What is the Stress Test?
A mortgage stress test is a regulatory requirement that ensures borrowers can afford mortgage payments even if interest rates rise in the future.
Why the Stress Test Matters in Real Estate
In Canada, all federally regulated lenders must apply a stress test to mortgage applicants, whether they are buying, refinancing, or switching lenders.
Borrowers must qualify at the greater of:
- The contracted mortgage rate + 2%
- The Bank of Canada’s benchmark qualifying rate
The stress test reduces the maximum loan amount a borrower can qualify for. It’s designed to protect both borrowers and the financial system from overleveraging during rate increases.
Understanding the stress test helps buyers calculate realistic budgets and avoid surprises during mortgage approval.
Example of the Stress Test in Action
A borrower applies for a 4.6% mortgage but must qualify at 6.6% under the stress test, reducing their purchasing power by $50,000.

National average resale-price growth and housing-starts growth, smoothed over three months. The comparison illustrates the cycle; it does not establish how much a price change causes construction to change.
Trailing 12-month starts in centres of 50,000 or more remove the usual monthly seasonality. Ownership combines the homeowner and condominium categories; rental is shown separately.
Six-month averages of provincial starts, expressed at annual rates. The smoothing reduces the influence of individual apartment projects.
The same August benchmark compared with two different starting points. Three-month changes are not annualized.
Average sale prices show the difference in purchase costs across markets. They do not measure affordability relative to local incomes or construction costs.
Newfoundland and Labrador remains above its pre-pandemic sales pattern, but August activity was below last year. Historical lines retain their original release vintages.
Average and median describe different aspects of the same month’s transactions. Both are affected by the mix of homes sold.
Category averages compare different homes and locations; the gaps are not estimates of the cost to upgrade an otherwise identical property.
The five categories shown account for 5,000 of the board’s 5,057 sales. The remaining 57 transactions were in other housing categories.
Monthly observations are not seasonally adjusted. Active listings count properties available at month-end; they are not construction inventory.
Average and median prices share one dollar axis. These unadjusted transaction measures do not control for changes in the homes sold.
TRREB’s 416/905 categories compare the apartments sold in each area. The difference does not isolate a location premium for equivalent units.
