How much mortgage can I afford Ontario is the question every calculator answers badly, because the answer depends on the stress test rather than on the rate you were quoted. Lenders qualify you at your contract rate plus two percentage points, or 5.25%, whichever is higher.
At a 4.39% contract rate that means qualifying at 6.39%. The tables below run real Ontario numbers at that qualifying rate, with the minimum down payment and the insurance premium included.
How much mortgage can I afford Ontario: the income required
How much mortgage can I afford Ontario depends on the assumptions, so here they are. These figures assume the minimum down payment, a 25-year amortization, property tax at about 0.95% of the purchase price, $150 a month for heat, and no other debt payments. Lenders cap gross debt service at roughly 39% of gross income.
| Purchase price | Minimum down payment | Insured mortgage | Qualifying payment at 6.39% | Household income needed |
|---|---|---|---|---|
| $600,000 | $35,000 | $587,600 | $3,897 | About $139,000 |
| $700,000 | $45,000 | $681,200 | $4,518 | About $161,000 |
| $850,000 | $60,000 | $821,600 | $5,449 | About $193,000 |
| $925,900 (GTA benchmark) | $67,590 | $892,642 | $5,920 | About $209,000 |
| $1,000,000 | $75,000 | $962,000 | $6,380 | About $225,000 |
The qualifying payment is not the payment you make. At an actual 4.39% rate, the $700,000 example pays about $3,729 a month rather than $4,518. The stress test decides what you are allowed to borrow; the contract rate decides what you pay.
Car loans, credit card minimums, student loans and child support all come out of that same ratio. Roughly speaking, every $400 a month of other debt payments cuts your purchase power by about $60,000.
The 30-year amortization option
How much mortgage can I afford Ontario changes with the amortization. First-time buyers and buyers of newly built homes can get an insured mortgage with a 30-year amortization. It lowers the qualifying payment, which raises what you can borrow.
| Purchase price | Income needed, 25-year amortization | Income needed, 30-year amortization |
|---|---|---|
| $600,000 | About $139,000 | About $131,000 |
| $700,000 | About $161,000 | About $151,000 |
| $850,000 | About $193,000 | About $182,000 |
| $1,000,000 | About $225,000 | About $212,000 |
The trade-off is total interest. Thirty years of payments on the $700,000 example costs tens of thousands more than twenty-five, so use the longer amortization to qualify and then prepay if your income allows.
Down payment rules that change the answer
The minimum is 5% on the first $500,000 and 10% on the portion between $500,000 and $1.5 million. Above $1.5 million you need 20% and the mortgage cannot be insured, which is why the jump at that price point is so large.
Mortgage default insurance is added to the loan, not paid in cash. It costs 4.00% of the mortgage with less than 10% down, 3.10% between 10% and 14.99%, and 2.80% between 15% and 19.99%.
On the $700,000 example, the premium adds about $31,000 to the balance. Twenty percent down removes it entirely, which is worth running as a second scenario if the cash is within reach.
Closing costs in Ontario
Closing costs sit outside the how much mortgage can I afford Ontario calculation but not outside your bank account. Land transfer tax is the big one. In Toronto you pay it twice, provincially and municipally. First-time buyers can claim a provincial refund of up to $4,000 and a Toronto refund of up to $4,475, so confirm the current amounts before budgeting.
| Cost | Typical range on a $700,000 purchase |
|---|---|
| Ontario land transfer tax | About $10,000 before any first-time buyer refund |
| Toronto municipal land transfer tax | A similar amount again, Toronto only |
| Legal fees and disbursements | $1,500 to $2,500 |
| Home inspection | $400 to $700 |
| Title insurance | $300 to $600 |
| Adjustments and moving | $1,000 to $3,000 |
Lenders also want to see 1.5% of the purchase price available for closing costs, separate from the down payment. Buyers outside Toronto pay one land transfer tax instead of two, which is part of why Brampton and Mississauga budgets stretch further.
How much mortgage can I afford Ontario against actual prices
The GTA benchmark price was $925,900 in August 2026, down 4.5% from a year earlier, and the average was $993,410. Condo apartments averaged $617,593 and townhouses $786,817.
So a household earning $139,000 can buy a $600,000 condo or town comfortably in much of the GTA, while a detached home at a $1,288,669 average needs income well above $250,000 or a much larger down payment.
Current prices are published by CREA, and the bond yields that set fixed rates are on the Bank of Canada site.
Two views on borrowing to your maximum
The case for buying at the top of your range
Prices are below last year and inventory is higher,, so your money buys more house than it did in 2025. Stretching once, early, can mean not moving again in five years, and moving costs $40,000 or more in taxes and fees each time.
The case for buying below your maximum
The stress test is not a safety margin, it is a qualification rule. A household approved at 39% gross debt service is committing roughly half of its take-home pay to housing once utilities and maintenance are counted.
Renewal risk is the other half of it. Borrowers who signed at 2% and renewed this year saw payments rise 15% on average, and buying at your ceiling leaves nothing to absorb that in 2031.
Five steps before you shop
- Get a real pre-approval, not an online estimate. It comes with a rate hold of 90 to 120 days and a number a lender will stand behind.
- Pay down the small debts first. Clearing a $400 car payment does more for your purchase power than saving another $10,000.
- Separate your down payment from your closing costs. Lenders check for both, and land transfer tax is due on closing day.
- Get gift letters early. Down payment help from family needs documentation and a 90-day history in your account.
- Run the payment at renewal. If your budget only works at today’s rate, the answer to how much mortgage can I afford Ontario is a smaller number than the lender will approve.
Key takeaways
- The how much mortgage can I afford Ontario answer starts with the stress test: lenders qualify you at your rate plus two points, or 5.25%, whichever is higher.
- A $700,000 purchase with the minimum down payment needs roughly $161,000 of household income.
- A 30-year insured amortization is available to first-time buyers and new-build buyers.
- Minimum down payment is 5% to $500,000, then 10% to $1.5 million, then 20%.
- Answering how much mortgage can I afford Ontario properly means budgeting closing costs and the renewal payment too.
How much mortgage can I afford Ontario on one income
Single-income households asking how much mortgage can I afford Ontario run into the ratio before they run out of down payment. One salary of $110,000 with no other debt supports roughly $470,000 of purchase price at a 6.39% qualifying rate.
Two fixes move that number. A larger down payment reduces the loan and removes the insurance premium at 20%, and a co-signer adds income without adding to the purchase price.
A co-signer is not free of consequences. The mortgage appears on their credit and affects their own borrowing, so it works best with a written agreement about who pays what.
Rental income can also count. Most lenders add 50% to 80% of documented rent from a basement unit, which is why legal secondary suites in Brampton and Mississauga change the math for buyers stretching to a detached home.
What lenders check besides income
How much mortgage can I afford Ontario also depends on your file, not only your income. Credit score sets your rate tier. Below 680 the options narrow and pricing rises; below 600 you are generally looking at alternative lenders at materially higher rates.
Income stability matters as much as the amount. Salaried employees past probation are simplest. Self-employed applicants usually need two years of T1 generals and notices of assessment, and commission income is averaged over two years.
Down payment source is verified with 90 days of statements. Gifts need a letter; cryptocurrency and cash deposits attract questions, so move funds into a regular account early.
The answer to how much mortgage can I afford Ontario therefore has two parts: what the ratios allow, and what the lender will document. A pre-approval tests both.
Frequently asked questions
Does the stress test apply if I have 20% down?
Yes. The how much mortgage can I afford Ontario answer uses the stress test for insured and uninsured mortgages alike at federally regulated lenders. The exception is an uninsured straight switch at renewal, where the same balance and amortization move to a new lender.
Do both incomes count?
Yes, for a joint application, along with both sets of debts. Lenders use the lower credit profile of the two for rate qualification at many institutions.
Can I use the same numbers in Brampton and Toronto?
The mortgage math is the same. Property tax rates and land transfer tax differ, and Toronto’s second land transfer tax adds thousands to closing.
