The Wesleyville site was supposed to host an oil-fired power station in the 1970s, but although the plant was built, it never became operational. OPG has maintained the property, which is located near existing transmission, road, and railway infrastructure and is already zoned for new electricity generation.

Stephen Lecce, Ontario’s Minister of Energy and Mines, said that the site has the potential to generate up to 10 GW. The Wesleyville nuclear project is expected to support over 10 000 jobs in Ontario, and will contribute around C$235 billion (€160 billion) to Ontario’s GDP over the power plant’s projected 78-year lifespan.
