a report from https://www.zoocasa.com/blog/canada-us-home-affordability-comparison/
suggests calgary has the most affordable real estate among the 35 major markets studied.
This is interesting as income averages appear to dictate much of the relative measure of affordable housing, not just pricing.
I think some of these aggregate stats distort the Calgary market because the inner city areas are vastly more expensive than the sprawl communities. While low cost housing in Calgary is clearly available, one must pay a serious location and convenience tax to purchase the cheaper stuff.
