Mortgage Stress Test in Ontario: How Much Income Do You Actually Need?

A complete breakdown of income requirements for Ontario home buyers in 2026

February 15, 2026 7 min read

The mortgage stress test is one of the most important—and often misunderstood—aspects of buying a home in Ontario. Implemented by the federal government to ensure borrowers can handle higher interest rates, the stress test determines how much income you need to qualify for a mortgage.

In this guide, we'll break down exactly how the stress test works, what income is required for different price points, and how factors like condo fees and existing debt impact your qualification.

How the Stress Test Works

The mortgage stress test requires borrowers to qualify at a rate higher than their actual mortgage rate. This ensures you can still afford payments if rates increase in the future.

The Two Stress Test Rules

  • 1
    Contract Rate + 2%

    You must qualify at your actual mortgage rate plus 2 percentage points. For example, if your negotiated rate is 5.50%, you must prove you can afford payments at 7.50%.

  • 2
    Bank of Canada Benchmark Rate (5.25% as of Feb 2026)

    Alternatively, you must qualify at the BoC's benchmark rate, whichever is higher. This rate is updated periodically by the Bank of Canada.

Note: The stress test applies to all mortgages with federally regulated lenders (banks, credit unions). Provincial lenders and private lenders may have different requirements.

Example: $700,000 Purchase

A $700,000 home is common for first-time buyers in Ontario outside the GTA. Here's exactly how much income you need to qualify.

Assumptions

  • • Purchase Price: $700,000
  • • Down Payment: 20% ($140,000)
  • • Mortgage Amount: $560,000
  • • Interest Rate: 5.50% (30-year amortization)
  • • Property Taxes: $3,500/year
  • • Heating: $150/month

Income Required at Stress Test Rate

Mortgage Payment at 5.50% $3,176/month
Mortgage Payment at 7.50% (Stress Test) $3,927/month
Property Taxes $292/month
Heating $150/month
Total Monthly Payment $4,369/month

Minimum Income Required

To pass the stress test with a 39% TDS ratio (maximum allowed), you need a minimum annual income of approximately $134,000.

This assumes you have no other debt (car payments, credit cards, etc.)

Example: $1 Million Purchase (GTA)

A $1 million home is entry-level in the Greater Toronto Area. Here's the income required to qualify in Ontario's most competitive market.

Assumptions

  • • Purchase Price: $1,000,000
  • • Down Payment: 20% ($200,000)
  • • Mortgage Amount: $800,000
  • • Interest Rate: 5.50% (30-year amortization)
  • • Property Taxes: $6,000/year
  • • Heating: $150/month

Income Required at Stress Test Rate

Mortgage Payment at 5.50% $4,537/month
Mortgage Payment at 7.50% (Stress Test) $5,610/month
Property Taxes $500/month
Heating $150/month
Total Monthly Payment $6,260/month

Minimum Income Required

To pass the stress test with a 39% TDS ratio (maximum allowed), you need a minimum annual income of approximately $192,500.

This assumes you have no other debt. Any car payments, credit card debt, or student loans will increase this requirement.

Effect of Condo Fees on Qualification

Condo fees can significantly impact your mortgage qualification. Unlike property taxes and heating, condo fees are added directly to your debt calculations.

How Condo Fees Affect TDS

Condo fees are included in your Total Debt Service (TDS) ratio calculation, which means they directly reduce how much income is available for your mortgage payment.

Monthly Condo Fee Additional Income Needed ($700K Home) Additional Income Needed ($1M Home)
$300/month +$9,230/year +$13,200/year
$500/month +$15,380/year +$22,000/year
$700/month +$21,540/year +$30,800/year
$1,000/month +$30,770/year +$44,000/year

Important: Condo fees can increase over time. Lenders may also factor in a 10% buffer for potential fee increases when calculating your qualification.

Debt-to-Income Limits

Lenders use two key ratios to determine how much mortgage you can afford: GDS and TDS. Understanding these limits is crucial for passing the stress test.

GDS Ratio

Gross Debt Service measures your housing costs as a percentage of gross income.

39%

Maximum allowed

  • • Mortgage payment
  • • Property taxes
  • • Heating costs
  • • 50% of condo fees (if applicable)

TDS Ratio

Total Debt Service includes all debts plus housing costs.

44%

Maximum allowed

  • • Everything in GDS
  • • Car payments
  • • Credit card debt
  • • Student loans
  • • Other loans

Pro Tip

Lenders typically prefer ratios below 36% (GDS) and 42% (TDS) for the best rates. Staying below these thresholds gives you more flexibility.

Bank of Canada Reference

The mortgage stress test rules are set by the federal government, with the Bank of Canada playing a key role in determining the benchmark rate used for qualification.

Key Points from the Bank of Canada

  • Benchmark Rate: The Bank of Canada publishes a benchmark rate (currently 5.25% as of February 2026) that serves as the minimum stress test rate for uninsured mortgages.
  • Rate Updates: The benchmark rate is reviewed quarterly and can change based on prevailing market conditions. Changes take effect immediately for new mortgage applications.
  • Policy Tool: The stress test is a macroprudential tool designed to ensure financial stability by preventing borrowers from taking on too much debt.
  • Impact on Buyers: The BoC's rate decisions directly affect your buying power. Lower benchmark rates mean easier qualification; higher rates mean more income is required.
