Clarington is one of Canada’s most significant nuclear host communities, with a diverse range of facilities and projects that span electricity generation, innovation, and environmental remediation.

The municipality is home to the Darlington Nuclear site, operated by Ontario Power Generation, which includes:

• Darlington Nuclear Generating Station – A four-unit CANDU facility providing a significant share of Ontario’s electricity
• Darlington Refurbishment Project – A major multi-year infrastructure project extending the life of the station
• Darlington Waste Management Facility – Safe, long-term storage of nuclear waste materials
• Darlington New Nuclear Project – Canada’s first grid-scale Small Modular Reactor (SMR), based on the BWRX-300 technology

In addition to its role in power generation, Clarington is also home to the Port Granby Project, led by Canadian Nuclear Laboratories. This project focuses on the safe, long-term management of historic low-level radioactive waste through the relocation and containment of legacy materials in a modern, engineered facility designed to protect the environment.

Together, these facilities and initiatives reflect Clarington’s role across the full nuclear lifecycle—from clean energy production and innovation to environmental remediation and long-term stewardship
