These are all things that lower taxes and kicking out foreigners can't solve, because that just opens up more property for investors to swoop in and buy. You stop investors from speculating on property and make it illegal for property to go unused and you solve a good chunk of the issue right there.

40% of Canadian Federal MPs are landlords.
Is canada's vacancy rate significantly higher than other developed countries?
The Netherlands had a similar population to Canada in 1950, but today's population is dramatically smaller. Combine that with a historical higher tax rate and investment in infrastructure, this is not something that can be replicated...
I've lived in both and worked outside in -40C and +40C, and both are rough. I'd rather be in Virginia and 4 actual seasons. Or San Diego, where there is just one.
I can’t speak for Canada, but in the case of Australia - there are heaps of small towns in Australia with affordable housing, it is just few people want to live in them. The median house price in Hay, NSW, is only AU$237K (US$157K). Hay is “liveable” - its climate is mild (mean min is 10 deg C, mean max is 24.3 deg C, 368.3 mm annual rainfall). It is on a major river. But, who wants to live in a town of 2500 people which is 5 hours drive from the nearest major city?
