The Saskatchewan Real Estate Commission requires every brokerage to have coverage in place so a client is never left without representation, which means another licensed agent at the brokerage can step in to handle showings, offers or questions in the interim.
Ask upfront who covers for your agent and how quickly, since a brokerage's answer to that question before you sign tells you more about their reliability than any marketing promise, and it is worth getting the answer in writing alongside the standard $800 to $1,500 closing estimate.
A good brokerage treats continuity as part of the service, not an afterthought handled only when a problem actually comes up. Get your hand-reviewed valuation from Joel Dyck.
