About the PHAI

One Initiative, Two Projects

The Port Hope Area Initiative (PHAI) represents the federal government’s commitment to respond to the community-recommended solutions for the cleanup and local, long-term, safe management of historic low-level radioactive waste in the municipalities of Port Hope and Clarington. A legal agreement, finalized in March 2001, between the Government of Canada and the two municipalities, launched the PHAI by defining the framework and setting out the responsibilities for the Port Hope Project and the Port Granby Project.

Through its Historic Waste Program Management Office (HWP MO), Canadian Nuclear Laboratories is implementing the PHAI on behalf of Atomic Energy of Canada Limited, a federal Crown corporation.

PHAI_PH_logo_smallThe Port Hope Project involves the construction of a long-term waste management facility and supporting infrastructure for the safe, long-term management of approximately 1.2 million cubic metres of historic low-level radioactive waste, cleanup of the waste from various sites in Port Hope and its transportation to the facility, and long-term maintenance and monitoring.

PHAI_PG_logo_smallThe Port Granby Project involves the construction of a long-term waste management facility and supporting infrastructure for the safe, long-term management of  approximately 450,000 cubic metres of historic low-level radioactive waste, currently located at an existing site on the shoreline of Lake Ontario in Southeast Clarington. The waste will be relocated to a new, engineered aboveground mound to be built away from the lake approximately 700 metres north of the existing site.
