Nuclear safety oversight
OPG’s nuclear safety regulator is the Canadian Nuclear Safety Commission (CNSC).
Under the Nuclear Safety and Control Act (NSCA), the CNSC is responsible for:
- Regulating all nuclear facilities and nuclear-related activities in Canada, and
- Granting station operating licences, which set out the regulations and requirements that stations must operate under.
Oversight of OPG
The CNSC has a presence at each nuclear station in Canada, with continuous access to inspect our stations and review our activities and report to the CNSC Tribunal, an appointed body of individuals who provide further oversight on nuclear activities.
OPG must notify the CNSC of activities which meet the criteria for 'Event Reports', provided to CNSC staff when an activity meets the thresholds set out by the Commission’s regulation document 3.1.1, available below.
Event Reports number fewer than 100 per year, but receive intense scrutiny for causes, corrective action and resolution.
A handful of ‘Event Reports’ may warrant further review by the CNSC Tribunal at one of their regularly held public meetings, where root cause, remedial actions and resolution are discussed in a public forum.
