Ontario and Canada Sign Historic Cooperation Agreement to Eliminate Federal Duplication and Unlock the Ring of Fire

December 18, 2025

New ‘One Project, One Process, One Decision’ model will remove duplication, attract investment and get shovels in the ground years faster

Ontario and Canada have signed a historic cooperation agreement that will significantly streamline environmental approvals for major infrastructure and resource projects through a new ‘one project, one process, one decision’ model that is now in effect. The agreement will remove duplicative and overlapping federal impact assessments from Ontario’s world-leading environmental assessment process to build infrastructure faster and unlock resource development across the province, helping to build a more competitive, resilient and self-reliant Canadian economy.

“With this historic agreement, our two governments are working together to protect Ontario and Canada by removing the unnecessary red tape and regulatory duplication that has stood in the way of nation-building projects for too long,” said Premier Doug Ford. “I want to thank Prime Minister Carney for his leadership in speeding up major projects that will create good-paying jobs, build a more competitive and self-reliant economy and help us unlock the enormous economic opportunity of the Ring of Fire.”

Under the ‘one project, one process, one decision’ model, a project that would have previously been subject to both a federal impact assessment and a provincial environmental assessment will now only be subject to Ontario’s environmental assessment process. Doing so will streamline regulatory processes, shorten review timelines, bring certainty to project proponents and help to attract more investment into Ontario’s economy. Today’s agreement also includes a side letter between both levels of government where the Impact Assessment Agency of Canada commits to completing its review of the assessment of the roads to the Ring of Fire no later than June 2026.

“Canada’s new government is focused on what we can control — building a stronger, more sustainable, more independent Canadian economy,” said Mark Carney, Prime Minister of Canada. “Our agreement with Ontario will build major projects faster, helping to diversify our trade partners, strengthen our industries and empower more Canadians with high-paying careers. We are building Canada Strong, and we’re building bigger and faster together.”

Unlocking Ontario’s vast critical mineral resources is an important part of the government’s plan to protect Ontario and build a more competitive, resilient and self-reliant economy. As the global demand for critical minerals needed to manufacture electric vehicles, batteries, modern defence technologies and advanced manufacturing continues to grow, Ontario has the deposits, skilled workforce, expertise and business-friendly investment climate to secure the province’s place as the most competitive jurisdiction in the G7 to invest, create jobs and do business.

“Now more than ever, we need to speed up project timelines and provide greater certainty to businesses and communities looking to build and invest,” said Todd McCarthy, Minister of the Environment, Conservation and Parks. “Together with the federal government, we’re taking decisive steps to build a stronger, more competitive and prosperous economy that creates jobs and prosperity for the people of Ontario, while maintaining environmental protections.”
