The Montreal Laboratory in Montreal, Canada, was established by the National Research Council of Canada during World War II to undertake nuclear research in collaboration with the United Kingdom. After the Fall of France, some French scientists escaped to Britain with their stock of heavy water, and joined the British Tube Alloys project to build an atomic bomb. In 1942, it was decided to relocate the work to Canada. The Montreal Laboratory was established in a house belonging to McGill University, but moved to the Université de Montréal in March 1943. The first laboratory staff arrived at the end of 1942. John Cockcroft became director in May 1944.
