The 5-Step Switch Process
- 1. Start 120 days before renewal. This gives you time to compare, lock a rate hold, and complete the switch paperwork without rushing.
- 2. Get your current lender’s renewal offer in writing. Use it as your baseline — you will beat it in almost every case.
- 3. Compare broker rates at mrates.ca. A broker accesses 30+ lenders including monolines that do not deal directly with consumers.
- 4. Confirm no stress test applies. Keep your loan amount and amortization unchanged to stay exempt.
- 5. Sign with the new lender before your current term ends. Your new lender pays off the old mortgage directly — no gap in coverage.

Frequently Asked Questions
Can I switch mortgage lenders at renewal without a stress test in Ontario?
Yes — since November 2024, Ontario homeowners with insured mortgages can switch lenders at renewal without passing the stress test, provided the loan amount and amortization stay the same as your current mortgage. This makes switching accessible to virtually any renewing homeowner in good standing with their current lender.
Is there a penalty to switch mortgage lenders at renewal?
No — switching at the natural end of your term (renewal) carries no prepayment penalty. Penalties only apply if you break your mortgage mid-term. This is different from refinancing mid-term, which may trigger an interest rate differential (IRD) penalty depending on your current lender’s terms.
How much can I save by switching mortgage lenders at renewal?
On a typical $600,000 mortgage, switching from a big bank posted rate (4.34%–4.54%) to a broker-accessed rate (3.94%) saves approximately $16,000–$21,000 over a 5-year term. The exact savings depend on your balance, term length, and the specific rate gap at the time you renew.
When should I start the process to switch lenders at renewal?
Start 120 days before your renewal date. Most lenders offer free rate holds for 90–120 days, which lets you lock in a competitive rate while completing the switch paperwork. Waiting until your renewal letter arrives leaves little time to compare and switch before your term ends.
