MORTGAGE AFFORDABILITY / ONTARIO
How Much Mortgage Can I Afford in Ontario?
A 2026 Homebuyer’s Guide
One of the first questions most Ontario homebuyers ask is: “How much mortgage can I actually afford?”
It may be tempting to look at your salary and use a simple online calculator, but mortgage affordability is based on much more than income alone. Your income, existing debts, down payment, credit profile, property taxes, condo fees, mortgage rate and even the type of property you are purchasing can all affect how much you may qualify for.
Your Income Is Only the Starting Point
Lenders look at your gross income before taxes when assessing your mortgage application. Depending on your situation, eligible income may include employment income, overtime or bonuses, commission income, self-employed income, rental income, certain pension or investment income, and income from a second job.
However, not every type of income is treated the same way. Someone with a guaranteed salary may be assessed differently from someone who earns commissions, bonuses, overtime or self-employment income. This is one reason two buyers earning the same amount can qualify for very different mortgage amounts.
Your Debts Matter Too
Lenders also review your monthly financial obligations. These may include car loans or leases, credit card balances, lines of credit, student loans and other debt payments.
Mortgage lenders commonly use two calculations called Gross Debt Service (GDS) and Total Debt Service (TDS) ratios. For CMHC-insured mortgages, the maximum benchmarks are generally 39% GDS and 44% TDS.
- GDS looks at how much of your income would go toward housing expenses.
- TDS looks at housing expenses plus your other debts.
Reducing a car loan, credit card balance or line of credit before buying a home can sometimes improve your mortgage qualification.
Don't Forget the Mortgage Stress Test
Another important part of mortgage qualification in Ontario is the mortgage stress test. For uninsured mortgages at federally regulated lenders, borrowers are generally qualified using the greater of your mortgage contract rate + 2% or 5.25%.
For example, if your actual mortgage rate were 4.50%, you may need to demonstrate that you can afford the mortgage using a qualifying rate of 6.50%. This does not mean you actually pay 6.50%; it is a qualification test designed to ensure you have some financial room if circumstances or rates change.
How Much Down Payment Do You Need in Ontario?
Your available down payment can significantly affect the home price you can afford. Under current Canadian rules, the minimum down payment is generally:
- Homes up to $500,000: 5% of the purchase price.
- Homes above $500,000 but below $1.5 million: 5% of the first $500,000 plus 10% of the portion above $500,000.
- Homes priced at $1.5 million or more: a minimum 20% down payment is required.
If your down payment is below 20%, mortgage default insurance will typically be required. Remember that your down payment is not the only cash you will need. You should also budget for closing costs such as legal fees, land transfer tax, adjustments and other purchase-related expenses.
Property Taxes and Condo Fees Affect Affordability
A common mistake is assuming mortgage qualification is based only on the mortgage payment. Lenders also consider property taxes, heating costs and, where applicable, condominium fees.
For CMHC debt-service calculations, 50% of applicable condo fees are included when calculating GDS and TDS ratios. This means you may qualify differently for a $650,000 detached home and a $650,000 condo with significant maintenance fees, even though the purchase price is identical.
Can First-Time Homebuyers Get a 30-Year Mortgage?
Potentially, yes. For insured mortgages with less than 20% down, current federal rules allow a maximum 30-year amortization for first-time homebuyers and/or buyers purchasing a new build. Other insured purchases generally remain subject to a 25-year maximum amortization.
A longer amortization can reduce your monthly mortgage payment and may improve affordability, although it generally means paying more interest over the life of the mortgage.
So, How Much Mortgage Can You Afford?
There is not one accurate income-to-mortgage multiplier that works for everyone. Consider two Ontario buyers earning the same household income of $120,000:
| Buyer A | Buyer B |
|---|---|
| No car loan | A $700 monthly vehicle payment |
| Very little credit card debt | Outstanding credit card balances |
| A larger down payment | A smaller down payment |
| Strong credit | Higher monthly obligations |
Even though their incomes are identical, their mortgage qualification could be very different. Statements such as “you can afford four or five times your salary” should only be treated as rough estimates, not mortgage approvals.
Example: $600,000 Ontario Home
| 5% of first $500,000 | $25,000 |
|---|---|
| 10% of remaining $100,000 | $10,000 |
| Minimum down payment | $35,000 |
| Purchase price | $600,000 |
Qualification vs. Comfortable Affordability
There is another important distinction: how much mortgage you can qualify for and how much mortgage you are comfortable carrying are not always the same number.
Your personal budget may include expenses lenders do not fully see in their calculations, such as childcare, private-school fees, travel, family support, lifestyle expenses or savings goals. Getting approved for the maximum possible mortgage does not necessarily mean you should borrow the maximum.
A good mortgage strategy should consider both qualification and long-term affordability.
Before You Start Shopping for a Home
Instead of choosing a home price first and trying to arrange financing afterward, consider completing a mortgage affordability review before seriously shopping.
- How much mortgage you may qualify for
- Your estimated maximum purchase price
- The down payment you will require
- Approximate monthly mortgage payments
- How existing debts affect your qualification
- Which mortgage options may fit your circumstances
- Whether there are steps you can take to strengthen your application
That can give you a much clearer price range before you begin making offers.
Want to Know Your Mortgage Affordability?
Every mortgage application is different. Your income may come from two jobs. You may be self-employed. You may have commission or bonus income. You may already own a property. Or you may simply want to know what price range makes sense before starting your home search.
