International Terminal Co. (original French, my translation), the French Court of Cassation (France’s Supreme Court) upheld the Paris Court of Appeal’s decision (original French, my translation) to set aside an arbitral award rendered by a three-arbitrator tribunal based on doubts as to the impartiality of the presiding arbitrator. Those doubts arose from a eulogy he gave of the lead counsel for one of the parties, which revealed that they were close personal friends and that the presiding arbitrator consulted that counsel “before making any important decision”.

B.C. – Insufficiency of Reasons Breached Due Process – #848

In Sound Contracting Ltd. v Campbell River (City), 2024 BCSC 933, the court allowed the set- aside challenge of an arbitral award and remitted the matter to the arbitrator on the basis that the arbitrator had failed in his duty under natural justice to provide adequate reasons. The arbitrator concluded that the arbitration was time-barred but did not explain why he had reached that conclusion. In so doing, the court treated the set-aside challenge as akin to an appeal, where insufficient reasons amount to an error of law. In so doing, the court applied principles in the civil (appeal) and administrative (judicial review) contexts to the set aside of an arbitral award. This stands in contrast to how this issue has been treated internationally, where the matter of whether insufficiency of reasons is a breach of procedural fairness is not well-settled.
