Everything you need to know about qualifying for a mortgage in 2025
The mortgage stress test is a financial qualification rule that requires all Canadian homebuyers to prove they can afford their mortgage payments at a higher interest rate than they're actually paying.
You must qualify at the higher of:
Example: If your actual mortgage rate is 4.59%, you must prove you can afford payments at 6.59% (4.59% + 2%).
The stress test was introduced by the federal government and banking regulator (OSFI) to protect both borrowers and the financial system.
Here's how lenders apply the stress test:
This is the actual interest rate you'll pay (e.g., 4.59%)
4.59% + 2% = 6.59%
Is 6.59% higher than 5.25%? Yes, so you qualify at 6.59%
Lender calculates what you can borrow at 6.59%, not 4.59%
Must also meet GDS (39%) and TDS (44%) requirements at qualifying rate
| Scenario | Without Stress Test | With Stress Test |
|---|---|---|
| Your Income | $80,000/year | $80,000/year |
| Actual Mortgage Rate | 4.59% | 4.59% |
| Qualifying Rate | 4.59% | 6.59% (4.59% + 2%) |
| Maximum Mortgage | ~$425,000 | ~$360,000 |
| Monthly Payment | $2,480 at 4.59% | $2,096 at 4.59% |
| Difference | $65,000 less borrowing power | |
Down payment less than 20% (requires CMHC insurance)
Down payment 20%+ at federally regulated lenders
Switching lenders or increasing mortgage amount
Applies to everyone equally
The stress test significantly reduces how much you can borrow. Here's how different income levels are affected:
| Annual Income | Without Stress Test | With Stress Test | Reduction |
|---|---|---|---|
| $60,000 | $320,000 | $270,000 | -$50,000 (16%) |
| $80,000 | $425,000 | $360,000 | -$65,000 (15%) |
| $100,000 | $530,000 | $450,000 | -$80,000 (15%) |
| $150,000 | $795,000 | $675,000 | -$120,000 (15%) |
Assumptions: 25-year amortization, 20% down payment, no other debts, property tax of 1%
On average, the stress test reduces your borrowing power by 15-20%. This means if you could have qualified for a $500,000 mortgage before, you now qualify for approximately $425,000.
Larger down payment = smaller mortgage needed = easier to qualify
Example: $500k home with $125k down (25%) vs $100k down (20%)
Eliminate car loans, credit cards, student loans to improve TDS ratio
Impact: Paying off $500/month in debts = ~$80k more borrowing power
Ask for a raise, work overtime, add co-borrower income
Tip: Both spouses/partners can combine income
25-year vs 20-year = lower monthly payments = easier to qualify
Note: 30 years available with 20%+ down
Better credit = better rates = easier to qualify
Target: 680+ (good), 760+ (excellent)
Sometimes the only option - consider starter homes or different neighborhoods
If buying a property with rental suite, some lenders count 50% of rental income

| Lender Type | Stress Test? | Interest Rates | Trade-offs |
|---|---|---|---|
| Big Banks | Yes, always | Lowest (4-6%) | Strict qualification |
| Provincial Credit Unions | Varies by province | Low-Medium (4-7%) | Regional availability |
| B-Lenders | Modified or no | Medium (6-9%) | Higher fees, shorter terms |
| Private Lenders | No | High (8-15%+) | Very expensive, last resort |
The stress test is reviewed periodically by the federal government and OSFI. Here's what could happen:
| Arguments For Keeping/Strengthening | Arguments For Reducing/Removing |
|---|---|
| Protects borrowers from over-leveraging | Locks out qualified buyers, especially first-timers |
| Reduces risk of defaults and foreclosures | Doesn't account for individual financial discipline |
| Stabilizes housing market | Reduces market liquidity and activity |
| Worked during 2020-2023 rate hikes | Disproportionately affects lower income buyers |
| Prevents mortgage debt crisis | Forces people to rent longer, missing market gains |
Most economists and regulators believe the stress test should remain in some form, but there's debate about the specific parameters. The government reviews it annually and makes adjustments based on economic conditions.
