The client
A home daycare operator in Regina, sole proprietor for four years, reported $34,000 of T1 net business income after legitimate T2125 deductions — a number that reflects sound tax planning on a business-for-self file, not the business’s real cash flow.

The problem
At the reported $2,833/mo, the file doesn’t work on paper — an entirely legitimate outcome of claiming every deduction the daycare is entitled to.
The reported-income arithmetic
- ▸Housing costs: qualifying payment $1,256 + property tax $275 + heat $110 = $1,641/mo
- ▸GDS against the reported $2,833/mo: $1,641 ÷ $2,833 = 57.9% — against CMHC’s 39% maximum.
Every dollar the T2125 return deducted was a real, allowed deduction. None of it means the business can’t support a $1,641-a-month housing cost — it means the tax return, read on its own, understates what the business actually generates.
The numbers
Once income is rebuilt with the standard self-employed add-backs, the same file changes completely — on a mortgage well under Canada’s average new mortgage amount.
| Structuring the insured loan | Amount |
|---|---|
| Purchase price | $180,000 |
| Down payment (5%) | −$9,000 |
| Base mortgage (95% LTV) | $171,000 |
| CMHC premium — 4.00% in the 90.01–95% LTV band, capitalized | +$6,840 |
| Total insured mortgage | $177,840 |
| Rate & payments | Figure |
|---|---|
| Contract rate (illustrative, not a quote) | 5.09% |
| Minimum qualifying rate | 7.09% |
| Monthly P&I at the qualifying rate | $1,256 |
| Monthly P&I at the contract rate | $1,043 |
Rebuilding income with the standard add-backs
| Add-back item | Annual | Monthly |
|---|---|---|
| Capital cost allowance (illustrative) | $10,800 | $900 |
| Business-use-of-home costs (illustrative) | $6,000 | $500 |
| Total added back to the $34,000 T1 net | $16,800 | $1,400 |
Added to the reported $2,833/mo, that brings qualifying income to $4,233/mo.
| Ratio | On the reported T1 alone | With standard add-backs restored |
|---|---|---|
| Income used | $2,833 | $4,233 |
| GDS ($1,641 housing ÷ income) | 57.9% ✗ | 38.8% ✓ |
| TDS (no other debt, same housing cost) | 57.9% ✗ | 38.8% ✓ |
The solution
An FCAA-licensed Saskatchewan mortgage broker rebuilt the file’s qualifying income the way lenders that work self-employed files regularly do — adding back capital cost allowance and the business-use-of-home portion of the T2125 return, both non-cash or personal-benefit items rather than money that left the business, using the standard add-back treatment for self-employed income.
Two years of T1s, the corresponding NOAs, and a letter from the client’s accountant confirming the daycare’s licensing and continuous operation went into the package, following the same documentation standard our guide to how Canadian lenders read self-employed income sets out, so the add-back numbers were not the broker’s assertion alone.
The outcome
Approved and funded insured at 95% LTV, 25-year amortization. GDS moved from 57.9% on the reported T1 net to 38.8% once the standard add-backs were restored, with TDS following the same path since there was no other debt on the file.
Saskatchewan has no verified transfer-tax fact — Information Services Corporation charges land-titles registration fees on closing, but the current fee schedule could not be independently confirmed, so no dollar figure is quoted here.
What to take from this file
- 01A low T1 net income does not mean a weak file. Legitimate T2125 deductions that lower reported income are exactly what standard self-employed add-backs exist to correct.
- 02CCA and business-use-of-home are the two most common add-backs. Both reduce reported net income without reducing what the business actually generates in cash.
- 03Document the add-back, don’t just assert it. An accountant’s letter and two years of T1s and NOAs turn an add-back from an opinion into a supportable number.
- 04Keep Saskatchewan closing costs qualitative. Land-titles registration fees apply, but the current schedule isn’t independently verified — quote none rather than guess.
