I apportion the blame 5% to the Martin Liberals ending rental construction subsidies, 5% to the Trudeau and Harper governments for ignoring the writing on the wall pre-pandemic, 5% to the BC Liberals/United party for deliberately celebrating their province's housing market as a casino, 5% to the Ontario PC government for exploiting the problem to hand out goodies to donors instead of solutions, another 5% to the Federals again for their lackluster post-pandemic response, and 99% to the various Municipalities across Canada that actually caused and continue to cause this massive problem and if every planner and councilman was fired tomorrow and we shifted to Kowloon Walled City anarchy it would be a net positive for Canada.

Edit: yes I know the math doesn't add up there but it's real-estate that's a given.
