The client
A self-employed business owner near Cowansville has her corporation carry a lakeside chalet on its books, using it personally on weekends without ever being charged rent.
Fair market monthly rent for the chalet
$1,400
Corporation's original T2 net income
As filed, chalet costs deducted
Refinance amount
$265,000
Original qualifying income used
$7,800/month
The problem
Under subsection 15(1) of the Income Tax Act, personal use of a corporation's property -- a house, a car, a chalet -- without paying fair market rent is a taxable benefit to the shareholder, not a deductible business expense to the corporation. The corporation cannot claim the chalet's carrying costs against its own income, and the shareholder must include the value of the benefit on her own return.
What the first read of the file got backwards
- ▸The corporation's T2 return had deducted the chalet's carrying costs as an ordinary business expense, understating the corporation's true taxable income
- ▸Because those costs were treated as a deduction, they were never separately attributed to the owner personally, understating HER income by the same amount
- ▸CRA's own guidance is explicit: the corporation reports the benefit on a T4A slip, and the shareholder includes the full amount on her own return -- it belongs on neither side by default
A first lender's file simply used the corporation's T2 net income, as filed, to build a retained-earnings gross-up for her personal qualifying income. It never asked whether that net income figure was itself correct -- or whether $16,800 a year of her own income was sitting, mislabelled, inside the corporation's expenses instead.
The numbers
Once the shareholder benefit was correctly attributed to her own income, recalculating her qualifying income was straightforward arithmetic.
| The shareholder benefit, correctly attributed | Amount |
|---|---|
| Fair market rent for the chalet ($1,400 x 12 months) | $16,800 |
| Original monthly qualifying income | $7,800 |
| Corrected monthly qualifying income | $9,200 |
| Total debt service, her own income | Original | Corrected |
|---|---|---|
| Payment at the qualifying rate (6.60%), 25 years | $1,791 | $1,791 |
| Property tax + heat | $380 | $380 |
| Car loan | $220 | $220 |
| Total debt service | 30.7% | 26.0% |
26.0% against the corrected $9,200/month figure is a meaningfully stronger file than 30.7% against the original -- the refinance amount never changed; only whether the $16,800 shareholder benefit was properly counted as hers, consistent with how an incorporated owner's own income should actually be built up.
The solution
A courtier hypothécaire licensed under Quebec's Act respecting the distribution of financial products and services treated the corporation's T2 net income as a starting point to be tested, not a finished figure to gross up as filed.
First, asked what corporate-owned assets the owner used personally, a question a standard gross-up conversation often skips once a T2 is already in hand.
Second, had the accountant calculate the chalet's fair market rental value and confirm the resulting shareholder benefit, along with whether it had actually been reported on the owner's own return.
Third, rebuilt the qualifying-income calculation adding the $16,800 benefit to her personal side, rather than leaving it buried inside the corporation's deducted expenses.
The outcome
The refinance funded at 4.60% using the corrected $9,200/month qualifying income, with total debt service at 26.0% rather than the 30.7% the original, understated figure would have produced.
Because this is an uninsured refinance, CMHC's ratio maximums do not apply directly; both TDS figures are informational, shown to demonstrate the effect of the correction.
What to take from this file
- 01Personal use of corporate property without fair market rent is a taxable shareholder benefit under section 15(1), not a business expense. The corporation cannot deduct it, and the shareholder must report it personally.
- 02A gross-up built only on the T2's filed net income can understate the owner's real personal income. Ask what corporate assets the owner personally uses before accepting the figure as final.
- 03Have the accountant calculate fair market rent and confirm the benefit was actually reported. Documentation, not assumption, is what makes the correction defensible.
- 04This correction usually helps the file, not hurts it. Properly attributed, a shareholder benefit is real personal income the borrower was already receiving.

Illustrative in this file — lender-specific, not rules:
- ▸4.60% contract rate — rates move daily; not a quote.
- ▸the $1,400/month fair market rent figure — this property's own market-rent estimate; every property's fair market rent is individual.
- ▸the 30.7% / 26.0% TDS figures — this is an uninsured refinance, so there is no CMHC ratio ceiling -- the numbers are informational, shown to isolate the effect of the correction.
