What lenders look at when approving a mortgage in Ontario
Lenders review more than just income when approving a mortgage. Understanding these factors early helps you set a realistic budget.
- Income and employment stability
- Credit score and repayment history
- Debt-to-income ratios including car loans and credit cards
- Down payment source such as savings, FHSA, RRSP Home Buyers’ Plan, or gifted funds
- Property-related costs including taxes, heating, and condo fees
Mortgage pre-approval Ontario buyers should get first
A mortgage pre-approval Ontario buyers rely on confirms a price range and provides a temporary rate hold. It shows sellers that your financing has been reviewed, but it is not a final approval.
What pre-approval does and does not do
- It does: set expectations for price and payments
- It does not: guarantee financing without a property review
Down payment rules in Ontario
Your down payment affects approval, insurance requirements, and affordability.
- 5% on the first $500,000 of the purchase price
- 10% on the portion between $500,000 and $999,999
- 20% for homes priced at $1 million or more
These minimum down payment requirements are set federally and apply across Canada.
Buyers using less than 20% down typically require mortgage default insurance, which is added to the mortgage amount.
Mortgage default insurance rules are administered by CMHC and other approved insurers .
Understanding the mortgage stress test
Federally regulated lenders apply a mortgage stress test. Buyers must qualify at the higher of the contract rate plus 2 percent or the minimum qualifying rate.
In practical terms, this means you must afford your mortgage at a higher rate than what you will actually pay. This reduces borrowing power but protects buyers if rates rise.
See the official minimum qualifying rate from OSFI .
Fixed vs variable mortgage rates
Choosing between fixed and variable rates is a core part of mortgage financing for Ontario home buyers.
Fixed-rate mortgages
- Predictable payments
- Budget stability
- Often higher penalties to break early
Variable-rate mortgages
- Payments or amortization can change as rates move
- May cost less over time but carry more risk
- Often more flexible to break
A lender vs alternative lender: what Ontario buyers should know
Most first-time buyers aim to qualify with an A lender, which typically offers lower rates and standard terms. Alternative lenders may be an option for buyers with variable income or credit challenges but often involve higher costs.
Monthly affordability: more than just the mortgage payment
- Mortgage payment
- Property taxes
- Condo fees
- Utilities and insurance
- Maintenance and repairs
Example: how pre-approval translates to real buying power
A buyer approved for $700,000 may choose to shop closer to $625,000 after accounting for condo fees, taxes, and long-term comfort. This is common for first-time buyers in the GTA.
How mortgage financing affects your offer strategy
- Stronger pre-approval supports cleaner offers
- Financing conditions affect competitiveness
- Condo purchases require timing for status review
Financing limits often influence whether buyers stay in the GTA or widen their search to nearby regions.
Common mortgage financing mistakes
- Shopping before pre-approval
- Maxing out lender-approved budgets
- Ignoring condo fees
- Not documenting gifted funds early
