How Much Mortgage Can You Actually Qualify For in 2026?
TL;DR
Your max mortgage is set by whichever is lower: 39% of gross income going to housing (GDS) or 44% going to all debts (TDS). Then OSFI requires you to qualify at your contract rate +2% or 5.25%, whichever is higher. Run your scenario in our Mortgage Affordability Calculator.
Step 1 — The two ratios that gate every Canadian mortgage
Every federally-regulated Canadian lender uses the same two ratios from CMHC's underwriting playbook:
- GDS (Gross Debt Service): Housing costs (mortgage payment + property tax + heat + 50% of condo fee) divided by your gross monthly income. Maximum: 39%.
- TDS (Total Debt Service): GDS + all other monthly debt payments. Maximum: 44%.
Whichever ratio hits its cap first sets your real budget. For most Canadians without significant other debt, GDS is binding; for households with car loans or student loans, TDS usually is.
Step 2 — Then OSFI makes you qualify at a higher rate
Since 2018, the OSFI B-20 stress test requires lenders to qualify you at the higher of:
- Your contract rate + 2 percentage points, or
- 5.25%
So even if you've negotiated a 4.29% fixed rate, your lender approves you against a payment calculated at 6.29%. If you can't afford that payment under the GDS/TDS limits, you don't get the loan.
Step 3 — Worked example, $130K household income
Two earners pulling $80K and $50K = $130K combined gross. Toronto. $80K saved for down payment. $300/month car loan. Property tax $4,800/yr, heat $150/mo, no condo fee. Contract rate 4.99%, 25-year amortization.
- Gross monthly income: $10,833
- GDS budget (39%): $10,833 × 39% − $400 (tax) − $150 (heat) = $3,675/mo for mortgage
- TDS budget (44%): $10,833 × 44% − $300 (debt) − $400 − $150 = $3,917/mo for mortgage
- Lower of the two: $3,675 (GDS-bound)
- Qualifying rate: max(4.99% + 2%, 5.25%) = 6.99%
- Max mortgage at $3,675/mo and 6.99% over 25 years: ~$520,000
- Plus $80K down: ~$600,000 max purchase price
Step 4 — Why "approved for X" isn't your real budget
Just because the bank will give you $600K doesn't mean you should buy at that price. The GDS/TDS rules ignore real life: childcare, retirement contributions, vacation, job loss risk. Most planners suggest leaving 10–15% of cushion below your qualifying max — i.e., shopping in the $500–540K range here, not $600K.
Step 5 — Three levers that actually move your max
- Pay off small debts first. Killing a $300/month car loan adds roughly $50,000 to your max mortgage.
- 30-year amortization. Available again for first-time buyers on insured mortgages since 2024 — adds ~10% to qualifying max.
- Larger down payment. Beyond 20%, you skip CMHC insurance entirely (which can save $15K+ on a $500K mortgage).
