Yeah Canada landed 15,000 troops, plays a major roll in dday. But ill have to see some facts on the Third largest navy. America had the largest, then japan then germany then canada. Japan had a massive navy and germany had a massive uboat fleet. 120 ships is a nice sized navy but not enough to hold the rank of third.
Edit* i looked it up, its true. During the years of 1945-1950 Canada had the worlds third largest navy...
1.U.S Navy
2.U.K. Royal Navy
