No number in a Quebec real estate transaction generates more confusion — and more folklore — than the broker's commission. Sellers quote rates their neighbor paid in 2013. Buyers assume they pay nothing. Aggregator websites imply there is an official tariff somewhere.
Here is the actual framework, stated plainly.
The Legal Starting Point: There Is No Fixed Rate
Commission rates in Quebec are not set by law, by the OACIQ, or by any industry body. They are freely negotiated between you and your broker, and they are written into the brokerage contract before any work begins. Any suggestion that a rate is "standard," "mandatory," or "regulated" is false — the OACIQ itself is explicit that remuneration is a matter of agreement between the parties.
What you will encounter in the market are customary ranges. In the Montreal residential market, seller-side brokerage contracts commonly land somewhere between 3% and 5% of the sale price, with the percentage varying by property type, price band, scope of services, and the negotiation itself. Treat every figure in this article as a market observation, not a rule.
How the Money Actually Flows
In a typical Quebec transaction, the seller signs a brokerage contract with a listing broker and agrees to a total commission. Out of that total, the listing brokerage offers a collaboration share (the rétribution au courtier collaborateur) to the broker who brings the buyer — commonly around half of the total, and disclosed in the listing systems brokers use.
This structure explains the answer to the most common buyer question: the buyer does not usually write a commission cheque. The buyer's broker is generally paid out of the commission the seller agreed to. That does not make buyer representation "free" — the commission is embedded in the transaction economics — but it means a buyer can obtain full contractual representation without a separate out-of-pocket fee in the standard scenario. Since the 2022 reform of the Real Estate Brokerage Act, buyers working with a broker sign their own brokerage contract, which spells out exactly how that broker is remunerated, including what happens in the rare case where the seller side offers no collaboration share.
The Taxes Everyone Forgets
Commission is a taxable service. GST (5%) and QST (9.975%) apply on top of the agreed commission — an effective 14.975%. On a $500,000 sale at a 4% commission, that is $20,000 + $2,995 in taxes = $22,995 total. When you compare net proceeds between selling scenarios, run the math tax-inclusive; the seller's guide covers the full net-proceeds worksheet.
What the Commission Actually Buys
A commission is not a fee for opening doors. On a properly run sale it covers, at the listing brokerage's expense and risk:
- Pricing work — a comparative market analysis grounded in current absorption, not wishful comparables
- Preparation and staging strategy, increasingly including AI virtual staging for vacant or dated spaces
- Professional marketing — photography, video, listing copy, Centris and portal syndication, targeted digital campaigns
- Buyer-side exposure — the collaboration offer that motivates hundreds of buyer brokers to show your property
- Negotiation and transaction management — offers, counter-offers, conditions, inspection fallout, financing follow-through to the notary
Critically, the broker carries the marketing costs and is paid only if the sale closes. That contingency is priced into the rate.
The honest corollary: service levels vary enormously at identical rates. The questions that matter more than "what is your percentage" are: What is the marketing plan, specifically? What does your average days-on-market and sale-to-list ratio look like? What collaboration share will you offer, and why? A cut-rate contract that offers a weak collaboration share can quietly cost more in final price than it saves in commission — buyer brokers are professionally obligated to show suitable properties regardless, but marketing reach and momentum are not equal across listings.
Where Rates Genuinely Flex
Commission negotiations tend to move on real variables rather than goodwill:
- Price band. Higher-priced properties often support a lower percentage; the dollar amount still reflects the work.
- Dual-mandate scenarios. If the listing broker also introduces the buyer, some contracts pre-negotiate a reduced total for that case — put it in writing up front. (Since 2022, one broker cannot formally represent both parties; the buyer is then treated as an unrepresented party who receives fair treatment but not representation.)
- Repeat and multi-property relationships. An investor selling two plexes and buying a third is negotiating a relationship, not a transaction.
- Scope adjustments. Reduced-service arrangements exist, but understand precisely which services disappear before the rate does.
What it costs to exit. Standard forms provide for scenarios where remuneration is owed — including when a sale to a buyer introduced during the contract closes within a defined period after expiry. Read the remuneration clauses of the brokerage contract before signing, not after; a good broker will walk you through them unprompted.
Commission Versus the Alternative
Quebec has the most developed for-sale-by-owner ecosystem in Canada, and for some sellers — an in-demand property type, an experienced seller with time, a hot micro-market — it is a rational option. The trade is straightforward: you save the commission and take on the pricing risk, the legal exposure of the seller's declaration, the marketing spend, the availability burden, and negotiations against represented buyers.
The empirical question is whether professional representation nets more after commission than self-selling nets without it — through pricing, reach, and negotiation. That answer varies by property and by seller. What a broker owes you, under OACIQ rules, is verifiable information and honest advice — including telling you when your property is one a broker cannot meaningfully outperform the market on. If you want to test the question against your specific building, a confidential valuation is the zero-commitment way to do it.
FAQ
Is there a standard commission rate in Quebec? No. Rates are freely negotiable and set in the brokerage contract. Market practice in Montreal residential commonly falls in the 3%–5% range, but no law, regulation, or OACIQ rule fixes any rate.
Does the buyer pay commission in Quebec? In the standard scenario, no separate cheque: the buyer's broker is paid from the collaboration share of the commission the seller agreed to. The buyer's own brokerage contract specifies remuneration and covers edge cases where no collaboration share is offered.
Are commissions taxable? Yes — GST 5% plus QST 9.975% apply to the commission, an effective 14.975% on top of the agreed amount. Budget it in your net-proceeds calculation.
Can I negotiate the commission after signing the brokerage contract? The contract governs once signed; amendments require mutual agreement in writing. Negotiate scope, rate, collaboration share, and duration before signing — and ask how each is justified.
Do I owe commission if my house doesn't sell? Under the standard exclusive contract, remuneration is generally owed on a completed sale. Read the specific remuneration clauses — including post-expiry provisions for buyers introduced during the mandate — before signing.
