What does it cost to sell a house in Markham?
Selling costs in Ontario commonly total 3% to 6% of the sale price. The largest items are commission, which is fully negotiable with no standard or legislated rate in Ontario, and 13% HST on that commission, which the seller pays. Legal fees are commonly quoted between $800 and $2,000 plus disbursements. A mortgage discharge costs roughly $260 to $340 at the major lenders plus an $80.50 Ontario registration fee. A condominium status certificate is capped by regulation at $100 including tax. The seller pays no land transfer tax in Ontario, and Markham has no municipal land transfer tax. The biggest avoidable surprise is a mortgage prepayment penalty, which on a fixed-rate mortgage can run into five figures.

Michael John Lau, a REALTOR® with the Kaizen Real Estate Team, one of the most active real estate teams in Markham and York Region, walks sellers through this at the listing conversation rather than at closing, because two of these items can be reduced or avoided entirely if they are known about early.
Commission: The Part Everyone Asks About
The most important fact is the one least often stated plainly.
Real estate commissions in Ontario are fully negotiable. There is no standard rate, no legislated rate and no board-mandated rate. Any claim that "5% is standard" is marketing language, not law.
Observed market practice in Ontario has run roughly 3.5% to 5% combined, commonly structured with a portion to the buyer's brokerage and a portion to the listing brokerage. Those are observations about what has been happening, not a rate card and not a recommendation.
One rule does bind. Under CREA's MLS® rules, a listing brokerage must offer cooperating compensation to the buyer's brokerage, and that amount can be any amount except zero. CREA confirmed in October 2025 that this rule remains in effect. The amount is negotiable; offering literally nothing through the MLS System is not permitted under that rule.
What has not changed
The United States NAR settlement did not change Canadian rules. CREA has stated there are different legal and factual circumstances between the Canadian litigation and the American matter, and confirmed its cooperating compensation rule unchanged. Do not assume American headlines about buyer agreements or MLS compensation display apply here.
What is live in Canada is litigation and regulatory attention. The Competition Bureau has an ongoing investigation into CREA's commission rules, expanded in February 2026 to include a British Columbia board. The Bureau has made no finding of wrongdoing and the matter is ongoing. Separately, a class action proceeding in Federal Court saw one national brokerage settle for $7.8 million in October 2025, without any admission of wrongdoing, with litigation continuing against others.
The HST detail that surprises sellers
A resale home carries no HST on its purchase price. The brokerage service, however, is a taxable supply, so 13% HST applies to the commission and the seller pays it.
On a $20,000 commission that is $2,600, for a total of $22,600. A seller of a personal-use resale home cannot recover it.
The Mortgage Penalty: The Big One
This is the cost that most often derails a seller's arithmetic, and it is entirely knowable in advance.
- Variable-rate mortgage: the penalty is generally three months' interest on the outstanding balance.
- Fixed-rate mortgage: the penalty is generally the greater of three months' interest or the Interest Rate Differential.
How the interest rate differential works
- Identify the time remaining in your term.
- The lender compares your contract rate against its current rate for a comparable remaining term.
- The difference is applied to your outstanding balance for the remaining term.
- That figure is compared to three months' interest, and the lender charges the higher.
There is no single standard IRD formula across Canadian lenders. Some use posted rates, some use discounted rates, some use proprietary methods. Two identical mortgages at two different lenders can produce materially different penalties.
Michael John Lau's recommendation is specific and it takes one phone call: get the penalty quoted in writing by your lender before you list. Ask at the same time whether the mortgage can be ported to your next property, which can avoid the penalty entirely.
Adjustments at Closing
These can run in either direction and are calculated by your lawyer on the statement of adjustments. A fuller breakdown sits on the closing costs page.
- Property taxes are prorated to the closing date. If you prepaid beyond closing, the buyer credits you. If you are behind, you credit the buyer.
- Condominium common element fees are billed monthly in advance, so a mid-month closing usually produces a credit to the seller.
- Utilities prepaid beyond closing are adjusted.
- Rental property: rent collected in advance is adjusted, and last month's rent deposits must be handed over.
- Fuel oil remaining in a tank is adjustable, which matters on some older and rural properties.
Two Situations With Much Larger Costs
If you are a non-resident of Canada
This changes the timeline as well as the cost. A non-resident disposing of Canadian real property must obtain a Certificate of Compliance from the Canada Revenue Agency, with notification required within 10 days of the disposition.
Until the certificate is produced, the buyer's lawyer holds back 25% of the proceeds for ordinary capital property. A 50% rate can apply where the property is depreciable taxable Canadian property, such as a rental where capital cost allowance has been claimed, or property held as inventory.
CRA processing takes months. This is the single most common reason a non-resident seller does not receive their money on closing day. Anyone in this position should engage a cross-border accountant before listing, not after an offer.
If the property is not your principal residence for every year you owned it
- The capital gains inclusion rate is 50% for 2026. The proposed increase to two-thirds was cancelled in March 2025. Ignore any source still quoting 66.67%.
- Only one property per family unit per year can be designated as a principal residence.
- You must report the sale even when the exemption fully shelters the gain. Since 2016 the disposition goes on Schedule 3, with Form T2091 required where the property was not your principal residence for every year of ownership. The penalty for a late designation can reach $8,000.
- The residential property flipping rule treats a property sold within 365 days of purchase as business income rather than a capital gain, and the principal residence exemption does not apply.
A Worked Example
An illustration only, on a home selling at Markham's August 2026 all-types average of $1,208,692, assuming a negotiated commission of 4%:
| Item | Amount |
|---|---|
| Commission at 4% | $48,348 |
| HST at 13% on commission | $6,285 |
| Legal fees | $1,400 |
| Mortgage discharge fee | $300 |
| Discharge registration | $80.50 |
| Staging and photography | $2,500 |
| Approximate total | $58,914, or about 4.9% of the sale price |
This excludes any mortgage prepayment penalty, adjustments, repairs and moving costs. To run it on your own home, start with a free home evaluation, and use the mortgage calculator for the financing side. The 4% commission figure is used purely to make the arithmetic visible and is not a quoted rate. Commission is negotiated between a seller and a brokerage in every transaction.

Frequently Asked Questions
What does it cost to sell a house in Markham?
Commonly 3% to 6% of the sale price. The main items are commission, 13% HST on that commission, legal fees of roughly $800 to $2,000, a mortgage discharge of about $260 to $340 plus $80.50 registration, and any prepayment penalty.
Is there a standard real estate commission in Ontario?
No. Commissions are fully negotiable and there is no standard, legislated or board-mandated rate. Observed market practice has run roughly 3.5% to 5% combined, which describes what has been happening rather than setting a rate.
Do I pay HST when I sell my house?
Not on the house itself, which is exempt on a resale. You do pay 13% HST on the brokerage commission, because the service is a taxable supply. A seller of a personal-use home cannot recover it.
Does the seller pay land transfer tax in Ontario?
No. The buyer pays it. Markham also has no municipal land transfer tax, so a Markham buyer pays only the provincial amount. Toronto is currently the only Ontario municipality with its own.
How much is a mortgage prepayment penalty?
On a variable-rate mortgage, generally three months' interest. On a fixed-rate mortgage, generally the greater of three months' interest or the interest rate differential, which can reach five figures. There is no single standard IRD formula across lenders, so get the figure in writing from your own lender before listing.
How much does a status certificate cost?
A maximum of $100 including all applicable taxes, set by regulation under Ontario's Condominium Act. The corporation must provide it within 10 days. Higher amounts quoted in the market are typically rush or expedite service charges rather than the certificate fee.
