Advertise another brokerage's listing

The short answer: not without permission — with one giant, deliberately-built exception. Ad-hoc advertising of a listing you don’t hold (social posts, paid ads, flyers, featured spots) requires the listing brokerage’s consent, in writing, everywhere in Canada. But displaying other brokerages’ listings on your website through your board’s IDX or reciprocity framework is not only allowed, it is the entire point of those programs. Confusing the two lanes is how agents end up in either a compliance complaint or an unnecessary panic. Here is where the line runs.

The sanctioned lane: your website’s board feed

MLS® cooperation systems exist so members can market each other’s inventory: an IDX website in Ontario, or a reciprocity site in the Vancouver market, displays participating brokerages’ active listings under rules the boards wrote — attribution to the listing brokerage on every card, current data, prescribed logos and disclaimers where required. Consent is structural: brokerages participate in the system knowing display rights come with it, and sellers sign listing agreements that say so. On this lane you don’t ask permission listing-by-listing; you comply with the display rules that are the permission.

Everything else: consent first

Lift a listing out of that framework — a boosted post, “check out this stunning new listing” with photos, a paid campaign built around a specific property — and you’re advertising another brokerage’s listing in the prohibited sense unless they said yes. Regulators are aligned on the baseline: in Ontario, advertising a listing that isn’t yours requires the listing brokerage’s written consent, and B.C.‘s advertising rules reach the same place through the prohibition on false or misleading advertising plus the boards’ own rules. Two separate rights are in play, and people forget the second: the brokerage’s marketing rights over the listing, and the photographer’s copyright in the photos — which the listing brokerage itself may not be able to sublicense to you.

The real offence: implying it’s yours

Run the violations backward and they share one engine: misrepresentation. An ad that leaves a consumer believing you hold the listing — or that inquiries reach the listing agent when they reach your lead form — is misleading advertising even where some technical display right existed. This is the lens that resolves edge cases better than any rule list: would a reasonable consumer, seeing this ad, misunderstand who represents the seller? Your IDX page, with its attribution rendered honestly, passes. A cropped screenshot with your headshot and phone number over it does not. The same logic covers omission: keeping a listing in your marketing after it terminates or sells, or presenting stale data as current, misleads just as effectively as a false byline — currency is part of the display right, not a courtesy. The general identification obligations in RECO’s advertising rules compound this: your own name and brokerage must be present and accurate in everything, on top of the listing brokerage’s credit.

Practical playbook

Wanting to promote inventory you don’t hold usually has a clean route. To feature a colleague’s listing socially: ask the listing agent, get consent in writing, credit as agreed, and use imagery you’re licensed to use. To advertise inventory generally: point paid traffic at your website’s search and area pages, where every listing renders inside the compliant framework — this is the model where advertising spend builds your asset instead of borrowing someone else’s. To serve a buyer watching a specific hot property: your site’s own listing page for it is shareable by design. And if your market spans systems, the display-rights question compounds across them — covered in displaying listings from multiple boards. When in doubt, the two-question test: do I have display rights here, and could anyone mistake whose listing this is? Clear answers to both, in that order, keep you off the complaints docket.
