Realtor.ca vs MLS

Realtor.ca is not the MLS. It is a public advertising portal — operated by CREA, the national association — that displays listings syndicated to it from member boards. “The MLS” is something else: each board’s member database of record, where listings are actually entered, updated, and cooperated on. The portal shows a public slice of those systems; the systems themselves hold more data, update faster, and include records that never reach the portal at all. Once that distinction is clear, most of the confusion around it — missing listings, stale statuses, “my agent sees things I can’t” — resolves on its own.

Two different things wearing one acronym

An MLS is a cooperation system: a board’s members enter listings into a shared database under shared rules of cooperation with other members, and that database becomes the market’s working record. It is member infrastructure — rich, fast, and access-controlled. Realtor.ca sits downstream. Boards syndicate a defined public subset of their MLS content to CREA’s portal through its national distribution framework — DDF — and the portal advertises it to the public under consumer-display rules. One is the factory; the other is the storefront window. Calling the window “the MLS” is the shorthand that produces almost every misunderstanding in this area.

What the member system has that the portal doesn’t

Three layers, concretely. More fields per listing — the member record carries data the public display omits, from cooperation details to remarks written for other agents rather than for the public. Faster clocks — a status change exists in the member system the moment it’s entered, while public surfaces update on syndication schedules; in a market where a good listing goes firm in days, hours of lag are the difference between a showing booked and a disappointment explained. Records that never syndicate — some listings aren’t distributed to the portal at all, and the entire sold-and-history layer is absent from it, because sold data is non-public under board rules and reaches consumers only through gated channels such as a brokerage’s VOW website. When a buyer says “my agent found something that wasn’t on realtor.ca,” this is the machinery behind the sentence.

Where agent websites fit between them

A member brokerage’s website can sit closer to the MLS than the national portal does, which surprises consumers and shouldn’t. Boards license defined slices of MLS data to member sites — the IDX lane for public active listings, the VOW lane for the registered sold-data layer — and the MLS-vs-IDX line defines exactly what each covers. A well-built board-fed site refreshes on a feed measured in minutes, carries the fields its licence permits, and can offer registered visitors the sold history the portal cannot show at all. The full pipeline comparison — why a board-fed site and realtor.ca genuinely differ in scope, clock, and fields — is at why is my website different from realtor.ca.

Why the distinction is worth having ready

For client conversations, mostly. “Is it on MLS?” usually means “is it on realtor.ca?”, and the accurate answer — it’s in the board system, and here’s what that means for what you can and can’t see — is a small, checkable demonstration of competence. The same clarity defuses the awkward cousin question, “why did that house show up on the portal after it sold?”, which is almost always a syndication clock, not a conspiracy. It also frames your own web presence correctly: your site isn’t competing with the portal to be the national window; it’s offering your market’s slice of the member system, fresher and deeper than the window, on a domain where the researcher is your prospect rather than the portal’s. The portal advertises the market. The MLS runs it. Knowing which one you’re pointing at is the whole answer.
