Selling a $1.2 million GTA home can put $60,000 or more in commission and sales tax on the closing statement. That is why homeowners asking how much commission to sell house Ontario should look beyond a single advertised percentage. The real number depends on your listing agreement, the compensation offered to the buyer’s brokerage, HST, and whether your agent provides a rebate.
The good news: commission is negotiable. You can protect more of your hard-earned equity without giving up the pricing strategy, exposure, negotiation, and transaction support that help produce a strong sale.
How Much Commission to Sell a House in Ontario?
There is no government-set real estate commission rate in Ontario. Many full-service GTA listings have traditionally offered a total commission near 4% to 5% of the sale price, plus 13% HST on the commission. That total is commonly divided between the listing brokerage and the brokerage representing the buyer.
A common example is 2.5% for the listing side and 2.5% for the buyer’s brokerage. But that is a market convention, not a rule. A seller may negotiate a lower listing-side fee while continuing to offer competitive buyer-broker compensation. The exact split should be written clearly in your listing agreement before your property is listed.
Here is what the math can look like on a $1,000,000 sale:
- At 5% total commission, the commission is $50,000. HST is $6,500, for a total commission-related cost of $56,500.
- At 4% total commission, the commission is $40,000. HST is $5,200, for a total of $45,200.
- At 3.5% total commission, the commission is $35,000. HST is $4,550, for a total of $39,550.
That difference is not small. Moving from 5% to 3.5% on a $1 million home preserves $16,950 after HST. That money can reduce your next mortgage, pay for a renovation, strengthen your emergency fund, or simply stay with your family rather than leave your equity at closing.
Understand the Two Parts of Commission
Sellers often hear one percentage and assume it all goes to their listing agent. In most transactions, there are two separate compensation components.
The listing-side commission pays for the work of preparing, pricing, launching, marketing, managing, negotiating, and closing the sale. The buyer-broker commission is the amount the seller agrees to offer the brokerage that brings the successful buyer. Both amounts are typically paid from the seller’s proceeds through the lawyer on closing.
This distinction matters because a lower listing commission does not automatically mean a lower total commission. For example, a brokerage may charge 1% to list your property while the seller offers 2.5% to the buyer’s brokerage. The total commission is then 3.5%, plus HST.
It also helps you compare proposals fairly. Ask every agent to show the listing-side fee, buyer-broker fee, total commission, HST, and any rebate separately. A clear breakdown avoids surprises when you review the closing figures.
HST Is Part of Your Real Selling Cost
In Ontario, HST applies to real estate commissions. It does not apply to the full sale price of a resale home, but it does apply to the commission charged by the brokerages.
That means a quoted 5% commission is not your final cost. On a $900,000 sale, 5% commission equals $45,000, and the 13% HST adds $5,850. Your actual commission-related expense is $50,850.
When comparing rates, always compare the after-tax total. A difference that looks like half a percent before HST becomes a larger dollar amount once tax is included, especially in Toronto, Markham, Richmond Hill, Vaughan, Mississauga, and other GTA markets where sale prices can be substantial.
A Full-Service Rebate Can Change the Equation
A commission rebate is different from a bare-bones listing service. The right model gives you a measurable financial benefit while preserving the services that make a listing competitive.
For sellers, The Cashback Team offers a 0.5% rebate that reduces the effective listing commission to 1%, while providing full REALTOR® representation. Depending on the agreed buyer-broker commission, that can create meaningful savings without treating your sale like a do-it-yourself project.
Consider a $1,250,000 home. If the listing-side commission is effectively 1% rather than 2.5%, the pre-tax difference on the listing side is $18,750. Even after accounting for HST, the savings can be significant. Your exact total will still depend on the buyer-broker compensation you choose to offer and the terms of your signed agreement.
The value is not just the percentage. A full-service sale should include professional photography, video, staging guidance, MLS exposure, targeted marketing, private showings, offer management, negotiation, paperwork coordination, and support through inspection, financing, and closing. Saving on commission should not mean losing the work that protects the sale price.
Lower Commission Is Not the Only Number That Matters
The cheapest option is not always the best financial outcome. If a weak launch, poor presentation, limited marketing, or poor negotiation costs you more on price than you saved on commission, the lower fee was not a win.
A better question is: what service level and strategy will help me achieve the strongest net proceeds? Net proceeds are what remain after commission, HST, mortgage payout, legal costs, and other closing adjustments. A skilled listing strategy can matter greatly in a fast-moving market, a slower neighborhood, or a home that needs careful positioning.
For example, a seller choosing between two agents should not compare only 1% versus 2.5%. They should ask how each agent will price the home, prepare it for market, reach qualified buyers, handle competing offers, and negotiate inspection or financing issues. The goal is to lower avoidable costs while maintaining serious representation at every step.
Questions to Ask Before You Sign a Listing Agreement
Before committing, ask for a written commission breakdown and make sure you understand when it is payable. Your agent should answer direct questions without vague language.
Ask what percentage is for the listing brokerage, what percentage is being offered to the buyer’s brokerage, and whether HST is included or added. Ask whether the agreement contains an early-cancellation fee, an extension clause, or a holdover period that could create commission obligations after the listing expires.
You should also ask exactly what marketing is included. Does the fee cover professional photography, video, staging consultation, MLS listing, social media promotion, open houses where appropriate, and ongoing communication? If a rebate is offered, ask how and when it is paid, and ensure it is documented in the agreement.
Finally, discuss buyer-broker compensation strategically. It should fit your property, local market conditions, and selling goals. The answer is not automatically the highest or lowest possible number. It is the number that supports a competitive sale while keeping your net proceeds in focus.
Commission Is Only One Closing Cost
Real estate commission is usually the largest selling expense, but it is not the only one. Ontario sellers may also have legal fees and disbursements, mortgage discharge fees, prepayment penalties if they break a mortgage, and adjustments for property taxes or utilities. If the property is an investment or has been rented, tax implications may also deserve a conversation with a qualified tax professional.
Ask for a seller net-sheet estimate before listing. It should show a realistic projected sale price, total commission, HST, mortgage payout, estimated legal costs, and likely adjustments. Seeing the full picture early lets you decide what price and terms make your move work financially.
A home sale should fund your next chapter, not quietly drain it through unclear fees. Get the commission details in writing, compare the after-tax numbers, and choose representation that works as hard to protect your equity as it does to sell your home.
