The CANDU moment
Canada enjoys world-leading expertise in the design, construction, operations, maintenance, and overall program management of nuclear reactors, supported by a highly qualified supply chain. CANDU technology is one of Canada’s most important innovations and remains the nation’s only domestically developed and licensed nuclear technology.
CANDU technology—which uses natural uranium—renowned for its safety, efficiency, and versatility, stands as a source of pride for Canadians and remains a leading force in nuclear innovation worldwide. Six decades after it was first developed, it stands as the linchpin of a vibrant Canadian nuclear ecosystem that supports over 89,000 stable and well-remunerated jobs across a wide variety of professional and skilled trades fields, not to mention researchers at our world-class universities and research institutions.1
CANDU technology remains the only nuclear power technology that coproduces the medical isotopes that are used in cancer-fighting treatments and the sterilization of medical devices. The current CANDU fleet in Ontario produces 50% of the world’s supply of Cobalt-60, which is used for medical device sterilization.2
CANDU intellectual property is owned by the federal government. It is a national strategic asset critical to the energy transition, supporting significant economic opportunities for Canadians.
The Canadians for CANDU campaign calls on the federal and provincial governments to support the only made-in-Canada nuclear technology on the market to help the country reach net-zero and support a thriving domestic nuclear ecosystem.
The choice is clear. It’s time to choose CANDU.
