I wonder how much of this is just the political winds. Under the George Bush days there were similar sentiments and attitudes, but it never went anywhere and SV still remained dominant. Canada has long tried to capitalize on the US political situation with mixed results.

Salaries are low, most of Canada has poor weather and unaffordable housing prices in the major cities. I guess if you're willing to stick it out you get citizenship, but a far less valuable citizenship compared to other western countries.

I'm also curious as to if and when the immigration situation is going to hit Canadian politics as it did in the US. The facade of being pro immigration is exactly that, there are just as many racists in Canada as there are in the US.
