Should You Switch Lenders or Stay at Renewal?

Related Questions

What's the difference between insured and uninsured mortgage renewals?

Insured mortgages face stricter CMHC/Sagen constraints while uninsured mortgages enjoy flexible OSFI-only guidelines.

Should I consider switching lenders or negotiate with my current lender?

Your switching decision hinges on rate differential versus requalification risk, with break-even analysis determining optimal strategy.

When should I start my mortgage renewal process?

Start your renewal process 120-180 days before your current term expires to maximize your strategic options.

How do CMHC insurance rules affect my 2026 renewal?

If your mortgage is CMHC-insured (less than 20% down payment originally), you're limited to 25-year maximum amortization at renewal.

Same-lender renewals and uninsured straight switches (OSFI, November 21, 2024) are exempt from the prescribed MQR. A refinance, an insured switch, or any increase in loan amount still requires the stress test — greater of 5.25% or contract + 2%.

  • Qualifying rate formula: higher of contract rate + 2.0% OR 5.25% minimum floor
  • Example impact: 4.79% offered rate requires 6.79% qualification (reduces borrowing power ~20%)
  • Applies to new mortgages, refinances, and insured switches at federally regulated lenders. Uninsured straight switches (same amount, same remaining amortization) have been exempt from the prescribed MQR since November 21, 2024.
  • Current lender leverage: they know you can renew without requalifying
