First Nations launch legal challenge against Ontario, federal bills 5 and C-5
ONTARIO, CANADA, JUL 14 – Nine Ontario First Nations argue Bills 5 and C-5 threaten Indigenous self-determination and environmental protection by fast-tracking infrastructure projects without proper consultation, seeking a court injunction.
- On July 15, 2025, nine First Nations from Ontario initiated a legal challenge against both federal Bill C-5 and provincial Bill 5 by filing their case at the Ontario Superior Court.
- The litigation arises from concerns that these laws fast-track major projects like mines and pipelines without proper Indigenous consultation, threatening First Nations' rights and self-determination.
- The laws allow governments to approve projects considered in the national interest quickly and to suspend municipal and provincial laws by creating special economic zones, notably in the Ring of Fire mineral-rich area.
- Chief Sylvia Koostachin-Metatawabin expressed concern that proceeding rapidly with large projects without fully understanding their impacts risks harming their lands and future generations, while Chief Todd Cornelius emphasized the importance of careful and responsible decision-making rather than rushing through development.
- The First Nations are requesting a court order to prevent the federal government from designating projects as being of national interest and to block Ontario from establishing special economic zones, arguing that these laws infringe upon constitutional rights.
