Mortgage Affordability Calculator Ontario 2026
Estimate an Ontario home-buying range from income, debt, down payment and monthly ownership costs, then compare it with Canada's mortgage qualification framework.
How much home can you afford in Ontario?
Start with household income, but do not stop there. Canadian mortgage qualification also considers housing costs and other debts. Federal consumer guidance says total monthly housing costs generally should not exceed 39% of gross household income (GDS), while total debt load generally should not exceed 44% (TDS).
Test your budget against GDS/TDS, the federal mortgage stress test, your minimum down payment, Ontario land transfer tax, closing costs and a realistic monthly cash-flow buffer.

Mortgage stress test in Ontario
Ontario borrowers using federally regulated lenders are generally subject to Canada's mortgage qualifying framework. OSFI currently sets the minimum qualifying rate for uninsured mortgages at the greater of 5.25% or the mortgage contract rate plus 2 percentage points.
4.5% contract rate
4.5% + 2% = 6.5%, so 6.5% is the qualifying rate because it is above the 5.25% floor.
3.0% contract rate
3.0% + 2% = 5.0%, so the 5.25% floor is higher.
The calculator above is a planning tool and does not replace a lender's full stress-test calculation or underwriting.
Ontario GDS and TDS ratios
| Ratio | General guideline | What it considers |
|---|---|---|
| GDS | 39% | Mortgage payment, property taxes, heating and 50% of condo fees where applicable |
| TDS | 44% | Housing costs plus other debts such as car loans, credit cards and lines of credit |
A household can have a strong income and still lose mortgage capacity when monthly debt payments are high. Reducing consumer debt before applying can therefore change the amount of housing payment that fits inside TDS.
Minimum down payment in Ontario
| Purchase price | Federal minimum down payment |
|---|---|
| $500,000 or less | 5% of purchase price |
| Over $500,000 and under $1.5M | 5% of first $500K + 10% of the portion above $500K |
| $1.5M or more | 20% |
With less than 20% down, mortgage loan insurance is typically required, subject to eligibility and lender rules. Use the Down Payment Calculator to turn a target home price into a cash goal.
Ontario land transfer tax can change the cash you need
Ontario land transfer tax is progressive. Current provincial rates are 0.5% on the first $55,000, 1% from $55,000 to $250,000, 1.5% from $250,000 to $400,000, 2% above $400,000, and 2.5% on the portion above $2 million where the property contains one or two single-family residences.
That tax is separate from the mortgage itself, so it belongs in your cash-to-close plan. Buyers in Toronto should also check the city's municipal land transfer tax. Legal fees, title insurance, adjustments and other closing expenses can add more.
Ontario affordability examples
Rather than treating salary as a direct home-price multiple, test the same income under different debt and interest-rate scenarios. A $100,000 household with no consumer debt can have a very different mortgage range from a $100,000 household carrying a large car loan and revolving credit balance. Property taxes and condo fees can also materially change GDS.
