Pickering Nuclear Generating Station is a Canadian nuclear power station located on the north shore of Lake Ontario in Pickering, Ontario. It is one of the oldest nuclear power stations in the world and Canada's third-largest, with eight CANDU reactors. Since 2003, two of these units have been defuelled and deactivated, with two additional units being taken offline as of 2025. The remaining four produce about 11% of Ontario's power and employ 3,000 workers.
A single 1.8 MWe wind turbine, named the OPG 7 commemorative turbine, was installed on the site of the generating station until October 2019, when it was dismantled.
