Bruce Power 

  • Joined in 2001

  • Voting member on the Board of Directors

Bruce Power, Canada’s first private nuclear generator, is an electric utility partnership among TransCanada Corp., Borealis Infrastructure, the Power Workers’ Union and The Society of Energy Professionals. It provides 30% of Ontario’s power from its location in Tiverton, Ontario (250 km north of Toronto). ​The eight-unit ​​plant has more than 4,000 employees, over 90% of whom own a part of the company. In 2016, Bruce Power began its Life-Extension Program, enabling its units to operate safely to 2064.

For over 30 years, the four reactors at Bruce Power’s Bruce B Generating Station have produced a steady supply of the world’s Cobalt-60 medical isotopes, used for treatments of cancer and other diseases and sterilization of medical devices. Through its Isotope Production System launched in 2022, Bruce Power continues to facilitate the research and production of new isotopes, bringing hope to patients across the world.

New Brunswick Power (NB Power)

  • Joined in 1984 (founding member)

  • Voting member on the Board of Directors

New Brunswick was Canada’s third province to produce electricity using nuclear energy. The largest electric utility in Atlantic Canada, NB Power operates the region’s only nuclear facility, Point Lepreau Generating Station, which went into service in 1983. 

With one reactor, Point Lepreau was the first CANDU-6 licensed to begin commercial operation. The unit supplies about 30% of the energy consumed in the province. Its 2012 refurbishment extended the station’s life to 2039; and, since returning from refurbishment, it has been recognized for continually improved performance and excellence in plant operation. NB Power and the provi​​ncial government are partnering in research for the potential development of small modular reactors with two private-sector companies.

​Ontario Power Generation​ (OPG)

  • Joined in 1984 (founding member)

  • Voting member on the Board of Directors

​A successor company of the former Ontario Hydro, OPG is wholly owned by the Province of Ontario. Ontario Hydro was one of the founding members of our predecessor, CANDev (CANDU Development). As one of the largest and most diverse clean power producers in North America, OPG currently operates Darlington, Pickering A and Pickering B nuclear generating stations in addition to other assets, including a fleet of hydro-electric stations. 

Pickering A (in service in 1971) and Pickering B (added in 1983) produce approximately 14% of Ontario’s electricity. With the support of the Province of Ontario, OPG is planning for the refurbishment of Pickering Nuclear’s Units 5 to 8.

Darlington Generating Station has produced about 20% of the province’s electricity since the early 1990s. Its refurbishment is expected to create 14,200 jobs per year and extend the life of the plant by 30 years. OPG is also leading the development of North America's first commercial-scale small modular reactors at the Darlington site, with planning and licensing underway for three additional SMRs. Pending regulatory approvals, the total output of the Darlington New Nuclear Project would be 1,200 megawatts: enough electricity to power about 1.2 million homes.​

Saskatchewan Research Council (SRC)

  • Joined in 2024 

Since its establishment in 1947, SRC has been a cornerstone of scientific research and innovation in Saskatchewan and beyond. As a Treasury Board Crown Corporation, it operates under the Saskatchewan government, with a workforce of over 350 professionals.

SRC’s nuclear expertise covers uranium exploration, mining, milling, environmental protection and research. It has managed the world's largest uranium laboratory and successfully decommissioned the SLOWPOKE-2 nuclear research reactor after over 38 years of safe operation. Leveraging this experience, SRC has embarked on pioneering efforts to license and demonstrate the first microreactor in Saskatchewan, working with communities, industry and Indigenous groups. Microreactors can be deployed in remote areas to generate industrial heat and electricity for various applications.

​International Members

China National Nuclear Operations Management​ ​(CNNO)

  • Joined in 2003

​In 1996, Atomic Energy of Canada Limited (AECL) signed a $4-billion contract for the sale of two CANDU 6 reactors to China, with construction beginning in June 1998. CNNO is the operator of the Qinshan Phase III (Third Qinshan) nuclear power plant situated in China’s Zhejiang Province. It is adjacent to Qinshan Phase I (Unit 1) and Qinshan Phase II (Units 2 and 3) nuclear power plants.

Qinshan Phase III (Units 4 and 5) are the first heavy water reactors to operate in China. Qinshan Unit 4 began commercial operation on Dec. 31, 2002 and Qinshan 5 on July 24, 2003. Qinshan is the first CANDU-6 project to use open-top reactor building construction and the first project where commercial operation began earlier than its projected date. Approximately one-third of all new nuclear power plant construction in the world is currently taking place in China.
