Running a corporation in Canada comes with significant responsibilities — and few carry more personal risk than your obligations around payroll remittances. Under the Income Tax Act (ITA), directors of a corporation can be held personally liable for amounts the corporation owed to the Canada Revenue Agency but failed to remit. This is not a technicality buried in fine print. CRA pursues directors aggressively, and the resulting assessments can be financially devastating. Understanding directors' liability for CRA debts in Canada — and how to protect yourself — is essential for anyone sitting on a corporate board.
Section 227.1 of the Income Tax Act establishes the foundation of directors' liability in Canada. When a corporation fails to remit employee source deductions to the CRA, every director of the corporation at the time of the failure is jointly and severally liable with the corporation for those amounts, plus any related interest and penalties.
This is a personal liability. CRA does not need to chase the corporation first and fail before coming after you — it simply needs to satisfy certain procedural prerequisites. Once those are met, CRA can assess you directly as a director, issue a Notice of Assessment in your name, and pursue collection against your personal assets. Your house, your savings, your investments — all of it is on the table.
Not every corporate tax debt flows through to directors. Section 227.1 covers a specific category of remittances:
Importantly, corporate income tax is not covered under section 227.1. If the corporation owes CRA for its own tax filings and cannot pay, that debt generally does not flow through to directors personally under this provision.
However, GST/HST is a separate matter. Under section 323 of the Excise Tax Act (ETA), the same concept applies to unremitted GST/HST. Directors can be personally liable if the corporation collects HST from customers and fails to remit it to CRA. The due diligence defence, limitation periods, and procedural requirements under ETA section 323 mirror those under ITA section 227.1 — same rules, different legislation. Together, these two provisions mean directors face personal exposure for both unremitted payroll deductions and unremitted sales taxes.
Before CRA can assess a director personally, it must first exhaust its remedies against the corporation itself. In practice, this means:
Once these steps are completed, CRA issues a director liability assessment. You receive a Notice of Assessment addressed to you personally for the corporate debt. From that point forward, you are a debtor to the Crown in your own right, subject to all of CRA's standard collection powers — garnishments, liens, legal action.
One critical timing rule: CRA has only two years from the date you ceased to be a director to issue the assessment. If that window closes without an assessment, you are generally protected — but the two years only begin running from when you actually and validly ceased to hold office.
A director is not liable under section 227.1 if they can demonstrate they exercised the degree of care, diligence, and skill that a reasonably prudent person would have exercised in comparable circumstances. This is the due diligence defence, and it is your primary shield — but it is not easily established.
Canadian courts distinguish between two types of directors:
An inside director is actively involved in managing the company — typically an officer-director who oversees day-to-day operations. Courts hold inside directors to a higher standard. It is not enough to claim you did not know about the remittance failures. As an inside director, you are expected to actively prevent the failure. You must ensure systems are in place, monitor payroll compliance, and intervene when remittances fall behind. Simply being unaware does not satisfy the defence if your management role gave you the ability to know and act.
An outside director is more passive — a board member who does not run the business. The standard is somewhat lower, but "I showed up to meetings and signed whatever was put in front of me" is not enough. Outside directors must still take reasonable steps to ensure remittances are being made. In practice, this means asking questions, requesting payroll reports, and following up when answers are unsatisfactory.
Whatever your role, documentation is everything. If you ever need to mount a due diligence defence, you will need to show evidence of your active oversight. This includes:
Working with an accounting firm like Swift Accounting Calgary means having a professional team that can help boards establish proper payroll oversight systems — and maintain the paper trail that supports a due diligence defence if CRA ever comes knocking.
Many directors believe that resigning from the board the moment financial trouble appears will protect them. This is a dangerous misconception. Resignation does not retroactively eliminate liability for remittance failures that occurred while you were a director.
The two-year limitation period begins from the date you ceased to be a director — but you remain liable for all remittances that should have been made up to that date. If the corporation was behind on payroll remittances for six months before you resigned, that six months of liability follows you out the door.
Equally important: the resignation must be legally valid. It must be effected by proper board resolution and, where applicable, formally filed with the applicable corporate registry. A verbal statement or informal communication that you are "stepping down" may not be sufficient to start the clock running. CRA will scrutinise the date of valid resignation carefully if a limitation period argument arises.
As noted, section 323 of the Excise Tax Act creates parallel personal liability for directors when a corporation fails to remit net GST/HST. The same mechanics apply: CRA must exhaust remedies against the corporation first, then assess directors within two years of them ceasing to hold office. The due diligence defence is also available on substantially the same terms.
The practical takeaway is that a struggling corporation that is both behind on payroll remittances and not remitting HST collections can expose its directors to assessments on two separate fronts simultaneously — payroll under the ITA and sales tax under the ETA. The combined amounts can be substantial.
The best strategy is prevention. Directors and businesses working with Swift Accounting in Calgary consistently hear the same core advice:
Lack of knowledge alone is not a complete defence, particularly for inside directors who have a management role. Courts expect directors to have systems in place to monitor payroll compliance. For outside directors, demonstrating that you took reasonable steps to inquire and were misled may support a due diligence defence, but it depends heavily on the specific facts and the evidence you can produce.
Yes. Corporate bankruptcy does not extinguish director liability under section 227.1. In fact, a bankruptcy often triggers the conditions for director assessment — the trustee's inability to satisfy the CRA debt through corporate assets satisfies CRA's obligation to exhaust remedies against the corporation. Directors are frequently assessed shortly after a corporation enters bankruptcy or receivership.
If your resignation was legally valid and more than two years have passed without CRA issuing an assessment, you are generally protected by the limitation period under section 227.1(4). However, the exact date your directorship ended matters significantly. If CRA disputes when you actually ceased to be a director — for example, because the resignation was never properly filed — the limitation period may not have started when you think it did. Legal and accounting advice is recommended before concluding you are clear.
No. Section 227.1 applies specifically to amounts the corporation was required to deduct or withhold and remit — payroll source deductions and employer CPP/EI contributions. Corporate income tax assessed on the corporation's own profits is not covered by this provision. Directors are not personally liable for unpaid corporate income tax under the ITA, though other legal theories could arise in egregious circumstances.
Directors' liability for CRA debts is one of the most serious personal financial risks in Canadian corporate governance. The rules are technical, the stakes are high, and CRA pursues these assessments with considerable resources. Whether you are a seasoned executive or a first-time board member, getting your payroll compliance and board oversight practices right from the start is far less costly than defending an assessment later.
