Renewal tips

Don't just sign what your lender sends.

Your lender's renewal offer is almost never their best rate. They're counting on the fact that most borrowers will simply sign and renew without shopping around.

  • Start shopping 120 days before your renewal date — most lenders will honour a rate hold that long
  • Use a mortgage broker to access rates from multiple lenders at once — they do the shopping for you
  • Switching lenders at renewal typically involves no penalty and minimal paperwork
  • Consider whether fixed or variable makes more sense given current rate direction — the Bank of Canada cut to 2.25% as of 2025
  • A shorter term (1–3 years) may make sense if you believe rates will continue to fall
