The Bank of Canada raised its policy interest rate to 2.5 per cent in October 2026, marking the first increase in three years. If you have a variable-rate mortgage, your payment or amortization period will rise within days. Fixed-rate mortgage holders are not immediately affected, but anyone renewing or buying soon will face higher qualifying rates and potentially higher mortgage rates. The hike also tightens the mortgage stress test, making it harder to qualify for the amount you could borrow a month ago.

What This Means for Variable-Rate Mortgages

Variable-rate mortgages move in step with lender prime rates, which track the Bank of Canada’s policy rate. According to the Bank of Canada, when the policy rate increases, most lenders raise their prime rate by the same amount, typically within one to three business days. If your mortgage has an adjustable payment structure, your monthly payment increases immediately. If you have a fixed payment with a variable rate, more of your payment goes to interest and less to principal, extending your amortization period and potentially triggering a payment adjustment at renewal if the balance has not decreased as expected.

The jump to 2.5 per cent from the previous rate means the typical lender prime rate moves from around 3.95 per cent to 4.20 per cent (prime rates are generally set 2.2 percentage points above the policy rate, though the exact spread varies by lender). On a CAD 400,000 mortgage, that 0.25 percentage point increase adds roughly CAD 60 per month to your payment, or CAD 720 annually. Homeowners with variable-rate mortgages should review their amortization schedule and confirm whether their current payment covers enough principal to stay on track, as covered in foundational texts such as Principles of Macroeconomics 3e.

Impact on Fixed-Rate Mortgages and Renewals

Existing fixed-rate mortgages are locked in for the term, so this hike does not change your current payment. However, the rate environment you renew into has shifted. Lenders price fixed-rate mortgages based on bond yields and their cost of funds, not the policy rate directly, but rising policy rates generally push fixed mortgage rates higher over time as the yield curve adjusts.

If your mortgage term ends in the next 6 to 12 months, the rates available at renewal will likely be higher than when you last locked in. According to the Financial Consumer Agency of Canada, most Canadian mortgages renew every one to five years, and renewal is the moment you renegotiate your rate and term. Lenders are not required to offer you their best rate at renewal, so it is essential to shop around with multiple lenders and mortgage brokers at least 120 days before your term expires to secure the most competitive rate for your situation.

Higher Qualifying Rate Under the Stress Test

The OSFI mortgage stress test requires you to qualify at the greater of your contract rate plus 2 percentage points or the published qualifying rate (currently 5.25 per cent as of mid-2026, subject to regular adjustment). As policy rates and market rates rise, the stress test effectively becomes more restrictive because your contract rate increases, pushing your qualifying rate higher.

For first-time buyers and those refinancing or switching lenders (which triggers a full re-qualification), this means you may qualify for a smaller mortgage amount than you would have a few months ago. On a household income of CAD 100,000, a 0.25 percentage point increase in the qualifying rate can reduce borrowing capacity by roughly CAD 10,000 to CAD 15,000, depending on your debt load and down payment. Anyone planning to purchase or refinance in the coming months should get a pre-approval quickly to lock in current qualification thresholds, though the rate itself remains subject to change until closing.

What to Do Next

If you have a variable-rate mortgage, contact your lender to confirm your new payment amount or amortization impact and consider locking into a fixed rate if you expect further hikes or want payment certainty. If you are renewing within the next year, start shopping for rates now rather than waiting for your lender’s renewal offer. If you are buying or refinancing, get pre-approved as soon as possible to understand what you can still afford under the new qualifying rate, and confirm all figures with a licensed mortgage broker or your financial institution for your personal situation.

Policy rates and mortgage qualification rules change frequently. This information is current as of October 2026. Always verify rates, stress test requirements, and eligibility with a licensed mortgage professional before making decisions.
