Cost of Selling a House in Ontario: 2026 Seller's Guide

Every seller asks the same first question: "What will I actually walk away with?" Between commission, HST, legal fees, mortgage penalties and prep costs, the gap between your sale price and your net proceeds is bigger than most people expect — for a typical Ontario seller, all-in costs usually land somewhere between roughly 4% and 7% of the sale price. Here is every cost line, what it typically runs in the GTA in 2026, and a full worked example so you can estimate your own net before you list.

The seller's cost list at a glance

• Real estate commission + HST — the largest cost by far
• Legal fees and disbursements — typically $1,000–$2,500 for a sale
• Mortgage discharge fee — usually a few hundred dollars
• Mortgage prepayment penalty — $0 if your term is up; potentially thousands if you break a fixed term early
• Pre-listing prep — staging, repairs, cleaning, junk removal
• Status certificate — condo sellers only, capped at $100 in Ontario
• Closing adjustments — property tax and utility true-ups (can go either way)
• Moving costs

Real estate commission: the big one

Commission in Ontario is always negotiable — there is no set or standard rate, and no rule that requires you to pay any particular percentage. That said, commonly quoted total commissions in the GTA range from about 3.5% to 5% of the sale price, typically split between the listing brokerage and the buyer's brokerage (the buyer's-side portion is what motivates thousands of agents to show your home).

Two things sellers often miss:

• HST applies to commission. Ontario's 13% HST is charged on the commission itself. On a $50,000 commission, that is another $6,500.
• What's included varies a lot. Some listing packages include professional photography, floor plans, video, staging consultation and paid advertising; others don't. When you compare rates, compare the full marketing plan — not just the percentage. Our selling page breaks down what a full launch should include.

Legal fees and disbursements

You need a real estate lawyer to close a sale in Ontario. Sales are simpler than purchases (no title registration, no land transfer tax filings), so fees are lower: most GTA sellers pay roughly $1,000–$2,500 including disbursements. Your lawyer discharges the mortgage, prepares the statement of adjustments, answers requisitions from the buyer's lawyer, and wires you the net proceeds.

Mortgage discharge — and the penalty trap

If you still have a mortgage, two separate costs apply:

• Discharge/administration fee: most lenders charge a few hundred dollars to prepare the discharge.
• Prepayment penalty: this is the one that surprises people. If you break a fixed-rate mortgage mid-term, the penalty is typically the greater of three months' interest or the interest rate differential (IRD) — and IRD can run to thousands or tens of thousands of dollars depending on your rate, balance and time remaining. Variable-rate mortgages usually charge three months' interest. If you're buying your next home, ask your lender about porting the mortgage instead of breaking it.

Get your exact payout statement from your lender before you list — it changes the net-proceeds math more than any other single line.

Pre-listing prep: staging, repairs, cleaning

Homes that show well sell faster and invite stronger offers, especially in a market where buyers have choices. Typical prep spending in the GTA:

• Staging: anywhere from a few hundred dollars for a consultation to several thousand for full furniture staging of a vacant detached home. Many listing agents include a consultation or partial staging in their package — ask.
• Repairs and paint: minor fixes, touch-up paint and lighting updates usually return more than they cost.
• Cleaning and junk removal: a deep clean and decluttering are the cheapest high-impact money you'll spend.

Selling a condo? Budget for the status certificate

Buyers will almost always make their offer conditional on reviewing the status certificate — the package that shows the condo corporation's finances, reserve fund and any special assessments. In Ontario the fee is capped at $100 (including tax) under the Condominium Act, though rush ordering through third-party portals can cost more. Order it early so a conditional offer isn't stuck waiting.

Closing adjustments: the true-up on closing day

The statement of adjustments settles who owes what for the year: if you prepaid your property taxes past the closing date, the buyer credits you back; if taxes are owing, you credit the buyer. The same logic applies to utilities on flat-rate billing, rental equipment contracts (hot water tank, furnace, water softener — these are either paid out, assumed by the buyer, or credited), and prepaid condo fees. Adjustments can move money in either direction — your lawyer calculates the exact figure.

What Ontario sellers do NOT pay

Good news: land transfer tax is a buyer cost in Ontario, not a seller cost. You paid it when you bought; you don't pay it again when you sell. (Buyers in Toronto pay it twice — provincial plus municipal — which is one reason closing costs differ so much across the GTA. Our buyer closing-costs guide covers that side of the table.)

Taxes: principal residence, capital gains, and the flipping rule

• Principal residence: if the home was your principal residence for every year you owned it, the gain is generally tax-free under the principal residence exemption — but you must still report the sale on your tax return.
• Investment or secondary property: a portion of your gain is taxable as a capital gain. Track your adjusted cost base (renovations count) and talk to an accountant before you sell.
• The anti-flipping rule: since January 1, 2023, profit on a residential property sold within 365 days of purchase is generally taxed as fully taxable business income — no principal residence exemption — unless a listed life event applies (death, separation, disability, job relocation, insolvency and similar).
• Non-resident sellers face withholding and clearance-certificate requirements — specialist advice is essential.

This is general information, not tax or legal advice — confirm your situation with an accountant and your lawyer.

Worked example: selling a $1,000,000 Brampton detached

Illustrative numbers only — your commission, legal fees and prep costs will vary:

• Commission at 5% total: $50,000
• HST on commission (13%): $6,500
• Legal fees and disbursements: $1,500
• Mortgage discharge fee: $300
• Staging and prep: $2,500
• Moving: $1,500
• Total: about $62,300 — roughly 6.2% of the sale price

On the same sale with a negotiated 4% total commission, the total drops to about $51,000. That one conversation is worth more than every other cost-saving tactic combined — but weigh it against the marketing plan and buyer-side incentive you're getting in return.

How to keep more of your sale price

• Time your mortgage. Selling near your renewal date — or porting — can eliminate the penalty entirely.
• Price it right the first time. Overpricing then chasing the market down usually nets less than pricing on the comparables from day one. A proper comparative market analysis against actual sold prices — not asking prices — is the foundation; that's exactly what we build from live TRREB data on our seller side.
• Spend prep money where buyers see it: paint, lighting, curb appeal, deep clean. Skip the major renovation — you rarely recover it at sale.
• Compare full listing packages, not just commission percentages.

Where you sell changes what comes next

Most GTA sellers are also buyers — and your selling costs are only half the move. If you're selling in Brampton or Mississauga and buying your next home in the GTA, the buy-side closing costs (land transfer tax above all, doubled inside Toronto) belong in the same spreadsheet. Browse current listings on our buy page, or read our Brampton vs Mississauga comparison if you're weighing where to land next.
