A mortgage renewal can arrive while a household is already managing childcare, property costs, other debt and savings goals. Waiting for a lender's renewal letter can leave little time to compare choices. The Financial Consumer Agency of Canada (FCAC) advises homeowners to start shopping around a few months before the term ends and notes that a renewal may happen automatically if the borrower does not act.
The useful first move: find the renewal date, gather the current loan details, and test the payment in your actual monthly budget before deciding whether to renew, negotiate or switch. Do not base the plan on a predicted Bank of Canada move or an online headline; use written offers and your contract.
Turn a possible payment change into a budget test
Suppose a fictional household currently pays $2,300 per month. A renewal offer lists a payment of $2,520. The difference is $220 a month, or $2,640 over 12 months ($220 × 12). This is arithmetic on the hypothetical payment figures, not an estimate of what any mortgage payment should be.
If the renewal is still a few months away, the household can test that $220 change by setting the amount aside each month while continuing its current payment. After three months, it would have $660 set aside ($220 × 3). That exercise does not prove the new payment will be affordable indefinitely, but it exposes whether the current budget can absorb the change without relying on credit or cutting an essential bill.
Run the test using the payment frequency and dates in the actual offer. Include property tax, utilities, insurance, maintenance, and any other amount that changes with the home; the mortgage payment alone is not the full housing budget.
Compare offers on more than the payment
A lower payment is not automatically a lower-cost choice. Check that each comparison uses the same outstanding balance and a comparable remaining amortization, then ask what changes in the term, rate type, prepayment privileges and total borrowing cost. If a new lender's offer has switching costs, include them.
For example, imagine two fictional written offers for the same balance and comparable amortization: Lender A quotes $2,520 a month; Lender B quotes $2,440 and charges $900 in one-time switching costs. The payment difference is $80 monthly. A simple payback calculation is $900 ÷ $80 = 11.25 months. Over 12 months the payment difference totals $960, leaving $60 after those stated costs ($960 − $900), before considering any other differences.
This small example is not enough to choose between offers. It assumes the payment estimates are comparable and counts only the stated switching cost. Ask both lenders for the complete figures and terms. FCAC lists potential costs such as discharge, registration, transfer or assignment fees and, where applicable, appraisal or administration fees. It also notes that mortgage insurance premiums may apply in some switching situations, such as when the loan amount increases or the amortization period is extended.
A short renewal checklist
- Put the term-end date on your calendar. Start reviewing options a few months beforehand rather than waiting for the renewal notice.
- Collect the same facts for each comparison. Record the current balance, payment amount and frequency, remaining amortization, renewal date, prepayment conditions and any secured line of credit or other linked borrowing.
- Ask your existing lender for the full renewal terms. Ask whether the renewal will be automatic, what the payment and term would be, and whether a different rate or term is available.
- Shop and negotiate. FCAC says borrowers can contact other lenders or mortgage brokers and negotiate with their current lender. Check the qualification requirements and all costs of a switch; a competing rate alone is not a complete comparison.
- Stress-test your household budget. Compare the written payment with current take-home cash, essential spending, debt minimums and savings. Keep a margin for costs that vary rather than assigning every dollar to the mortgage.
- Read the documents before accepting. Confirm payment dates, term, amortization, fees, insurance implications and any conditions that differ from the offer you compared.
When the plan needs another pass
If the payment test leaves little room for irregular expenses, revisit the entire housing budget and the cash buffer before committing. The Money Lab emergency-fund comparison helps test cash-reserve scenarios.

Do not treat the examples here as a current rate outlook. Lender offers, contract terms and a household's qualifying situation can change; use the exact documents for your mortgage and consult a qualified mortgage professional or legal/tax adviser for questions that depend on your circumstances.

Make the next step concrete
Write down the renewal date, ask for the complete renewal terms, and reserve time to compare at least one alternative. Then test the quoted payment against your household's budget. This is educational information, not personalized financial advice.
