Animal Justice is intervening in an important Supreme Court of Canada case today about Toronto’s Ontario Place redevelopment. This landmark appeal could decide whether governments can shield themselves from legal accountability for harming animals and wildlife habitats.
Since 1971, Ontario Place, which sits on human-made islands, has evolved into a thriving green space. This urban haven provides essential habitat for local wildlife and acts as a critical flyover zone for migratory birds.
Why Development Threatens Ontario Place Wildlife
The Ontario government recently approved a massive redevelopment project on the site featuring a sprawling glass spa complex. Construction workers have already bulldozed roughly 850 trees, destroying animal habitats and putting local minks, beavers, and migratory birds at risk.
Furthermore, experts warn that the proposed glass structures could be disastrous for migratory birds navigating the lakefront corridor, including Yellow Warblers, American Robins, Chimney Swifts, and Eastern Wood-Pewees. Advocates also fear the loss of crucial nesting sites for the Barn Swallow, a species designated as being of “special concern” under Ontario’s Endangered Species Act.
To block potential lawsuits over environmental damage, the province passed the Rebuilding Ontario Place Act in 2023. This law removes nearly every legal path for the public to challenge the government in court. After the Ontario Court of Appeal upheld the law, a local group called Ontario Place Protectors has taken the fight to the Supreme Court of Canada.

Animal Justice Fights for Absolute Legal Accountability
Animal Justice is arguing that the government cannot give itself total immunity from lawsuits. In this Ontario Place court case, our legal team from Circle Barristers will highlight two important factors:
- Asymmetry: The law creates an unfair situation. The province can sue private citizens, but citizens cannot sue the government back.
- Breadth: The law wipes out an incredibly wide range of legal remedies. It strips away the exact tools that courts need to stop harmful construction.
Animals cannot fight governments themselves. Law is one of the few tools that can be used for humans to protect them.
The Supreme Court’s decision in this appeal will have significant implications for governments’ ability to permit large-scale harm to wildlife with total immunity.

The Ontario Place Court Case Has National Implications
This case is not solely a local Toronto dispute about development. It is an appeal with significant national implications for the rule of law. Animal Justice regularly brings court cases to challenge decisions that harm animals. Our work relies entirely on the principle that the government must follow the law.
We have a long history of fighting before Canada’s highest courts. For instance, we intervened in R v DLW and Council of Canadians with Disabilities v British Columbia.
