Canadian Merchant Navy: History
With regards to Canada specifically, Canada had no merchant fleet when WWII broke out. Canada had a small "informal" merchant navy built for WWI, but by 1930 it had disappeared. At the beginning of WWII, "within hours of declaring war" September 10, 1939 Canada began rebuilding the Canadian merchant fleet from the ground up. During WWII the Canadian merchant fleet played an important role in the Battle of the Atlantic "bolstering the allies’ merchant fleet due to high losses in the British Merchant Navy."
