Switching Mortgage Lenders at Renewal in Canada: 2026 Straight-Switch Guide (No Stress Test)
Discover how Canadian homeowners can switch mortgage lenders at renewal in 2026 without re-qualifying under the Mortgage Qualifying Rate (MQR) stress test — under OSFI's (Office of the Superintendent of Financial Institutions) updated straight-switch exemption. This guide covers eligibility rules, key restrictions, and the critical distinction that this exemption applies only to federally regulated financial institutions (FRFIs) such as banks — not provincial credit unions.
