Closed Mortgage

Definition

A closed mortgage restricts how much of the balance can be prepaid before the term ends — beyond the lender’s prepayment privileges, paying it off early typically triggers a prepayment penalty — in exchange for a lower rate than an open mortgage.

What happens if a closed mortgage is paid off early?

Most mortgages in Canada are closed. Lenders allow a set amount of extra prepayment each year through prepayment privileges, but paying beyond that — or discharging the mortgage entirely before the term matures — usually means paying a prepayment penalty, calculated as either three months’ interest or the interest rate differential, whichever the lender’s formula produces for a fixed-rate mortgage.

The right to prepay isn’t unlimited even with a penalty, either: section 10 of the Interest Act caps the maximum penalty at three months’ interest for an individual borrower once five years of a longer term have elapsed, regardless of the rate originally locked in.

How it’s used in Canada

The default structure: closed terms are the norm in the Canadian market, offered across every term length from one to ten years.

Interest Act protection after five years: under section 10 of the Interest Act, an individual borrower can prepay a closed mortgage after five years have passed with a penalty capped at three months’ interest, even on a longer original term.

Variable vs. fixed penalties differ: closed variable-rate mortgages are typically charged three months’ interest to break early, while closed fixed-rate mortgages use whichever is greater of three months’ interest or the interest rate differential.

Prepayment privileges soften the restriction: most closed mortgages still allow annual lump-sum and payment-increase privileges set by the lender, on top of regular scheduled payments.
