Impact Assessment Agency of Canada Releases Summary of Issues on Environmental, Social, and Indigenous Impacts of Canada’s Revell DGR Project
On February 16, 2026, the Impact Assessment Agency of Canada (IAAC), working alongside the Canadian Nuclear Safety Commission (CNSC), published the Summary of Issues for the proposed Deep Geological Repository (DGR) for Canada’s Used Nuclear Fuel Project, managed by the Nuclear Waste Management Organization (NWMO).
The release consolidates input from federal and provincial regulators, Indigenous Nations and organizations, and members of the public who provided comments on the Initial Project Description. It provides a comprehensive assessment of potential environmental, social, and economic effects associated with one of Canada’s largest, multi-generational infrastructure projects. The document is available to the public for review at IAAC’s project registry, and examining it is crucial for anyone wishing to understand or participate in the impact assessment process.
The DGR represents an unprecedented long-term project, with construction, operation, and monitoring phases projected to span nearly 200 years. The Summary of Issues highlights critical questions regarding the long-term containment of radioactive materials, including whether the host rock is suitable, potential seismic or geochemical hazards, and other geological considerations. Submissions from nearby communities emphasize concerns about the effects of radiological exposure on water resources, wildlife, and public health, alongside the challenges of managing cumulative environmental pressures from existing industrial activity. The report stresses the importance of continuous monitoring, accountability, and robust institutional controls to ensure safety for generations to come.
Transporting used nuclear fuel to the DGR also surfaced as a major area of concern. Indigenous Nations and communities along potential transportation routes highlighted risks of accidents, infrastructure strain, and emergency response challenges, as well as possible socio-economic disruptions. The IAAC document underlines the need to meaningfully integrate Indigenous Knowledge, community consultation, and local input throughout planning and operations, ensuring that traditional land uses and cultural practices are respected and considered in decision-making.
Health, social, and economic implications feature prominently in the Summary of Issues. Public submissions noted potential impacts from the temporary workforce, pressures on housing and local services, and questions about equitable distribution of project benefits. Concerns about short-term employment spikes, property values, and long-term economic stability illustrate the complexity of managing a multi-generational project in close-knit and Indigenous communities.
For residents living near the Revell site, particularly in Borups Corners and Dyment, the Summary of Issues is highly relevant. Our Melgund Integrated Nuclear Impact Assessment (MINIA) Project focuses specifically on these communities, combining environmental, social, and cultural research to provide detailed local insights. Engaging with IAAC’s review process and submitting comments ensures that local perspectives, alongside broader federal and Indigenous input, are considered in shaping responsible, long-term decisions for the DGR.
Reviewing the Summary of Issues and participating in the consultation process is essential for anyone concerned about Northwestern Ontario’s environmental, social, and economic future. Public engagement enables Canadians to help guide how the DGR addresses long-term safety, radioactive containment, Indigenous rights, and community well-being.
