Broker Commission in Quebec: The Base It Is Calculated On, and How It Splits

This article is not about the rate, which is negotiable, but about three mechanisms that decide what you actually pay: the calculation base, the split, and the moment of deduction. On the contract that frames all of it, see our read of exclusive versus non-exclusive listing agreements.

The base is the sale price, never your net proceeds

This is the most common arithmetic error, and it happens mentally, with nobody acting in bad faith.

The percentage agreed in the brokerage contract applies to the price the property sells for. Not the price less the mortgage balance, not accumulated equity, not what will be left after costs. The price, in full.

The gap between the two calculations grows with debt. A seller whose mortgage represents a large share of the property's value has modest equity, and applying the percentage to that equity produces a number with no relation to the remuneration owed. The amount owed does not depend on their level of debt at all.

The practical consequence is simple: always compute on the price, and do it before listing rather than while reading the notary's statement of disbursements.

No rate is imposed, and "standard" is not "regulated"

Remuneration is agreed between the seller and the agency, in the brokerage contract. It is negotiable: the rate, the calculation base, and the payment terms.

What is regulated in Quebec is the form of the contract and the broker's duty to inform, not the amount of their remuneration. No rate is prescribed, none is prohibited.

When a rate is presented to you as the usual market rate, you are being described a practice, and a practice can be discussed. That does not mean you should negotiate for its own sake: the next section explains exactly why a badly aimed negotiation costs more than it returns.

The split happens in two steps, not one

This is the invisible part of the mechanism, and it explains almost everything else.

Step one, between agencies. When the buyer arrives through another broker, the remuneration divides between the agency holding your brokerage contract and the collaborating broker's agency, according to the offer of collaboration.

Step two, inside each agency. Each agency then shares with its own broker under their internal arrangement, which does not concern you and which you do not need to know.

What to take from this: the broker sitting across from you does not receive the percentage written in the contract. They receive a fraction of a fraction. That is not an argument against negotiating, it is the information you need to negotiate the right thing.

Why a lower rate is not always cheaper

Here is the mechanism almost nobody explains, and the only one in this article that can cost you money without ever appearing on a document.

In most structures, reducing the total also reduces the share offered to the collaborating broker. That share weighs when a buyer's broker assembles a list of properties to show. This is not bad faith: at equal time and comparable files, remuneration enters the trade-off, as it does in any commission-based occupation.

A saving on the rate can therefore be paid for in showings that never happen. And a property that gets fewer showings sells more slowly, or sells at the price that a thin flow of offers allows. The cost of one extra month on market plus a negotiation from a weak position easily exceeds the saving on the percentage.

So the useful question is not "what is the total", but "what does this total leave to the buyer's side". It is asked directly, before signing, and the answer sits in the offer of collaboration.

Payment happens at the notary, out of the proceeds

A seller writes no cheque and pays nothing in advance. The remuneration is deducted from the sale proceeds when ownership transfers, and remitted to the agency.

That is why the item does not appear on an invoice but on the statement of disbursements the notary sends before closing. That document is the only reliable figure for your transaction, because it reflects the price actually obtained and the applicable taxes.

Two points that change a budget. Applicable sales taxes are added to the remuneration, which pays for a service: budgeting the percentage alone omits part of the cost. And the deduction comes out of the proceeds, so it reduces what you receive, which matters if those proceeds were to serve as the down payment on your next purchase.

Four questions to ask before signing

On exactly what base the percentage is computed, and which taxes are added. The answer belongs in the contract, not in a conversation.

What share is offered to the collaborating broker. This is the most useful question on the list, and the least often asked.

In which cases the remuneration remains owed if the sale does not close through your broker. That question belongs to the type of agreement, and our article on exclusive versus non-exclusive contracts answers it in detail.

And finally: what the service concretely includes, since that is what the remuneration buys. Two proposals at the same rate do not necessarily deliver the same marketing, and two proposals at different rates may deliver the same. Comparing percentages without comparing what they buy is the only real trap in this negotiation.
