Key Takeaways

• Commission-based income earners can qualify for a mortgage in Canada, but lenders assess income differently than they do for salaried employees.
• Most lenders use a two-year average of commission income to determine qualifying income; some use the lower of the two years.
• If commissions are trending upward, select lenders may use the most recent year or a weighted average.
• T4-employed commission earners qualify more easily than T4A self-employed earners, who face stricter scrutiny.
• Required documents typically include two years of T1 returns, Notices of Assessment (NOA), T4/T4A slips, pay stubs, and an employment letter.
• In 2026, lenders require roughly 40% more documentation than in 2024 for variable-income profiles. [7]
• The mortgage stress test remains at the greater of your contract rate +2% or 5.25%, unchanged for commission earners. [5]
• Minimum credit score requirements have tightened to 680+ for conventional mortgages in 2026. [7]
• A mortgage broker is often the most effective resource for commission earners, as brokers can match borrowers to lenders with flexible income policies.
• Private and alternative lenders are viable backup options when traditional banks decline.

Quick Answer

Commission-based income earners in Canada qualify for mortgages by having lenders average their last two years of commission income to calculate a stable qualifying figure. The key variables are employment type (T4 vs. T4A), income trend, credit score, and documentation quality. With the right preparation and lender match, most commission earners can access competitive mortgage products, including insured and conventional options.

What Are the Mortgage Options for Commission-Based Income Earners in Canada?

Commission-based income earners in Canada have access to the same core mortgage products as salaried borrowers, including insured mortgages (less than 20% down), conventional mortgages (20%+ down), and alternative or private lending products. The difference lies in how lenders calculate qualifying income, not in which products are available.

Main mortgage options available:

For commission earners with a solid two-year income history and good credit, A-lender (bank or monoline) mortgages are the most cost-effective route. Those with shorter histories or income volatility should explore B-lenders or, as a last resort, private mortgage options.

💡 Key point: The mortgage product itself isn’t the challenge. The challenge is proving stable qualifying income to the lender’s satisfaction.

How Do Lenders Calculate Income for Commission Earners?

Lenders use a structured approach to average out the variability in commission pay. The most common method is a two-year average, but the specific calculation depends on your income trend and employment type. [1]

The Three Income Calculation Methods

1. Two-Year Average (most common) Add both years together and divide by two. Example: $85,000 (Year 1) + $95,000 (Year 2) = $90,000 qualifying income [1]

2. Lower of Two Years (conservative lenders) Some lenders use the smaller figure to reduce risk. Example from above: qualifying income = $85,000 [1]

3. Most Recent Year or Weighted Average (upward trend) If income is clearly increasing, select lenders may use the most recent year or weight it more heavily. Example: $75,000 (Year 1) → $95,000 (Year 2) = lender may qualify at $95,000 [1]

T4 vs. T4A: Why It Matters

This is one of the most important distinctions for commission earners:

• T4 (employed commission earner): Your employer withholds taxes and issues a T4. Lenders treat this similarly to salaried income, with employer verification making qualification more straightforward.
• T4A (self-employed commission earner): You receive a T4A and are responsible for your own taxes. Lenders treat this as business income, which often means higher down payment requirements and stricter documentation. [1]

For a deeper look at how self-employed income is treated, see The Ultimate Guide to Securing a Mortgage for Self-Employed Canadians.

Common mistake: Assuming a T4A puts you in the same category as a salaried employee. It doesn’t. If you receive T4A income, prepare for the same level of scrutiny as a self-employed borrower.

What Documents Do Commission Earners Need for a Mortgage Application?

Lenders require specific documentation to verify commission income. As of 2026, documentation requirements have increased significantly, with lenders requesting roughly 40% more paperwork than in 2024 for variable-income profiles. [7]

Standard document checklist for commission earners:

• ✅ Two years of T1 General tax returns (filed and assessed)
• ✅ Two years of Notices of Assessment (NOA)
• ✅ T4 or T4A slips for both years
• ✅ Recent pay stubs (last 30–90 days)
• ✅ Employment letter confirming commission structure, base salary (if any), and length of employment
• ✅ Bank statements (last 3–6 months, to show deposit patterns)
• ✅ Proof of down payment (90-day history)

For a complete breakdown of what to prepare, the Mortgage Document Checklist covers every item lenders typically request.

Edge case: If you have a base salary plus commission, lenders will count 100% of your base salary and add the two-year average of commissions on top. This combined figure is your qualifying income. [1] This is the most favorable scenario for commission earners.

How Does the Mortgage Stress Test Apply to Commission Earners?

The mortgage stress test applies to all borrowers in Canada, including commission earners. Lenders must qualify you at the greater of your contract rate plus 2%, or 5.25%, regardless of what rate you’re actually offered. [5]

This matters more for commission earners because the qualifying income is already averaged down. The stress test then applies an additional buffer on top of that.

Example:

• Qualifying income: $90,000/year
• Mortgage amount sought: $600,000
• Stress test rate: 7.25% (if contract rate is 5.25%)
• Required monthly qualifying payment: approximately $4,200
• Actual payment at contract rate: approximately $3,600 [7]

The gap between what you qualify for and what you’d actually pay can be significant. Understanding this calculation upfront helps commission earners set realistic purchase price targets.

What Credit Score and Debt Ratios Do Commission Earners Need?

In 2026, lenders have tightened credit and debt requirements for variable-income borrowers, including commission earners. [7]

Current benchmarks (2026):

The minimum credit score for conventional mortgages has moved up from 650 to 680 for variable-income profiles. [7] Commission earners with scores below 680 will face fewer lender options and likely higher rates.

To understand how your credit score affects mortgage approval, see Understanding the Role of Credit Scores in the Mortgage Approval Process in Canada.

Choose this path if:

• Score 720+: You qualify with most A-lenders at competitive rates.
• Score 680–719: A-lenders are accessible but may require stronger documentation.
• Score 620–679: B-lenders are the primary option; expect higher rates and fees.
• Score below 620: Private lending or a co-signer may be necessary. See Co-sign on a Mortgage in Canada for details.

What Are the Challenges and How Can Commission Earners Overcome Them?

Commission-based income earners face specific hurdles that salaried borrowers don’t. Knowing these in advance makes them manageable.

Top challenges and solutions:

Challenge 1: Income volatility Lenders see fluctuating income as higher risk. If your commission dropped in one year, the two-year average pulls your qualifying income down. Solution: Build a two-year track record before applying. If income is trending up, find a lender willing to use the most recent year.

Challenge 2: Tax write-offs reducing stated income T4A earners who deduct business expenses often show lower net income on their tax returns, which reduces qualifying income. Solution: Work with an accountant to balance tax efficiency with mortgage qualification. See Tax Smarts and Maximizing Benefits for the Self-Employed in Canada for strategies.

Challenge 3: Documentation burden Variable-income borrowers face more paperwork than salaried applicants, and requirements have increased in 2026. [7] Solution: Prepare all documents before starting the application. Use the checklist above as a starting point.

Challenge 4: Stress test squeezing qualification The stress test reduces purchasing power for all borrowers, but commission earners feel it more because their qualifying income is already averaged down. Solution: Consider a larger down payment to reduce the mortgage amount, or look at 30-year amortization options to lower monthly qualifying payments.

Challenge 5: Lender-by-lender variation Not all lenders treat commission income the same way. One bank might use the lower of two years; a monoline lender might use the average. Solution: Work with a mortgage broker who knows which lenders are most favorable for commission-based income profiles.

Should Commission Earners Use a Mortgage Broker or Go Directly to a Bank?

For most commission earners, a mortgage broker is the better starting point. Banks apply their own internal policies, which may be more conservative on commission income. A broker has access to multiple lenders and knows which ones use the most favorable income calculation methods.

Broker advantages for commission earners:

• Access to 30+ lenders, including A-lenders, B-lenders, and private options
• Knowledge of which lenders use two-year averages vs. lower-year calculations
• Ability to present your income story in the most favorable light
• No direct cost to the borrower (brokers are paid by lenders)

When to go directly to a bank:

• You have a long-standing relationship with the bank and strong salaried history alongside commission
• Your income is primarily base salary with a small commission component
• You’ve already been pre-approved and are comparing final rates

For a comparison of both approaches, see Mortgage Broker vs. Bank.

What Are Alternative and Private Lending Options for Commission Earners?

When A-lenders decline or offer insufficient mortgage amounts, B-lenders and private lenders fill the gap. These are legitimate options, not last resorts, for commission earners with specific circumstances.

B-Lenders (Alternative Lenders):

• Accept shorter income histories (sometimes one year)
• More flexible on income calculation methods
• Rates typically 1–2% higher than A-lenders
• Examples: Home Trust, Equitable Bank, CMLS

Private Lenders:

• Primarily asset-based lending (property value matters more than income)
• Useful for short-term bridging while building income history
• Rates significantly higher (8–12%+ range)
• Usually a 1–2 year solution before refinancing to a conventional lender

For more on private lending, see Getting a Mortgage with a Private Lender.

Choose B-lender if: You have 1–2 years of commission history, decent credit (620+), and 20%+ down payment. Choose private lender if: You’ve been declined by both A and B lenders, have strong equity or down payment, and need a short-term solution.

Conclusion: Actionable Next Steps for Commission Earners

Mortgage options for commission-based income earners in Canada are accessible, but they require more preparation than a standard salaried application. The path forward is straightforward when broken into clear steps.

Your action plan:

1. Build your two-year income record. If you’re new to commission work, wait until you have two full tax years filed before applying. One year may limit your lender options.

2. File your taxes on time and keep NOAs. Lenders need assessed returns. Unfiled taxes can disqualify an otherwise strong application.

3. Check and improve your credit score. Aim for 680+ before applying. See How to Improve Your Credit Score in Canada for practical steps.

4. Gather documents early. Collect two years of T1 returns, NOAs, T4/T4A slips, pay stubs, and an employment letter before you start shopping.

5. Work with a mortgage broker. A broker familiar with commission income profiles can save significant time and money by matching you to the right lender from the start.

6. Run the stress test math. Know your qualifying income and what mortgage amount it supports at stress test rates before you fall in love with a property.

7. Consider your down payment strategy. A larger down payment reduces the mortgage amount needed, making qualification easier and improving your lender options.

Commission-based income is not a barrier to homeownership in Canada. With the right documentation, the right lender, and a clear understanding of how income is calculated, commission earners can compete for the same mortgage products as any salaried borrower.

Frequently Asked Questions

Q: Can I get a mortgage with only one year of commission income? A: It’s possible but difficult with A-lenders. Most require two years of history. B-lenders and some alternative lenders may accept one year, typically with a larger down payment (20%+) and strong credit.

Q: Do lenders count 100% of my commission income? A: No. Most lenders use a two-year average, which may be lower than your current income. Some use the lower of the two years. Only select lenders use the most recent year if income is trending upward. [1]

Q: What if my commission income dropped last year? A: A significant drop will reduce your two-year average and your qualifying income. If the drop was temporary and income has recovered, document the reason clearly. A broker can help present your income story to lenders who consider context.

Q: Is commission income treated the same as self-employed income? A: Not exactly. T4 commission earners are treated more like employees. T4A commission earners are treated more like self-employed borrowers, with stricter requirements and often higher down payment expectations. [1]

Q: What credit score do I need for a commission-based mortgage in Canada in 2026? A: The current minimum for conventional mortgages is 680 for variable-income profiles. Scores below 680 push you toward B-lenders or private options with higher rates. [7]

Q: Can I include bonus income alongside my commission? A: Yes. Bonuses are typically averaged over two years, similar to commission. Consistent bonuses strengthen your application; one-time or irregular bonuses may be discounted or excluded.

Q: How does the stress test affect commission earners specifically? A: The stress test applies to everyone, but commission earners feel it more because their qualifying income is already averaged down. You must qualify at your contract rate plus 2% (or 5.25%, whichever is higher), which can significantly reduce your maximum mortgage amount. [5]

Q: Should I pay down debt before applying for a mortgage? A: Yes, if your total debt service (TDS) ratio is above 42–44%. Paying down high-interest debt improves your debt ratios and may also improve your credit score, both of which help your application.

Q: What if I have a base salary plus commission? A: This is the most favorable scenario. Lenders count 100% of your base salary and add the two-year average of commissions to get your total qualifying income. [1]

Q: Can a co-signer help a commission earner qualify? A: Yes. A co-signer with stable salaried income can strengthen an application where commission income alone falls short. See Co-sign on a Mortgage in Canada for how this works.
