News release
Today, the Canadian Nuclear Safety Commission (CNSC) announced the independent Commission’s decision to amend the licence held by Ontario Power Generation Inc. (OPG) for the Pickering Nuclear Generating Station (PNGS). This decision authorizes OPG to operate Units 5–8 at the PNGS until December 31, 2026, up to a maximum of 305,000 equivalent full power hours (EFPH).
The PNGS site is located in Pickering, Ontario, on the traditional lands and waters of the Michi Saagiig Anishinaabeg, the Gunshot Treaty (1877–88), the Williams Treaties (1923), and the Williams Treaties Settlement Agreement (2018).
OPG was previously authorized to operate Units 5–8 at the PNGS until December 31, 2024, up to a maximum of 295,000 EFPH. The amended licence includes a new condition requiring OPG to implement and maintain an enhanced fitness-for-service program.
In making its decision, the Commission considered submissions from OPG, CNSC staff and 54 intervenors during a public hearing in Pickering in June 2024. All submissions are available on the CNSC website.
A summary record of decision is available upon request to the Commission Registry. The detailed reasons for the Commission’s decision, including the Commission’s assessment of all submissions made in relation to the application, will be provided in a detailed record of decision at a later date. Both documents will also be posted in both official languages on the CNSC website.
