The recent decisions rendered on the cases Ann Sophie has litigated are as follows:

Canadian Union of Public Employees, Local 4628 v Santé Québec – Centre intégré universitaire de Santé et de services sociaux du Centre-Sud-de‑l’Ile-de-Montréal, 2025 CanLII 135855 (QC SAT): The arbitrator ruled in favor of the employer, stating that the concept of ​“place” for the purpose of granting overtime means ​‘service’ and not ​“facility.” The union’s grievance was therefore dismissed. The union is currently seeking a review of this decision.


Syndicat des employées et employés professionnels-les et de bureau, section locale 573 – CTC-FTQ (SEPB) v Commission de la construction du Québec, 2025 CanLII 138822 (QC SAT): The arbitrator granted the employer’s motion to dismiss after six days of evidence presented by the union, on the grounds that the union had not met its burden of proof. The union’s request for a re-evaluation of the position in question was therefore dismissed.


Société des Casinos du Québec inc. v. Syndicat des croupiers du casino du Lac-Leamy – section locale 3993 du SCFP, 2025 CanLII 142426 (QC SAT): The arbitrator upheld the employer’s defense of estoppel in a dispute over disability insurance. Although the employer’s conduct over the years was contrary to a clause in the collective agreement, the union led the employer to believe that it would not contest it. The grievance is dismissed.

Alliance du personnel professionnel et technique de la santé et des services sociaux v. Santé Québec, 2025 QCTAT 3897 (CanLII): The TAT grants the motion to intervene filed by the CPNSSS in this case, represented by Loranger Marcoux.

Syndicat canadien de la fonction publique, section locale 3333 v. Réseau de transport de Longueuil 2024 QCCA 204: The Court of Appeal clarifies the law and dispels any ambiguity as to whether family or parental status is protected by section 10 of the Charter of Human Rights and Freedoms. It should be noted that the Syndicat has requested permission from the Supreme Court of Canada to hear the case. We are awaiting the Court’s decision.

Leroux v. Société des Casinos du Québec inc./ Casino de Montréal, 2024 QCTAT 2086 (CanLII) : The Tribunal rejected the complainant’s claim that he had been the victim of constructive dismissal. Rather, it was the complainant who decided to retire, without being forced to do so by the employer.

Dextraze v. Société des casinos du Québec inc, 2024 QCTAT 367 (CanLII), motion for internal review dismissed: An investigations supervisor was dismissed for, among other things, intimidating, by e‑mail, an employee who was gradually returning from a disability leave. The Tribunal upheld the dismissal, notably because of the seriousness of the misconduct, but also because of the complainant’s lack of credibility.

Société des casinos du Québec v. Syndicat des croupiers du Casino du Lac Leamy section locale 3993 (SCFP), 2024 CanLII 35768 (QC SAT): A female croupier was dismissed for attempting to appropriate a customer’s purse during a Christmas party organized by the employer. The dismissal was upheld. In particular, the complainant’s defence that she had ​“mistaken” the satchel because of her advanced level of intoxication was not credible.
