A sale price can look excellent on paper, then feel very different once the final statement of adjustments arrives. For homeowners, understanding seller closing costs in Ontario before listing is the practical way to avoid surprises, compare offers properly, and know what you will actually take home.
The good news is that most selling costs are predictable. The bigger issue is that they are often discussed separately – commission, HST, legal work, mortgage payout – rather than as one clear net-proceeds picture. A proper selling strategy starts with both numbers: what your home could sell for and what you keep after the transaction closes.
The main seller closing costs in Ontario
For a typical resale home in Toronto, the GTA, or Southern Ontario, the largest deduction is usually real estate commission. Legal fees and mortgage-related charges tend to be smaller, but they still need to be included in your budget. Depending on your situation, adjustments, repair commitments, and tax considerations can also affect your final proceeds.
Real estate commission and HST
Commission is generally the largest selling expense. There is no government-set commission rate in Ontario. It is negotiable, and the structure should be clear before you sign a listing agreement.
A full-service sale commonly includes compensation for the listing brokerage and, where applicable, the brokerage representing the buyer. This is not a detail to gloss over. The buyer-agent commission offered can influence how your property is positioned to the market and how broadly it is shown through the established brokerage network.
HST is charged on real estate commission. At Ontario’s 13% HST rate, a $20,000 commission becomes $22,600. Sellers sometimes remember the advertised commission percentage but forget to add HST when estimating their proceeds.
The commission model matters most when your equity is on the line. On a $1,000,000 sale, even a one-percentage-point difference in commission is $10,000 before HST. That is why a lower listing commission is not just a marketing claim – it can be a meaningful part of your financial plan, provided the service still includes strong pricing advice, property preparation, professional marketing, negotiation, and transaction management. One Percentage Guys is built around that full-service 1% listing commission approach.
Before listing, ask for a written breakdown showing the listing side, the buyer-brokerage component, HST, and any extra charges. A lower headline rate is only useful if you understand the complete structure behind it.
Legal fees and disbursements
You need a real estate lawyer to complete the sale. Your lawyer prepares and reviews closing documents, receives sale funds, pays out the mortgage and registered claims, handles the transfer process, and sends the remaining proceeds to you.
Legal fees for a straightforward Ontario resale are often in the hundreds to low thousands once disbursements and HST are included. The exact amount varies based on the law firm and the complexity of the file. A condominium sale, a private mortgage, an estate sale, a separation, a power of sale, or title issues can require additional work.
Disbursements are third-party expenses the lawyer pays or incurs to close the transaction. They can include courier charges, document registration searches, bank wire fees, tax certificates, and mortgage payout administration. Ask for an all-in estimate rather than focusing only on the legal fee quoted at the start.
Mortgage discharge and prepayment charges
If you still have a mortgage, it must usually be paid out on closing. Your lawyer will request a payout statement from the lender, which sets out the exact amount required to clear the loan on the closing date.
There may be a mortgage discharge or registration fee. More significantly, you may face a prepayment penalty if you are ending a closed mortgage before its term expires. Depending on the mortgage product, the penalty may be calculated as three months’ interest or an interest rate differential. On some mortgages, especially older or fixed-rate loans, the interest rate differential can be substantial.
Do not rely on a rough estimate from last year. Request an up-to-date payout quote from your lender before you list, then review it again once you have a firm closing date. Also ask whether your mortgage is portable if you are buying another home. Porting can reduce or avoid a penalty in some cases, but it depends on your lender’s rules, timing, and the new mortgage you qualify for.
Property tax, utilities, and condominium adjustments
At closing, expenses tied to the property are adjusted between buyer and seller. The goal is simple: each party pays its fair share for the period they own the home.
If you prepaid property taxes beyond the closing date, the buyer may reimburse you through the statement of adjustments. If taxes are unpaid for a period when you owned the property, your share is deducted from the sale proceeds. Water and utility accounts should also be checked and closed or transferred according to the provider’s process.
For condominiums, the statement of adjustments can include prepaid common expenses, special assessments, or other amounts owed to the condominium corporation. If a special assessment has been approved before closing, who pays it can become a negotiated term in the agreement of purchase and sale. The answer is not always automatic, so clarity in the offer matters.
These adjustments are often not large compared with commission or a mortgage penalty, but they can change your final number by hundreds or thousands of dollars. Your lawyer will calculate them, but you should know they are coming.
Costs that are not technically closing costs – but still reduce your net proceeds
Some expenses happen before closing rather than on closing day. They should still be part of your selling budget because they affect what you retain from the sale.
Preparing a property for market may involve cleaning, painting, minor repairs, staging, photography, moving, storage, landscaping, or a pre-listing home inspection. Not every home needs every service. A well-maintained downtown condo may need a different preparation plan than a detached family home in Oakville or Brampton.
The key is to spend strategically. Replacing a visibly worn light fixture, repainting a high-traffic hallway, or addressing a known leak may protect buyer confidence and support a stronger offer. Over-improving a home just before sale, however, does not always produce a matching return. Your listing strategy should separate the work that makes a measurable difference from the work that simply adds cost.
If you agree to repair an issue after a home inspection, provide a buyer credit, or accept a lower price to resolve a condition, that is also a real reduction in your proceeds. It may not appear as a line called “closing cost,” but it belongs in the same financial conversation.
Taxes sellers should not overlook
Most Canadians do not pay capital gains tax when selling a home that qualifies as their principal residence for every year they owned it. You still generally need to report the disposition on your tax return, even if the principal residence exemption eliminates the taxable gain.
The picture changes if the property was a rental, a cottage, an investment property, or only partially designated as your principal residence. A change in use, such as renting out a former home, can create additional tax considerations. Selling a newly built or substantially renovated home can also raise HST issues in certain circumstances.
Non-resident sellers face another important process. A purchaser may be required to withhold part of the sale proceeds unless the seller obtains the appropriate clearance documentation from the Canada Revenue Agency. This is not a routine cost for most Ontario sellers, but it can materially affect the funds available on closing and should be addressed early with legal and tax professionals.
A real estate agent can help you identify questions to raise, but legal and tax advice should come from qualified professionals who can review your specific circumstances.
How to estimate your net proceeds before you accept an offer
The sale price is only the first number. To estimate what you will receive, start with the expected sale price and subtract the commission plus HST, your estimated legal fees and disbursements, the mortgage payout and any penalty, outstanding property-related amounts, and your expected preparation costs.
Then account for adjustments. If you have prepaid taxes or condo fees, you may receive credits. If you owe amounts that relate to your ownership period, those will reduce the balance. Your lawyer’s final statement will be the authoritative figure, but a conservative estimate before listing helps you make better decisions.
For example, a seller who accepts $1,050,000 instead of holding out for $1,070,000 may still be making the stronger financial decision if the earlier offer has no sale-of-property condition, a better closing date, fewer repair risks, and lower carrying costs. The best offer is not always the highest headline price. It is the offer with the strongest net result and the right level of certainty.
Questions to ask before listing
A transparent plan should answer a few direct questions: What is the total commission structure, including HST? What will it cost to discharge or break the mortgage? Are there condo fees, tax arrears, or assessments to address? What preparation work is worth doing before launch? And based on a realistic selling range, what is the likely net amount available for your next move?
Getting those answers before you go to market gives you room to negotiate from a position of strength. You will know your walk-away number, recognize a clean offer when it arrives, and keep more attention on the outcome that matters: protecting as much of your hard-earned home equity as possible.
