List of generating stations in Ontario

This is a list of electrical generating stations in Ontario, Canada.

Nuclear

Nuclear power accounts for roughly 60% of Ontario's power generation, and represents the baseload of its power supply. The government plans to maintain nuclear power's role in energy generation through to 2025. Ontario currently has 18 nuclear units in operation. These reactors amount to 11,400 MW of generation capacity and are located at three sites. The stations were constructed by the provincial Crown corporation, Ontario Hydro. In April 1999 Ontario Hydro was split into five component Crown corporations with Power Generation taking over all electrical generating stations.
