Housing affordability is a major topic for Canadians in 2025, as rising home prices and fluctuating mortgage rates continue to challenge buyers across the country. Understanding housing affordability indexes and mortgage stress tests is essential for first-time buyers, investors, and anyone planning to purchase property this summer. These tools provide insight into how much home you can realistically afford while helping lenders assess risk in the current market.
What Is the Housing Affordability Index in Canada?
The housing affordability index (HAI) is a measure of whether a typical family can afford a median-priced home in their region. An HAI of 100 means a household earning the median income can exactly afford the mortgage, property taxes, and utilities for a median-priced home. Values above 100 indicate homes are more affordable, while below 100 suggests a squeeze on buyers’ budgets.
In 2025, affordability varies widely across Canadian cities:
- Toronto and Vancouver continue to experience tight affordability, with indexes below 90, reflecting high home prices relative to incomes.
- Calgary, Edmonton, and Ottawa remain more accessible, with HAIs above 120 in some neighborhoods, showing that households can comfortably manage mortgage payments.
The HAI accounts for mortgage rates, local taxes, utilities, and average household income, making it a practical tool for comparing affordability across regions. This summer, fluctuating interest rates have slightly eased affordability pressures for some buyers, but in high-demand markets like Toronto, purchasing a home still requires careful financial planning.
Mortgage Stress Tests Explained
A mortgage stress test ensures that potential homebuyers can manage their payments if interest rates rise. In Canada, the Office of the Superintendent of Financial Institutions (OSFI) sets the benchmark for these tests. As of Summer 2025:
- Borrowers must qualify at the greater of the Bank of Canada’s five-year benchmark rate or their contracted mortgage rate plus 2%.
- This test helps lenders reduce the risk of defaults during rising rate environments and ensures buyers are financially resilient.
For example, if your mortgage rate is 6%, your lender will calculate your monthly payment using 8% (6% + 2%) to confirm affordability. This means you may qualify for a smaller mortgage than expected, even if your income seems sufficient under today’s lower rates.

Regional Differences in Stress Test Impact
Mortgage stress tests affect Canadian buyers differently depending on the city:
- Toronto & Vancouver: Stress tests limit borrowing capacity in an already expensive market, keeping monthly payments manageable but reducing purchasing power.
- Calgary & Ottawa: Stress tests are less restrictive due to lower home prices, allowing buyers to access larger mortgages relative to income.
- Halifax & Montreal: Moderate impact; affordability indexes are reasonable, but buyers still need to account for potential interest rate hikes.
Understanding these regional variations is key for Canadians planning to purchase this summer. Homebuyers should use mortgage calculators and affordability tools to assess realistic options.
Tips for Buyers This Summer
- Check Your Affordability: Use the HAI to compare cities or neighborhoods before making offers.
- Plan for Rising Rates: Stress tests assume higher rates, so budget for future payment increases.
- Consider Alternative Financing: Co-buying or larger down payments can improve borrowing power.
- Consult Professionals: Mortgage brokers and financial advisors can help interpret stress test results and identify best neighborhoods for affordability.
Final Thoughts
Canada’s housing market in Summer 2025 continues to challenge buyers, but understanding housing affordability indexes and mortgage stress tests can empower informed decisions. While Toronto and Vancouver remain expensive, smaller urban centers and suburban neighborhoods offer more accessible opportunities. By planning carefully, factoring in stress test results, and comparing HAI values across regions, buyers can make confident choices without overextending financially. Keeping an eye on mortgage rates, government incentives, and regional market trends will ensure a smooth buying experience, whether it’s your first home or an investment property. Using these tools strategically can help Canadians balance aspiration with financial reality in the current housing landscape.
