Press Release
January 12, 2026
Ontario Power Generation Inc. is proposing the construction of a new nuclear power plant in the Municipality of Port Hope, Ontario. As proposed, the New Nuclear at Wesleyville Project (the project) would provide up to 10,000 megawatts of new nuclear generating capacity and operate for at least 60 years. Several nuclear reactor technologies will be considered for the project.
This project is anticipated to be subject to an integrated assessment to meet the requirements of the Impact Assessment Act and the Nuclear Safety and Control Act. The Impact Assessment Agency of Canada (IAAC) and the Canadian Nuclear Safety Commission (CNSC) are working together on the integrated assessment to achieve the goal of “one project, one review”.
