Real Estate Listing Agreements in Ontario

A listing agreement is the contract that gets a property-sale process started in Ontario — but it isn’t the contract most people picture when they think about buying or selling a home. Rather than being between a seller and a buyer, a listing agreement is between the seller and a real estate brokerage, authorizing that brokerage (and the salesperson acting under it) to market the property and work toward a sale in exchange for a commission.

This is a distinct, earlier contract from the agreement of purchase and sale that eventually gets signed once a buyer’s offer is accepted. Because the listing agreement sets the financial and practical terms of the entire sale process — commission, marketing, timeline — it’s generally worth reading as carefully as any other contract, even though it’s often signed early and sometimes treated as a formality.

A listing agreement is generally in writing, as most provincial standards and brokerage practice require, and it typically names the property, the seller, and the brokerage, sets the asking price, and spells out the scope of services the brokerage will provide — marketing, showings, negotiation support, and coordinating with buyers’ brokerages, among other things. It also typically authorizes the brokerage to collect and share certain information about the property, including publishing it on the Multiple Listing Service, as discussed further below.

Commission is usually the term sellers focus on most, and for good reason — it directly affects the net proceeds from a sale. In Ontario, commission rates are not fixed by law, regulation, or any industry association; they’re individually negotiated between the seller and the brokerage for each listing. Rates are commonly expressed as a percentage of the final sale price and are frequently structured to be split between the listing brokerage and a separate buyer’s brokerage, though the precise split and structure varies from agreement to agreement.

Commission is generally payable on a completed sale, meaning it typically becomes owed once the transaction closes rather than simply when an offer is accepted. Some agreements also address what happens if a sale falls through after an accepted offer — for example, due to a failure to close — which is one more reason the commission clause is worth reading in full rather than skimming the headline percentage.

A listing agreement generally runs for a fixed term — commonly a number of weeks or months — after which it expires unless the parties agree to extend or re-list. The length is negotiated, and sellers sometimes choose a shorter initial term to test a brokerage’s performance before committing to something longer, while others prefer a longer term that gives more time for the market to respond.

One of the more commonly misunderstood provisions is the holdover period, sometimes called holdover protection. This clause can entitle the brokerage to its commission even after the listing agreement has technically ended, if the eventual buyer was someone the brokerage introduced to the property during the listing term. It’s generally designed to prevent a seller from simply waiting for the listing to expire and then completing a sale directly with a buyer the brokerage already found and introduced — but the specific length of the holdover period, and exactly what counts as an “introduction,” depends entirely on how the clause is worded.

Most residential listing agreements in Ontario are structured so that one brokerage has the exclusive right to market and sell the property, often combined with publishing the listing on the Multiple Listing Service (MLS) system, which gives other brokerages and their buyers access to the listing. This combination is generally chosen because it maximizes exposure to the broadest possible pool of buyers.

Exclusive, non-MLS listings also exist, generally for sellers who prefer a more private sale process or who are marketing to a narrower, pre-identified group of buyers. Other arrangements — like open listings, where more than one brokerage could technically earn a commission — are less common in typical residential resale transactions but can come up in specific situations. Understanding exactly which structure a particular agreement creates matters because it affects who can market the property and under what terms.

Ontario’s Trust in Real Estate Services Act, 2002 (TRESA) is the legislation that now governs how real estate brokerages and salespersons must conduct themselves, having replaced the earlier Real Estate and Business Brokers Act, 2002 framework. TRESA generally sets out requirements around disclosure, conduct standards, record-keeping, and how representation agreements — including listing agreements — are expected to be handled.

For sellers, the practical effect is that a listing agreement doesn’t exist in a vacuum — it operates within a regulatory structure designed to set minimum standards for how brokerages deal with clients. This generally includes obligations around explaining the agreement’s terms, the type of representation being offered, and how conflicts of interest (like multiple representation on the same transaction) are disclosed and handled.

TRESA also generally requires brokerages to use agreements and forms that meet certain content standards, and it sets out rules around advertising, the use of a seller’s information, and how a brokerage must behave when representing both the seller and a buyer in the same transaction. Sellers signing a listing agreement are generally entitled to have these aspects explained before signing, rather than discovering them only once a dispute arises.

Because a listing agreement is a binding contract for a fixed term, most agreements don’t give the seller an automatic, unilateral right to cancel before that term ends. An early release is generally something the seller has to request, and the brokerage has to agree to — sometimes subject to conditions like reimbursing marketing costs already incurred or preserving a holdover period for buyers already introduced to the property.

At the other end of the term, most listing agreements simply expire rather than automatically renewing, leaving the seller free to re-list with the same brokerage, switch brokerages, or pause the sale process altogether — subject again to whatever holdover protection remains in effect from the prior listing. Sellers considering a change in brokerage partway through a sale process generally find it useful to review both the term and holdover provisions of the existing agreement first, since those terms don’t simply disappear the moment a new agreement is signed elsewhere. For more on how Ontario real estate contracts generally work once an offer is in place, see our guides on conditions in an APS and real estate disclosure obligations.

Once a listing agreement is in place and the property is being marketed, the next major contract in the process is the agreement of purchase and sale signed with an actual buyer. The listing agreement doesn’t disappear at that point — its commission and holdover terms generally continue to apply to that sale, and the seller is typically still bound by whatever the listing agreement says about the brokerage’s entitlement once the transaction closes.

Sellers sometimes assume that once an offer is accepted, the listing agreement’s terms become irrelevant, but the two documents generally operate together rather than one replacing the other. For example, how a deposit is handled, or what happens if a buyer and seller later agree to amend or walk away from an accepted offer, can still intersect with commission obligations created under the original listing agreement. Keeping both documents in mind — rather than treating the listing agreement as settled business once an offer comes in — is generally a more complete way to understand a seller’s overall contractual picture.
