Canada’s little-known role in atomic bombings on display

By Anton Wagner

The Hiroshima Nagasaki Day Coalition launched a “Canada and the Atom Bomb” photo exhibition inside Toronto City Hall on August 2. The exhibition of 100 photographs reveals the Canadian government’s participation in the American Manhattan Project that developed the atom bombs that destroyed Hiroshima and Nagasaki in August 1945. 

The exhibition can be viewed in its entirety online at the Toronto Metropolitan University website.

It documents how the Eldorado Mining and Refining Company extracted uranium ore at Great Bear Lake in the Northwest Territories in the late 1930s and shipped the ore to its refinery in Port Hope, Ontario, for sale to the Americans. 

Images by the Montreal photographer Robert Del Tredici focus on the Dene hunters and trappers at Great Bear Lake who were hired by Eldorado to carry the sacks of radioactive ore on their backs for loading onto barges that transported the ore to Port Hope. Many of them subsequently died of cancer. 

Before his death in 1940, the Dene spiritual leader Louis Ayah had prophesied that such an illness would befall the Dene because of white men mining on Dene territory. Ayah also prophesied a nuclear holocaust that would end human civilization. 

Prime Minister Mackenzie King hosted President Roosevelt and Prime Minister Winston Churchill in Quebec City in 1943 where they agreed to have Canada participate in the production of the atom bomb. 

The exhibition highlights this participation by the Canadian government, scientists, industry, and nuclear research laboratories. Posters from the Hiroshima Peace Museum show the death and destruction in the two bombed cities. The exhibition includes five images by Yoshito Matsushige, the only photographer who took pictures in Hiroshima the day the atom bomb exploded overhead.   

“Canada and the Atom Bomb” concludes with photographs showing the efforts by peace activists to persuade Toronto City Council to participate in the world-wide movement to abolish nuclear weapons. In 2017, City Council reaffirmed Toronto as a Nuclear Weapons-Free Zone and called on Prime Minister Justin Trudeau to have Canada ratify the UN Treaty on the Prohibition of Nuclear Weapons.

Setsuko Thurlow accepted the Nobel Peace Prize on behalf of the International Campaign to Abolish Nuclear Weapons in Oslo, Norway, in December 2017. A Hiroshima survivor, Thurlow, now 92, attended the opening of the “Canada and the Atom Bomb” exhibition on August 2. She will also speak at the annual August 6 commemoration at the Toronto City Hall Peace Garden to urge that Canada sign the Treaty on the Prohibition of Nuclear Weapons.
