How Much Mortgage Can I Afford on My Salary in Canada?
In Canada, the mortgage you can afford on your salary is determined by two ratios set by lenders — the Gross Debt Service (GDS) ratio and the Total Debt Service (TDS) ratio — and the federal mortgage stress test, which requires you to qualify at a rate roughly 2% above what you'll actually pay. On a $90,000 salary with no other debt and 20% down, you can typically qualify for a mortgage of approximately $454,000; on a $70,000 salary with a 30% down payment and no other debt, the maximum is around $305,230. This guide explains exactly how the calculation works and how to estimate your own mortgage affordability before speaking with a lender.
Disclaimer: This is general information, not personalized financial advice. Your exact qualifying amount depends on your full debt profile, credit score, down payment, property taxes, and which lender you approach. Confirm your specific numbers with a licensed mortgage professional before making any purchase decisions.
The Two Ratios That Determine What You Can Borrow
Canadian lenders use two debt-service ratios to determine how much mortgage you can qualify for — the GDS ratio and the TDS ratio — and you must stay within both limits simultaneously.
- Gross Debt Service (GDS) ratio: The percentage of your gross monthly income that goes toward housing costs — specifically your mortgage payment (principal + interest), property taxes, heating costs, and 50% of condo fees if applicable. The maximum GDS ratio under CMHC guidelines is 39%. A GDS of 32% or below is considered conservative and gives you more breathing room.
- Total Debt Service (TDS) ratio: Everything in GDS, plus all other monthly debt payments — car loans, student loans, credit card minimums, lines of credit. The maximum TDS ratio under CMHC guidelines is 44%. A TDS of 40% or below is considered strong. Every $500/month in non-mortgage debt payments reduces your maximum mortgage by approximately $80,000–$100,000.
Both ratios are calculated using the stress test qualifying rate, not your actual contract rate — which means your lender is effectively testing your ability to handle a higher payment than you'll actually make on day one.
The Mortgage Stress Test: How It Reduces Your Borrowing Power
Canada's mortgage stress test requires every borrower at a federally regulated lender to qualify at the higher of their contract rate plus 2%, or the floor rate of 5.25%. In the current rate environment — where the best 5-year fixed insured rates are around 4.04%–4.49% as of mid-2026 per Ratehub.ca — the operative test is contract rate plus 2%, putting the qualifying rate for most borrowers in the range of 6.04%–6.49%.
This means even though you might actually make payments at 4.2%, your lender runs the GDS and TDS calculations at 6.2% or higher. The practical effect: you can afford to borrow considerably less than a simple calculation at your contract rate would suggest. A lower contract rate makes the stress test easier to pass — every 0.10% reduction in your contract rate meaningfully increases your qualifying mortgage amount.
Important exemptions: the stress test applies to new mortgages and refinancing at federally regulated lenders. If you are simply renewing with your current lender (same-lender renewal), the stress test does not apply — a significant protection if your financial situation has changed since you originally qualified. Credit unions and provincially regulated lenders are also exempt, though many voluntarily apply their own version of the test.
How Much Mortgage Can You Afford by Salary Level?
The table below shows approximate maximum mortgage and purchase prices at common income levels in Canada, based on a 5-year fixed qualifying rate of 6.44% (contract rate 4.44% + 2%), 25-year amortization, 20% down payment, no other debts, and a GDS limit of 39% with $500/month assumed for property tax and heating combined. These are directional estimates from WealthNorth's April 2026 stress test analysis — actual maximums vary with your full debt load, property taxes, and lender.
| Gross Annual Income | Approx. Max. Mortgage (20% down, no other debt) | Approx. Max. Purchase Price |
|---|---|---|
| $50,000 | ~$195,000 | ~$244,000 |
| $70,000 | ~$273,000–$305,000 | ~$341,000–$381,000 |
| $90,000 | ~$350,000–$454,000 | ~$438,000–$568,000 |
| $120,000 | ~$467,000–$600,000 | ~$584,000–$750,000 |
| $150,000 | ~$584,000–$750,000 | ~$730,000–$938,000 |
| $200,000 | ~$780,000–$1,000,000 | ~$975,000–$1,250,000 |
Ranges reflect variation between conservative (GDS ~32%) and maximum CMHC-guideline (GDS 39%) qualification. The $70,000 income / $305,230 purchase example is from Ratehub.ca's affordability calculator (30% down payment, no significant debt, located in Toronto, Ontario). The $90,000 income / $454,000 purchase example (20% down) is from lendsimpl's April 2026 stress test analysis using a 6.39% qualifying rate. The broader ranges are based on WealthNorth's April 2026 stress test income table using a 6.44% qualifying rate.

What Reduces Your Qualifying Amount
Several factors can meaningfully reduce the mortgage you qualify for, even with the same salary.
- Existing debt: Every $500/month in non-mortgage debt payments (car loan, student loan, credit card minimums) reduces your maximum mortgage by approximately $80,000–$100,000, because it raises your TDS ratio. Paying off high-interest debt before applying is one of the most effective ways to increase your qualifying amount.
- Less than 20% down payment: With less than 20% down, CMHC insurance is required and the insured mortgage cap is $1.5 million. The insurance premium (2.8%–4.0% of the mortgage amount) is added to your loan balance, increasing your total debt — which can slightly reduce the purchase price you can qualify for.
- Higher property taxes or condo fees: These feed directly into the GDS ratio. A condo with $800/month in fees counts at $400/month toward your GDS calculation, meaningfully reducing how much mortgage room you have for the same income.
- Variable income or self-employment: Salaried income is the easiest to document. Commission, bonus, or self-employed income is often averaged over 2 years by lenders, and may be discounted depending on stability — meaning the income number a lender uses in your GDS/TDS calculation may be lower than what you actually earn in a good year.
- Credit score below 680: A minimum credit score of 680 is required from at least one borrower for insured mortgages (less than 20% down). Below this, your options narrow to non-insured or alternative lenders, who typically charge higher rates — which in turn raises the stress test qualifying rate and reduces what you can borrow.
What Can Increase Your Qualifying Amount
- Adding a co-borrower: Combining incomes in the GDS/TDS calculation is the most powerful single lever. Two people each earning $75,000 qualify on $150,000 combined income — nearly doubling the mortgage a single $75,000 earner would qualify for.
- Paying down debt before applying: Reducing or eliminating a car loan or student loan before applying directly lowers your TDS ratio and can increase your qualifying mortgage by $80,000–$100,000 per $500/month in debt eliminated.
- Choosing a 30-year amortization: For qualifying first-time buyers and buyers of newly built homes, a 30-year insured amortization lowers the qualifying monthly payment, which improves your GDS ratio and increases your maximum qualifying amount. However, you pay considerably more interest over the life of the loan.
- Shopping for a lower contract rate: Because the stress test is your contract rate plus 2%, a lower contract rate directly lowers the qualifying rate. Every 0.25% reduction in your rate meaningfully improves what you can borrow. Compare rates across multiple lenders rather than accepting the first offer.
- Larger down payment: A larger down payment reduces the mortgage amount you need to qualify for, making it easier to pass both the GDS and TDS tests — and eliminates CMHC insurance entirely once you reach 20% down.

Frequently Asked Questions About Mortgage Affordability in Canada
How much mortgage can I afford on a $100,000 salary in Canada?
On a $100,000 gross annual salary with 20% down, no other debt, and a 25-year amortization, you can typically qualify for a mortgage of approximately $390,000–$500,000, depending on property taxes, heating costs, and which lender you use. The range reflects the difference between a conservative 32% GDS target and the maximum 39% CMHC guideline. These are directional estimates — confirm your specific number with a lender or use our Affordability Calculator.
What is the mortgage stress test in Canada?
Canada's mortgage stress test requires borrowers at federally regulated lenders to qualify at the higher of their contract rate plus 2%, or the floor rate of 5.25%. As of mid-2026, with best 5-year fixed rates around 4.04%–4.49%, the operative qualifying rate for most borrowers is approximately 6.04%–6.49%. This means you must demonstrate you could still afford your payments if rates were roughly 2% higher than your actual contract rate. Same-lender mortgage renewals are exempt from the stress test.
Does existing debt reduce how much mortgage I can get?
Yes, significantly. Every $500/month in non-mortgage debt payments — car loans, student loans, credit card minimums, lines of credit — raises your Total Debt Service (TDS) ratio and reduces your maximum qualifying mortgage by approximately $80,000–$100,000. Paying down high-interest debt before applying for a mortgage is one of the most effective ways to increase what you can qualify for.
Is mortgage affordability the same as mortgage qualification?
No, and the distinction matters. Mortgage qualification is the maximum a lender will legally approve based on your income, debts, credit, and the stress test. Mortgage affordability is the amount you can comfortably repay without sacrificing your other financial priorities — saving for retirement, building an emergency fund, covering unexpected expenses. These two numbers are often different, and buying at the maximum you can qualify for is not the same as buying what you can comfortably afford. A GDS ratio below 32% and TDS ratio below 40% are generally considered conservative, healthy starting points.
How does a co-borrower affect my mortgage qualification?
Adding a co-borrower combines both incomes in the GDS and TDS calculations, which is the single most powerful lever for increasing your qualifying mortgage amount. Two people each earning $75,000 qualify on $150,000 in combined gross income — nearly doubling the maximum mortgage a single $75,000 earner could qualify for on their own. Both borrowers' debts are also included in the TDS calculation, so the net effect depends on both parties' full financial profile.
