Three proposed interveners (Grand Council of Treaty 3, Justice for Children and Youth, and HIV/AIDS Legal Network/Clinic) sought leave to intervene in a judicial review application challenging the Ontario government's directive to revert to the 2010 elementary school curriculum.
The court granted leave to all three proposed interveners, finding that they each had a substantial and identifiable interest in the subject matter, possessed special expertise, and would provide a useful and distinct contribution to the resolution of the Charter issues raised in the main application without causing injustice or undue delay.
