OPG applies to Canadian Nuclear Safety Commission for Licence to Construct

On October 31, 2022, OPG completed a significant project milestone by submitting an application for a Licence to Construct to the Canadian Nuclear Safety Commission (CNSC). This licence application is the next step in the deployment of a Small Modular Reactor (SMR) at the Darlington site.

The application was developed collaboratively between OPG and GE Hitachi, and is comprised of a number of information packages that will be submitted to the CNSC in sequence, over the next six months. This licence is required before any nuclear construction work on the SMR at Darlington can begin.

This licence submission comes after another significant milestone, the beginning of site preparation activities earlier in October.

Site preparation work consists of non-nuclear infrastructure activities, such as clearing and grading a portion of the new nuclear site to build roads, utilities and support buildings. Execution of site preparation work is planned to continue into 2025.

How can I participate in the Licence to Construct Application process?

The Licence to Construct process includes opportunities for Indigenous Nations and Communities, and the public, to discuss the application, ask questions and raise areas of interest. The process will culminate in a public hearing, held by the CNSC, likely in 2024.
