Mortgage renewal strategies that actually save money
Renewing your mortgage is the single easiest moment to save thousands of dollars — and it is also the moment most Canadians treat as an administrative formality. Recent surveys by CMHC and industry associations show that a large share of borrowers still simply sign the first offer their existing bank sends.
This guide walks through the specific tactics that make a difference: when to start, how to use a competing quote, when it makes sense to extend amortization, and how to structure prepayments so you close the term ahead.
Start 120 days out — always
Most Canadian lenders let you hold a rate for 90 to 120 days before your renewal date. That window is when you get quotes from a broker, another bank, or an online lender and use them as leverage with your current bank.
Once your maturity date passes and you have signed nothing, the bank often moves you to an automatic renewal at a rate well above what you could have negotiated.
Switch without re-qualifying
OSFI's 2024 update lets most uninsured borrowers switch lenders at renewal without re-passing the stress test, as long as the balance and amortization are not increasing. That was a real barrier before, because a household whose income had dropped could be trapped with its existing bank.
Insured borrowers already had this flexibility. Ask any quoting lender in writing whether the offer is a straight switch — that phrasing matters.
Reset amortization only if you need to
At renewal, you can usually reset your amortization up to the original schedule (25 or 30 years for a first-time or new-build insured mortgage). This lowers the payment but adds interest over time.
A better strategy for most households: keep the same amortization and use any monthly savings from a lower rate to make lump-sum prepayments within your allowed limits.
FAQ
- Can I break my mortgage before renewal to get a better rate?
- Yes, but you will pay a penalty. On a fixed mortgage the penalty is the greater of three months' interest or the interest rate differential (IRD), which can be very large mid-term.
- Does switching lenders cost anything?
- Straight switches are usually free — the new lender covers legal and appraisal costs to win your business. Always confirm in writing.
- Should I negotiate even if my bank's offer looks reasonable?
- Yes. The renewal offer is usually not the bank's best rate. A single competing quote from a broker often unlocks a discount of 0.15-0.40%.
- What if I fail the stress test at renewal?
- You can still renew with your current lender without re-qualifying. The stress test only bites if you switch lenders and are uninsured — and even that changed under OSFI's 2024 update.
