Rt. Hon. Arthur Meighen, address to the Senate, September 10, 1939. In September 1939, Canadians prepared for another war with memories of the Great War still fresh in their minds. It was determined that Canada’s war effort would be concentrated in financial and industrial support, and the first priority would be to secure the nation’s borders. By the spring of 1940, the progress of the war in Europe had changed dramatically. With the German invasion of Denmark, Norway, Belgium and Holland, and the fall of France, Canadians reassessed their own vulnerability. The spectre of a German victory became real.
