Municipality of Port Hope and Canada Reach Landmark Agreement for Historic Waste

For Immediate Release
Tuesday, June 16, 2026 – Port Hope, ON

The Municipality of Port Hope and Atomic Energy of Canada Limited (AECL) have reached a historic long-term agreement to provide greater flexibility and more options for the Port Hope Area Initiative (PHAI) Project.

As the PHAI has progressed - particularly on private properties - it has become clear that it is not always practical or beneficial to remove all of the eligible waste from every location.

Under the agreement, the Port Hope Long-Term Waste Management Facility (LTWMF) will be able to safely accept eligible low-level radioactive waste in Port Hope for up to 100 years after the end of the PHAI project. Now, property owners can choose to leave eligible low-level radioactive waste undisturbed beneath existing features such as mature trees or landscaping, and have the material removed later, if needed. This gives property owners ultimate flexibility and long-term certainty to decide what best meet their needs.

The agreement is also expected to help the project stay on track and potentially even shorten construction timelines. This is a significant achievement for the community.

Specific details of the agreement are as follows:
For the first 20 years following the end of the PHAI project (continuation of current agreement):

• Canada will continue to cover both the transportation and long-term management of eligible low-level radioactive waste, and property owners will still be responsible for excavation and restoration costs.
• The facility will continue to accept the same eligible materials currently managed through the PHAI, including both radiological contaminants and certain associated non-radiological contaminants addressed under the project.

From year 21 and up to 100 years after the end of the PHAI project:

• Canada will continue to provide long-term storage at the facility, while property owners will be responsible for excavation, restoration, and transportation costs, if waste is encountered during future work.
• The facility will only accept material contaminated with radium, thorium, or uranium (radiologically contaminated material), while other material (e.g., soils contaminated with non-radiological material such as arsenic) will need to be managed through provincial systems.

The Municipality will have similar access to the Port Hope LTWMF for radiologically contaminated soils for up to 100 years after the Project concludes. However, the Municipality will be responsible for excavation, restoration, and transportation costs to the site, and will be responsible for managing non-radiologically contaminated materials.

As part of this agreement, the Municipality will receive $8 million, to be placed in the Community Benefit Reserve Fund. This will support the Municipality’s future excavation, restoration, and transportation costs.

This historic agreement reflects a strong and collaborative partnership between the Municipality of Port Hope and Atomic Energy of Canada Limited, grounded in a shared commitment to safety, flexibility, and long-term environmental stewardship. By introducing a practical, property-owner-focused approach, the agreement not only enhances choice for residents but also supports a more efficient completion of the PHAI project.
