Ontario begins construction of 1st small reactor as it aims to lead in new nuclear technology
- Ontario has approved Ontario Power Generation to begin building the first of four GE Hitachi BWRX-300 small modular reactors at Darlington in 2025.
- This decision responds to Ontario's forecasted 75% electricity demand increase by 2050 driven by industry and data centers, prompting new nuclear development.
- The $7.7 billion project will build the first 300-megawatt reactor and shared systems, each powering 300,000 homes and lasting about 65 years.
- Energy Minister Stephen Lecce emphasized that Ontario is securing its energy future by developing an exceptionally strong and innovative power system, a project that is expected to generate 18,000 jobs.
- This initiative positions Canada as the first G7 country constructing commercial small modular reactors, aiming to lead next-generation nuclear technology development.
