See the costs Ontario sellers commonly face at closing, from commission and legal fees to mortgage penalties and discharges, so proceeds are no surprise.

Key takeaways
  • Your net proceeds are the sale price minus several deductions, and the amounts depend on your listing agreement, your lawyer's quote and your mortgage.
  • A mortgage prepayment penalty is usually the higher of three months' interest and the interest rate differential, so it can be a large number.
  • Porting your mortgage, using prepayment privileges or waiting for the term to end can reduce or avoid a penalty in some cases.
  • Ask your lawyer early who will register the mortgage discharge, and get that in writing if the lender will do it.

The number on the offer is not the number that lands in your bank account. Between the sale price and your proceeds sit a handful of deductions, and some of them only become clear in the last week before closing.

This article walks through the costs sellers commonly meet in Ontario, which ones depend on your own contracts, and how to get real figures early. Exact amounts depend on your listing agreement, your mortgage and your agreement of purchase and sale, so treat this as a map and not a quote.

The main categories of seller costs

Most sellers should expect to look at the same short list of items. The amounts differ for every sale, so the useful question is where each figure comes from.

CostWhat it isWhere the amount comes from
Agent commissionPayment to the brokerage for selling the homeDepends on your situation, so it is worth confirming with a lawyer
Legal fees and disbursementsYour lawyer's work on the sale and out-of-pocket costsYour lawyer's quote or retainer
Mortgage payoutThe balance you owe the lender, plus interestAsk your lender for a figure for your expected closing date
Prepayment penalty or feeCharge for ending the mortgage earlyYour mortgage contract and lender's method
Discharge-related chargesCosts of removing the lender's charge from titleYour lender and your lawyer
AdjustmentsItems like property tax and utilities that may be sorted out between you and the buyerDepends on your agreement of purchase and sale, so your lawyer can confirm
Contract exit costsFees to end or transfer things like rented equipmentThe contracts themselves

Ask your lawyer for a draft statement of adjustments and an estimate of net proceeds before you commit to your next purchase, so you know what you will actually have to work with.

Your mortgage: payout and prepayment penalties

If you still have a mortgage, the payout is one of the main items to plan for. The balance is the easy part. The penalty for ending the contract early is the part that surprises people.

The Financial Consumer Agency of Canada says a prepayment penalty is usually the higher of three months' interest on the balance and the interest rate differential, often called the IRD. Lenders typically use the IRD when your rate is above the current market rate and you signed less than five years ago.

To show the scale, the FCAC gives an example of a $200,000 balance at 6% with 36 months left. The IRD was $12,000 against $3,000 in three months' interest, so the penalty was $12,000, and an administration fee may also apply. Your own figure depends on the amount prepaid, the months left, interest rates and your lender's method, and many banks publish penalty calculators.

There is also a federal rule for longer mortgages. On a mortgage not due for more than five years from its date, the borrower may pay it off after the five years by paying principal and interest plus three months' further interest in lieu of notice. It does not cover mortgages given by corporations or certain prescribed mortgages.

Ways to reduce or avoid a penalty

Do not assume that moving your mortgage to a different lender avoids the charge. Transferring to another lender before the term ends can trigger a prepayment penalty.

The discharge of your mortgage on closing

On closing, the lender's charge has to come off title. In electronic registration, the Law Society of Ontario advises lawyers to ask an institutional lender early whether the lender or the lawyer will prepare and register the discharge, and to get written confirmation if the lender will register it.

Your lawyer's closing duties include delivering the discharge funds to the lender in a timely manner and getting registration particulars to the buyer's lawyer. Where the lender registers its own discharge, the lawyer's undertaking may be limited to causing a discharge to be registered.

If you have a private mortgage, note that the Law Society's position is that, without an express term in the agreement of purchase and sale, lawyers should not give or accept personal undertakings to obtain and register discharges of private mortgages after closing. Raise this with your lawyer before you sign an offer.

Costs that catch sellers off guard

If you owned the home for less than 365 consecutive days, the gain is generally treated as business income and not a capital gain, subject to listed exceptions such as death, serious illness or an eligible relocation. An accountant can confirm how this applies to you.

What to do next

Penalties and contract terms vary, so it is worth having a lawyer review your numbers before you sign a purchase of your next home.

Frequently asked questions

Do I always pay a penalty to pay off my mortgage when I sell?

No. Prepayments within your lender's privileges generally carry no penalty, and an open mortgage allows prepayment without penalty. Porting the mortgage to a new home may avoid breaking the contract. Otherwise a penalty is usually the higher of three months' interest and the IRD.

How do I find out my exact penalty?

Ask your lender for a written figure for your expected closing date. The cost depends on the amount prepaid, the months left, rates and the lender's own method, and banks often publish calculators. An administration fee may also apply.

Do I have to report the sale of my home if it is tax-free?

Yes. The sale of a principal residence must be reported on your T1 return for the year of sale on Schedule 3, even if the entire gain is exempt. For dispositions in 2017 and later, Form T2091(IND) must also be completed.

What if I forget to designate my home as my principal residence?

You should ask the CRA to amend that year's return. The CRA may accept a late designation, but the penalty is the lesser of $8,000 or $100 for each complete month from the original due date to the date of your request. An accountant can help with the request.
