Mortgage qualification in Canada is the process that lenders follow to determine how much mortgage a borrower can afford. This comes down to assessing the risk involved with the borrower’s ability to repay the loan based on income, existing debts, credit history, and the property itself.
Mortgage qualification factors
One of the first qualification factors that lenders assess is income and employment stability. When it comes to income, lenders look at factors such as salary, commissions, overtime, investment income, and employment status like self-employed versus employee. They typically require proof of income, which includes T4s, pay stubs, and Notices of Assessment (NOAs), as well as financial statements for self-employed individuals.
Income verification by employment type
The documentation you need depends on how you earn your income:
| Employment Type | Documents Required | How Income Is Calculated |
|---|---|---|
| Salaried (full-time) | Recent pay stub, T4, letter of employment | Base salary used; bonus/overtime may be averaged over 2 years |
| Hourly (full-time) | Recent pay stubs, T4, letter of employment | Averaged over most recent 2-year period |
| Commission-based | 2 years of T4s, NOAs, letter of employment | 2-year average of commission income |
| Self-employed | 2 years of T1 Generals, NOAs, financial statements | 2-year average of net business income (after expenses) |
| Part-time / Contract | 2 years of T4s, NOAs, employment history | 2-year average; must show consistent history |
| Rental income | Lease agreements, T1 Generals | Typically 50%–80% of gross rental income is used |
Self-employed borrowers face additional scrutiny. Lenders may use the income reported on your tax return rather than your gross business revenue, which can significantly reduce your qualifying amount. Some lenders offer stated income programs for self-employed Canadians with strong credit and a significant down payment.
Credit score requirements
Your credit score is one of the most important factors in mortgage qualification. Canadian credit scores range from 300 to 900, and different tiers affect what mortgage products and rates are available to you.
Credit score tiers and their impact
| Credit Score Range | Rating | Impact on Mortgage |
|---|---|---|
| 760+ | Excellent | Best rates available; easiest approval; most lender options |
| 725 – 759 | Very Good | Competitive rates; broad lender access |
| 680 – 724 | Good | Meets minimum for most A-lenders; standard rates |
| 620 – 679 | Fair | May require B-lender; higher rates; larger down payment may help |
| 580 – 619 | Below Average | Limited to B-lenders and private lenders; significantly higher rates |
| Below 580 | Poor | Private lenders only; highest rates; may need co-signer |
Most major Canadian banks and A-lenders require a minimum credit score of 680 for conventional mortgage approval. A score of 760 or above typically qualifies you for the best available rates. If your score is between 620 and 679, you may still qualify through B-lenders or alternative lenders, though the interest rate will be higher.
Factors that affect your credit score
- Payment history (35%) — Making all payments on time is the single biggest factor
- Credit utilization (30%) — Keep credit card balances below 30% of your limit
- Length of credit history (15%) — Longer is better
- Credit mix (10%) — Having different types of credit (credit card, car loan, line of credit) is positive
- New credit inquiries (10%) — Multiple hard inquiries in a short period can lower your score
Debt service ratios
The two main debt service ratios that lenders use to assess your mortgage qualification are the Gross Debt Service (GDS) ratio and the Total Debt Service (TDS) ratio. If you want to see how your income and debt impact these key ratios, you can use this debt service ratio calculator.
- GDS ratio — Must be 39% or less. This measures your housing costs (mortgage payment, property taxes, heating, and 50% of condo fees) as a percentage of your gross income.
- TDS ratio — Must be 44% or less. This includes all housing costs plus other monthly debt obligations (car loans, credit cards, student loans, lines of credit).
Some lenders may allow slightly higher ratios for borrowers with excellent credit scores and strong financial profiles.
Mortgage stress test
If you are acquiring a mortgage from a federally regulated lender, you will need to pass the mortgage stress test. This involves testing your mortgage payment against debt service ratios at the higher of 5.25% or the contract mortgage rate plus 2.00%. You can see how the mortgage stress test impacts your home affordability by using a mortgage stress test calculator.
What lenders look at: a complete checklist
Canadian mortgage lenders evaluate several key factors when assessing your application:
- Income and employment — Stable, verifiable income with documentation appropriate to your employment type
- Credit score — Minimum 680 for A-lenders; each tier above that may unlock better rates
- Debt service ratios — GDS ≤ 39% and TDS ≤ 44% using the stress test qualifying rate
- Down payment — Minimum 5% for homes up to $500,000; 10% on the portion between $500,000 and $1,499,999; 20% for homes $1.5 million and above
- Property appraisal — The lender will confirm the property value supports the mortgage amount
- Loan-to-value ratio — Determines whether mortgage insurance is required (LTV above 80%)
Use the debt service ratio calculator to see where you stand, and the loan-to-value calculator to understand your insurance requirements.
Documents you need for a mortgage application
Preparing the right documentation in advance can speed up your approval process. Here is a step-by-step list of what most lenders require:
Step 1: Identification
- Valid government-issued photo ID (driver’s licence, passport)
- Social Insurance Number (SIN)
Step 2: Proof of income
- Most recent pay stubs (last 30 days)
- T4 slips (last 2 years)
- Notice of Assessment (NOA) from the CRA (last 2 years)
- Letter of employment confirming position, salary, and start date
- For self-employed: T1 General tax returns, financial statements, business licence
Step 3: Proof of down payment
- Bank statements showing the source of your down payment (last 90 days)
- Gift letter (if part of the down payment is a gift from a family member)
- RRSP Home Buyers’ Plan withdrawal statement (if applicable)
- FHSA withdrawal documentation (if applicable)
Step 4: Debt and credit information
- Credit card statements with current balances
- Loan statements (car loans, student loans, personal loans)
- Child support or alimony obligations (if applicable)
Step 5: Property information
- Signed Agreement of Purchase and Sale
- MLS listing for the property
- Property tax bill or estimate
- Condo status certificate (if purchasing a condominium)
Common reasons for mortgage rejection
Understanding why mortgage applications are declined can help you prepare and avoid potential issues:
| Reason for Rejection | How to Fix It |
|---|---|
| Credit score too low | Pay bills on time, reduce credit utilization, correct errors on credit report |
| Debt ratios too high | Pay down existing debts, especially high-interest credit cards and car loans |
| Insufficient income | Add a co-borrower, wait for a raise, or look at a lower-priced property |
| Employment instability | Wait until you have at least 3–6 months at a new job; avoid switching jobs during the process |
| Inadequate down payment | Save longer, access RRSP Home Buyers’ Plan or FHSA, or accept a gift from family |
| Property issues | Choose a different property; some property types are harder to finance (e.g., rural, non-standard construction) |
| Unverifiable income | Keep thorough records; consider lenders with stated income programs for self-employed borrowers |
How to qualify for a larger mortgage
If you want to increase your mortgage qualification amount, start by reducing existing debts to improve your TDS ratio. Paying off credit card balances, car loans, or student loans frees up room in your debt ratios. Increasing your income through a raise, side income, or adding a co-borrower can also boost your borrowing power. A larger down payment improves your loan-to-value ratio and may reduce insurance costs. You should also check that your credit report is accurate and address any issues before applying. Run different scenarios through the mortgage stress test calculator and mortgage affordability calculator to understand how these changes impact your qualification.
