Port Hope Area Initiative

The historic low-level radioactive waste stored in the municipalities of Port Hope and Clarington originates from the radium and uranium refining and processing operations carried out from the 1930s to the 1980s by Eldorado Nuclear Limited, a former Crown corporation. The Port Hope Area Initiative (PHAI) represents a commitment by the Government of Canada to respond to the community-recommended solutions to this long-standing environmental problem. The two remediation projects that are part of the PHAI are the Port Hope Project and the Port Granby Project. Canadian Nuclear Laboratories (CNL) is implementing the PHAI on behalf of Atomic Energy of Canada Limited. The CNSC has regulatory oversight, and it has approved both clean-up projects.
