If you read nothing else
- Lenders do not just look at your salary. They factor in your existing debts, the stress test, and your full financial picture.
- The mortgage stress test means you need to qualify at a higher rate than you will actually pay.
- As a general rule, housing costs should not exceed 39% of your gross monthly income.
- Two incomes can change the picture significantly. Buying with a partner opens doors that a single income may not.
Priya is 29, earning $72,000 a year in marketing, and renting a one-bedroom apartment in Toronto. She has been reading the headlines about housing affordability for young Canadians and wants to know what income she would actually need to buy a home. This article is a guide for anyone in a situation like Priya's.
How Lenders Actually Calculate What You Can Afford
This is where the Gross Debt Service ratio and Total Debt Service ratio come in. Think of them as budgeting rules lenders use to determine whether a mortgage payment is likely to be affordable.
The GDS ratio looks at your monthly housing costs as a percentage of your gross monthly income. Lenders typically look for a GDS of 39% or less. For Priya, earning $6,000 per month, 39% works out to $2,340. That budget covers not just the mortgage payment but also property taxes, heating costs, and if she is buying a condo, a portion of the monthly condo fees.
The TDS ratio adds any other monthly debt payments, such as car loans or student loans, to the GDS calculation. Lenders typically look for a TDS of 44% or less. For Priya, that means her total housing costs plus other monthly debt payments would generally need to stay around $2,640.
The Stress Test Factor
The mortgage stress test requires Canadian borrowers to qualify at a rate higher than their actual mortgage rate, proving they can handle potential rate increases. For Priya, this means the income required to qualify is higher than the income required to simply make the payments. The stress test applies to every new mortgage application regardless of the borrower's history.
What Does This Look Like Across Different Canadian Cities?
Priya has broadened her search beyond Toronto. Here is what the income requirement looks like in major Canadian cities based on benchmark average home prices from CREA as of June 2026.
| Benchmark Price | Estimated Income Required | |
|---|---|---|
| Toronto | $940,800 | Approximately $195,000 |
| Vancouver | $1,203,000 | Approximately $235,000 to $250,000 |
| Calgary | $520,000 to $650,000 | $130,000 to $145,000 |
| Ottawa | $520,000 to $650,000 | $130,000 to $145,000 |
| Halifax | $460,000 to $575,000 | $115,000 to $130,000 |
$195,000

What If Your Income Is Not There Yet?
Priya feels overwhelmed by some of these numbers. But there are options worth knowing about.
A co-borrower or partner allows two incomes to be combined, which can significantly change the qualifying amount. A larger down payment reduces the mortgage required, which lowers the income threshold. The First Home Savings Account is a registered account designed to help first-time buyers save for a down payment, with contributions being tax-deductible and growth tax-free.
Different markets and property types are also worth considering. Housing in Canada varies significantly by city, neighbourhood, and property type. A condo in Halifax requires a very different income than a detached home in Vancouver.
When to Talk to a Mortgage Broker
A broker can give Priya a real pre-approval number based on her actual financial picture, not a general estimate. That conversation is the most useful first step for anyone trying to understand what they can actually afford and what they are working toward.
