During the Second World War, the Royal Canadian Navy expanded significantly, ultimately gaining responsibility for the entire Northwest Atlantic theatre of war. By the end of the war, the RCN had become the fifth-largest navy in the world after the United States Navy, the Royal Navy, the Imperial Japanese Navy, and the Soviet Navy, with over 300 vessels. During the Battle of the Atlantic, the RCN sank 31 U-boats and sank or captured 42 enemy surface vessels, while successfully completing 25,343 merchant crossings.
I believe that by the end of the war, Canada had grown to third, surpassing both the Japanese and the Soviets.
Oh, I know our history, but we have far more immediate concerns, like eating.
