The client
A self-employed Red Deer rig and well-site contractor buying a $372,000 home at 10% down, invoiced through several different operators and staffing agencies each year, each of whom issues its own T4A rather than a T4.
Purchase price
$372,000, Red Deer
10% down, insured
Year 1 income (T2125)
$7,600/mo
several payers, one continuous business
Year 2 income (T2125)
$8,400/mo
same business, different payers
How he's paid
T4A slips from each operator/agency, box 048
The problem
A first lender's automated income-verification tool read each T4A issuer as a separate, short-term employer — treating a genuinely continuous, single self-employed business as a string of unstable jobs. A T4A for services, box 048, is CRA's own confirmation that a payment is fees for services, not employment income; it is not a substitute T4, and receiving several of them in a year does not mean several employers.
What the tool got backwards
- ▸Each well-site operator and staffing agency issues its own T4A rather than sharing one slip between them
- ▸The T4A itself confirms self-employment income, not employment — it is CRA's 'fees for services' slip
- ▸The borrower's own T2125 reported all of it as one continuous business, filed once per year
A mortgage associate reading the file correctly the first time would have seen one business with several clients, not five jobs with five different employers.
The numbers
Once the T4A slips were read as what they actually are, the two-year average stood on its own.
| Qualifying on the T2125 | Amount |
|---|---|
| Purchase price | $372,000 |
| CMHC premium (3.10% at 90% LTV) | +$10,379 |
| Total insured mortgage | $345,179 |
| Total debt service | Figure |
|---|---|
| Payment at the qualifying rate (7.00%), 25 years | $2,418/mo |
| Property tax | $285/mo |
| Heat (lender estimate) | $115/mo |
| Car loan | $245/mo |
| Total debt service, on the two-year T2125 average | 38.3% |
38.3% clears comfortably inside CMHC's 44% ceiling once the file is qualified on the actual $8,000/mo two-year average shown on proving continuance on contract and T4A income, rather than the fragmented read the automated tool produced.
The solution
A mortgage associate licensed under RECA's Real Estate Act Rules moved the file the moment the automated tool's employer count stopped matching the borrower's own tax filings.
First, pulled the T2125 for both years. Each year showed one net self-employment income figure, filed once, with a schedule of the different well-site operators and agencies the income came from.
Second, supplied the full set of T4A slips alongside the T2125. Confirmed each slip was issued in box 048, CRA's own designation for fees for services rather than employment income.
Third, moved the file to a lender whose underwriter reads a T4A for services correctly. Consistent with the standard self-employed two-year average treatment, once the income was recognized as coming from one business, not five.
The outcome
The purchase funded insured at 35.2% GDS and 38.3% TDS, on income correctly read as one continuous self-employed business rather than five separate short-term jobs.
Because this file is CMHC-insured, both the 35.2% GDS and 38.3% TDS figures are measured against CMHC's real 39%/44% ceilings, and clear them with room to spare.
What to take from this file
- 01A T4A for services is not a substitute T4. CRA issues it, box 048, specifically to confirm the payment is fees for services — a self-employment signal, not an employment one.
- 02Multiple T4A issuers can still mean one business. A contractor invoicing several clients in a year is not the same as holding several short-term jobs.
- 03The T2125, not the T4A count, is the real record of the business. It shows the income as one filing, regardless of how many slips fed into it.
- 04An automated tool's default read isn't always right. Where the output contradicts the borrower's own tax filings, the filings win.
