You are targeting the wrong government departments.

The government departments that caused Vancouver house prices to skyrocket to dozens of times the average annual local income...

... were mainly the immigration-related departments in Ottawa and Quebec City who decided, for the first time in Canadian history, to start in the mid 1980s to intentionally and massively vacuum up overseas millionaires en masse through investor immigrant programs.

The result of that radical and massive change to Canada's prior immigration selection system, that is what got us this upheaval of massively skyrocketing house prices in Vancouver.
