The client
A long-haul owner-operator running a single tractor unit under his own authority, buying his first detached home in North Bay. Two filed T1 years show net T2125 business income of $72,000 and $84,000 — solid and growing — but both years carry heavy capital cost allowance (CCA) on the truck, a legitimate, entirely non-cash deduction that shrinks the number a lender sees on the return.

The problem
The bank’s underwriter took the net T2125 figure exactly as filed — the correct starting point for self-employed income, but not the finishing point. CCA is one of the few deductions that reduces taxable income without reducing what actually landed in the business’s bank account, and this file leaned on it heavily.
Net income, as filed
- ▸Two-year average net income: ($72,000 + $84,000) ÷ 2 = $78,000/yr, $6,500/mo
- ▸Liabilities: mortgage payment at the qualifying rate, property tax, heat, car loan and credit card minimum
- ▸TDS: 55.8% against CMHC’s 44% maximum. Declined.
Nothing about the file was wrong — the truck really was depreciating on schedule, and the write-off really did reduce tax owing. But a lender reading the T1 net figure alone sees a smaller income than the business actually generates in cash. Our glossary entry on add-backs covers exactly this class of deduction — the ones a lender can restore because they never left the owner’s pocket.
The numbers
At 10% down this is an insured file: CMHC’s maximums — GDS 39%, TDS 44% — apply as hard numbers.
| Structuring the insured loan | Amount |
|---|---|
| Purchase price | $420,000 |
| Down payment (10%) | −$42,000 |
| Base mortgage (90% LTV) | $378,000 |
| CMHC premium — 3.10% in the 85.01–90% LTV band, capitalized | +$11,718 |
| Total insured mortgage | $389,718 |
The minimum down payment at this price is $21,000 — 5% of the purchase price, since $420,000 sits under the $500,000 tier boundary — so $42,000 clears it comfortably.
| Rate & payments | Figure |
|---|---|
| Contract rate — 5-year fixed (illustrative, not a quote) | 4.99% |
| Minimum qualifying rate — greater of contract + 2% and 5.25% | 6.99% |
| Monthly P&I at the qualifying rate — the ratios run on this | $2,727 |
| Monthly P&I at the contract rate — what he actually pays | $2,264 |
Income — before and after the CCA add-back
| Income treatment | Monthly |
|---|---|
| Two-year average net T2125 income ($72,000 + $84,000 ÷ 2) | $6,500 |
| CCA claimed, two-year average ($24,000 + $21,600 ÷ 2) | +$1,900 |
| Qualifying income with the CCA restored | $8,400 |
TDS — where the CCA add-back moves the file
| TDS line | Net income only | Net income + CCA add-back |
|---|---|---|
| Housing costs (PI + tax + heat) | $3,157 | $3,157 |
| Vehicle loan + credit card minimum | $470 | $470 |
| Income used | $6,500 | $8,400 |
| TDS vs. the 44% cap | 55.8% ✗ | 43.2% ✓ |
GDS with the add-back restored comes to 37.6%, under the 39% cap. As with GDS, the add-back changes nothing about the truck or the business — only how much of its real cash flow the lender is willing to recognize.

The solution
An FSRA-licensed Ontario mortgage agent worked the file in two stages.
First, rebuilt the income the way a lender that add-backs would see it. CCA is deducted for tax purposes but never leaves the business as cash the way, say, fuel or a lease payment does. Restoring it is not aggressive accounting — it is standard practice at lenders whose self-employed policy recognizes it, and our worked GDS and TDS examples show the same principle applied across several file types.
Second, matched the file to a lender publishing a CCA add-back policy and packaged the proof so the underwriter never had to guess at the schedule:
The CCA schedule itself did the convincing: two consecutive years of the same depreciation pattern on the same asset, filed and assessed, is about as documentable as a non-cash add-back gets.
The outcome & the closing math
Approved and funded: insured at 90% LTV, 25-year amortization, 5-year fixed. For broader context on how a mortgage this size sits against the national picture, see our data on the average new mortgage amount in Canada. The last piece of broker work was making sure the cash needed at closing, beyond the down payment, was budgeted and documented.
| Cash due at closing (beyond the down payment) | Amount |
|---|---|
| Ontario land transfer tax on $420,000 — 0.5% / 1.0% / 1.5% / 2.0% marginal brackets; North Bay adds no municipal LTT | $4,875 |
| Ontario RST on the insurance premium — 8% × $11,718; the premium itself is capitalized, but the tax on it is cash at closing | $937 |
| Legal fees, title insurance & adjustments | varies |
What to take from this file
- 01CCA is the most common add-back on a trucking or heavy-equipment file. It is a real, legitimate deduction — and a real, legitimate add-back, at lenders whose policy recognizes it.
- 02Restoring the add-back moved TDS by more than twelve points on this file. Net income alone told an incomplete story of what the business actually generates in cash.
- 03Two consecutive filed years on the same asset makes the add-back easy to document. A single year of CCA is a data point; two years of the same pattern is a trend a lender can rely on.
- 04The qualifying rate still decides the ratios. This file qualifies at 6.99% and pays at 4.99% — a $463-a-month gap between the two payments.
- 05Budget the closing cash, not just the down payment. Land transfer tax plus the RST on the premium added $5,812 in cash before legal fees.
