They're not war crimes the first time

Everybody needs a hobby.

Yupp..

Act 1 US war of independence founded modern Canada because a) the quebecois ever fearful of cultural erasure, ever relevant today given those US demands, b) those not in favour of a racist dictatorship (yes the anglosphere was turning their backs on a monster they helped create), my family moved to loyalist country, fitting, and c) Britain's desire to legitimize presence by recognizing first nations,... founded canada. The US invaded thinking we would join but Quebec and the indigenous wanted nothing to do with that genocidal regime. An asymetrical response ended American interests.

Act 2 The war of 1812, the US claims they kinda won because they genocided the Iroquois nation and paved a way for continental-scale genocide .. but another goal was conquest of Canada. A goal they failed on every county..britain, its loyalists, and later founders of Canada fought back and said fuck you. Canada 100% repelled the US invasion using asymmetrical warfare.

Act 3 Fuck around and find out.

We were in the big wars (the whole time!), but yes, since then it's been helping someone else do COIN.

Yes, Canadians have no idea what it's like. We've seen even less ugliness than Americans, and when this whole thing started, we had to go to hockey for martial metaphors.

Living in a warzone is a learning curve you can go up fast, though, because you have no choice.

It's also worth noting that Canada has a land border with the USA. They can also pass as generic American, if required.

Asymmetric warfare wouldn't only be focused in Canada. E.g. a coordinated set of drone strikes could basically shatter large portions of the American power grid. There are too many soft, unmanned targets to viably protect, and the lead time of spares is measured in months to years, on some parts.
