Fixed vs. variable mortgages in Canada

The better structure depends on the payment risk you can absorb, how long you expect to keep the mortgage, and the actual contract—not on a prediction of rates alone.

What to do first

  1. Confirm whether the variable option has a fixed payment or a payment that changes with the interest rate.

  2. Compare payments and interest at the offered rates, then test the variable option at higher rates.

  3. Review prepayment penalties, conversion rights, portability, and whether the mortgage is open or closed.

  4. Choose the option whose payment and renewal risk fit the household budget even if the rate moves against you.

Important considerations

Variable payment structures differWith an adjustable payment, the payment changes as rates change. With a fixed-payment variable mortgage, more of the payment may go to interest as rates rise, potentially reaching a trigger rate.

Fixed does not mean flexibleThe rate and scheduled payment are predictable during the term, but breaking a closed fixed mortgage may produce a material interest-rate-differential penalty.

Compare the complete contractRate is only one term. Payment privileges, portability, conversion rights, collateral registration, fees, and penalty treatment affect the outcome.
