Ontario’s push to expand nuclear energy took another significant step forward as Ontario Power Generation (OPG) signed an agreement with the Municipality of Port Hope to explore the development of a new large-scale nuclear reactor.
Energy Minister Stephen Lecce announced the partnership, calling it a landmark move in strengthening Ontario’s clean energy supply while generating substantial economic benefits. According to Lecce, the proposed project could create approximately 1,700 jobs in the Port Hope area and more than 10,000 jobs across the province during construction and related economic activity.
OPG formally submitted its initial project description to the Impact Assessment Agency of Canada on January 12, marking the beginning of the federal review and approval process. The assessment will evaluate environmental, technical and community considerations before any final construction decisions are made.
If approved, the facility would form part of what the province envisions as the largest nuclear power station in the world. Provincial officials estimate the new reactor could generate enough electricity to power up to 10 million homes, supporting Ontario’s growing energy demands driven by population growth, electrification and expanding industries.
Port Hope Mayor Olena Hankivsky welcomed the agreement, describing it as a strategic opportunity for long-term regional prosperity. She emphasized that collaboration with OPG could position the municipality as a key contributor to Ontario’s clean energy future while stimulating local investment and job creation.
Ontario has increasingly relied on nuclear power as a cornerstone of its energy strategy. The province recently completed a $12.8-billion refurbishment of the Darlington Nuclear Generating Station. In addition, four small modular reactors are currently under development at the same site. Meanwhile, discussions are ongoing regarding a potential new large-scale nuclear plant at Bruce Power in Tiverton.
The Port Hope agreement signals continued provincial commitment to nuclear expansion, as Ontario works to secure reliable, low-emission electricity for decades to come.
