King asserted Canada's autonomy and convened the House of Commons on September 7, nearly a month ahead of schedule, to discuss the government's intention to enter the war. King affirmed Canadian autonomy by saying that the Canadian Parliament would make the final decision on the issue of going to war. He reassured the pro-British Canadians that Parliament would surely decide that Canada would be at Britain's side if Great Britain was drawn into a major war. At the same time, he reassured those who were suspicious of British influence in Canada by promising that Canada would not participate in British colonial wars. His Quebec lieutenant, Ernest Lapointe, promised French Canadians that the government would not introduce conscription for overseas service; individual participation would be voluntary. These promises made it possible for Parliament to agree almost unanimously to declare war on September 9. On September 10, King, through his high commissioner in London, issued a request to King George VI, asking him, in his capacity as King of Canada, to declare Canada at war against Germany.

King linked Canada more and more closely to the United States, signing an agreement with Roosevelt at Ogdensburg, New York, in August 1940 that provided for the close cooperation of Canadian and American forces, despite the fact that the U.S. remained officially neutral until the bombing of Pearl Harbor on December 7, 1941. During the war the Americans took virtual control of the Yukon in building the Alaska Highway, and major airbases in Newfoundland, at that time under British governance. King—and Canada—were largely ignored by British Prime Minister Winston Churchill, despite Canada's major role in supplying food, raw materials, munitions, and money to the hard-pressed British economy, training airmen for the Commonwealth, guarding the western half of the North Atlantic Ocean against German U-boats, and providing combat troops for the invasions of Italy, France and Germany in 1943–45. King proved highly successful in mobilizing the economy for war, with impressive
