Peter Douglas authored a blog examining the British Columbia Supreme Court’s decision in MacKinnon v Pfizer Canada Inc, which highlights the challenges of certifying national class actions based solely on provincial consumer protection legislation. The decision underscores the significant differences among provincial consumer protection regimes and reinforces the difficulty of advancing national class proceedings without relying on additional causes of action such as negligence, breach of contract, or Competition Act claims.

Peter Douglas explores evolving approaches to managing multijurisdictional class actions in Canada in the blog he co-authored, Discontinuance of a Class Action: A New Approach to Multijurisdictional National Settlements in Québec. The blog examines the Québec Superior Court’s decision in Bourgeois v Electronics Arts Inc and how it signals a willingness by Québec courts to defer to settlements approved in other provinces where the rights of Québec class members are adequately protected, potentially paving the way for a more streamlined single-jurisdiction settlement approval process for national class actions.

Peter Douglas co-authored a blog examining how recent amendments to Ontario’s Class Proceedings Act, 1992 are reshaping the class action landscape by introducing stricter certification requirements and accelerated procedural timelines. It highlights early judicial interpretations of the amendments, including decisions that expand defendants’ ability to bring pre-certification motions and require dismissal of delayed proceedings, signaling a more defendant-friendly approach in Ontario compared to other jurisdictions.
