ii) Draws to the dentist;
iii) Any nondeductible fringe benefits paid to employees;

Tax Department’s Perspective:
Since the loan was used and can be traced to business expenses, the interest on the loan is tax deductible as such interest was incurred in order to earn income.
It is important that the audit trail is strictly adhered to, otherwise CRA, the Tax department, could deny the deduction.
