You keep going on about Dawson Creek, but I know Dawson pretty well, I live there. My partner's a fourth or fifth generation local, odds are you're not going to know it better.
Yes, housing is cheaper here, but there's a caveat to that. Dawson Creek is a popular hub or immigrants precisely because housing is less expensive. Younger folks are also already doing what you've said, in fact they've been doing it for a while. Thing is, Dawson Creek is a small town of roughly 12k, it's housing options aren't unlimited. Nor are it's community resources or local infrastructure. The general feeling amongst folks I know up here is that the province doesn't really give as much of a shit about northern communities.
As demand rises it's likely prices will too.
As for don't spend money, I don't go throwing money around, but that doesn't change the fact that costs of living outpace the income of many. It's not all frivolous spending, things are tighter financially for most people than they were prior to Covid and wages have not kept pace.
None of the doctors in town are taking on new patients for example, and it's rare to hear about positive hospital experiences. It's not unusual for folks to have to drive four or five hours (weather depending) through the pine pass in order to access care in Prince George. It's not as if we can just hop skip across the Alberta border, it's more complicated than that because of interprovincial yadda yadda yadda.
It's also not as simple as move north or move east, a lot of jobs can't be done remotely, and people have families, communities, and other obligations to consider. Not everyone has the brain, learning style, or skill set for trades either, that's not the surefire solution you seem to think it is. There are needs elsewhere anyway, the Canadian population is aging, a lot of the work force is aging, there will needs to be replacements. Thing is, if folks can't afford to live in certain areas, where are those replacements going to live?
I was born and raised in Nanaimo, I know the island very well, a lot of the demographic on the island is on the older side. Newly wed or nearly dead is the saying, thing is, if younger professionals are priced out who is going to care for all these aging folks? An exodus of young folk from larger cities and towns isn't necessarily a good thing. Nor is an exodus of young professionals from the country in general.
The idea of pushing folks north just to have a chance at home ownership is troubling, the millennial generation is now the largest age cohort in Canada, Canada's workforce is aging. There's no getting around the fact that younger, but not exclusively younger, demographics are going to need to be able to afford housing all over Canada.
