Ontario's Bruce C Project: What Canada's Largest Nuclear Expansion Means

May 7th, 2026

Ontario took a landmark step forward in May 2026, directing the Independent Electricity System Operator to enter into a cost-sharing agreement with Bruce Power to advance pre-development work on the Bruce C Project — Canada's first large-scale nuclear build in over 30 years.

The proposed facility would add up to 4,800 megawatts of nuclear capacity which is enough to power 4.8 million homes, inject $238 billion into Canada's GDP, and create 18,900 jobs during construction and 6,700 once operational. The $300 million in pre-development funding will support technology selection, workforce and commercial planning, site preparation, cooling water strategy development, and ongoing Indigenous and community engagement through 2030.

The Bruce C announcement is the latest in a series of signals that Canada is making nuclear a cornerstone of its energy and economic strategy. This initiative reflects a national consensus that clean, reliable, sovereign power is not a long-term aspiration but an immediate priority.

For CSMC, this momentum is the backdrop against which the LEUNR program is advancing. The same national urgency driving billion-dollar investments in large-scale nuclear is precisely what portable micro-nuclear technology is designed to address in the places large-scale infrastructure cannot reach: remote communities, northern military installations, and eventually, the lunar surface. Canada's nuclear ambitions are scaling at every level, and CSMC is building for the frontier.
