Only mentioned as an aside, but for Vancouverites, this has been very painful.
Uniquely Quebec manages its own immigration (let's not get into it) and they have an investor immigration scheme that essentially sells citizenship for a pittance. Of course since persons have freedom of movement there's nothing stopping persons who buy citizenship in Quebec for moving to Vancouver, which almost all of them do.
Accordingly while British Columbia has enacted various foreign investor taxes to try to limit the distortions from foreign money on the real estate market, there remain significant impacts of foreign wealth in Vancouver and BC.
Sadly federal politicians aren't in much of a rush to annoy the Quebec government by playing hardball on this issue as Canada has an election coming up and Quebec has heaps of seats in play.
