Breaking your mortgage before renewal

Rates dropped, you're selling, or you need to borrow more. Breaking a closed mortgage mid-term is allowed, but it usually comes with a penalty that can run to thousands of dollars.

What the penalty is

On most closed mortgages the penalty is the higher of three months' interest or the interest rate differential (IRD). On variable-rate mortgages it's usually just three months' interest. The FCAC's example: $200,000 left at 6%, 36 months to go, and a comparison rate of 4%. Three months' interest is $3,000 and the IRD is $12,000, so the penalty is $12,000.

The IRD depends on the comparison rate your lender picks. Banks that use posted rates subtract the discount you got when you signed, and that can make the penalty much larger. Our prepayment penalty calculator shows both methods next to each other.

Options that can cost less

The five-year rule

Under section 10 of the federal Interest Act, once a mortgage has run more than five years, the borrower can repay it with at most three months' extra interest. This protects people with 7- and 10-year terms.

Before you decide

Ask your lender for the exact penalty in writing and how they calculated it. Federally regulated lenders that follow the mortgage prepayment code have to explain the method and the comparison rate. Then compare the penalty with the interest you'd save, using the renew vs switch calculator with the new rate.
