Grassy Narrows First Nation files legal application to challenge Ontario's Mining Act, arguing free-entry mining system violates their constitutional rights.

Grassy Narrows First Nation in Ontario has filed a legal application to challenge the province's Mining Act, arguing that the free-entry mining system violates their constitutional rights. The First Nation is asking the court to declare that Ontario has a duty to consult and obtain consent before registering or renewing mining claims on their traditional lands. This legal action could potentially invalidate all mining claims in the province if successful, causing significant disruption to the mining industry.
