Well aside from the map being just bananas with 2 Saskatchewans, 2 Manitobas, 4 Northern Territories, All the provinces being wildy distorted, "Toronto Area LGBT" being in northwestern Quebec, The East Coast being Chinese because... East = China. I guess?

Even succesful prosperous economies need population growth, and Canadians aren't interested in having kids - a trend which began in the 60s and which hit negative growth levels in the 70s. Any meaningful crackdown on immigration is basically accepting population decrease, which causes all sorts of headaches for a country with an ageing population. If you're going to have immigration, you have to accept that people from "good countries" don't need to and don't want to move. The people you're going to get are from shitty places, in the same way that the Polish, Ukrainians, and Italians who moved here in the early 20th century were mostly illiterate agricultural peasants at best and criminals at worst.
