The problem is lack of supply. Canada's population grew twice as much as new housing over the past 5 years. And Canada is a very desirable place to live which makes our "product" attractive. Relatively good social services, tolerance, lower crime and taxes than the US and Europe (I'm including private health costs in US taxes since health is what so much of our taxes pay for), good job prospects and schools, beautiful environment with low extreme weather problems. There was a Forbes article years ago surveying the vulnerability of major cities around the world to environmental harm (rising waters being a big one for so many cities) in the next 50 years and the article's conclusion was to buy Toronto real estate due to the looming environmental refugee crisis because we have almost no risks (earthquakes, floods, drought) while higher temperatures will make it more pleasant.
In Toronto especially we need to mandate more family size condos since the open land is long gone. Yet you can still walk down most of Bloor/Danforth without seeing a building over 2 stories even though the subway runs under it. Perhaps work from home will spur more development outside of the Toronto area as well.
