Saskatoon's own supply pressure is the more relevant number here. The Saskatchewan REALTORS Association most recently measured 1.63 months of supply in the city, and infill and density policy is one of the tools the City of Saskatoon uses to respond to exactly that kind of pressure over time.
In practice that means a homeowner in an established neighbourhood may now be able to add a secondary suite, or on some lots a second small dwelling, where an older zoning bylaw would not have allowed it. Rules vary by lot and by neighbourhood, so the only reliable way to know what a specific property allows is to check directly with the City of Saskatoon.
Joel Dyck tracks these zoning changes because they change what a property is actually worth, not just what it looks like from the street. Get your hand-reviewed valuation from Joel Dyck.
