The client
A 14-on/7-off rotational oilfield worker in Fort McMurray, stable T4 income of $9,200/mo, running a small equipment-repair sole proprietorship on his weeks off. The side business is real and growing — two full T1 years, net income rising from $9,600 to $13,200 — but it is not the primary income, and it was not supposed to complicate the T4 side of the file at all.

The problem
The moment the application showed any self-employment income at all, the first lender's intake process flagged the entire file — T4 job included — for full self-employed documentation: two years of Notices of Assessment, financial statements, and business registration, for both incomes. The T4 employment needed none of that; it needed paystubs and a letter of employment, exactly as it would on a file with no self-employment at all.
Why the file didn't need to be treated that way
- ▸T4 income: $9,200/mo, documented with paystubs, T4 slips and a letter of employment — no self-employed conventions apply to it at all.
- ▸Side business income: two full T1 years, averaged the standard self-employed way to $950/mo.
- ▸Combined qualifying income: $10,150/mo — once each income is documented under the rules that actually apply to it.
Running the whole file as if both incomes needed the same paperwork would have meant a second Notice-of-Assessment request for a T4 job that was never in question, adding delay for no underwriting benefit.
The numbers
This is an uninsured refinance — refinances are not eligible for CMHC default insurance regardless of loan-to-value, so the file qualifies under OSFI's minimum qualifying rate for uninsured mortgages, with no 39%/44% ceiling.
| The consolidated refinance | Amount |
|---|---|
| Existing mortgage balance | $230,000 |
| Truck loan payout | +$25,000 |
| Personal loan payout | +$20,000 |
| New consolidated balance | $275,000 |
| Rate & payments | Figure |
|---|---|
| New contract rate — 5-year fixed (illustrative, not a quote) | 5.29% |
| Minimum qualifying rate — contract + 2% | 7.29% |
| Monthly P&I at the qualifying rate — the ratios run on this, 22-year amortization | $2,075 |
| Monthly P&I at the contract rate — what he actually pays | $1,756 |
TDS on the correctly-split file
| TDS line | Figure |
|---|---|
| Housing (qualifying payment + $290 tax + $140 heat) | $2,505 |
| Combined income (T4 + two-year self-employed average) | $10,150 |
| TDS | 24.7% |
Because this file is uninsured, this TDS figure is informational rather than a pass against a regulatory ceiling — but it shows the correctly-classified file was never a close call once the T4 income stopped being run through an unnecessary stress-test documentation loop.
The solution
An RECA-licensed mortgage associate reset the file's documentation path before resubmitting it.
First, split the income types correctly. The T4 job was documented the ordinary way — paystubs, T4 slips, a letter of employment confirming rotational schedule and tenure. Only the side business's income was run under the self-employed two-year-average convention, since only that income is self-employed.
Second, built the consolidation into a single refinance. Folding the $25,000 truck balance and $20,000 personal loan into the new $275,000 mortgage retired $960/mo of separate debt payments, more than covering the increase in the mortgage payment itself.
Third, documented both years of the side business cleanly so its inclusion needed no further explanation once the file reached underwriting.
The outcome & the monthly math
Funded uninsured at 5.29%, 22-year amortization. Because this is a refinance rather than a purchase, no provincial transfer tax applies at all — and Alberta has no land transfer tax on purchases either. Alberta's own registration fees for a mortgage of this size apply at closing, but the current fee schedule could not be independently verified, so no dollar figure is given here.
The real result was cash flow: retiring $2,402/mo of separate payments and replacing them with a $2,075/mo qualifying payment on the new mortgage nets $327/mo back — before counting whatever he continues to bank from the side business.
What to take from this file
- 01A self-employed income source does not make the whole file self-employed. Document each income type under the rules that actually apply to it, not the strictest rule the file contains.
- 02Consolidation math should compare total obligations, not just the new mortgage payment. A larger mortgage payment can still mean a smaller total monthly outlay once separate debts disappear.
- 03Refinances carry no default-insurance premium and no provincial transfer tax — two costs a purchase file would otherwise have to plan for.
- 04Two full T1 years of a side business, cleanly documented, need no further justification. The paperwork itself does the persuading.
Sources
Every regulatory figure in this file traces to one of these primary sources. Client details and anything that varies by lender are illustrative, as flagged below.
- ▸OSFI — Minimum qualifying rate for uninsured mortgages — the minimum qualifying rate — greater of contract rate + 2% or 5.25%.
- ▸Provincial/territorial mortgage-broker legislation fetched directly (bclaws.gov.bc.ca, legisquebec.gouv.qc.ca, fcaa.gov.sk.ca, web2.gov.mb.ca, nslegislature.ca, assembly.nl.ca) plus FCNB's own site for NB and CanLII's index for PE — see notes for per-province method — provincial mortgage regulators and licence titles.
Illustrative in this file — lender-specific, not rules:
- ▸5.29% refinance contract rate / 4.89% existing rate — rates move daily; neither is a quote.
- ▸the TDS figure — this file is uninsured, so there is no CMHC ratio ceiling -- the number is informational, not a pass/fail line.
- ▸Alberta closing costs — Alberta has no land transfer tax, and the province's registration-fee schedule could not be independently verified, so no dollar figure is given here.
