Ontario Investing $1 Billion to Build Small Modular Reactors at Darlington

October 23, 2025

Beamsville – As part of its plan to protect Ontario and build a more competitive, resilient and self-reliant economy, the province is investing $1 billion through the Building Ontario Fund in the first Small Modular Reactors in the G7 at the Darlington Nuclear Station in Durham Region. Ontario’s Small Modular Reactors will create 18,000 jobs during construction with 3,700 jobs during operation, while contributing $38.5 billion to Canada’s Gross Domestic Product over the next sixty-five years.

“This historic milestone for power generation in Ontario is part of the largest nuclear expansion in North America,” said Sam Oosterhoff, MPP for Niagara West.

“As Associate Minister of Energy, it was a privilege to stand shoulder-to-shoulder with the Premier at the Darlington Nuclear Station in Bowmanville, today, as our government announced this historic step forward.”

“Today’s investment to support the first Small Modular Reactors in the G7 is a down payment on Ontario’s nuclear energy future,” said Hon. Doug Ford, Premier of Ontario.

“We are protecting Ontario by supporting good-paying, long-term jobs for Ontario workers and building the energy infrastructure – including both Small Modular Reactors and new, large-scale nuclear – needed to make Ontario an energy superpower.”

The province and federal government are making historic investments in this nation-building project, including a $1 billion provincial investment through the Building Ontario Fund and a $2 billion federal investment through the Canada Growth Fund, respectively. Once construction of the four Small Modular Reactors is complete, they will produce 1,200 megawatts of electricity, enough to power the equivalent of 1.2 million homes.

Construction on the first Small Modular Reactor began in May 2025, with the reactor expected to come online in 2030. Today’s funding will support the construction and operation of the first Small Modular Reactor with an innovative model to allow for additional private sector and Indigenous investment.

“As we navigate tariffs and global volatility, it has never been more important to create a more competitive, more resilient and self-reliant province that can withstand whatever comes our way,” said Hon. Peter Bethlenfalvy, Minister of Finance.

“Through the Building Ontario Fund, we are investing in this nation-building project that will secure the clean, reliable energy our growing province needs while creating thousands of good-paying jobs for Ontario workers.”

The first-of-its-kind in the G7, the Small Modular Reactors that make up the Darlington New Nuclear Project will inject $500 million annually into the Canadian supply chain. The construction, operation and maintenance of the four units will add $38.5 billion to Canada’s Gross Domestic Product over the next sixty-five years.

The government has worked with Ontario Power Generation to ensure that eighty percent of project spending goes to Ontario companies, including steel produced in Ontario, by Ontario steelworkers, and that construction and operations will protect workers and jobs by sustaining an estimated 3,700 highly skilled, good-paying jobs annually.

“With rising instability in the global economy, now is exactly the time to be building big, creating thousands of jobs, and investing in the Canadian nuclear supply chain,” said Hon. Stephen Lecce, Minister of Energy and Mines.

“Ontario is leading the largest nuclear expansion on the continent, anchored by the G7’s first Small Modular Reactor being built at Darlington. Our government secured a commitment to keep at least eighty percent of the reactor construction in Ontario – supporting our workers, technology sector and economy.”

In addition to the Darlington New Nuclear Project and refurbishments at the Darlington and Pickering nuclear generating stations and Bruce Power, Ontario is exploring multiple new nuclear energy generation projects to build for the future. This includes the Wesleyville site of Ontario Power Generation in Port Hope, which could host up to 10,000 megawatts of reliable, emissions-free power and conducting pre-development work with Bruce Power to site the first large-scale nuclear build in over three decades with up to 4,800 megawatts of new nuclear generation.
