Key takeaways
  • Ontario sellers do not pay land transfer tax; that is a buyer cost.
  • The usual seller charges are commission, HST on commission, legal fees and disbursements, mortgage payout or penalty, and adjustments.
  • Paying off a mortgage early because you sell can trigger a prepayment penalty, and porting may be an option if you are buying another home.
  • Some costs only apply in certain sales, such as condominiums, tenanted homes and estates.

Seller closing costs are the charges that come off your sale proceeds on or before closing. Some are certain, some depend on your mortgage or your type of property, and a few are optional. Knowing which is which helps you price your home and plan your next move.

This list goes through each item in plain language. Amounts that depend on negotiation, such as commission and legal fees, are not set by law in the material reviewed here, so get written figures before you list.

The core costs almost every seller sees

Ontario describes seller costs as commission, HST on commission, legal fees and disbursements, mortgage payout or penalty, and adjustments. Land transfer tax is not on that list because only the buyer, who tenders the conveyance for registration, pays it.

Costs that depend on your situation

Remember that the estate pays this tax, not the personal representative.

The mortgage line deserves a closer look

If you sell before your mortgage term ends, paying off the whole mortgage can trigger a prepayment penalty. The penalty is usually the higher of three months' interest on what you still owe or the interest rate differential. In the Financial Consumer Agency of Canada example, a penalty of $12,000 applied where three months' interest would have been $3,000, and an administration fee may be added.

Two ways this cost can shrink are worth asking about. First, if you are buying another home, ask whether your lender allows you to port the mortgage. Second, if your mortgage runs longer than five years, the Mortgages Act and the Interest Act contain a five-year rule that lets the borrower pay what is owed plus three months' interest. That rule excludes mortgages given by corporations and certain other borrowers.

If a lender cannot be found or a proper discharge cannot be obtained without undue delay, the court may allow payment into court and order the mortgage discharged. This is uncommon, and your lawyer would guide you.

Frequently asked questions

Is there a fixed percentage for seller closing costs in Ontario?

Not in the rules covered here. Commission and legal fees are negotiated, and the mortgage penalty depends on your contract, so the total varies from sale to sale.

Do I pay HST when I sell my house?

Not on the price of a typical used home sold by an individual. You do pay 13% HST on taxable services such as the commission and legal fees.

Who pays for the condominium status certificate?

The fee is capped at $100 including taxes, but who bears it in a given sale depends on your agreement and your lawyer's advice.

Do I need to report the sale on my tax return?

Yes. Principal residence sales must be reported by designating the home on Schedule 3 of your T1 return and, for sales from 2017, completing Form T2091.
