Sadly, every layer of every government in Canada is determined to do explore literally every other possible option before allowing homes to be built. And realistically, fixing the problem will take decades.
Years before governments come around.
Years more before they finish their endless studies and legislation and actually legalize housing.
Once housing starts getting built, it will be a knock-down battle to keep the changes. At the same time, we won't have the capacity built up yet to build it, so years more for new industrial capacity to come online - more companies, more trained personnel, more equipment.
And then even more years for the supply to finally catch up with the demand.
My oldest kid is 14 and he's either he's living in my basement until he's 40 or he's going to have to move to Texas.
As a Canadian, I think a big part of it is that elections (both federal and provincial) can often be battles for the suburbs surrounding metropolitan areas. Suburbs often end up being kingmakers (see 2015, 2019, and 2021 federal elections or BC’s 2020 election) so their priorities are often continually represented.
To me as a foreigner living here its glaringly obvious that the affordability problem is at least in great part due to SFH zoning. I think basically anyone not native to the US or Canada immediately understands this.
I'm glad to see this topic being increasingly discussed among locals instead of just the usual boogeymen (foreign investors is #1).
