Canada's 2026 Mortgage Stress Test Explained: Switches, MQR Rates & Qualification Rules
The Minimum Qualifying Rate (MQR) for uninsured mortgages is the greater of 5.25% or the contract rate plus 2% — borrowers must demonstrate they can afford payments at this higher rate.
Portfolio Loan-to-Income (LTI) limits now apply to federally regulated lenders, capping the share of high-LTI mortgages in their books to manage systemic risk.
The Minimum Qualifying Rate (MQR) is currently the greater of 5.25% or your contract rate plus 2% — knowing this number helps you understand exactly what income and debt levels you need to qualify.
Straight switches (same mortgage amount, same amortization, new lender) are now simpler under 2026 OSFI rules, potentially saving you legal fees and reducing paperwork at renewal.
With a lower rate secured through a straight switch, you may reduce your monthly mortgage payments — freeing up hundreds of dollars each month for savings, investments, or everyday expenses.
