Canada supplied uranium for atomic bombs in WWII — 80 years later, the cleanup continues

Gordon Edwards, 6 Apr 25

Atomic Reaction is a documentary feature film dealing with the radioactive history and contamination of the town of Port Hope Ontario, located on the North shore of Lake Ontario just east of Toronto.

Here is a YouTube of the film: https://www.youtube.com/watch?v=8jC1DPOYoQ0

Canada played a key role in chemically refining uranium from Canada and the Congo for use in the first two atomic bombs dropped on the cities of Hiroshima and Nagasaki in 1945. Canada then became the largest supplier and exporter of uranium in the world,  in the post-war period, most of it sold for tens of thousands of nuclear warheads during the Cold War, until the sale of Canadian uranium for nuclear weapons was ended by Prime Miniister Pearson in 1965.

​In the process, the town of Port Hope (where all this refining took place until 1980) became thoroughly contaminated with radioactive wastes that were carelessly discarded and dispersed all about town – dumped into the harbour and into open ravines about town, used in roadways and mingled with the sandy beach, and used in huge quantities as construction material and as fill for up to a thousand buildings – homes, schools, offices, throughout town – requiring a massive radioactive cleanup costing over two billion dollars, resulting in two surface mounds of about a million tons each which will remain highly radiotoxic for many thousands of years to come. The cleanup is stlll ongoing today.

A similarly sized mound of radioactive waste is currently planned for the cleanup of the Chalk River Laboratories, created near the end of World War 2 as a secret site for producing plutonium for the US bomb program among other things. Canada sold plutonium to the US military for weapons purposes.

For 20 years after the end of World War 2. The Chalk River megadump has been approved by Canada’s Nuclear regulator, but two of three court challenges have been successful in delaying the implementation pending legally required consultations with the Algonquin peoples on whose traditional land the megadump would be located, and pending the careful evaluation of alternative sites or waste management options that will not destroy the habitat of several endangered species.
