How Much House Can I Afford in Canada?
Quick Answer
How Much House Can I Afford in Canada?
In Canada, you can typically afford a home priced at 4 to 5 times your gross annual household income, provided your total monthly housing costs (Gross Debt Service ratio) stay under 32% of gross monthly income and total debt payments (Total Debt Service ratio) stay under 40%. A $100,000 income generally supports a $400,000–$500,000 home with a 20% down payment.
Detailed Explanation
How Much House Can I Afford in Canada?
Determining how much house you can afford in Canada depends on several key factors: your gross annual income, your down payment amount, your existing monthly debt obligations, and current mortgage interest rates.
Canadian lenders use two key ratios to determine affordability:
Gross Debt Service (GDS) Ratio
Your GDS ratio measures your monthly housing costs as a percentage of your gross monthly income. Most Canadian lenders require this ratio to be 32% or less. Housing costs include:
- Mortgage principal and interest payments
- Property taxes
- Heating costs
- 50% of condo fees (if applicable)
Total Debt Service (TDS) Ratio
Your TDS ratio measures all your monthly debt obligations as a percentage of gross monthly income. Most lenders require this to be 40% or less. This includes all GDS costs plus:
- Car loan payments
- Credit card minimum payments
- Line of credit payments
- Student loan payments
- Any other debt obligations
The Stress Test
All Canadian mortgages must pass the stress test. You must qualify at a rate that is the higher of:
- The Bank of Canada's 5-year benchmark rate, or
- Your contractual mortgage rate plus 0.5%
This means your affordability is calculated at a higher rate than you'll actually pay, ensuring you can handle rate increases.
How It Is Calculated
How Affordability Is Calculated
Step 1: Calculate Gross Monthly Income
Annual Income / 12 = Monthly Income
For a household earning $120,000/year:
- Monthly gross income = $120,000 / 12 = $10,000
Step 2: Apply GDS Ratio (32% max)
Monthly Income x 0.32 = Max Monthly Housing Costs
$10,000 x 0.32 = $3,200 maximum monthly housing costs
Step 3: Subtract Non-Mortgage Housing Costs
Deduct estimated property taxes, heating, and condo fees:
- Property taxes: ~$400/month
- Heating: ~$150/month
- Remaining for mortgage: $3,200 - $550 = $2,650/month
Step 4: Calculate Maximum Mortgage
Using the stress test rate and a 25-year amortization, $2,650/month supports approximately:
- At 5.5% stress test rate: ~$440,000 mortgage
Step 5: Add Down Payment
- With 20% down ($110,000): Max purchase price approx. $550,000
- With 5% down ($27,500): Max purchase price approx. $467,500 (plus CMHC insurance)
Example
Example: $120,000 Household Income in Toronto
Scenario: A couple with combined gross income of $120,000, $60,000 saved for down payment, no other debts.
| Factor | Value |
|---|---|
| Gross monthly income | $10,000 |
| Max GDS (32%) | $3,200/month |
| Estimated property tax | $350/month |
| Estimated heating | $150/month |
| Available for mortgage | $2,700/month |
| Stress test rate | ~5.5% |
| Max mortgage (25-year amort.) | ~$449,000 |
| Down payment (20%) | $112,250 |
| **Max purchase price** | **~$561,000** |
Note: In Toronto, this budget limits options to condos or properties outside the core. Land transfer tax (provincial + municipal) adds ~$16,000 in closing costs. First-time buyers receive up to $4,000 LTT rebate.
With 5% down ($28,050): Max purchase price drops to ~$477,000, plus ~$19,000 CMHC insurance added to the mortgage.
