PHAI Licence Renewal

Canadian Nuclear Laboratories (CNL) has submitted an application to the Canadian Nuclear Safety Commission (CNSC) for the renewal of the Port Hope Project Waste Nuclear Substance Licence for a term of 10 years.

The current licence expires on December 31, 2022.

As part of the application, CNL is requesting a consolidation of the Port Hope licence and the Port Granby Project Waste Nuclear Substance Licence into a single, ten-year Port Hope Area Initiative (PHAI) licence allowing CNL to:

Continue the cleanup
of historic low-level radioactive waste from various sites in Port Hope for safe, long-term containment and monitoring

Continue maintenance and monitoring
of the capped and closed Port Granby Long-Term Waste Management Facility

Reduce the administrative burden
of holding two separate licences for similar projects under the PHAI portfolio

PHAI Quick Facts

  • The PHAI represents the federal government’s response to the community-requested solution for the cleanup and local, long-term, safe management of historic low-level radioactive waste in the municipalities of Port Hope and Clarington.
  • The waste is the result of the refining practices of former Crown Corporation, Eldorado Nuclear Ltd., and its private sector predecessors. The original Eldorado refining operation and plant were established in the 1930s without consultation with Indigenous peoples of the area.
  • Canadian Nuclear Laboratories is implementing the PHAI on behalf of the federal Crown Corporation, Atomic Energy of Canada Limited with federal funding of $1.28 billion.
  • The Port Hope Project involves the cleanup of approximately 1.2 million cubic metres of historic waste at various sites within the municipality and its long-term safe management in an engineered, aboveground mound located south of Highway 401 and west of Baulch Road in the Municipality of Port Hope.
  • The Port Granby Project involves the removal of approximately 1.3 million tonnes of waste from the former waste management facility at the south-eastern boundary of the Municipality of Clarington. Waste removal is complete and the mound was capped and closed in the fall of 2021.
  • CNL is committed to sharing timely, accurate information about current and planned PHAI activities with Indigenous communities and organizations, key stakeholders, members of the public and environmental groups.
  • The PHAI is regulated through CNSC Waste Nuclear Substance Licences issued by the CNSC. Licence requirements include strict site protocols for safety, security, radiation protection, environmental protection, occupational health/safety to minimize risks to the public, workers and the environment.
