> It says Canada's population has increased by 15% over the last decade (35 million -> 40 million).
Canada is a developed country with a lot of natural resources; by a lot of metrics, it is one of the top 10 countries with the most natural resources per capita. It should easily be able to increase its housing stock by 1.5% a year at at a national level.
It looks like Greater Toronto went from 5.7 million in 2013 to 6.4 million, ten years later in 2023[0], for a slightly lower rate of growth than the nation as a whole. A cursory search didn't reveal any sources for the number of dwelling units in the GTA over the same time period; but I'm willing to bet that if you combined that plus the expansion in the supply of Canadian dollars, you'll explain most of that growth in home prices.
The money supply in Canada alone more than doubled in the past 10 years[1] vs. the 15% growth in population; so all else equal, you'd expect houses to transact for roughly 74% more CAD in 2023 than in 2013. The Toronto housing price index went from 154.36 in July 2013 to 360.78 this past July, at a 134% growth over the same time period. Most of that difference may be explained by a lack of building in Toronto. I'm sure some of it is other socioeconomic factors (increasing centralization of wealth in cities, etc.), but I don't think any of them are particularly unique to Canada.
If anything else, due to its abundance of open land (granted, not all of it is economically valuable) as well as its natural resource advantages, Canada should be much better suited than other developed countries to be able to handle its housing challenges. The fact that it's not is mostly due to policy choice, which I posit are choices similar to those made in other developed countries.
