No, I still think you're wrong, and the thing you're saying isn't happening (people relocating from major cities to remoter areas) is clearly happening in pretty much all Ontario and BC. At least right now because housing prices have skyrocketed everywhere, not just in the GTA or lower mainland. The pandemic actually drove people
out of urban areas and drove up prices all over the province.
Especially places like Squamish or Collingwood that already had cachet for upper middle class people (but were previously affordable because of the difficulty of commuting from them).
While this is most obviously the case for southern Ontario, I think you'll find actually Timmins or Sault Ste Marie, etc. have gone up at precipitous rates as well. And elsewhere in the country:. Lots of people relocated to Nova Scotia during the pandemic, because housing was cheaper there, they handled COVID better, and they figured they could work remote forever. Housing prices have skyrocketed there, too.
The only place where this didn't happen is in Alberta, where low oil prices and other factors. caused a bit of a net emigration and lower housing prices for a bit and things were quite affordable there. That's now changing as the price of oil goes up.
In the end, there's boatloads of places for people to live in Canada, those places are growing, in some ways regaining a bit of the demand they had prior flattening out in the 1990s & 2000s. The problem is in general that industry and good paying jobs aren't necessarily coming with the people and they're creating an affordability problem for the existing "locals".
In the past people concentrated in the GTA and the lower mainland BC because of jobs jobs jobs. Remote is changing that a bit. For now.
