New innovation is unfolding in Ontario where clean energy meets life sciences—and Durham Region is at the heart of this progress. Home to Ontario Power Generation’s (OPG) Darlington and Pickering nuclear generating stations, and the first connected Small Modular Reactor in the G7, the Region is primed to help advance the province’s ambitious long-term Integrated Energy Plan.
The plan further positions OPG not just as a reliable energy provider, but as a global leader in affordable, secure, and sustainable power. Durham Region already produces nearly 35 per cent of Ontario’s electricity—but OPG is moving beyond electricity generation and harnessing nuclear technology to pioneer life-saving advancements in health and research.
Major developments in isotopes
Worldwide demand for medical isotopes and clean nuclear power is rising. Analysts project the global isotope market will exceed US $20 billion by 2030, driven by cancer diagnostics and targeted therapies.
This growing global demand is matched by Durham Region’s expanding capabilities in isotope innovation and nuclear science. Key isotope developments in Durham include:
- Cobalt-60: Ontario’s CANDU reactors produce about half of the world’s supply of this vital isotope, used to sterilize medical equipment and treat certain cancers.
- Molybdenum-99: In partnership with BWXT Canada, OPG will make Darlington the first commercial power reactor in North America to produce this isotope, which supports over 30 million medical procedures annually.
- Lutetium-177: Used in targeted prostate cancer therapies, with commercial production expected by 2027, potentially treating up to 500,000 patients each year.
- Yttrium-90: Expected by 2026, supporting Boston Scientific’s TheraSphere® liver cancer treatment.
- Helium-3: Extracted from tritium at Darlington for use in quantum computing, neutron research, and advanced imaging, in partnership with Air Liquide.
- Tritium: Used in medical research and to power self-illuminating lights found in watches, exit signs, and instruments. It is safely managed at Ontario’s nuclear facilities and serves as a key source for producing Helium-3.
- Heavy Water: Essential for sustaining nuclear chain reactions in Ontario’s CANDU reactors, with growing applications in medical imaging and drug development.
Key milestones ahead in Durham Region
As Durham Region continues to emerge as a global hub for nuclear innovation, several key milestones are on the horizon that will shape Durham Region’s role in the energy sector, healthcare, and research advancement:
-
Commercial launches of Lutetium-177 and Yttrium-90.
-
Expansion of isotope logistics and supply infrastructure.
-
Growth in partnerships between OPG, universities, hospitals, and private industry.
-
Integration of small modular reactors (SMRs) into Ontario’s energy and research landscape.
By aligning nuclear technology with global health needs, Durham Region is setting a new benchmark for what clean, integrated energy systems can achieve. The reactors that have powered homes and industries for generations are now fueling Ontario’s ambition to lead the G7 as a model of sustainable, science-driven growth for decades to come.
