The renewal trap
Major Canadian lenders have spent decades studying borrower behaviour at renewal. The data is consistent: 60-70% of borrowers accept whatever rate is offered without negotiating or comparing.
Lenders price renewal offers accordingly. The renewal letter you receive 4-6 months before maturity is rarely the best rate the lender would actually approve — it's often 25-75 bps above their best advertised rate to new clients. Sometimes it's at the posted rate, with no discount applied at all.
On a $500,000 balance, that 50 bps gap is $2,500 per year, or $12,500+ over a 5-year term. Multiply by interest compounding and the actual lifetime cost is even higher.
The 90-day playbook
Day 90 — assess
- Pull your current mortgage balance and remaining amortization
- Note the offered renewal rate from your lender's letter
- Look up the current best rate in your category (5-year fixed vs variable) at major rate-comparison sites
- Calculate the spread: (offered rate − best market rate) × balance × 5 years
If the spread × balance × 5 years exceeds $5,000, you should definitely negotiate or shop. If it exceeds $15,000, you should almost certainly switch.
Day 80 — get competing quotes
- Talk to a mortgage broker (free for you — the lender pays them)
- Get 2-3 written quotes from competing lenders for the SAME product (5-year fixed if that's what you have, variable if that's what you want)
- Confirm the new lender's product terms: prepayment privileges, portability, fixed/variable conversion options
The competing quotes are your leverage. Without them, your lender has no reason to discount.
Day 70 — counter your existing lender
- Email or write to your existing lender's branch / specialist:
"My current renewal offer is [X.XX%]. I've received written quotes from competing lenders at [Y.YY%]. I would prefer to stay but need a rate that's competitive. Please advise the best rate you can offer."
- Most major banks have an "rate-match" or "retention" program that's invisible until you challenge the offered rate
- Discounts of 25-50 bps from the initial offer are common; sometimes 75 bps
Day 60 — compare net cost
- Compare the rate-matched same-lender offer vs the best switch offer
- Factor in switching costs: $1,500-$3,000 in legal + appraisal at the new lender (many lenders cover most or all of this in their offer)
- Same-lender renewals avoid switching costs but typically don't price as aggressively
Day 45 — make the decision
- Decide same-lender vs switch
- Give yourself 30+ days of buffer for paperwork — switching requires new applications, signatures, appraisal coordination
- Rushing renewals into the last 2-3 weeks before maturity often costs you negotiating leverage
Day 30 — execute
- Sign the same-lender rate hold OR submit the switch application to the new lender
- Confirm payment date and amount won't change unexpectedly
Same-lender vs switching — the stress test difference
Critical fact most borrowers don't know: same-lender renewals do NOT trigger a fresh stress test. The federal OSFI Guideline B-20 applies only to new mortgage originations. Renewing with your existing lender at your existing amortization is not a new origination.
Switching to a new lender IS a new origination. You'll be stress-tested at the higher of contract + 2% or 5.25%. If you can't pass that test today (because your income dropped, debts rose, or rates moved), you might be stuck with your existing lender even at a higher rate.
See stress test history for the full mechanics.
This dynamic is one of the most-discussed asks in Canadian mortgage policy: should renewal switching be exempt from re-stress? OSFI hasn't agreed yet.
What to negotiate beyond the rate
Rate isn't the only thing. Renewals are also a chance to restructure:
- Switch fixed to variable if you expect rates to drop in the next term
- Switch variable to fixed to lock in certainty
- Extend amortization to lower monthly payment (e.g., 22 years remaining → reset to 25 years)
- Increase prepayment privileges — some products offer 15% lump sum, others 20%, others 25%
- Add or remove a co-borrower
- Change payment frequency to accelerated bi-weekly (see biweekly vs monthly)
- Remove or restructure a HELOC that's bundled into your current setup
A renewal is a clean restart. Use it.
When to stay with your existing lender
Same-lender renewal often wins when:
- The rate-matched offer is within 15-25 bps of the best switch offer
- You don't qualify for a fresh stress test (income change, debt increase)
- Your current lender's product features (prepayment, portability, etc.) are better than the switch option
- You're nearing retirement and want simplicity
- The switch lender's transition costs eat the savings
When to switch
Switch when:
- The competing quote saves 50+ bps
- You qualify for a fresh stress test
- You want better product features the existing lender won't match
- Your existing lender's service / digital experience is poor
- You're combining the renewal with a larger refi or restructuring
Common renewal mistakes
- Waiting until 30 days out to start negotiating — too late, paperwork pressure forces you to accept
- Signing the first offer without comparing
- Assuming the rate is the lender's best — it almost never is
- Forgetting to ask about prepayment privilege changes
- Not factoring in stress test when considering a switch
- Switching for a tiny rate gain that doesn't cover legal costs
- Skipping the broker channel — it costs you nothing and gets you the market
What to do next
- Mark your renewal date in your calendar today
- Set a reminder for 4 months before maturity to start the playbook
- Use the refinance savings calculator to model the value of a 25-50 bps reduction
- Identify 1-2 mortgage brokers you'd want to talk to when the renewal window opens
- Don't accept the first renewal offer — even if it looks competitive
About one-third of borrowers do this work and capture the savings. The other two-thirds fund the discount.
