I'm not sure about rent control. That's a decision that would have to be made by governments. I won't pronounce on that. Other jurisdictions have done that in the past, with some different results.
One thing is for sure, without additional investments, and with a growing indigenous population, it's clear that the need for affordable and adequate housing will probably keep on growing. Unless indigenous Canadians are finding high-paying jobs at a much faster rate than the rest of the population, or rental rates go down all of a sudden, which would be very surprising, in all likelihood this issue, without additional investments by governments at all levels, is very likely to continue to increase.
