Class Actions Landscape In Canada: 2025 Mid-year Update

Class actions continue to shape the Canadian legal landscape. As we head toward the end of 2025, we note the following developments emerging from the class actions landscape across Canada so far this year¹.

Class actions filed by jurisdiction

No fewer than 164 proposed class actions were filed in the leading jurisdictions. Québec led the way with 78 authorization applications—more than double Ontario's count and significantly ahead of British Columbia. The disparity underscores Québec's continued prominence as a jurisdiction of choice for initiating class proceedings, likely reflecting its procedural accessibility. Ontario and British Columbia followed with 38 and 48 applications respectively, suggesting a steady but comparatively moderate pace of filings.
