Ontario Advances Bruce C Nuclear Project with $300M Pre-Development Agreement

Ontario Advances Bruce C Nuclear Project with $300M Pre-Development Agreement Aaron Larson Thu, May 7, 2026 at 11:09 PM GMT+7 10 min read Ontario took its most decisive step yet toward building Canada’s first large-scale nuclear station in more than three decades, directing the Independent Electricity System Operator (IESO) to enter a cost-sharing and recovery agreement with Bruce Power to advance pre-construction work on the proposed Bruce C project. The agreement, announced on May 7 by Energy and Mines Minister Stephen Lecce, unlocks roughly $300 million for First Nations and community engagement, workforce planning, site preparation, and pre-construction activities scheduled to be completed by 2030. If the full project proceeds through federal regulatory approvals, Bruce C would add up to 4,800 MW of new nuclear generating capacity at the existing Bruce site on Lake Huron. Provincial figures cited in the announcement project a $238 billion contribution to Canada’s gross domestic product (GDP), 18,900 jobs during construction, and 6,700 permanent jobs once the station is operational. The Ontario Chamber of Commerce, in a recent report, estimated the project would funnel an annual average of $2 billion in local GDP, $427 million in labor income, and 3,400 full-time jobs to surrounding Bruce, Grey, and Huron county communities. “At a time when our economy faces threats from abroad, Ontario’s government is doubling down on made-in-Canada nuclear power,” Lecce said in a statement, framing Bruce C as the centerpiece of a continent-leading nuclear expansion that he said could ultimately put 150,000 Canadians to work. He added that the project is intended to “transform Bruce Power into the world’s largest nuclear generating facility.”

The May 7 announcement is the most consequential follow-through on a process that began in July 2023, when the province first directed Bruce Power to launch community consultations and a federal environmental assessment to evaluate the feasibility of siting up to 4,800 MW of new nuclear generation at the existing Bruce site. That earlier announcement, made under former Energy Minister Todd Smith, framed pre-development work as a precaution against electricity demand that—for the first time since 2005—was beginning to climb. In 2024, Bruce Power formally launched the federal Impact Assessment process by submitting an Initial Project Description to the Impact Assessment Agency of Canada. That assessment, the first in a multi-year approval pathway for new large-scale nuclear projects, is expected to be completed in 2028. A Licence to Prepare Site from the Canadian Nuclear Safety Commission (CNSC) will follow. The May 7 cost-sharing direction sits alongside a 2024 Minister’s Directive that established the original IESO–Bruce Power funding arrangement for the federal Impact Assessment work. Together, the agreements give Bruce Power a clearer financial runway to advance engineering studies, vendor qualification, supply-chain readiness, and labor planning before any final investment decision.

The Bruce C decision is being driven by a transformed forecast for Ontario electricity demand. The province’s announcement points to growth of “up to 90 per cent by 2050”—a figure that reflects more aggressive electrification scenarios than the IESO’s 2025 Annual Planning Outlook (APO) reference case, which models a 75% increase in electricity demand over the same period. Whichever curve the system ultimately follows, planners agree that significant new generation will be required. By 2034, the IESO’s APO sees emerging energy and capacity gaps reaching roughly 2,100 MW of capacity and 7 TWh of energy. The IESO and Ontario’s nuclear operators have concluded that delivering up to 17,800 MW of new nuclear capacity by 2050—equivalent to about five Darlington-sized stations—is technically feasible, and would require building at least eight large units beyond what is already planned at Bruce C, plus potentially extending the life of Bruce Units 1 and 2 through a second refurbishment. Drivers of demand growth are diversifying. Transportation electrification is forecast to be the largest single contributor, with electric vehicle (EV)–related electricity demand reaching 20 TWh by 2035. Industrial demand is expected to rise 58% by 2035 as automotive, EV battery, advanced manufacturing, and critical-mineral mining investments flow into the province. Data centers serving artificial intelligence (AI) and cloud workloads are projected to account for roughly 13% of new electricity demand by 2035.
