• Qualifying ratios: GDS 35% max, TDS 42% max.
• Stress test rate: higher of contract rate + 2% or 5.25% — this is what lenders use for qualification.
• Heating costs default to $120/month (average). Property tax defaults to $350/month.
• 50% of condo fees are included in GDS calculation per CMHC guidelines.
• Actual qualification depends on credit score, employment history, and lender-specific criteria.
How Much Income Do You Need to Buy a Home in Canada?
One of the most important questions when buying a home is: "Do I earn enough?" Lenders in Canada use two key ratios — GDS and TDS — to determine whether your income supports the mortgage you're applying for. This calculator shows you exactly how much gross annual income you need based on current CMHC qualifying rules and the federal stress test.
GDS vs TDS: What Lenders Look For
The Gross Debt Service (GDS) ratio measures what percentage of your gross monthly income goes toward housing costs: mortgage payment, property taxes, heating, and half of condo fees (if applicable). For insured mortgages (less than 20% down), GDS must not exceed 32%. For conventional mortgages, the limit is 35%.
The Total Debt Service (TDS) ratio adds all other monthly obligations on top of housing costs — car loans, credit card payments, student loans, personal loans, and child support payments. TDS is capped at 40% for insured mortgages and 42% for conventional. TDS is often the binding constraint for borrowers with significant existing debt.
The Stress Test Impact
Since 2018, all insured mortgages and most conventional mortgages must qualify at the Bank of Canada's stress test rate — the higher of your contract rate plus 2 percentage points or 5.25%. This means if your actual mortgage rate is 4.79%, you must qualify as if the rate were 6.79%. The stress test adds approximately $300-500/month to the qualifying payment on a typical mortgage, increasing the income needed by $10,000 to $20,000 per year.
What Counts as Income
- Base salary: Full-time guaranteed income — most straightforward to qualify with.
- Overtime & bonus: Typically averaged over 2 years; must be consistent and documented.
- Commission: Averaged over 2 years with T4s or NOAs to verify.
- Rental income: Usually 50% of net rental income added to qualifying income (some lenders use 100% with offset).
- Self-employed: Based on net income from Line 15000 of tax returns, averaged over 2-3 years.
- Investment & pension: Can qualify if consistent and documented.
How to Improve Your Qualifying Power
If the calculator shows you need more income than you have, there are several strategies. First, pay down existing debts — reducing a $400/month car payment to $0 can increase your qualifying power by roughly $80,000 in mortgage amount. Second, increase your down payment, which reduces the mortgage and potentially eliminates CMHC (shifting you to more lenient conventional ratios). Third, consider a longer amortization (30 years) to lower the monthly payment. Fourth, a co-signer or joint applicant adds their income to the qualification. Finally, shop around — some lenders have flexibility on ratios, especially for borrowers with strong credit or unique income structures.
