Ontario Power Generation (OPG), a successor company of the former Ontario Hydro, is 100% owned by the Province of Ontario. OPG currently operates Darlington, Pickering A and Pickering B nuclear generating stations.

Pickering A station went into service in 1971 and continued to operate safely until 1997 when it was placed in voluntary lay-up as part of OPG's nuclear improvement program. OPG's Pickering A Restart Project to return the units to service starting in 2003, received approval from the Canadian Nuclear Safety Commission. Pickering 4 was declared back in service on September 25, 2003 and Pickering 1 went commercial November 3, 2005. Pickering B and Darlington stations are operational.

OPG also operated Bruce A and Bruce B nuclear generating stations until May 2001 when they were leased to Bruce Power L.P.

Nuclear power stations currently provide about 38% of electricity generated by OPG. Darlington Nuclear Generating Station alone is capable of providing about 20 per cent of Ontario's electricity needs.
