The Commission's public register lets you search by name to confirm current licence status and brokerage affiliation, and its disciplinary decisions, where they exist, are published rather than kept internal, so a pattern of complaints against a specific agent is not something you have to take on faith from a referral.
A licence check is not the same as a reputation check, so it is worth pairing it with a look at how long the agent has actually been active and how many transactions they have closed in the specific area and price range you are working in, since a clean licence and thin local experience are two different things.
Joel Dyck's licence and brokerage, Real Broker SK Ltd., are both confirmable through the same Commission register any client is welcome to check. Get your hand-reviewed valuation from Joel Dyck.
