Getting a Mortgage When You're Self-Employed in Canada
Prime lenders qualify self-employed borrowers on a 2-year average of Line 150 (net income) from their T1 Generals — which usually under-represents what you actually earn. Strong applicants get prime-rate approvals with the right documentation, but a meaningful share route through stated-income programs, alternative lenders, or CMHC's Self-Employed Program — each with a different rate and down-payment trade-off.
Who this is for
Self-employed sole proprietors, incorporated business owners, and commissioned contractors — typically with 2+ years of business income but variable or optimized-for-tax earnings.
- Qualifying income (prime, strict)
- $75k (2-yr average of Line 150)
- Qualifying income (prime, with add-backs)
- ~$140k-160k
- Qualifying income (CMHC SEP)
- Up to 100% of stated income, 10% down
- Alternative lender range
- Rate premium ~75-150bps vs prime
Framework
The three qualification paths
1. Full prime with T1 averaging. Two years of T1 Generals, both NOAs, 2 years of business financial statements (if incorporated), HST filings, and articles of incorporation. Lender uses the lower of Line 150 averages unless trending up. Best rates, strictest documentation.
2. CMHC Self-Employed Program (stated income). For borrowers with fewer than 2 years of tax-reported income or whose reported income materially understates true earnings. Stated income can be used with reasonableness tests (industry averages, business deposits). Requires 10% down minimum on insured, and the premium is elevated vs standard insured.
3. Alternative / B-lender. Manulife, Home Trust, Equitable, Haventree, and monolines accept bank-statement qualification (12-24 months of business deposits) or use adjusted gross. Rates run 75-150 bps above prime and most charge a 1% lender fee. Useful bridge for 12-24 months until you can qualify prime.
Add-backs that prime lenders sometimes allow
If you're incorporated, ask the lender whether they allow add-backs for (a) retained earnings taxed at the small-business rate, (b) owner-paid expenses that aren't truly business costs (vehicle, home office beyond reasonable), (c) depreciation and CCA. Policies vary by lender — some allow 100% add-back of retained earnings, others allow 0%. A broker with a wide lender panel is worth more than a bank branch here because the spread across policies is large.
Key considerations
- Start your mortgage conversation 6-12 months before you need it — this is enough time to adjust what you report on your T1 for one tax year if needed.
- File your HST and personal taxes on time every year. Arrears are an instant decline at most prime lenders, even if paid.
- Commingled personal/business banking makes bank-statement qualification harder. Separate your business account before you apply.
- If your business is <2 years old, CMHC's Self-Employed Program or a B-lender is usually your only route — no amount of cash reserves substitutes for time-in-business at prime.
Common mistakes
- Writing off too aggressively the year before you apply — every dollar of deduction reduces Line 150 by a dollar, which reduces qualifying mortgage by ~4-5×.
- Assuming your accountant's 'optimized' tax strategy is also a mortgage-optimized strategy. They're usually in tension.
- Applying direct to a big bank branch — most branches have no policy authority on self-employed files and will default to the strictest read.
Action steps
- 01Pull your last two NOAs and calculate your 2-year Line 150 average. This is your prime-lender starting point.
- 02Decide whether you're willing to report more income next tax year to qualify prime — the incremental tax is usually less than a 150 bps rate premium over 5 years.
- 03Engage a broker with both prime and alternative access, not a single-lender rep.
- 04Pre-qualify 90-120 days before you need the funds so you have time to correct documentation gaps.
