Interest Relief After a Cancer Diagnosis Halted a Trucking Business

When a small corporation owner in Ottawa was sidelined by cancer treatment, his company's remittances stopped and interest piled up. A taxpayer relief request cut the damage — but could not undo all of it.

The situation

Kostas ran a small corporation out of Ottawa with two trucks on the road, hauling freight on long-haul routes across Ontario and into Quebec. He drove one of the trucks himself and employed one other driver. His wife, Thao, worked as a hairdresser and had no role in the company beyond occasionally answering the phone when Kostas was on the road. The business was modest but steady: enough to cover a mortgage, two vehicle leases, and the corporation's monthly source deduction and HST remittances to the Canada Revenue Agency (CRA).

The corporation's paperwork had always run on Kostas's own schedule. He kept a shoebox of fuel receipts and invoices, reconciled them on Sunday evenings, and filed remittances himself through the CRA's online portal a few days before each due date. It was not an elegant system, but for six years it had worked without a single missed payment, and Kostas saw no reason to pay someone else to do a job he was capable of doing himself.

In the fall, Kostas was diagnosed with an aggressive form of cancer. He began chemotherapy within weeks, and by early winter he could no longer drive. The second driver kept one truck running, but revenue fell by more than half, and the second truck sat parked in a lot for months because there was no one to drive it and no money to hire a replacement. Kostas spent much of the following four months in and out of hospital for treatment cycles that left him too unwell to think about invoices, let alone reconcile them. The corporation's bookkeeping — normally handled by Kostas himself on weekends — stopped almost entirely. Remittances for payroll source deductions and HST were missed for four consecutive periods, and the CRA's automated systems began issuing arrears notices to a business address that, for weeks at a time, no one was checking.

What the review found

By the time Kostas was well enough to deal with paperwork again, the corporation owed the CRA roughly $22,000 in unremitted source deductions and HST, plus interest that had been compounding daily since each missed due date. A friend who did some bookkeeping for Thao's salon, Mai, helped Kostas gather the corporation's records and pointed him toward Treadstone Law when a CRA collections letter arrived threatening further enforcement action.

Our review confirmed the underlying debt was accurate — the corporation genuinely owed the remittances, and there was no dispute about that. The issue was the interest. Under the CRA's rules, arrears interest accrues automatically and compounds daily from the missed due date, regardless of the reason for the delay. By the time Kostas engaged us, interest and penalties had added roughly $9,000 on top of the $22,000 principal, for a total owing of about $31,000. Left unaddressed, that figure would keep growing every month the balance sat unpaid.

The corporation had no realistic way to pay the full amount at once. Revenue had partly recovered as Kostas returned to part-time driving, but the business was still catching up on other bills that had been deferred during his treatment. The immediate goal was to stop the bleeding: reduce what was owed to something the corporation could actually pay off, and buy enough breathing room to avoid a garnishment or a lien against the business.

What we did

  1. Filed a taxpayer relief request. The Income Tax Act and the Excise Tax Act (which governs HST) both give the CRA discretion to cancel or waive penalties and interest — though never the underlying tax debt itself — in specific circumstances, including serious illness that prevented a taxpayer from meeting their obligations. We prepared a formal request explaining the timeline of Kostas's diagnosis, treatment, and hospitalizations, and how each missed remittance period lined up with a period when he was medically unable to manage the corporation's finances.
  2. Gathered supporting medical documentation. The CRA does not take a taxpayer's word for a serious illness; it expects evidence. We worked with Kostas to obtain a letter from his treating oncologist confirming the diagnosis, the treatment schedule, and the periods of hospitalization, and matched those dates against the corporation's remittance due dates period by period.
  3. Drew a clear line between the illness period and the rest. Relief requests succeed or fail on precision. We were careful not to overreach: the request asked the CRA to cancel interest only for the months Kostas was actively undergoing treatment or hospitalized, not for periods before the diagnosis or after he had returned to work. A request that claims more than the facts support tends to lose credibility on the parts that are actually strong.
  4. Proposed a payment arrangement for the remaining balance. Because the corporation could not pay the full amount in one instalment, we negotiated a monthly payment plan with the CRA's collections officer for the principal and any interest that was not waived, set at an amount the corporation's recovering revenue could sustain without triggering another default.
  5. Advised on go-forward compliance. We recommended Kostas move the corporation to a bookkeeper on a regular schedule rather than handling remittances himself, and set up calendar reminders tied to each due date, so a future disruption — illness or otherwise — would not silently compound into another six-figure-style debt.

The outcome

The CRA accepted the core of the relief request. It cancelled interest for the period matching Kostas's documented treatment and hospitalization — roughly $5,500 of the $9,000 in accrued interest — but declined to waive interest for the weeks before his diagnosis was confirmed and the period after he had resumed part-time work, on the basis that the corporation could reasonably have managed its remittances during those windows. The corporation was left owing about $22,000 in principal plus roughly $3,500 in interest that stood, for a total of about $25,500, down from the original $31,000.

That was a real reduction — about $5,500 saved — but it was not the full relief Kostas had hoped for. The CRA's discretion under the relief provisions is exactly that: discretionary, and it is applied narrowly to the period the evidence actually supports. The corporation entered a payment plan for the remaining balance and, as of this writing, has kept current on it without missing an instalment.

This was not a case where the firm could make the debt disappear, and it was important to be honest with Kostas about that from the outset. The relief provisions exist to excuse interest that accrued because of genuine hardship, not to erase a tax debt that was otherwise valid. What the process did accomplish was meaningful: it stopped daily compounding on a growing balance, it converted an unmanageable lump sum into a plan the business could actually sustain, and it avoided the kind of enforcement action — a wage garnishment on Kostas's own pay, or a lien registered against the corporation's assets — that could have shut the business down entirely while he was still recovering.

What you can learn from this

  • Interest on unremitted source deductions and HST compounds daily and does not pause for hardship on its own — a taxpayer relief request has to be filed; relief is never automatic.
  • Relief under the Income Tax Act and Excise Tax Act only ever applies to penalties and interest, never to the underlying tax debt itself. Budget for paying the principal regardless of how the request turns out.
  • The CRA expects documentary evidence, not just an explanation. A letter from a treating physician with specific dates carries far more weight than a general account of being unwell.
  • A relief request is stronger when it asks for exactly what the evidence supports. Claiming interest relief for periods outside the documented hardship window can undermine the credibility of the whole request.
  • If a business cannot pay a CRA debt in full, proposing a realistic payment plan before enforcement action starts is usually far better than waiting for a collections officer to impose one.
