Well, IIRC they did burn down the White House in 1812....with the help of the Brits.

Canada has never lost a war with the US fwiw. And suffered proportionally more casualties in Normandy.

Plus, I think Canadian crude oil accounts for something like 60% of US consumption....if you take that out (because the US needs it) then the US actually runs a trade surplus w/ Beaver nation to the tune of $50 billion.
