The short answer
Yes, you can buy. Self-employment and commission income are ordinary in Calgary — consultants, trades, energy-sector contractors, realtors, salespeople, medical professionals in professional corporations. Lenders have been underwriting this for decades.
What changes is the evidence. Salaried income is proved with a letter and a pay stub. Self-employed income is proved with a file. Everything below varies by lender, and none of it is a promise of approval.
How a lender looks at it
Three questions drive the underwriting:
- How long has the income existed? Lenders want history. Two years of documented income is the common reference point, though the requirement and the flexibility around it vary by lender and by programme.
- Is it stable, and which direction is it moving? Variable income is usually averaged. An average of a strong year and a weak year is not a strong year. A declining trend is often treated more conservatively than the average alone would suggest.
- What number can be used? This is the crux, and it is where self-employed buyers are most often surprised.
The write-off trap
If you are a sole proprietor, most lenders qualify you on your net income — what is left after the deductions your accountant worked hard to maximise. Every legitimate expense you wrote off to reduce tax also reduced the income a lender can count.
Some lenders will add back certain non-cash or discretionary deductions, and some will gross up net income by a set factor to approximate a comparable salaried figure. Whether that applies, and by how much, varies by lender and by programme. It is not something to assume.
The conversation to have with your accountant is not "how do I pay less tax this year" but "what do my last two returns look like to a mortgage underwriter". Those two goals point in opposite directions.
Incorporated buyers have a different version of the same problem: if the profit stayed in the company rather than coming out as salary or dividends, the lender may or may not be willing to look through to it. Some will, with the corporate financials. Some will not.
What to have ready
Assemble this before you start looking, not after you have found a house. A file that is already complete is the difference between writing an offer this weekend and watching it go.
- Two years of complete T1 General returns — the whole return, not just the summary page.
- The matching Notices of Assessment, and proof that any balance owing has been paid.
- For an incorporated business: two years of financial statements, and the articles of incorporation.
- Business licence or registration, and a GST registration where you have one.
- Recent business bank statements.
- For commission income: two years of T4 or T4A slips, recent pay statements, and a letter from the employer confirming the arrangement.
- A paper trail for the down payment — 90 days of history on every account it came from, and a clear record if any of it was a gift. How gifted down payments work.
The programmes that exist
Insured self-employed programmes exist in Canada and are used routinely, including for borrowers whose declared income does not fully reflect the business. Terms, qualifying rules and pricing are lender-specific and change — which is exactly why this belongs with a broker rather than in an article.
Beyond that, there are lenders outside the federally regulated bank space who price differently and document differently. That is a legitimate path, not a failure. It usually involves a larger down payment and a higher cost, and the sensible version of it comes with a plan to move to conventional financing later.
Everything about qualifying is the same for you as for anyone else: the ratios and the stress test still apply. Only the income line is derived differently.
Why this comes up so much in Calgary
A large share of this city's income is variable by design. Bonus-heavy energy roles, consulting through a personal corporation, trades contractors who bill by the job, and a commission-based sales economy are all normal here. So are the cycles — Calgary's income history has real dips in it, and an average taken across a downturn year is a different number than an average taken across two strong ones.
Two practical consequences for a Calgary buyer:
- Timing. If your first full year of self-employment ends in March, waiting for that Notice of Assessment can change what you qualify for far more than shopping rates will.
- Sequencing. Do not restructure how you pay yourself in the same year you want to buy. Lenders look backwards, not at the plan.
What to do next
Get in front of a mortgage broker early — before the house, before the pre-approval expires, before the tax filing that could help or hurt. A broker who sees self-employed files regularly will know which lenders treat your structure sensibly, and will tell you what your file is missing while there is still time to fix it.
We are REALTORS®. We do not underwrite, and we will not tell you what you qualify for. What we will do is not waste your weekends on houses your file cannot support, and make sure your financing condition period is long enough for a file that takes real underwriting rather than an automated approval.

One more thing worth saying plainly: being self-employed is not a black mark and you should not present it apologetically. Lenders are not suspicious of business owners. They are constrained by what they can document. Give them a clean, complete, boring file and the conversation is the same one a salaried buyer has.
