How we selected the site

Canada’s plan for used nuclear fuel is moving forward in an area with informed and willing hosts.
Canada’s deep geological repository for used nuclear fuel will be located at the Revell Batholith, a rock formation in northwestern Ontario.

The Revell site was selected after extensive technical studies and a willingness process where the potential host communities — Wabigoon Lake Ojibway Nation and the Township of Ignace — agreed to support advancing the project into the regulatory decision-making phase.

About the site selection process

The process to select a site for Canada’s plan to safely manage used nuclear fuel over the long term started in 2010.

By 2012, 22 communities had proactively expressed interest in learning about the project and exploring their potential to host it.

22 communities 

The site selection process emerged through a two-year dialogue. It reflected the ideas, experience and best advice of a broad cross-section of Canadians who shared their thoughts on what an open, transparent, fair and inclusive process for making this decision should include. It was built on a set of guiding principles and was developed within our ethical and social framework.

The site selection process was designed to ensure:

  • The selected site is safe and secure.
  • It has informed and willing hosts.
  • It meets the highest scientific, professional and ethical standards.

Together with communities, we assessed potential sites’ ability to meet the project’s robust safety requirements, the possibility of developing a safe and socially acceptable plan to transport the used nuclear fuel to the site, and the potential to build supportive and resilient partnerships.

In 2024, Wabigoon Lake Ojibway Nation and the Township of Ignace confirmed they would support advancing the project into the regulatory decision-making phase.

Each of the communities developed their own processes for defining willingness and determining how they would express it.

Canada’s deep geological repository project for used nuclear fuel is now moving through the regulatory decision-making process.

Site requirements

The safety and appropriateness of the site is assessed against a number of factors, both technical and social in nature.

Confidence in safety

Our Confidence in Safety report summarizes our understanding of the siting area. Based on years of research and field work, it concludes that the site can meet the project's requirements to contain and isolate used nuclear fuel in a way that will protect people and the environment.

Indigenous Knowledge

We continuously seek to align with the Indigenous Knowledge shared with us by Knowledge Holders working with the NWMO and those from the host communities.


As we continue to move through the regulatory decision-making process and engage with communities, there is an opportunity to learn from local Indigenous Knowledge and apply that learning.
