Supreme Court hears challenge of law clearing path for Ontario Place redevelopment

The Supreme Court of Canada is set to hear a challenge on Thursday from a group opposing the constitutionality of legislation that allows for major changes at Ontario Place, a Toronto waterfront park established in 1971. The theme park, once featuring attractions like a spherical theatre, play areas and a revolving concert stage, is now proposed to be redeveloped into a spa operated by a private company, a relocated Ontario Science Centre and other enhancements.

The provincial government's Rebuilding Ontario Place Act aims to facilitate these changes, but a coalition known as Ontario Place Protectors argues that the legislation undermines court scrutiny of state actions, thus breaching the Constitution. They contend that the act removes essential court powers and violates the doctrine of public trust, which safeguards natural and cultural assets.

Despite an unsuccessful appeal in 2024 and a subsequent Court of Appeal dismissal, the coalition persisted, arguing that the provincial courts have the authority to review laws and government actions protected under the Constitution Act. The court will decide whether the act's provisions violate the law or the Constitution.
