Key Takeaway

The Bank of Canada’s October 2026 policy rate decision affects variable-rate mortgage holders immediately through changes to the prime rate. When the Bank cuts its policy rate, your lender’s prime rate typically drops by the same amount within days, lowering your monthly payment if you have a variable-rate mortgage. Conversely, a rate hold or hike means your payment stays the same or rises. The decision does not affect fixed-rate mortgages already locked in for their term.

How the Policy Rate Moves Your Variable Mortgage Rate

The Bank of Canada sets the policy interest rate (also called the overnight rate or target rate), which influences the prime rate that Canadian lenders charge. According to the Bank of Canada, the policy rate is the foundation for short-term borrowing costs across the economy.

Variable-rate mortgages are priced as prime plus or minus a spread (for example, prime minus 0.50 per cent). When the Bank of Canada cuts the policy rate by 25 basis points (0.25 percentage points), the major lenders typically lower their prime rate by the same amount within one or two business days. Your variable mortgage rate adjusts automatically, and your next monthly payment reflects the change.

If the Bank holds the rate steady, your variable rate and payment stay the same. If the Bank raises the rate, your payment increases.

What October’s Decision Means for Your Payment

For a C$400,000 variable-rate mortgage at prime minus 0.50 per cent with a 25-year amortization, a 25-basis-point cut in the policy rate (and prime) reduces the monthly payment by approximately C$55 to C$65, depending on the remaining balance and term. Over a full year, that cut saves roughly C$700 in interest.

A rate hold means no immediate change to your payment. A 25-basis-point hike adds about the same amount to your monthly cost.

The actual impact depends on your remaining principal, your lender’s spread, and whether you are in a variable-rate mortgage with adjustable payments (where the payment changes each time the rate moves) or a fixed-payment variable mortgage (where the payment stays the same but the principal-versus-interest split changes, affecting your amortization).

Term Versus Amortization: The Canadian Mortgage Structure

Canadian mortgages separate the term (the period for which your rate and contract are locked, typically one to five years) from the amortization (the total payoff period, commonly 25 or 30 years). As explained in general mortgage finance principles covered in foundational texts such as Principles of Finance, interest rate movements directly affect the cost of borrowing and the allocation of payments between principal and interest.

A variable-rate mortgage carries a rate that can change during the term. At the end of the term, you renew, refinance, or pay off the mortgage. The October rate decision affects only the rate during your current term, but the cumulative savings or costs from rate changes influence your balance at renewal and your options when the term ends.

What to Consider Now

If you hold a variable-rate mortgage, review your monthly statement to confirm the new rate (if the Bank cut) and the updated payment. Check whether your mortgage is adjustable-payment or fixed-payment variable, since the mechanics differ.

If you are approaching renewal or considering switching from variable to fixed (or vice versa), compare the current variable rate (prime plus or minus your spread) against the fixed rates your lender offers. The Financial Consumer Agency of Canada provides educational resources on understanding rate options and prepayment privileges.

The decision to lock in a fixed rate or stay variable depends on your risk tolerance, your financial cushion to absorb future rate increases, and the interest rate outlook. Mortgage products and eligibility vary by lender and province, so confirm current terms with a licensed mortgage broker or your financial institution for your personal situation.

Next Step

Contact your lender or mortgage broker to confirm your updated rate and payment following the October decision. If you are within six months of renewal, request rate-hold quotes for both fixed and variable options to compare your choices before your term ends.
