Today, the Canadian Nuclear Safety Commission announced the independent Commission’s decision to renew Ontario Power Generation Inc.’s power reactor operating licence for its Darlington Nuclear Generating Station for a period of 20 years.

Today, the Canadian Nuclear Safety Commission (CNSC) announced the independent Commission’s decision to renew Ontario Power Generation Inc.’s (OPG’s) power reactor operating licence for its Darlington Nuclear Generating Station for a period of 20 years. The Darlington facility is located in the Municipality of Clarington, Ontario, on the traditional lands and waters of the Michi Saagiig Anishinaabeg, the Gunshot Treaty (1787–88), the Williams Treaties (1923), and the Williams Treaties Settlement Agreement (2018).

In making its decision, the Commission considered submissions from OPG, CNSC staff and 79 intervenors during a 2-part public hearing. The Commission concluded that OPG remains qualified to carry on the activities that the renewed licence will authorize. There are no changes to OPG’s licensed activities under the renewed licence. 

The decision includes a requirement for OPG to provide 2 comprehensive performance updates to the Commission on the conduct of its licensed activities. It also includes a new licence condition that requires OPG to continue its engagement with Indigenous Nations and communities throughout the licence period.

The record of decision is available upon request to the Commission Registry at [email protected]. The decision will also be posted in both official languages on the CNSC website at cnsc-ccsn.gc.ca at a later date. All submissions related to this licence renewal are available on the CNSC website.
