Why Mortgage Qualification Matters in Canada

Buying your first home in Canada is an exciting milestone — but it can also be overwhelming. While recent declines in average home prices and lower interest rates have made the market somewhat more accessible, qualifying for a mortgage remains the biggest hurdle for most buyers.

You may have saved for years for a down payment, but if you don’t understand how lenders assess your ability to repay a mortgage, your application could be denied — even with a sizable savings.

This guide breaks down the current mortgage qualification rules in Canada, explains each step with real examples, and gives practical advice to help entrepreneurs, small business owners, and freelancers succeed — with support from MB Tax Solutions.

Current Canadian Housing Market

• The average home price has declined by about 3.4% year-over-year (Canadian Real Estate Association).
• The Bank of Canada Rate dropped from 5.25% in July 2023 to 2.5% in October 2025, lowering borrowing costs.

How Lenders Assess Mortgage Applications

1⃣ Do You Have the Required Down Payment?

Purchase Price	Minimum Down Payment
Up to $500,000	5%
$500,000–$1.5M	5% on first $500K + 10% on amount over $500K
$1.5M or more	20%

Note: If your down payment is less than 20%, you’ll likely need Mortgage Loan Insurance (CMHC).

2⃣ GDS and TDS Ratios — What They Are and Why They Matter

Gross Debt Service (GDS) includes:

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

It must be ≤ 39% of your gross income.

Total Debt Service (TDS) includes all debts:

• Mortgage
• Car loans
• Credit cards
• Lines of credit
• Child/support obligations

It must be ≤ 44% of your gross income.

3⃣ The Mortgage Stress Test — A Critical Threshold

Introduced in 2018, the Stress Test ensures that borrowers can handle interest rate increases over time.

Lenders must evaluate your ability to meet GDS and TDS using the greater of:

• 5.25%
• Your contracted rate + 2%

As of October 2025, with average 5-year mortgage rates around 4.5%, the Stress Test is typically run at 6.5%.

Real Example

A couple seeks a $750,000 home with a $50,000 down payment.

• Income: $150,000/year
• Car loan: $400/month
• Taxes: $4,800/year
• Heating: $1,500/year
• Mortgage rate: 4.5%

GDS/TDS at Current Rate

• GDS: ~$46,800 mortgage + $6,300 taxes/heating = 35.4% of income
• TDS: + $4,800 car loan = 38.6% of income

Stress Test at 6.5%

• GDS: ~$56,400 mortgage + $6,300 = 41.8% (above limit)
• TDS: + $4,800 = 45.0% (above limit)

Result: This couple fails the stress test and may be denied a mortgage.

Practical Tips to Improve Your Odds

If TDS is too high:

• Pay down higher-interest debts
• Reduce credit card balances
• Avoid new debts

If GDS is the problem:

1. Increase income
2. Save more for a larger down payment
3. Choose a less expensive home

Caution: Avoid borrowing for a down payment unless it’s interest-free and non-repayable monthly.
