Powering Ontario

Securing Ontario’s future as an energy superpower

As Canada faces economic uncertainty, we have a plan to Protect Ontario—today and for generations.

Nuclear power accounts for about half of Ontario’s electricity supply. For more than 50 years nuclear has delivered the clean, affordable and reliable electricity we need for homes, business and industry.

That’s why we’re building a competitive, resilient and self-reliant economy with a nuclear expansion plan that will create 150,000 new job opportunities and adds over $800 billion to Canada’s economy.

Building new large-scale nuclear facilities

We are building the first large-scale nuclear facilities in Ontario in over 30 years, including exploring two new sites:

• Ontario Power Generation’s Wesleyville site (Port Hope) — to generate up to 10,000 megawatts (MW) of power, enough to power 10 million homes, and contribute $235 billion to Ontario’s GDP over an estimated 95-year project life
• Bruce Power’s Bruce C project — to generate up to 4,800 MW, enough power for 4.8 million homes

Small modular reactors

We’re building the G7’s first grid-connected small modular reactor (SMR) at the Darlington new nuclear site. Once the four units are completed, the ground-breaking SMR project will:

• add $38.5 billion to Canada’s GDP over the next 65 years
• create an estimated 3,700 highly skilled, good-paying new jobs in the province
• generate 1,200 MW of electricity, enough to power 1.2 million homes

Refurbishing existing nuclear generating stations

We’re increasing nuclear energy generation capacity, including refurbishments at Darlington, Bruce and Pickering Nuclear Generating Stations.

These refurbishments will:

• maintain more than 12,000 MW of existing generation capacity, enough to power 12 million homes.
• create tens of thousands of good-paying new jobs

Saving lives with nuclear isotopes

Ontario’s nuclear reactors create life-saving medical isotopes, producing:

• Cobalt-60: used to sterilize medical equipment and treat head, neck and cervical cancers
• Lutetium-177: used in targeted therapy for prostate cancer and neuroendocrine tumors
• Molybdenum-99: used in diagnostic scans for bones, heart, lung, kidney and cancer detection
• Yttrium-90: used in cancer treatments
• Helium-3: used in medical imaging

Establishing a strong nuclear supply chain

Ontario’s world-leading nuclear supply chain creates over 75,000 good-paying jobs in every corner of the province and reinforces our commitment to skilled trades.

Canada is home to one of the world’s only fully integrated nuclear fuel supply chains, shared between Saskatchewan’s uranium mining sector and Ontario’s processing, conversion and manufacturing expertise. More than 90% of spending on Ontario’s nuclear refurbishments will be spent in Canada to strengthen local businesses and generate more jobs across the whole nuclear supply chain.

We’re further strengthening this supply chain and creating more jobs through agreements with more than 80 Ontario-based companies to support new SMR construction using skills, expertise and technologies that can be exported around the world, including:

• component manufacturing
• engineering
• construction
• project management

We are also exploring opportunities to deploy Ontario-made nuclear technology and SMR expertise to Belgium, Estonia and Poland. With early leadership in supply chain development, these projects are opening new markets, creating good-paying, long-term jobs domestically and globally, increasing economic growth and ensuring a more secure energy future for the province.
