Ontario Power Generation’s (OPG) Darlington Small Modular Reactor (SMR) project is moving full steam ahead, marking a milestone in Canada’s push toward cleaner energy. Located in Clarington, Ontario, the Darlington site is the only Canadian location with regulatory approval for new nuclear construction. The project is currently in the early stages of site preparation, with construction expected to begin in 2025 and the first unit operational by 2029. This project is a critical step in meeting Ontario’s future electricity demands while significantly reducing greenhouse gas emissions.
Benefits of the Darlington Nuclear Project
The Darlington SMR will be Canada’s first grid-scale small modular reactor, capable of generating 300 megawatts of electricity—enough to power 300,000 homes. Once operational, this reactor will contribute to Ontario’s goal of phasing out natural gas-fired generation and moving toward net-zero emissions.
OPG has partnered with GE Hitachi Nuclear Energy to design and build the BWRX-300 reactor, which is expected to play a key role in ensuring a stable and sustainable energy supply for the province. The SMR design offers enhanced safety features and a smaller footprint compared to traditional nuclear reactors, making it a practical solution for expanding clean energy capacity.
The project will boost Ontario’s economy as well. During construction, Darlington will create approximately 2,000 jobs and provide ongoing employment for around 200 workers once the reactor is operational. These jobs will support skilled trades and boost the local economy by creating demand for services, materials, and expertise. OPG estimates that the project will contribute billions to Ontario’s economy over its lifespan, offering long-term stability to the energy sector and communities in the region.
Clarington residents will also benefit from infrastructure improvements and increased economic activity in the area. Local businesses, contractors, and service providers will experience increased demand, strengthening the community’s economy.
A step toward Ontario’s energy future
The Darlington site has been carefully selected and rigorously assessed to ensure safety and environmental sustainability. The Canadian Nuclear Safety Commission (CNSC) has completed an environmental assessment and granted a site preparation license. As part of OPG’s commitment to transparency and safety, ongoing monitoring and community engagement will continue throughout the project.
This project is a crucial piece of Ontario’s energy puzzle, addressing both environmental and economic goals. The Darlington SMR will reduce reliance on fossil fuels while supporting a growing population and increasing energy demands. As the province pushes forward with cleaner energy solutions, this project sets the stage for additional SMR developments across Canada.
