Executive Summary: Key Legal and Evidentiary Issues

• Jennifer Lamy asked the Quebec Superior Court to suspend her own application for authorization to institute a class action, an unusual procedural posture since it is typically the defendant who seeks a stay.
   
• Nissan Canada Inc. opposed the suspension, arguing that the interests of the proposed Quebec class members favoured allowing the Lamy proceeding to continue.
   
• Determining whether the Lamy and Allard proceedings shared an identity of facts was central to the analysis under article 3137 C.C.Q.
   
• Differences between the scope of the Alberta Allard claim (all Nissan and Infiniti models, a broad paint defect) and the Lamy claim (only the Nissan Kicks, a specific roof-to-windshield defect) were closely examined.
   
• Whether the Quebec class members' interests would be better served by a narrower, targeted proceeding than by a broader multi-territorial one was also at issue.
   
• Timing considerations arose from the fact that neither the Lamy nor the Allard proceeding had yet reached the authorization or certification stage.
   

Facts of the case

Jennifer Lamy filed an application for authorization to institute a class action against Nissan Canada Inc. in the Quebec Superior Court on September 9, 2025, concerning an alleged paint bubbling and rust defect at the roof-to-windshield junction of Nissan Kicks vehicles. This was one of three related proceedings identified by the Court: Durocher v. Nissan, filed in Quebec on July 28, 2025, alleging a general paint problem across various Nissan models; Allard v. Nissan et al., filed in Alberta on August 25, 2025, alleging a widespread paint defect affecting all Nissan and Infiniti models from 2010 onward; and Lamy's own claim. Plaintiffs' counsel in the two Quebec files (Durocher and Lamy) were the same, and they collaborated with Alberta counsel on the Allard file. Counsel for the Quebec plaintiffs had committed to seeking suspension of both Durocher and Lamy in favour of Allard, and the Durocher suspension was granted, unopposed, on July 16, 2026. In the Lamy file, however, Nissan opposed the suspension, arguing that the facts underlying Lamy's claim differed materially from those in Allard and that suspending Lamy was not in the best interests of the Quebec class members.

Policy and legislative provisions at issue

The Court's analysis centered on article 3137 of the Civil Code of Québec, which allows a Quebec authority to stay a proceeding when another action between the same parties, based on the same facts and having the same object, is already pending before a foreign authority capable of producing a decision recognizable in Quebec. Article 577 of the Code of Civil Procedure was also engaged, as it requires the Court, when asked to stay an application for authorization of a class action, to take into account the protection of the rights and interests of Quebec residents, and expressly provides that a court may not refuse to authorize a class action solely because its members are also part of a multi-territorial class action filed outside Quebec. The Court also considered its inherent power to suspend proceedings under articles 18 and 49 C.C.P., independent of whether the formal conditions of article 3137 C.C.Q. are met.

Reasoning and analysis

The Court explained that two avenues exist for suspending a Quebec class action in favour of an out-of-province proceeding: a formal route under article 3137 C.C.Q., requiring identity of parties, facts, and object plus priority in time of the foreign proceeding, subject to judicial discretion even where all conditions are met; and a more flexible route grounded in the Superior Court's inherent jurisdiction, focused on the interests of the proposed class members and the sound administration of justice. Applying these principles, the Court found that although Nissan conceded identity of parties and object, and that Allard preceded Lamy in time, there was no identity of facts. The Court compared the pleadings in detail: Allard alleged a broad, widespread paint defect across all Nissan and Infiniti models tied to a factory coating or painting-process defect, while Lamy alleged a narrower, specific defect confined to the Nissan Kicks roof-to-windshield area, attributed to a windshield design defect rather than a painting-process failure. The Court noted that plaintiffs' counsel had deliberately chosen to bring Lamy as a separate claim rather than folding it into Durocher, which undercut the argument that the claims were factually identical. Turning to the interests of the class members, the Court found that Quebec members were better served by a targeted claim addressing the specific defect alleged in Lamy than by the much broader Allard proceeding, which did not reference the defect at issue in Lamy. The Court also observed that both proceedings were at the same early stage, with neither authorized nor certified, and relied on the Court of Appeal's guidance in Hazan that a suspension request made before the competing proceeding has been authorized or certified may properly be dismissed as premature.

Ruling and overall outcome

The Court dismissed Lamy's application to suspend her own application for authorization to institute a class action and to act as representative, finding that there was no identity of facts between the Lamy and Allard proceedings and that suspension would not serve the interests of the proposed Quebec class members at this stage. Nissan, which had opposed the suspension, therefore prevailed. Costs were ordered to follow, with no specific quantum determined in the judgment.
