Oh boy. I missed out on THIS?
Sorry, guys, it’s my duty as a Canadian to post in here :-D
Canada’s economy aside, as she would have supported the British regardless of her official political and military stance in the war, there are other things to consider.
The Canadian military was the only military worth noting that could have interfered with a German invasion. Nearly the entire British army’s heavy equipment was left at Dunkirk, and her factories were at the point of collapse from the amount of bombings the Germans employed against them.
That is where we should discuss some more, the Battle of Britain. Canada is where a huge percentage of pilots from across the Commonwealth were trained. I believe the number is as high as 90% of the pilots that fought over Britain were trained in the Canadian wilderness.
In addition, the Canadian aviation projects that occurred between 1939 through 1942, when America’s input was seriously felt, was what kept the Allied air fleets in the skies to defend Britain in the first place.
Everyone knows air superiority is what wins a war.
