How to Pass Canada's Mortgage Stress Test in 2026

What is the Mortgage Stress Test?

Canada's mortgage stress test requires all borrowers at federally regulated lenders to qualify at the higher of their contracted rate + 2%, or 5.25%. This reduces your maximum purchase price by approximately 15–20%.

How It's Calculated

If your lender offers you 4.89%, you must prove you could afford payments at 6.89% (4.89% + 2%). Your monthly payment at 6.89% must still fit within the GDS and TDS ratio limits.

• GDS (Gross Debt Service) — max 39%: Housing costs ÷ gross monthly income
• TDS (Total Debt Service) — max 44%: All debts ÷ gross monthly income
• Heat: Lenders add $150/month regardless of your actual bill

5 Ways to Qualify for More

1. Add a co-borrower — Including a spouse or parent increases total income significantly
2. Pay down debts — Every $200/mo eliminated adds ~$40,000 to your purchase price
3. Increase your down payment — More down means a smaller mortgage to qualify
4. Choose 30-year amortization — Available for first-time buyers of new builds
5. Use a mortgage broker — Brokers access B-lenders with different qualifying criteria

Who Does the Stress Test Apply To?

All federally regulated lenders (major banks, federal credit unions). Some provincial credit unions may use different rules. Private lenders don't use the stress test at all, but charge higher rates.

Why the Stress Test Exists

OSFI introduced the stress test in 2018 to ensure Canadian homebuyers could still afford their mortgage if rates rose. It reduces how much Canadians can borrow by approximately 15–20% compared to qualifying at the actual mortgage rate.

How It Works

You qualify at the higher of: your rate + 2%, or 5.25%. Your payment at that higher rate must fit within GDS (39%) and TDS (44%) ratio limits.
