Canada's nominal GDP per capita is roughly $53,800 USD, which places it nearly on par with Mississippi
also Canada admits people from third world countries at a per-capita rate roughly four times higher than the United States, with none of the enforcement agencies capable of tackling illegal immigration which a lot of this demographic engages in. It's difficult for ICE now imagine Canada which has no such enforcement on the same scale
my point is that Canada has a smaller economy but imports more from the third world than its much richer and powerful neighbor.
this is not a sustainable arrangement.
A massive federal agency rounding up illegal immigrants actually isn't that effective, as has been seen in the USA. What actually works is making it impossible to find a job or housing without proof of citizenship - which is being done in Canada BTW
if illegal presence has almost no chance of interior enforcement, then overstaying or working illegally becomes a rational bet. If arrests, detention, removals, and employer raids become credible again, behavior changes that's the whole point of ICE raids they know they can't deport millions of people but to change the behavior of the demographic that they are targeting. This is something that Canada neither has the political capital to pursue.
No, Canada is not as poor as Missisipy.
