SREC's registry confirms the licence is real and in good standing. From there, ask directly for a list of properties the agent has sold in Saskatoon in the past year and cross-check a few addresses against SRA sold data rather than trusting a testimonials page, since testimonials are the easiest part of a website to curate.
Saskatchewan REALTORS Association recorded 446 sales across the city last month alone, so an agent who can point to specific, verifiable closings inside that volume has a provable record. One who cannot, or who only shows listings still active or expired, does not.
Joel Dyck welcomes that kind of check and will point you to specific closed Saskatoon sales rather than asking you to take his word for it. Get your hand-reviewed valuation from Joel Dyck.
