3 min readSources: Courthouse News

The Supreme Court of Canada heard constitutional challenges to Ontario’s Rebuilding Ontario Place Act immunity provisions.

Why it matters: The ruling will clarify limits on provincial immunity and judicial oversight in urban redevelopment, affecting government accountability and legal counsel advising on such projects.

  • The Supreme Court heard appeals on Ontario’s Rebuilding Ontario Place Act (ROPA) on October 15, 2026.
  • ROPA exempts the redevelopment from environmental, heritage, and municipal noise regulations, granting broad immunity while preserving judicial review rights.
  • Ontario Place Protectors argue ROPA violates Section 96 of the Constitution Act by restricting superior court jurisdiction.
  • Lower courts upheld ROPA in 2024 and 2025, but the Supreme Court granted leave to appeal in January 2026, with a decision pending.

On October 15, 2026, the Supreme Court of Canada heard arguments challenging the constitutionality of Ontario’s Rebuilding Ontario Place Act (ROPA), enacted in 2023 to accelerate redevelopment of the Ontario Place waterfront site in Toronto.

ROPA exempts the project from the Environmental Assessment Act and the Ontario Heritage Act, removes City of Toronto noise regulation authority, and grants the provincial government broad legal immunity from claims related to redevelopment, although it preserves judicial review.

The coalition Ontario Place Protectors contends ROPA infringes on the superior courts’ jurisdiction under Section 96 of the Constitution Act, 1867. Counsel Andrew Lokan characterized ROPA as providing "blanket immunity for a wide range of parties over a potentially wide range of conduct for all time."

The Ontario Superior Court dismissed the challenge in July 2024, and the Ontario Court of Appeal upheld that decision in March 2025, ruling that courts cannot be used as venues for political grievances.

The redevelopment includes multiple components: a private spa, relocating the Ontario Science Centre, new waterfront play areas, additional parking, and a provincial police detachment.

Ontario’s attorney Zachary Green maintained that "ROPA does not make Ontario Place a lawless zone." The Supreme Court granted leave to appeal on January 8, 2026.

The upcoming ruling is poised to define the boundaries of provincial immunity and judicial authority over large-scale redevelopment legislation, impacting counsellors and judiciary who review government urban renewal efforts across Canada.

By the numbers:

  • 2023 — Year Ontario enacted the Rebuilding Ontario Place Act (ROPA)
  • October 15, 2026 — Date Supreme Court heard appeals
  • January 8, 2026 — Supreme Court granted leave to appeal

What's next: The Supreme Court’s decision, expected later in 2026, will clarify judicial oversight and immunity limits in redevelopment laws across Canada.
