Director’s Liability: Taxes Directors Can Be Personally On the Hook For – A Complete Guide by a Montreal CPA Firm Near You

Many Canadians accept directorships in corporations without fully understanding that
directors can be held personally liable for certain tax debts of the corporation. When a
business fails, becomes insolvent, or falls behind on government remittances, CRA has
the legal authority to pursue directors personally—even years after the corporation has
ceased operations. The most common exposures include unremitted payroll source
deductions (CPP, EI, income tax) and unremitted GST/HST or QST. If CRA determines
that a director did not exercise the proper standard of care, diligence, and skill, it may
assess the director personally for these amounts, plus penalties and interest.
Understanding director liability in Canada is essential for anyone acting as a
director—shareholders, family members, spouses, investors, and silent
partners—because ignorance of the rules does not protect against CRA assessments.
Legal and Regulatory Framework
Director liability arises from specific provisions in Canadian tax legislation:
• Income Tax Act (ITA), Section 227.1 – makes directors personally liable for
unremitted payroll source deductions, including income tax, CPP, and EI withheld
from employees.
• Excise Tax Act (ETA), Section 323 – makes directors personally liable for
unremitted GST/HST.
• Tax Administration Act (Québec) – imposes similar obligations for QST and Québec
source deductions.
• Two-Year Rule – CRA can only assess directors within two years after they cease
being directors, but this clock may restart if they are reinstated.
• Due Diligence Defence – directors can avoid liability if they prove they exercised the
level of care, diligence, and skill that a reasonably prudent person would have exercised
in comparable circumstances.
• Corporate Dissolution does not erase liability; CRA can assess directors if
remittances were outstanding at dissolution.
Director liability applies to de jure directors (legally appointed) and, in some cases, de
facto directors—those who act like directors even without formal appointment.
These rules form the statutory framework for director liability in Canada.
Key Court Decisions
Several important court rulings illustrate how courts interpret director liability:
In Buckingham v. Canada, the Federal Court of Appeal ruled that directors must be
active participants in overseeing remittances, not passive observers. The due diligence
defence requires proactive involvement.
In Balthazar v. Canada, the court confirmed that CRA can pursue directors even years
later, provided the claim falls within the two-year period after resignation.
In Soper v. Canada, the court held that ignorance is not a defence; directors must
inform themselves of the corporation’s financial affairs and ensure remittances are
made promptly.
In Worrell v. Canada, a director was found personally liable because he relied entirely
on the corporation’s accountant and did not verify remittance compliance.
These cases demonstrate that CRA and the courts hold directors to a high standard of
accountability.
Why CRA Targets This Issue
CRA aggressively enforces director liability because payroll and GST/HST remittances
are trust funds, meaning the corporation holds these amounts on behalf of employees
and the government. CRA focuses on:
• companies with unpaid payroll remittances
• corporations that owe GST/HST or QST when they shut down
• directors who resign during a financial collapse
• corporations that repeatedly file late remittances
• situations where directors withdraw funds while remittances remain unpaid
• dissolved corporations with outstanding assessments
CRA’s Director Liability Program routinely traces director appointments, minute books,
provincial corporate registry filings, and financial records to build liability cases.
Because these debts often reach into the tens or hundreds of thousands, CRA uses
director liability rules as a key enforcement tool.
Mackisen Strategy
At Mackisen CPA Montreal, we help directors protect themselves from personal tax
exposure by implementing compliance systems and, when necessary, defending
against CRA director liability assessments. Our strategy includes:
• reviewing payroll remittance history, GST/QST filings, and trust accounts
• identifying unpaid or late remittances and establishing immediate corrective action
• implementing internal controls to ensure timely payroll and GST/QST compliance
• advising directors on their legal duties and due diligence obligations
• preparing resignation documentation when appropriate to trigger the two-year
limitation period
• defending directors against assessments by demonstrating due diligence
• negotiating payment arrangements when corporations face cash flow challenges
• conducting risk reviews for new directors before accepting a board position
Our method ensures directors minimize exposure and maintain strong protection
against CRA enforcement.
Real Client Experience
A director of a struggling restaurant chain was assessed over $180,000 in unpaid
payroll taxes after the corporation closed. Although he relied on the bookkeeper, CRA
argued he failed to exercise diligence. We reconstructed timelines, proved his efforts to
correct filings, and negotiated a reduced assessment.
Another client served as a director “in name only” for a family business. CRA pursued
her personally for unremitted GST/QST. We demonstrated she was not a de facto
director and lacked control over operations. CRA withdrew the claim.
A third client resigned from a failing company but did not document the resignation
formally. CRA assessed him because he remained listed on the corporate registry. We
corrected registry records and argued the two-year limitation had expired, successfully
eliminating liability.
These cases show how proactive planning and documentation are essential for
managing director liability in Canada.
Common Questions
Directors often ask whether they can be liable even if they were not involved in
finances. Yes—courts expect directors to actively supervise remittances.
Others ask whether an accountant’s mistake protects them. No—delegation does not
eliminate liability.
Some ask whether resigning protects them immediately. The two-year clock starts only
after official resignation is properly recorded.
Another question: Can multiple directors be pursued? Yes—CRA can assess any or all
directors jointly and severally.
These questions highlight why understanding director liability in Canada is critical before
accepting or maintaining a directorship.
