Your mortgage payment can increase at renewal when the rate on your new term is higher than the rate on your existing mortgage.
The comparison that matters is not between today’s rate and the market peak. It is between today’s available rate and the rate written into your current mortgage contract. For Ontario homeowners who secured unusually low rates in 2021 or early 2022, that difference can be substantial.
Why are mortgage renewal payments increasing?
Many mortgages renewing now were arranged when rates were near historic lows.
The Bank of Canada estimated that approximately 60% of mortgage holders renewing during 2025 and 2026 would experience a payment increase. Most of those borrowers held five-year fixed mortgages originating during the low-rate period. See the Bank of Canada analysis.
CMHC’s 2026 Mortgage Consumer Survey found that 35% of recent renewers reported higher payments. The average reported increase was approximately $375 per month. See the CMHC survey results.
That is an average, not a prediction for your mortgage. Your actual change depends on your balance, rate, amortization and mortgage structure.
Don’t confuse the Bank of Canada rate with fixed mortgage rates
The Bank of Canada’s policy rate has a strong influence on variable-rate mortgages and lender prime rates.
Fixed mortgage rates work differently. They are influenced more directly by bond-market pricing, lender funding costs, competition and the risk attached to the mortgage.
Government bond yields can remain elevated or move higher even when the Bank of Canada holds or lowers its policy rate. That is why waiting for the next Bank of Canada announcement does not guarantee that a fixed mortgage offer will improve.
What could the payment change look like?
Consider a simplified example:
- Mortgage balance: $450,000
- Current rate: 1.99%
- New rate: 4.50%
- Remaining amortization: 20 years
- Payment frequency: Monthly
The approximate payment would increase from $2,273 to $2,837 per month. That is an increase of roughly $564 per month.
This is an illustration using Canadian semi-annual mortgage compounding. It does not include fees, insurance, changes to payment frequency or other adjustments. Available rates and payments depend on the borrower, property, mortgage type and lender.
The point is not to predict your payment. It is to show why a seemingly small rate difference can have a meaningful effect when applied to a large mortgage balance.
To try your own numbers, use the Ontario Mortgage Renewal Decision Kit. It includes a payment comparison, an offer worksheet and questions to bring to your review.
Compare these five numbers before renewing
Your lender’s renewal offer may be convenient, but convenience does not confirm that the mortgage still fits your plans.
- Your current payment. Start with what leaves your account today.
- Your proposed new payment. Calculate the dollar increase, not only the difference between the two interest rates.
- Your remaining amortization. Confirm whether the offer keeps your existing mortgage-free date or extends it.
- Your total interest cost. A lower payment can still cost more if it stretches the debt over a longer period.
- What remains in your monthly budget. The payment has to work alongside property taxes, utilities, insurance, other debts, savings and normal living expenses.
The Financial Consumer Agency of Canada warns homeowners to think carefully before extending their amortization simply to reduce the payment. A longer repayment period can add thousands or tens of thousands of dollars in interest. Read FCAC’s mortgage renewal guidance.
Should you accept your lender’s renewal offer?
Not automatically.
Your current lender’s offer is one option. It may ultimately be the right option, but it should still be compared with alternatives.
Look beyond the advertised rate. Review the term, fixed versus variable pricing, prepayment privileges, penalty calculations, portability, restrictions, renewal flexibility and total borrowing cost.
Switching lenders may require a new application and qualification. It can also involve legal, appraisal or discharge costs depending on the mortgage. Those costs should be included in the comparison rather than ignored.
Renewal is a decision, not paperwork
The most useful renewal question is not simply, “What rate can I get?”
It is, “What will this renewal do to the rest of my finances?”
A proper renewal review should consider your payment, total interest, mortgage-free date, monthly cash flow, other debts and plans for the property.

Frequently asked questions about mortgage renewal payments
Why can my mortgage payment increase at renewal?
Your payment can increase when the rate on your new mortgage term is higher than your existing contractual rate. Your remaining balance, amortization, payment frequency and any changes made at renewal can also affect the payment.
Can my fixed mortgage rate rise when the Bank of Canada rate stays the same?
Yes. Fixed mortgage rates are influenced by bond yields, lender funding costs, competition and the mortgage’s risk profile. They do not move directly with every Bank of Canada policy-rate decision.
How much are mortgage payments increasing at renewal?
There is no universal increase. CMHC’s 2026 Mortgage Consumer Survey found that 35% of recent renewers reported a higher payment, with an average increase of approximately $375 per month. Your result depends on your mortgage balance, old rate, new rate and remaining amortization.
Should I accept my bank’s mortgage renewal offer?
Not before comparing it with other available options. Review the rate, payment, term, amortization, restrictions, prepayment privileges, penalties and total borrowing cost. Your existing lender may still be the right choice, but the offer should be tested first.
Can extending my amortization lower my renewal payment?
Yes. Extending the amortization can reduce the required payment, but it usually delays your mortgage-free date and increases the total interest paid. Compare the immediate cash-flow relief with the long-term cost.
When should I start reviewing my mortgage renewal?
Start before the renewal offer becomes urgent. Beginning several months ahead gives you time to review your finances, compare lenders, gather documents and decide whether changes to the mortgage are appropriate.
