Canada Has No Enemies, Why Spend 900 Million More Than Last Year to Defend it?

Seriously, who could possibly invade Canada this year? Why are we Canadians spending C$19.1 billion to defend our borders? That is $597 per Canadian. Family of four: $2387.50.

Obviously, Canada doesn't want to end up like WW2 France, Poland or Denmark. The cost of an invasion would be presumably be much higher than $19.1 billion per year. The thing is, as far as I can tell, Canada has no enemies. Sure the Taliban want us out of Afghanistan, but they have no intention of invading Newfoundland or sneaking across the North Pole into Nunavut.

We are simply spending too much on the military.
