Canada’s plan for a deep geological repository for used nuclear fuel has moved into a multi-year federal regulatory process after the Nuclear Waste Management Organisation (NWMO) confirmed the selection of the Revell area in northwestern Ontario and said the host communities of Ignace and Wabigoon Lake Ojibway Nation had demonstrated willingness to proceed.

The NWMO said the Revell siting decision, taken in November 2024, followed technical studies and community engagement carried out over more than a decade. The Revell area lies within the 2.7-billion-year-old Revell batholith, a crystalline rock formation where boreholes to about 1 km indicate the geological stability and depth required for a repository.
