Ontario has awarded contracts to 12 manufacturers and suppliers in the Greater Toronto and Hamilton Area (GTHA) for Ontario Power Generation’s (OPG) Darlington New Nuclear Project (DNNP), where the province says the G7’s first small modular reactor (SMR) is being built.
The contracts cover critical components and services, including pumps, transformers, specialized steel and concrete. The province says they will add more than $110 million to Ontario’s GDP, create new jobs and sustain hundreds more, while opening new markets for sectors hit by U.S. tariffs.
The largest contract went to Toronto-based St. Marys Cement, awarded $50.2 million to supply concrete and operate a high-density concrete wet batch plant for the project, creating 19 new jobs.
Other recipients include:
- Smith & Long (Markham): $14.6 million for temporary and permanent electrical power systems, creating seven jobs
- WillScot (Gormley): $10.7 million for a construction island trailer complex, creating 25 jobs
- ASI Marine (Hamilton): $9.2 million to assist with tunnel-boring machine operations
- Curtiss-Wright Nuclear Canada (Newmarket): $8.9 million for airlocks, the specialized entry systems that let workers and equipment move safely in and out of the facility
- Northern Transformer (Maple): $4 million for power transformers
- Armstrong Fluid Technology (Toronto): $3.9 million for pumps and a pumphouse enclosure
- Promation (Oakville): $3.9 million for a Fine Motion Control Rod Drive platform, creating four jobs
- Hooper Welding (Oakville): $1.7 million for steel for the project’s Diaphragm Plate Steel Composite modules
- Aquatec (Maple): $1.7 million for wastewater treatment services
- Arkbro Industries (Mississauga): $1.6 million for a gantry tower for the transformer yard
- Clyde Union Canada (Celeros Flow Technology) (Burlington): $300,000 for a pump and pump motor, creating 15 jobs
Construction continues at the site, where crews have placed the 2.1-million-pound reactor basement, the first new nuclear foundation laid in Canada in more than 30 years. Work is also progressing on the reactor and turbine buildings and on the infrastructure needed for all four planned SMR units.
The province says it has worked with OPG to ensure 80 per cent of project spending goes to Ontario companies.
