And also not a coincidence that the largest surge in price and demand in Vancouver, and then Toronto, has coincided with the Federal Government's  10 year multi-entry visitors visa, that is being used for de facto residency.

You can live here for ten years at a time, buy property to live in or invest in,  not declare your overseas income or assets for taxation, available yourself of all community amenities, and put your kids in school (private or pay for a public placement).

Almost a million of these visas were issued in a couple of years to one country alone - China.
