We would be better served if Canada paid the 2% of GDP to defense that their NATO treaty commitment obligates them to.  They're one of the worst violators, relying on the US to protect them.

Canada also has the highest immigration rate per capita in the world, and it's becoming a serious problem.  Lots of low-skilled people on welfare who don't assimilate and reject Western values.
