Quick answer

Will I pass the Canadian mortgage stress test in 2026?

Federally regulated lenders qualify you at the greater of (a) your contract rate plus 2 percentage points, or (b) the 5.25 percent benchmark — whichever is higher. You must pass two ratios: GDS (housing costs) ≤ 39 percent and TDS (all debt) ≤ 44 percent of gross monthly income. Since late 2024, renewals at the same lender no longer require the stress test.

Will I Pass the Canadian Mortgage Stress Test?

The OSFI B-20 stress test decides how much mortgage you actually qualify for.

The rule: Federally regulated lenders must qualify you at the greater of (a) your contract rate plus 2 percentage points, or (b) the 5.25 percent benchmark rate — whichever is higher.

Two ratios you must pass

  • GDS (Gross Debt Service): mortgage payment + property tax + heat + half of condo fees, all ÷ gross monthly income, must be ≤ 39 percent.
  • TDS (Total Debt Service): GDS items + car loans + credit-card minimums + student loans + line of credit payments, ÷ gross monthly income, must be ≤ 44 percent.

Quick example

Household earns $110,000 = $9,167/month gross. Contract rate is 4.59 percent → stress-tested rate = 6.59 percent. With $80,000 down on a 25-year amortization and $450/month in other debts:

  • Max payment from GDS = $9,167 × 0.39 − ($350 tax/mo) − ($120 heat) = $3,105
  • Max payment from TDS = $9,167 × 0.44 − $470 − $450 = $3,113
  • Binding limit: ~$3,105. At 6.59 percent over 25 years that supports a mortgage of about $435,000 → home price around $515,000.

Down payment minimums

  • Under $500,000: 5 percent
  • $500K–$1.5M: 5 percent on first $500K + 10 percent on the rest
  • $1.5M+: 20 percent minimum, no CMHC insurance available
  • Insured (under 20 percent down) requires CMHC, Sagen, or Canada Guaranty premium added to the mortgage

Who must pass the stress test?

All federally regulated lenders (the Big 6 banks + most credit unions) require the test for both new buyers and renewals if you switch lenders. Sticking with your current lender at renewal — no stress test required as of late 2024.
