Should Ontario Build a Major New Nuclear Plant at Wesleyville?

Official title: New Nuclear at Wesleyville Project

Open Environmental Assessment Environment & Climate Indigenous & Northern Natural Resources
Ontario Power Generation wants to build a massive new nuclear power plant near Port Hope. We're talking up to 10,000 megawatts of capacity—enough to power millions of homes—operating for 78 years. The site is on Williams Treaties First Nations territory. Right now, the government wants your input on the initial project description before the full environmental assessment begins.

Why This Matters

This would be one of Canada's largest nuclear projects ever. Live in southern Ontario? This could affect your electricity bills and grid reliability for decades. Concerned about climate change? Nuclear is low-carbon, but comes with waste and safety questions. Indigenous communities have treaty rights in this area that must be respected.

What Could Change

If approved, Ontario would get a new nuclear facility producing up to 10,000 MW for 78 years. The reactor technology hasn't been chosen yet—several options are being considered. Construction would require federal environmental approval and nuclear safety licensing. This early phase shapes what issues the full assessment must address.

Key Issues

  • What environmental and community concerns should the full assessment address?
  • How will Indigenous rights and treaty obligations be respected?
  • What are the potential impacts of operating a nuclear plant for 78 years?
