Income Needed to Buy a Home in Ontario
Mortgage affordability in Ontario depends on more than just a home’s purchase price and your household income. Lenders approve mortgages based on qualifying income, mortgage amount, downpayment, and debt service ratios, not simply the advertised mortgage rate. That means two homebuyers in the same Ontario city can face different approval limits depending on the mortgage amount and structure.
We’ll explain how mortgage qualification works in Ontario and show how income requirements vary across the province. Home prices are updated monthly using the latest market data from OREA and CREA, and all qualifying figures reflect nesto’s current rates, lending standards, and federal stress test rules.
Key Takeaways
- Mortgage approval in Ontario is based on qualifying income calculated at stress tested interest rates, not contract mortgage rates.
- The income required for the same mortgage amount can vary across Ontario municipalities due to property taxes and home values.
- Downpayment size and mortgage insurability can materially change approval outcomes for the same loan amount.

Qualifying for a Mortgage in Ontario
Insured, insurable, and uninsured mortgages differ in down payment, property value, amortization, and rate. Insured mortgages require less than 20% down and a borrower-paid premium from CMHC, Sagen, or Canada Guaranty. Insurable needs 20% or more on a property under $1 million with a 25-year amortization, and the lender pays the premium, which is why it prices close to insured. Uninsured covers everything else, including any refinance, and is the most expensive because the lender carries the full risk. Debt service limits are the same across all three: 39% GDS and 44% TDS. What differs is the minimum credit score, the amortization, and the rate.
Details
*30-year amortizations on insured purchases are limited to first-time homebuyers and buyers of newly built homes.
**The minimum qualifying rate applies to purchases and refinances, not to a renewal with your current lender or a straight switch where your balance and remaining amortization do not increase. Your contract rate plus 2% is the binding figure for almost every borrower today; the 5.25% floor only takes over if rates fall below 3.25%.
***nesto’s minimum credit score is 680 on uninsured mortgages and 600 on insured and insurable mortgages. Debt service ratios of 39% and 44% apply to all three insurability options, so a larger down payment no longer means tighter ratios. All criteria apply to an owner-occupied primary residence mortgage with nesto.
****Loan-to-income applies to uninsured mortgages only, effective 1 January 2025. A file above 4.5 times income is reviewed for an exception rather than declined.
How much can you borrow against your income?
On uninsured mortgages, nesto also checks your loan-to-income (LTI) ratio: everything borrowed against the property compared to your annual household income. If it’s above 4.5 times income, the file goes to an underwriter for an exception rather than being declined. It counts first and second mortgages, a home equity line of credit, and any other borrowing registered against the title, whether the lender is nesto or another institution, and whether you live there or rent it out.
A household earning $150,000 reaches the threshold at about $675,000 of total borrowing. A $100,000 line of credit behind a $600,000 mortgage puts them at 4.7, even though the mortgage alone would have cleared it. LTI applies only to uninsured mortgages, effective 1 January 2025, and reflects OSFI’s loan-to-income limits, which cap high-LTI lending across a lender’s entire book rather than setting a hard ceiling per borrower.
New purchase qualifying rates
Your qualifying rate is our lowest fixed or variable rate for your insurance type, plus 2%:
- Insured: 6.59% fixed or 5.45% variable
- Insurable: 6.59% fixed or 5.46% variable
- Uninsured: 7.09% fixed or 5.84% variable, plus the 4.5 times loan-to-income check
If rates fall below 3.25%, the OSFI floor of 5.25% becomes binding instead.
Renewal (switch or transfer) qualifying rates
A straight switch is exempt from the stress test, so you may renew at the contract rate on our lowest fixed or variable rate for your insurance type:
- Insured: 4.59% fixed or 3.45% variable
- Insurable: 4.59% fixed or 3.46% variable
- Uninsured: 5.09% fixed or 3.84% variable
Asking to increase your mortgage balance or to extend the amortization makes the transaction a refinance.
How Mortgage Qualification Works in Ontario
All new mortgage purchases and refinances in Ontario must pass the federal mortgage stress test. Borrowers are qualified at the minimum qualifying rate, which is the higher of 5.25% (benchmark rate) or their contract rate plus 2%, regardless of whether they choose a fixed or variable mortgage. The qualifying rate is used solely for qualifying mortgage approvals and does not reflect the actual interest rate used to calculate monthly payments.
Lenders then apply gross debt service (GDS) and total debt service (TDS) ratios to determine whether a borrower’s income can support their housing costs and other debts. These debt service ratios differ depending on whether the mortgage is insured, insurable, or uninsured.
| Transaction Type & Limitation | Minimum GDS | Minimum TDS |
|---|---|---|
| Credit score (FICO) for the lowest-score borrower (between 650 and 680) | 32 | 40 |
| Uninsured refinance or uninsured purchase of a property valued at $1.5 million or more | 35 | 42 |
| Insured purchase with a down payment of less than 20% (also applies to insurable mortgages for new purchases and renewals) | 39 | 44 |
Insured, Insurable, and Uninsured Mortgages in Ontario
Mortgage structure, particularly the loan-to-value (LTV) ratio based on the downpayment, plays a significant role in affordability.
Insured mortgages apply when the downpayment is under 20% and generally allow higher qualifying ratios. Insurable mortgages available for new purchases and renewals meet insurer standards with a 20% downpayment on amortizations up to 25 years, and are limited to properties under $1M. Uninsured mortgages avoid mortgage insurance premiums but are subject to tighter debt service limits, allowing 30-year amortizations and financing for homes valued at $1.5 million or more.
Understanding which default mortgage insurance category applies to your purchase in Ontario can significantly affect the income you need to qualify.
In Ontario, mortgage default insurance premiums are subject to the provincial sales tax (PST), which must be paid upfront and cannot be added to the mortgage balance, affecting the total required for closing costs.
Mortgage Default Insurance Requirements
Mortgage default insurance is mandatory for downpayments under 20%, impacting your mortgage qualifying amount and monthly costs. Default insurance often applies to higher-LTV loans, making high-ratio mortgages more affordable. Due to limitations on amortization periods, these mortgages require a smaller downpayment despite having a higher monthly payment.
| Loan-to-Value | Premium (25-year Amortization) | Premium (30-year amortization) |
|---|---|---|
| 80.01% to 85% | 2.80% | 3.00% |
| 85.01% to 90% | 3.10% | 3.30% |
| 90.01% to 95% | 4.00% | 4.20% |

Income Needed Across Ontario Cities
Mortgage qualification rules are consistent across Ontario, but home prices and property tax rates vary by municipality. These differences affect income requirements across the province even when the mortgage amount is similar.

|---|---|---|
| Minimum Downpayment | $49,980 | $699,820 |

Frequently Asked Questions (FAQ) on Mortgage Affordability in Ontario
How much income do I need to buy a house in Ontario?
The income needed to buy a home in Ontario depends on the mortgage amount, downpayment, property taxes, and the mortgage stress test. For an average-priced home in Ontario, qualifying income currently ranges from $140,641 to $169,927, depending on the mortgage structure.
How does the mortgage stress test work in Ontario?
Borrowers must qualify at the minimum qualifying rate (MQR), which is the higher of 5.25% (federal benchmark rate) or their contract rate plus 2%. This qualifying rate is used solely for mortgage approval and does not affect the actual monthly payment.
How much house can I afford on a $100k salary in Ontario?
Affordability depends on other debts, downpayment size, and local home prices. In lower-priced Ontario cities, a $100k household income may support a larger purchase than in higher-priced markets such as Toronto, but approval is always based on stress-tested ratios.
For example, the income requirement to qualify for a $100,000 mortgage balance typically ranges from $23,873 to $30,257. You can use this as a factor to assess how much you’ll qualify for a $100,000 income.
How much income do I need for a $500k mortgage in Ontario?
Under current stress test rules, the qualifying income required for a $500k mortgage in Ontario ranges from $107,059 to $137,572, depending on mortgage type and amortization. Typically, you’ll need slightly more income to qualify for a $500K mortgage in Ontario, as the above figures are based on Canada’s 1% average property tax rates, while Ontario has a slightly higher average property tax rate of 1.26%.
How much mortgage can I afford with a 20% down payment in Ontario?
A 20% downpayment reduces the mortgage amount and avoids mortgage insurance premiums. However, uninsured mortgages are subject to tighter debt service limits, which can reduce the maximum mortgage approval amount compared with insured or insurable mortgages.
Typically, you’ll qualify for a mortgage amount of 4 to 5 times your household income. Based on Ontario’s average home price of $749,800 currently, a 20% downpayment would set you back $149,960. You’ll need to qualify for a mortgage balance of $599,840 if you’d like to buy the average-priced home in the province.
Final Thoughts
Mortgage affordability in Ontario depends on how income, mortgage balance, downpayment structure, and property tax rates interact under the federal stress test rules. Looking only at home prices or mortgage rates does not provide a complete picture of what lenders will approve.
Understanding how these variables interact enables borrowers to make more suitable decisions. Adjusting the downpayment amount, selecting a suitable amortization period, or structuring the mortgage correctly can meaningfully change qualifying income and long-term affordability.
