Related Questions

How does the stress test affect my 2026 renewal options?

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%.

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.

The November 21, 2024, OSFI B-20 update removed the stress test for uninsured renewals. This 'straight switch' mentality has migrated to internal blend-and-extends, where lenders use existing borrower history to bypass the 2% MQR buffer.
