What is actually measured and published on a fixed schedule is the local supply of homes for sale, not a future target. The Saskatchewan REALTORS Association reported 1.63 months of supply most recently, which tells a seller far more about today's competition than any long-range housing needs estimate does.
Housing needs projections also mix together every housing type, rental and ownership, apartment and single-family home, across the entire city, while a seller only cares about their own segment and their own neighbourhood. A projection for the city as a whole says very little about how many buyers are actually looking at homes like theirs this month.
If the question behind the question is whether now is a good time to sell, months of supply and recent sales answer it better than a growth target does. Get your hand-reviewed valuation from Joel Dyck.
