Breaking a mortgage before the end of its term is sometimes the right move, and sometimes an expensive one. The difference usually comes down to how your lender calculates the penalty, what type of mortgage you have, and what you are trying to achieve. This guide walks through how penalties work in Ontario and the options worth comparing before you sign anything.
What "breaking your mortgage" means
Your mortgage has two timelines: the amortization (the total time to pay off the loan, often 25 or 30 years) and the term (the length of your current contract, often 1 to 5 years). Breaking your mortgage means ending the term early. People do this to sell a home without porting, to refinance and access equity, to consolidate debt, or to move to a different lender before renewal. In most cases the lender charges a prepayment penalty for ending the contract early.
Three months' interest vs the interest rate differential (IRD)
Most lenders in Canada use one of two penalty formulas, and many charge whichever is greater.
Three months' interest. This is roughly your outstanding balance multiplied by your interest rate, divided by four. It is the simpler and usually the smaller of the two calculations.
Interest rate differential (IRD). The IRD tries to compensate the lender for the interest it loses if it has to re-lend your money at a lower rate for the rest of your term. It compares your contract rate with a comparison rate for a term close to the time you have left, then applies the difference to your balance for the remaining months. How each lender picks that comparison rate varies, and some lenders factor in discounts you received when you signed. That is why two borrowers with similar balances can face very different IRD penalties.
The only reliable number is the one your lender provides. Calculators are useful for a rough idea, but they cannot reproduce every lender's method.
Fixed vs variable: why it matters
With a variable-rate mortgage, the penalty is typically three months' interest. That makes variable mortgages more predictable to break.
With a fixed-rate mortgage, the penalty is often the greater of three months' interest or the IRD. Depending on your lender's formula and how much time is left on the term, the IRD can be several times larger than three months' interest. Reading your mortgage commitment and the lender's prepayment terms is an important first step.
When breaking can make sense
Breaking early can be reasonable when the benefit clearly outweighs the total cost. Examples include:
- Consolidating high-interest debt where the savings over time exceed the penalty and fees
- Accessing equity for a renovation, investment or family need that can't wait
- Selling a home when porting the mortgage isn't possible or practical
- Changing life circumstances, such as separation, where the mortgage has to be restructured
The math should include the penalty, legal fees, any appraisal or discharge fees, and the full cost of the new mortgage over its term, not just the payment.
Blend-and-extend
Some lenders offer a blend-and-extend: you stay with the same lender, and your existing rate is blended with a current rate while the term is extended. This can avoid a penalty, or reduce it, but the blended rate and the terms are set by your lender. It is worth comparing the blended offer against the cost of breaking and moving.
Porting your mortgage
If you are selling and buying, many mortgages can be ported, meaning your existing rate, balance and term move to the new property. Porting rules differ by lender, including how long you have between closing the sale and the purchase, and how any extra borrowing is priced. You will usually need to qualify again for the new property.
Waiting for renewal
If your term ends within a few months, waiting may be the simplest option. At renewal you can move to another lender without a prepayment penalty. Lenders commonly allow a rate hold of up to about 120 days for a switch, so starting the conversation four months before maturity gives you time to compare offers.
Switching lenders at renewal
Your current lender's renewal letter is a starting point, not the only option. At renewal you can switch to another lender, subject to qualifying. A Mortgage Broker can compare offers from many lenders, review prepayment privileges and penalty terms, and help you choose a mortgage that fits your plans for the next term, including how easy it will be to break if your plans change.
Ask for a payout statement
Before deciding, ask your lender for a payout statement or a written penalty quote with a specific date. It should show your balance, the penalty, and any discharge or administration fees. Penalty quotes change as your balance and the remaining term change, so check the date and request an update if your timing moves.
Next steps
Collect your mortgage statement, your commitment or renewal letter, and a current penalty quote. With those in hand, you can compare breaking now, blend-and-extend, porting, or waiting for renewal side by side.
