The actual damage is probably way worse than that, it just hasn't been realized. But, there are still like 62,000 other active members. Also, it's Canada*, in the entire history of Canada as an entity how many times was the Canadian military needed to protect Canada? The answer is almost never. There was a German submarine that fired a torpedo at a loading dock and some Japanese balloons in WW 2 and some attacks across the US border by the Fenian Brotherhood, which had less than 1,000 fighters. They were an Irish republican group trying to pressure the English to leave Ireland. A volunteer Canadian militia outnumbered these people 14 to 1, although they were backed by small numbers of English troops and seamen.

*remember Canada didn't exist as Canada until the middle of 1867, so don't try and tell me the war of 1812 involved them.
