Two Directors, One Tax Debt: Why Documentation Saved Only One

The situation

Thalia and Sophia started their wholesale business as a side project eight years ago, while Thalia kept teaching elementary school and Sophia kept adjusting insurance claims. The business grew steadily, and about two years in they brought on a third co-founder, Kiran, who left his own job to run it full time out of a small warehouse near Lindsay. By the time the company was doing several million dollars a year in revenue, the arrangement had settled into a familiar shape: Kiran ran daily operations, signed the cheques, and handled the bookkeeper. Thalia and Sophia stayed on as directors and part-time contributors — reviewing numbers at quarterly meetings, weighing in on major decisions, but not touching the banking.

That division of labour worked well for years, and none of the three thought much about what it meant legally to be a director rather than just an owner. A director isn't only a title on a corporate registry; under Ontario and federal corporate law, directors carry personal legal duties and, in specific circumstances, personal financial exposure for the company's obligations — obligations that don't disappear just because someone else was handling that part of the business day to day.

That gap in understanding mattered once a rough eighteen months of supply delays and rising import costs squeezed the company's cash. Kiran, trying to keep suppliers and staff paid, started delaying the company's HST remittances and payroll source deductions — the portions of GST/HST collected from customers and income tax and CPP/EI withheld from employee paycheques that a corporation is required to hand over to the Canada Revenue Agency on a set schedule. He treated it as a short-term bridge, telling himself he'd catch up once a couple of large invoices cleared. Between the delayed shipments and a second cash crunch a few months later, it never fully did, and the gap between what the company owed the CRA and what it had actually remitted kept widening quietly in the background.

What the review found

A CRA audit caught up with the company about a year later. Over roughly fourteen months, the business had underremitted approximately $58,000 in HST and $37,000 in payroll source deductions — a shortfall of about $95,000. With penalties and accumulated interest, the corporation's total debt to the CRA had grown to roughly $115,000. The company negotiated a payment arrangement for that debt directly, but by then its cash position was thin enough that the CRA moved to a second track: personal liability against the company's directors.

Under the Income Tax Act and the Excise Tax Act, a corporation's directors can be personally assessed for its unremitted source deductions and GST/HST if the corporation itself doesn't pay. This is a deliberate design choice in the legislation — remittances are trust money, collected from employees and customers on the government's behalf, and Parliament wanted directors to feel that responsibility personally, not just on the company's balance sheet. The one significant shield available to a director is the due diligence defence: a director isn't liable if they can show they exercised the degree of care, diligence, and skill a reasonably prudent person would have exercised in comparable circumstances to prevent the failure.

All three co-founders received personal assessment notices for approximately $95,000 each — the unremitted amount, plus interest that had continued to accrue since the corporate assessment. Thalia and Sophia came to Treadstone Law together, both facing personal debt roughly equal to a year of Thalia's teaching salary, neither having ever handled the company's remittances directly.

What we did

1. Separated the two directors' actual conduct. The due diligence defence turns on what each individual director knew and did, not on the group's collective failure. Thalia and Sophia had different levels of involvement and, it turned out, very different paper trails, so we treated their positions as two separate cases from the outset even though they were assessed for the same debt.
2. Reconstructed Thalia's record of oversight. Thalia had a habit, going back years, of emailing the bookkeeper after every quarterly review to confirm remittances were current — a two-line message, sent consistently, that she'd never thought of as a legal safeguard. We pulled that email history together with meeting notes where she'd raised the same question out loud. It showed a pattern of a reasonably prudent director asking the right question repeatedly, not a director who looked away.
3. Assessed Sophia's weaker position honestly. Sophia had asked similar questions at meetings but rarely in writing, and on at least two occasions had accepted a verbal assurance from Kiran without following up. We told her directly that her defence was weaker and that a full vacating of her assessment was unlikely — better to know that early than to build a case on a foundation that wouldn't hold.
4. Filed a notice of objection for each director with the CRA's appeals division, the formal process for disputing an assessment, supported by the documentary record specific to each. Thalia's submission leaned on her contemporaneous emails and the corrective action taken once the shortfall came to light — she was the one who pushed for a new bookkeeper and a segregated remittance account once the problem surfaced. Sophia's submission focused on limiting the assessment rather than eliminating it, given the gaps in her paper trail.
5. Negotiated a settlement for Sophia once it was clear a full defence wasn't realistic, reducing her personal exposure by demonstrating the corrective steps she had taken alongside Thalia after discovery, even without the earlier documentation.
6. Advised on governance changes going forward so the company wouldn't be back in this position — a dedicated trust sub-account for HST collected, a monthly reconciliation sent to all three directors, and a standing agenda item at every board meeting confirming remittance status in writing, whether or not a question was ever asked.

The outcome

The CRA's appeals division vacated Thalia's personal assessment in full. Her documented pattern of asking about remittance status, and her role in pushing for corrective action once the shortfall surfaced, satisfied the due diligence defence — the record showed a director who had done what a reasonably prudent person in her position would do, given that she wasn't the one controlling the company's banking.

Sophia's outcome was harder. Without the same paper trail, her objection couldn't support a full defence, and she settled her personal assessment at roughly $40,000 — a real reduction from the original $95,000, reflecting the corrective steps taken after discovery, but still a significant personal debt she is paying off over several years. Kiran, who had controlled the remittances directly and had the least basis for a due diligence defence of the three, was not our client and faced the fullest exposure on his own assessment.

The company itself survived, on a payment arrangement for its own remittance debt and with the new governance habits in place. Two years on, Thalia and Sophia still run the business together with Kiran, though the working relationship carries the weight of what the shortfall cost each of them personally and unevenly.

What stayed with Thalia afterward wasn't the relief of the vacated assessment so much as how close the margin had been. The habit that saved her — a two-line email after every quarterly review — had never felt like anything more than tidiness at the time. She hadn't started sending those emails because she suspected a problem; she had started because she liked having a written record to look back on. It was only once the CRA came asking that the difference between a habit and a legal defence became visible. Sophia had asked the same kinds of questions just as often, in the same meetings, but out loud rather than in writing, and that difference in form rather than substance turned out to separate a vacated assessment from a $40,000 personal debt.
