Cooperating commission

Cooperating commission is the share of the listing commission that the seller’s brokerage offers to whichever brokerage brings the buyer — the “cooperating” brokerage, in board vocabulary. The seller agrees a total commission in the listing agreement; the listing brokerage publishes an offer of part of it on the MLS system; and a buyer’s brokerage that closes the deal collects that offer. It is the financial plumbing that has historically let buyers be represented without writing their agent a cheque directly.
How the money moves
At closing, the commission comes out of the seller’s proceeds to the listing brokerage, which then pays the cooperating brokerage its offered share. Each agent is paid by their own brokerage under their own split — the same through-the-brokerage rule that governs a referral fee governs here. The offer is a term between brokerages, made through the board’s system, which is why it binds even though the buyer’s brokerage never signed the listing agreement.
Where the buyer agreement fits
The co-op offer answers how the buyer’s brokerage gets paid; the buyer representation agreement answers what it is owed. Ontario’s TRESA-era agreements state the buyer brokerage’s fee explicitly, and the standard mechanics credit the cooperating commission against it. When the offer covers the fee, the buyer pays nothing out of pocket. When it doesn’t — a thin offer, or a mere posting offering little or nothing — the shortfall can land on the buyer, which is why the fee clause deserves an unhurried read before anyone tours a house.
The transparency era
Commission structures spent 2024 in the headlines. In the United States, litigation settlements forced offers of compensation off MLS systems entirely, rewiring how buyer’s agents get paid there. Canada has not followed: offers of cooperating commission still ride Canadian MLS systems, though the model is under active scrutiny from the Competition Bureau and the courts, and disclosure expectations have tightened — buyers increasingly see the numbers rather than assuming them. For agents, the practical posture is straightforward: know what the offer is on every listing you show, disclose what your agreement requires, and never present the co-op share as some fixed law of nature. It is an offer, deal by deal, and it always was.
Frequently asked questions
Who actually pays the buyer's agent?
In the common case, the seller's proceeds fund it: the listing brokerage collects the full commission at closing and pays the cooperating brokerage its offered share. But the buyer's representation agreement is the governing document — if the co-op offer falls short of the fee it sets, the buyer can owe the difference.
Can the cooperating commission be zero?
Yes. Nothing forces a listing brokerage to offer a meaningful share, and mere postings in particular may carry a nominal or zero offer. A buyer's agent checks the offer before showing; a buyer should understand what their representation agreement says happens when the offer doesn't cover the fee.
