Key takeaways
  • A closed-mortgage penalty is usually the higher of three months' interest or the interest rate differential.
  • After five years on a mortgage not due until later, you can pay it off by paying what is owing plus three months' interest in lieu of notice.
  • Other claims on title, such as property tax liens, can also affect your sale.

If you still owe money on your home, selling can mean ending your mortgage early, and the cost depends on your contract. How the payout fits into your closing depends on your lender and your sale agreement, so it is worth confirming with a lawyer.

This article explains the general rules on penalties, the statutory right to pay off after five years, and other things that can be registered against your home. Your own mortgage terms and your lender's payout statement govern the exact numbers.

The basic idea: the lender is paid on closing

If you still owe money on your mortgage when you sell, the payout is something to sort out with your lender well before closing. Exactly how and when that happens depends on your mortgage terms, your lender and your agreement of purchase and sale. A payout statement from your lender shows what is owing, and your lawyer can explain how it fits into your closing.

If a mortgagee cannot be found, or a discharge cannot otherwise be obtained, the court may allow the amount owing to be paid into court and order the mortgage discharged. A registered court discharge order has the same effect as a discharge signed by the mortgagee. This is an unusual route, so get advice if you face it.

Prepayment penalties

Ending a closed mortgage early often brings a penalty. It is usually the higher of three months' interest or the interest rate differential (IRD). Lenders generally use the IRD when the mortgage rate is above the current rate and the contract was signed less than 5 years ago. IRD comparisons are typically based on the lender's posted rates.

Formulas differ by lender and contract, so read your mortgage terms. Federally regulated lenders must explain how they calculate the charge and choose the IRD comparison rate. When you confirm a prepayment, the lender must give a written statement of the calculation, including the comparison rate and remaining term used. On request, they must give a written statement of the current charge through a toll-free line.

Mortgage typeWhat to expect
ClosedPenalty usually the higher of three months' interest or the IRD.
OpenCan be broken without a prepayment penalty, though other fees may apply.

Ways to lower the cost

Even with an open mortgage, sellers breaking a mortgage may face administration, appraisal, reinvestment and discharge fees, and may have to repay any cash back received. Ask your lender for a full list of charges before you set a closing date.

The five-year rule

There is also a statutory right to pay off a long mortgage. Under the federal Interest Act, if a mortgage is not due until more than five years after it was made, the borrower may pay it off at any time after five years by paying the principal and interest owing plus three months' further interest in lieu of notice.

Ontario's Mortgages Act gives the same right. Once more than five years have passed on a mortgage not due until after five years, the borrower may redeem by paying the amount due plus three months' interest in lieu of notice. Whether this applies to your mortgage depends on its terms and dates, so confirm with a lawyer.

Other claims on title and what to do next

The mortgage may not be the only thing registered on your property. Each of these can affect your closing:

Frequently asked questions

How much will it cost to pay off my mortgage early?

For a closed mortgage the penalty is usually the higher of three months' interest or the IRD. Your contract and your lender's payout statement give the exact figure.

Can I avoid a penalty by porting my mortgage?

Porting, meaning keeping the rate and terms for a new home, is one way to lower a penalty. Whether it is available depends on your lender and contract.

Is there a different rule after five years?

Yes. If the mortgage is not due until more than five years after it was made, you may pay it off after five years by paying what is owing plus three months' interest in lieu of notice.

What if my lender cannot be found to sign a discharge?

A court may allow the amount owing to be paid into court and order the mortgage discharged. A registered court order has the same effect as a discharge signed by the mortgagee.
