What is the mortgage stress test in Canada?

The stress test requires borrowers to qualify at a higher interest rate than their actual mortgage rate. You must prove you can afford payments at the higher of 5.25% or your contract rate plus 2%. This ensures borrowers can handle rate increases.

What is the stress test rate in 2026?

The stress test qualifying rate is the higher of 5.25% (the floor) or your contract rate plus 2%. If your mortgage rate is 5%, you qualify at 7%. If your rate is 3%, you qualify at 5.25% (the floor applies).

How much does the stress test reduce my buying power?

The stress test typically reduces purchasing power by 15-25%. A buyer who could qualify for $600,000 based on actual payments might only qualify for $480,000-$510,000 under the stress test.

Can I avoid the stress test?

No. The stress test applies to all insured mortgages (less than 20% down) and most uninsured mortgages from federally regulated lenders. Some credit unions and private lenders don't apply it, but these often have higher rates.

Rate used	5.00%	7.00%
Max mortgage	$580,000	$480,000
Reduction	—	-$100,000

Maximum Mortgage by Income

Assuming 25-year amortization, 39% GDS, and stress test rate of 7%:

Household Income	Max Mortgage	With 20% Down = Home Price
$60,000	$285,000	$356,000

How Banks Apply the Stress Test

Step 1: Calculate Stressed Payment

Mortgage	$500,000
Contract rate	5.00%
Stress test rate	7.00%
Actual payment (25yr)	$2,908/month
Stressed payment	$3,499/month

Step 2: Check Debt Ratios

Using the stressed payment:

Ratio	Limit	Calculation
GDS	39%	(Mortgage + Tax + Heat) ÷ Income
TDS	44%	(GDS + Other Debts) ÷ Income

Passing the Stress Test

Increase Buying Power

Strategy	Impact
Larger down payment	Reduces mortgage needed
Pay off debts	Lowers TDS ratio
Add co-borrower	Increases qualifying income
30-year amortization	Lower stressed payment*
Buy with lower taxes	Reduces GDS

*30-year amortization only available with 20%+ down

Impact of Down Payment Size

Home Price	Down Payment	Mortgage	Can Qualify?
$600,000	$30,000 (5%)	$570,000	Need ~$118K income
$600,000	$60,000 (10%)	$540,000	Need ~$112K income
$600,000	$120,000 (20%)	$480,000	Need ~$100K income

Stress Test with Different Amortizations

$500,000 mortgage at 7% stress test rate:

Amortization	Stressed Payment	Income Needed
20 years	$3,872/month	$125,000
25 years	$3,499/month	$112,000
30 years	$3,272/month	$103,000

Why the Stress Test Exists

The stress test was introduced to:

Protect borrowers from rate increases
Reduce risky lending
Cool overheated housing markets
Ensure financial stability

Without it, a 2% rate increase could make mortgage payments unaffordable for many Canadians.
