Regulatory process

The Deep Geological Repository for Canada’s Used Nuclear Fuel Project has entered the regulatory decision-making process. This marks the beginning of a new chapter in Canada’s plan for the safe, long-term management of used nuclear fuel.
Canada’s Deep Geological Repository for Used Nuclear Fuel Project must meet strict regulatory requirements to protect the health, safety and security of people and the environment.

Impact assessment process

Following the announcement of a site in November 2024 in the Wabigoon Lake Ojibway Nation and Ignace area, the project moved towards formally entering the regulatory decision-making process, providing further opportunities for potentially impacted Indigenous groups and the public to share their voice.

The purpose of the regulatory process is for the safety of the repository to be independently confirmed by regulators, including the Canadian Nuclear Safety Commission and the Impact Assessment Agency of Canada. The process follows strict rules and will look at how the deep geological repository could affect the environment, health, socio-economics and Indigenous rights before it can be approved. Engagement and relationship building with Indigenous communities, the public and interested parties remain at the core of the process.

The regulatory process began in January 2026 with the submission and posting of the Initial Project Description on the Impact Assessment Agency of Canada registry.

The NWMO has submitted our Response to the Summary of Issues, which is available now on the Canadian Impact Assessment Registry.

The Summary of Issues, posted by the Impact Assessment Agency of Canada (IAAC), highlights the key themes raised during the 30-day Indigenous and public consultation period on the Initial Project Description. It shows participants how their comments and concerns have been characterized and helps guide the next steps in the regulatory process for the deep geological repository for Canada’s used nuclear fuel.

The NWMO’s Response to the Summary of Issues addresses the consolidated concerns raised by Indigenous Peoples, the public, and government. This submission provides the information requested by the IAAC regarding the Deep Geological Repository (DGR) for Canada’s Used Nuclear Fuel Project.

The NWMO submitted an additional plain language summary document providing consolidated information about the transportation of used nuclear fuel. The document is available here. It outlines how safety is integrated into every aspect of the transportation system, with a strong regulatory framework in place to protect people and the environment.
