List of World War I aces from Canada

This is a list of flying aces in World War I from Canada. A flying ace is a military aviator credited with shooting down five or more enemy aircraft during aerial combat. Canadians served in the British flying services–the Royal Flying Corps, the Royal Naval Air Service, and the Royal Air Force, as Canada had no air arm until the formation of the Canadian Air Force on September 19, 1918.
