The project officially lasted from 1942 to 1946, although government-approved research into nuclear weapons began in 1939 after a series of major breakthroughs in nuclear science in the 1930s.
Nov 16, 2021 · Abstract. During the Second World War, Canada made several important contributions to wartime nuclear research efforts. The three main contributions were: establishing a domestic nuclear research laboratory in Montreal to investigate heavy water reactor; creating supply chains to provide uranium oxide, heavy water, and polonium to the Manhattan Project; and the direct contributions of several ...

The field of nuclear physics emerged at the turn of the 20th century. In 1896, Henri Becquerel discovered radioactivity. The following year, J.J. Thompson discovered the electron. In 1898, Marie and Pierre Curie discovered radium and extensively documented the phenomenon of radiation. Another breakthrough came in 1905. That year, Albert Einstein in...
Canadian nuclear physicist George Laurence experimented with uranium fission as early as 1939–40. His goal was to develop a uranium-graphite reactor. Laurence carried out his experiments in Ottawa for the National Research Council. The uranium he used came from the Eldorado Mine in Port Radium, Northwest Territories. Laurence did not succeed in bui...
The British government began to plan a nuclear weapons research project in 1940. Codenamed “Tube Alloys” when it launched the next year, it was the world’s first nuclear weapons research program. At first, Tube Alloys was based at the Cavendish Laboratory at the University of Cambridge. But the British were low on resources and wary of the threat p...
At the Quebec Conference of 1943, Britain and the United States merged their nuclear weapons research into a single effort. Britain had been leading in nuclear research in the late 1930s and the early years of the war. But the conflict was draining resources and Britain had fallen behind. The joint effort agreed to in Quebecwould later assume the c...
Research at the Montreal Laboratory moved to new facilities in Chalk River, Ontario in 1944. (See Nuclear Research Establishments). Chalk River had two experimental reactors. The first was known as ZEEP (Zero Energy Experimental Pile). On 5 September 1945, ZEEP achieved a sustained and controlled nuclear reaction using uraniumand heavy water. It wa...
During the Manhattan Project, the Eldorado Mine in Port Radium, Northwest Territories, employed Dene people from the community of Déline to carry uranium. Some Dene believe that uranium from this mine became the fissile material in the bomb dropped on Hiroshima on 6 August 1945. This point is disputed by some historians, including Robert Bothwell, ...

During the Second World War, Canada made three significant contributions to the development of nuclear technology: a domestic nuclear research program, the production of essential raw materials for the Manhattan Project, and the contributions of Canadian scientists working directly for the Manhattan Project.

The AEC would take over all Manhattan Project operations starting in January of 1947, officially ending the Project. 40. The scientists involved in the Manhattan Project had mixed feelings about the legacy of their work. They had, in their eyes, opened up entirely new questions about the role of science in society.
