OTTAWA — The Supreme Court of Canada has reserved judgment after hearing Ontario Place Protectors' appeal over legislation governing redevelopment of the Toronto waterfront site.

The court's docket records the hearing and reserved decision on Thursday, October 15. No final ruling on the appeal is recorded.

The challenge concerns the Rebuilding Ontario Place Act, 2023, including limits on legal claims against the Crown and exemptions from environmental, heritage and municipal noise rules.

According to the court's case summary, Ontario Place Protectors argues that the legislation interferes with superior courts' constitutionally protected jurisdiction and breaches public trust. These are the group's arguments, not findings by the Supreme Court.

The same summary notes an important distinction: the law preserves applications for judicial review, despite extinguishing certain causes of action and remedies.

Ontario Place Protectors lost in Superior Court in July 2024 and in the Ontario Court of Appeal in March 2025.
