The Central and Eastern Ontario Isotope Alliance has officially joined the Canadian Nuclear Isotope Council (CNIC), marking another important milestone for Durham Region’s growing role in the global production of life-saving medical isotopes.
The regional alliance, established two years ago by Ontario Power Generation (OPG), the Municipality of Clarington, and several industry partners, was created to strengthen collaboration across Ontario’s expanding medical isotope sector. By joining the CNIC, the alliance will work alongside researchers, healthcare providers, government organizations, and industry leaders to further advance isotope innovation and improve patient care.
Medical isotopes play a vital role in modern healthcare. They are used to diagnose diseases, sterilize medical equipment, and treat several forms of cancer, including liver, prostate, neuroendocrine, head, neck, and cervical cancers.
Darlington Nuclear Generating Station in Clarington has become North America’s largest producer of medical isotopes. Using its unique CANDU reactor technology, the facility produces isotopes without interrupting electricity generation, ensuring a reliable supply for healthcare providers around the world.
Ontario Power Generation subsidiary Laurentis Energy Partners produces the critical medical isotopes Yttrium-90 (Y-90) and Lutetium-177 (Lu-177) at Darlington. These isotopes support targeted radionuclide therapies that deliver radiation directly to cancer cells while reducing damage to healthy tissue. The treatments are providing new hope for patients with difficult-to-treat cancers, and demand continues to grow internationally.
The isotopes, produced through Laurentis’ advanced irradiation system developed with BWXT Medical Ltd., are currently distributed to more than 30 countries worldwide. Commercial production began in 2023, with plans to significantly expand output over the coming years and further strengthen Ontario’s position as a global leader in medical isotope production.
Clarington Mayor Adrian Foster said joining the Canadian Nuclear Isotope Council reflects the region’s commitment to collaboration, innovation, and improving health outcomes for cancer patients while supporting economic growth across Central and Eastern Ontario.
The alliance brings together municipalities, healthcare organizations, research institutions, isotope developers, and industry partners, including Laurentis Energy Partners, Ontario Power Generation, Canadian Nuclear Laboratories, Nordion, Invest Durham, and several regional municipalities. Together, they aim to identify supply gaps, strengthen healthcare partnerships, support innovation, and expand Canada’s global leadership in medical isotope production.
Officials believe the Central and Eastern Ontario Isotope Alliance will continue to play an important role in advancing both healthcare innovation and economic development while helping improve access to life-saving treatments for patients across Canada and around the world.
