- Piercing the Corporate Veil: While incorporating generally shields shareholders from personal debts, the CRA possesses sweeping statutory authority under Section 227.1 of the Income Tax Act and Section 323 of the Excise Tax Act to pierce the corporate veil and hold corporate directors personally liable for 100% of unpaid payroll source deductions (CPP/EI) and unremitted GST/HST.
- The Strict Due Diligence Standard: Directors can escape personal liability only by proving they exercised the degree of care, diligence, and skill that a reasonably prudent person would have exercised in comparable circumstances to prevent the failure to remit.
- The Absolute Two-Year Limitation Shield: Under Subsection 227.1(4), the CRA is permanently statute-barred from assessing a former director unless formal assessment proceedings commence within exactly two years after the individual ceased to be a director of the corporation.
When a Canadian business faces insolvency, cash-flow emergencies, or creditor pressure, corporate leadership often makes the desperate decision to triage payments: paying critical suppliers and payroll while delaying remittances to the Canada Revenue Agency. Directors rationalize this choice under the assumption that the limited liability structure of the corporation will insulate their personal family assets if the company fails.
This assumption is a catastrophic legal fallacy. Under Canadian tax jurisprudence, funds collected for GST/HST and employee payroll deductions (CPP, EI, income tax withholdings) are legally classified as deemed trust funds held in trust for the Crown. When a corporation fails to remit these trust amounts, the CRA can bypass bankruptcy proceedings and pursue directors’ personal homes, bank accounts, and investments.

Director Liability Matrix: Trust Debt vs. General Corporate Income Tax
The comparative breakdown below distinguishes which corporate tax debts trigger personal director liability versus those insulated by corporate bankruptcy:
| Corporate Tax Category | Personal Director Liability? | Statutory Provision | Corporate Bankruptcy Protection |
|---|---|---|---|
| Payroll Source Deductions (CPP/EI) | 100% Personal Liability | ITA Section 227.1(1) | None (CRA assesses director personally) |
| Unremitted GST / HST Collections | 100% Personal Liability | ETA Section 323(1) | None (CRA assesses director personally) |
| Corporate Income Tax (T2 Balance) | No Personal Liability | General Corporate Debt | Extinguished upon corporate bankruptcy discharge |
| Provincial Sales Tax (PST/RST) | Personal Liability (BC, SK, MB, QC) | Provincial Revenue Statutes | None (Provincial ministries assess director) |
The Two Core Defenses Against CRA Director Assessments
If the CRA issues a formal Proposal to Assess Director Liability, two primary legal shields exist:
1. The Due Diligence Defense
Under Section 227.1(3) and Section 323(3), a director is not liable if they exercised reasonable diligence to prevent the failure. Following the leading Federal Court of Appeal decision in Buckingham v. The Queen, establishing due diligence requires proving proactive, preventative conduct:
- Active Oversight: Demonstrating that the director established dedicated trust bank accounts for GST/HST collections and mandated regular verification reports from the accounting department.
- Outside Influence Resistance: Passively relying on a co-director or CFO who promised “taxes were being handled” is legally classified as wilful blindness, not due diligence.
2. The Two-Year Statute of Limitations Defense
The most absolute defense is the two-year limitation rule. The CRA cannot assess a director if more than two years have elapsed since the individual officially ceased to hold office. However, establishing this defense requires formal corporate legal documentation:
- Formal Written Resignation: Execute a written resignation delivered to the corporation’s registered office.
- Provincial/Federal Registry Update: File a Notice of Change with Corporations Canada or the provincial corporate registry. If your name remains on the public registry, courts treat you as a de facto director, invalidating the limitation clock.

People Also Ask
Can the CRA seize a director’s house for corporate tax debt?
Yes. Once the CRA assesses a director personally under Section 227.1 or Section 323, the debt becomes a personal tax liability. The CRA can register a memorial or lien against the director’s personal real estate, freeze bank accounts, and seize personal investments.
Are passive or non-active directors protected from CRA liability?
No. Canadian courts have repeatedly ruled that “silent directors” or family members appointed as nominal directors (such as a spouse) are held to the exact same objective standard of diligence as managing executive directors.
Does corporate bankruptcy protect directors from Section 227 liability?
No. While corporate bankruptcy discharges general commercial vendor debts and corporate income tax (T2), it does not extinguish statutory trust liabilities. In fact, corporate bankruptcy often accelerates the CRA’s assessment of directors personally.
How can a resigning director prove the 2-year limitation period?
By producing a dated, written resignation letter delivered to the corporation, along with the stamped Notice of Change filed with the provincial or federal corporate registry confirming the exact date of cessation.
