This exhibition shows how Canadian uranium and Canadian scientists contributed to the development of the atom bombs that were dropped on Hiroshima and Nagasaki in August of 1945. Through Canadian government intervention and nationalization during World War II, mining ventures and industrial processing at Port Radium in the Northwest Territories, in Port Hope, Ontario, and in Trail, B.C. were integrated into the American Manhattan Project that ushered in the nuclear weapons age threatening human civilization today.
