The Canadian Civil Liberties Association (CCLA) brought a motion for leave to intervene as a friend of the court in an appeal from an order certifying a class action against Ontario.
The underlying class action alleges negligence and Charter breaches in the provision of services to adults with developmental disabilities.
On appeal, Ontario argues that the recently enacted Crown Liability and Proceedings Act, 2019 provides immunity from the negligence claims.
The CCLA sought to intervene to argue that Ontario's expansive interpretation of the Act's immunity provisions violates section 96 of the Constitution Act, 1867.
The court granted the motion, finding that the CCLA would make a useful and distinct contribution to a matter of public importance without causing injustice or undue delay to the parties.
