How the Canadian Affordability Formula Works
Mortgage qualification in Canada isn't just about your credit score; it's a mathematical calculation of your Gross Debt Service (GDS) and Total Debt Service (TDS) ratios.
GDS = (Principal + Interest + Taxes + Heat) / Gross IncomeTDS = (PITH + Other Debts) / Gross Income
The 2026 Mortgage Stress Test Explained
Even if you secure a 4% interest rate, the Office of the Superintendent of Financial Institutions (OSFI) requires lenders to "stress test" your finances at a higher rate. This ensures that if rates rise to 6% or higher, you can still maintain your payments. Our tool automatically applies these B-20 regulations to give you a realistic borrowing limit.
Case Study: $100,000 Household Income
If a household earns $100,000 CAD per year with no car loans or credit card debt, their maximum monthly housing expense (GDS at 39%) would be approximately $3,250. After subtracting property taxes and heating, the remaining amount determines the maximum mortgage principal they can carry.
Frequently Asked Questions
Can I use a 30-year amortization?
In 2026, 30-year amortizations are typically reserved for uninsured mortgages (20% down payment or more) or specific new-construction incentives. High-ratio insured mortgages are still capped at 25 years.
How do condo fees affect my affordability?
Lenders generally include 50% of your monthly condo fees into your GDS/TDS calculations. This significantly reduces the mortgage amount you can qualify for compared to a freehold house.
