Canada saw enormous growth during World War II, going from a limited amount of warships to becoming the third largest navy in the world after the Axis powers were defeated and the role they played in aiding the USN in intelligence. Their primary role in protecting merchant ships from North America to Britain was ultimately successful, though that victory was shared with the major Allied powers. Throughout the war Canada had made 25,343 successful escort voyages delivering 164,783,921 tons of cargo. By the end of the war, German documents state that the Royal Canadian Navy was responsible for the loss of 52 submarines in the Atlantic. In return 59 Canadian merchant ships, and 24 warships were sunk during the battle of the Atlantic.
