Ontario Power Generation (OPG) owns and is licensed to operate the Pickering Nuclear Generating Stations.

Nuclear power plants

Pickering A began operating in 1971 and consists of four nuclear power reactors licensed to produce 500 megawatts of electricity each. Of these reactors, units 1 and 4 are operating while units 2 and 3 are in an approved shutdown state.

Pickering B started up in 1982 and is also comprised of four nuclear power reactors licensed to produce 500 megawatts of electricity each. All four reactors at Pickering B are currently operating.

Waste management facility

The Pickering Waste Management Facility is located on the same site as the generating stations and stores spent fuel from the power reactors, along with intermediate- and low-level radioactive wastes.

The Canadian Nuclear Safety Commission (CNSC) has full-time employees who work on site at the Pickering A and B facilities to perform inspections, evaluate operations, and verify compliance with regulatory requirements and licence conditions. Other CNSC employees periodically visit to carry out regulatory activities.

Located approximately 45 km east of the Pickering facilities is the Darlington nuclear power plant in Bowmanville, Ontario.
