The City of Saskatoon's own permit and development approval timelines set the pace here, not a comparison to any other city's process. A slower approval queue for a rezoning or a secondary suite permit means a builder or a homeowner adding density has to wait longer before that unit can actually list.
For a buyer, faster approvals generally mean more competition among new listings rather than less, since new construction and newly legal secondary suites both add to the pool of homes on the market at roughly the same time. For a seller, it means paying attention to what is coming, not just what is currently listed.
Whether faster approvals help or hurt your specific situation depends on whether you are trying to sell into that new supply or buy ahead of it. Get your hand-reviewed valuation from Joel Dyck.
