First Nations Groups File Legal Challenge to Ontario’s Bill 5, Feds’ Bill C-5: A coalition of Ontario First Nations is taking legal action to try and throw out provincial and federal legislation designed to fast-track major projects, saying the two laws threaten their rights and “ways of life.” Nine First Nation groups are bringing urgent litigation to the Ontario Superior Court of Justice to try and kill Ontario’s Bill 5 and the federal government’s Bill C-5. The Ford government passed Bill 5 in June, which allows it to create special economic zones where municipal and provincial laws can be suspended. Similarly, the federal Bill C-5 allows cabinet to quickly grant federal approvals for big projects deemed to be in the national interest, such as mines, ports and pipelines, by sidestepping existing laws.

In Hayes v. The City of Saint John, 2025 NBKB 58, the New Brunswick Court of King's Bench held that the vulnerable nature of the class in a historical sexual abuse class action demanded that the individual issues phase of the litigation be dealt with on an expeditious basis.

Cline v Gymnastics Canada, 2025 BCSC 146 is a pre-certification jurisdictional application brought by the Fédération de Gymnastique du Québec in a proposed historical abuse class action commenced in B.C.

The court found the Parkin action was superior to two competing actions as it avoided both potential concerns relating to contingency-fee splitting with a US firm and limitation period issues.
