Ontario residential purchase financing
A purchase mortgage is a plan, not just a payment.
The best time to understand your financing is before the offer. A clear purchase plan connects your income, credit, down payment, property type and closing timeline to lenders that are realistically suited to the file.
The purchase-financing sequence
Start with the facts that lenders will test.
Purchase financing starts with more than a purchase price. A useful review considers how income is earned, recurring debt, credit history, cash available for the down payment and closing costs, the target property and the date on which you need to close. Those pieces determine both the range to explore and the documents needed to support it.
For Ontario buyers, the practical order is straightforward: set a household budget, establish the down-payment source, complete a meaningful qualification review, shop within a range that leaves room for closing, then move quickly on a property with a financing condition where appropriate. Once an offer is accepted, the lender still reviews the property and the final documents.
A lender decision is never created by a calculator alone. Use the affordability calculator as an illustrative starting point, then use a detailed qualification review to test the assumptions against actual lender policy.
Lender paths
Prime, alternative and credit-union options solve different problems.
The right category follows the file; it is not a badge of success or failure.
Prime lending
Prime lenders generally look for established, well-documented income, satisfactory credit, manageable debt ratios and a property that fits policy. Salaried and hourly employees with conventional documentation often begin here, but the outcome is always lender-specific.
Alternative lending
Alternative or B-lending can be a practical fit when tax returns understate a self-employed household’s capacity, credit needs time to recover, or income does not fit a conventional template. Terms, fees and an eventual move back to prime financing should be considered before choosing this route.
Credit unions and specialized programs
Provincially regulated credit unions and other lenders can have their own policies, qualifying approaches and property preferences. Certain insured and conventional lending programs can have different qualification rules; available options are reviewed based on the actual scenario.
How qualification is measured
Stress test
At many federally regulated lenders, borrowers are qualified at the higher of the contract rate plus 2% or the lender’s qualifying rate. This can reduce the mortgage amount that a household qualifies for compared with the payment calculated at the contract rate. It is one reason an online payment can look affordable while the qualifying range is lower.
GDS and TDS
Gross debt service (GDS) compares housing costs with gross income. Total debt service (TDS) adds other recurring obligations such as vehicle loans, credit-card minimum payments, lines of credit and support payments. Lenders set their own limits and can treat income, condo fees, rental income and debts differently, so the ratios are guides rather than universal promises.
Comfort matters too
Qualification uses lender rules; affordability uses your household life. Before setting an offer ceiling, include property tax, condo fees, utilities, maintenance, commuting, childcare, insurance and an emergency reserve. A mortgage that fits a ratio may still not suit your preferred cash flow.
Down payment and default insurance
For purchases below $500,000, the federal minimum down payment is generally 5%. From $500,000 to $1.5 million, the minimum is generally 5% of the first $500,000 and 10% of the portion above it. A purchase of $1.5 million or more generally requires at least 20% down. Review the detail in the Ontario down-payment guide.
When the down payment is below 20%, mortgage default insurance is normally required, subject to insurer and lender rules. The premium is typically based on the loan-to-value ratio and can often be added to the mortgage; provincial sales tax on the premium is usually payable at closing. Default insurance protects the lender, not the buyer, and does not remove the need to qualify.
Whatever the amount, the lender will normally need evidence of the source. Savings, investments, proceeds from sale, gifts and registered-plan withdrawals each have different documentation expectations.
Three different stages
Pre-qualification, pre-approval and approval are not interchangeable.
Knowing the stage protects your expectations and helps you communicate accurately with your Realtor.
Pre-qualification
A planning assessment based on the information and documents currently available. It helps identify a range, likely lender path, documents and open questions. It is not a lender commitment.
Pre-approval
A lender process that may include a credit review and some document verification. It can still be conditional and may not include final property approval, appraisal or all underwriting requirements.
Mortgage approval
A lender’s decision after reviewing the completed application, supporting documents and the accepted property. Conditions may remain until each item is satisfied and the lender’s closing instructions are issued.
Prepare before the offer
Documents that make a file easier to review.
- Recent employment and income confirmation, such as pay stubs, employment letter, T4s, Notices of Assessment or T1 Generals as applicable.
- A clear record of the down-payment source, commonly including recent statements and a gift letter where funds are gifted.
- Details of recurring debts, property taxes and condo fees where known, plus any existing mortgage or property-sale information.
- For self-employed and variable-income households, business records, bank statements, contracts or financial statements that explain how income is earned.
- A careful review of the purchase agreement, condominium status certificate where relevant, and property-specific conditions once an offer is accepted.
Do not send government ID, credit-report authorizations, account passwords or banking-login details through an initial website inquiry. If document collection is needed, follow the brokerage’s secure process and redact information that is not required.
A typical closing timeline
Move from planning to possession without leaving the basics late.
- 01
Before shopping
Build the budget, determine the down-payment source and obtain a meaningful review.
- 02
Offer period
Confirm the financing condition, deposit timing, property details and the documents needed by the lender.
- 03
Conditional approval
Supply the lender’s requested documents promptly; the lender assesses the borrower and property.
- 04
Before closing
Your lawyer receives lender instructions, confirms closing funds and handles title, tax, adjustments and registration.
- 05
After closing
Set up payment, insurance and utility arrangements; retain your mortgage and closing records.
Protect the plan
Common failure points are often visible early.
Changing the file after pre-qualification
Avoid new credit, large purchases, employment changes or unexplained transfers before closing unless you first understand the effect on the file.
Treating the down payment as a single number
Lenders need to understand where the money came from. The amount, source, timing and paper trail each matter.
Ignoring property conditions
A lender can assess the property as well as the borrower. Appraisal value, condo status, zoning, condition and marketability can all matter.
Using a maximum as a target budget
A qualifying ceiling is not automatically a comfortable household budget. Taxes, condo fees, utilities, maintenance, childcare and life changes still belong in the decision.
Questions
Purchase mortgage FAQs
Is a pre-qualification the same as a pre-approval?
No. A pre-qualification is a planning review based on the information available. A lender pre-approval is a lender process that may include credit and document review, but it still has conditions. A full mortgage approval comes after the lender underwrites the borrower and the specific property.
What does the mortgage stress test do?
For many federally regulated lenders, qualification is tested at the higher of the contract rate plus 2% or the lender’s qualifying rate. The purpose is to test whether the household can carry payments if rates are higher at renewal. The exact treatment depends on the lender and program.
Can I buy with less than 20% down?
Often, yes. A purchase below $1.5 million can generally use an insured mortgage when the minimum down payment rules and insurer requirements are met. Mortgage default insurance is normally required below 20% down and its premium is commonly added to the mortgage.
How much should I reserve for closing costs?
Closing costs are separate from the down payment. Plan for land transfer tax, legal fees and disbursements, title insurance, inspection costs, appraisal where required, adjustments, moving and a reserve. Your lawyer should confirm the actual closing statement.
Do alternative lenders only help buyers with poor credit?
No. Alternative lending can be relevant where income is hard to document conventionally, a borrower has recently changed careers, or a file falls outside a prime lender’s policy. It can involve different rates, fees, terms and exit planning, so suitability matters.
When should I start a qualification review?
Start before making an offer, ideally while you are setting a budget. A real review can identify documentation gaps, down-payment questions and lender fit before timing becomes urgent.
What can cause a purchase file to fail late?
Common issues include a changed job or income, new debt, an undocumented deposit, an appraisal below the purchase price, a property that does not meet lender policy, or documents that do not support the application. Preparation cannot remove every condition, but it reduces avoidable surprises.
