Personal Liability of Directors in Canada: When the Corporate Veil Doesn’t Protect You

One of the first things every business person learns about corporations is that they provide limited liability. The corporation is a separate legal person. Its debts are its own. Shareholders risk only their investment, and directors who act on the corporation’s behalf are not personally responsible for what the corporation does. That, at least, is the starting point.

The reality is considerably more complicated. Canadian law contains a long and growing list of circumstances in which directors (and often officers) are personally liable for corporate conduct, corporate debts, and corporate failures. Some of these liabilities arise at common law, where a director’s own conduct crosses the line from corporate action into personal wrongdoing. Others are imposed by statute: unpaid wages, unremitted source deductions, unremitted HST, environmental contamination, and a surprising range of other obligations can all land personally on the people who sit on the board. A director can be diligent, honest, and unpaid for their service, and still find themselves writing a personal cheque for a corporate debt.

This article is a comprehensive overview of the personal civil liability of directors in Canada, with a focus on Ontario. It explains the common law framework that determines when a director’s conduct attracts personal tort liability, surveys the principal statutory liabilities under Ontario and federal law, explains the due diligence and other defences available, and offers practical guidance for directors who want to understand and manage their exposure. It also includes a reference chart summarizing the principal sources of personal liability in one place. It is written for directors and officers, for the shareholders and creditors who may have claims against them, and for the lawyers who advise both sides. Our officer and director liability practice regularly acts in these disputes in Ontario.

The Starting Point: The Corporate Veil

The foundation of modern corporate law is the principle that a corporation is a legal person separate from its shareholders, directors, and officers. When the corporation contracts, it is the corporation that is bound. When the corporation commits a tort through its employees, it is the corporation that is liable. Directors who cause the corporation to act are, in law, the corporation acting: their acts are its acts, and the liability is corporate, not personal.

This principle serves an important economic function. Limited liability encourages investment, risk-taking, and entrepreneurship by capping the downside. If every director faced unlimited personal exposure for every corporate misstep, qualified people would refuse to serve on boards, and the cost of corporate governance would rise dramatically.

But the principle has never been absolute. The corporate veil does not protect a director who commits a tort personally, even in the course of corporate duties. It does not protect a director against the dozens of statutes that expressly impose personal liability for specific corporate failures. And it does not protect a director against the oppression remedy, which gives courts broad jurisdiction to impose personal liability where the director’s own conduct has unfairly harmed a stakeholder. The rest of this article maps these exceptions.

Common Law Liability: When a Director’s Conduct Becomes Their Own

The General Framework

The leading Ontario authorities on when a director or officer is personally liable in tort for actions taken in a corporate capacity are the Court of Appeal’s decisions in ScotiaMcLeod Inc. v. Peoples Jewellers Ltd. and ADGA Systems International Ltd. v. Valcom Ltd. Together with the cases applying them, they establish a framework that can be summarized in a few propositions.

First, whether a director or officer will be found personally liable for actions ostensibly carried out under a corporate name is fact-specific. There is no blanket immunity and no blanket liability.

Second, absent allegations of fraud, deceit, dishonesty, or want of authority, directors and officers are protected from personal liability unless it can be shown that their actions are themselves tortious, or exhibit a separate identity or interest from that of the corporation so as to make the act or conduct complained of their own.

Third, the facts giving rise to personal liability must be specifically pleaded. A plaintiff cannot simply name the directors alongside the corporation and hope that something sticks. As the Court of Appeal held in Normart Management Ltd. v. West Hill Redevelopment Co., liability does not attach to individual officers merely because they might stand to gain financially from the impugned transactions through their positions in the corporation.

Fourth, and importantly, the protection is narrower than many directors assume. In ADGA Systems, the Court of Appeal confirmed that officers, directors, and employees of corporations are responsible for their own tortious conduct even where that conduct was directed in a bona fide manner to the best interests of the company. A director who personally commits the tort of deceit, conspiracy, or negligence is personally liable for it. Acting for the company’s benefit is not a defence to one’s own tort.

The Said v. Butt Exception: Inducing Breach of Contract

There is one significant carve-out from the principle that directors are liable for their own torts. Under the rule in the English case Said v. Butt, adopted and consistently applied in Canada, a director or employee is not liable for the tort of inducing breach of contract where the contract breached is the corporation’s own contract, provided the director acted bona fide within the scope of their authority for the protection of the corporation’s legitimate interests.

The logic is structural. A corporation can only act through human agents. If a director, acting as the corporation’s directing mind, causes the corporation to breach a contract, the director’s act is in law the corporation’s act. A company cannot induce its own breach of contract, and the director who is the company’s alter ego for that decision cannot be sued as a third-party inducer. As the Newfoundland Court of Appeal observed in Imperial Oil Ltd. v. C & G Holdings Ltd., where a director believes the company’s interests are best served by breaking a contractual commitment, the director is entitled, if not obligated, to cause the company to do so.

The exception has limits. It protects only bona fide conduct within the scope of authority directed at the corporation’s legitimate interests. A director who acts fraudulently, dishonestly, or for their own separate purposes loses the protection. And the exception applies only to the specific tort of inducing breach of the corporation’s own contract; it does not shield a director from other torts, such as deceit, conspiracy, or negligent misrepresentation.

Civil Fraud and Fraudulent Misrepresentation

No corporate office protects a director who personally engages in fraud. The Supreme Court of Canada in Bruno Appliance and Furniture, Inc. v. Hryniak set out the four elements of civil fraud: a false representation made by the defendant; some level of knowledge of the falsehood (whether actual knowledge or recklessness); the false representation caused the plaintiff to act; and the plaintiff’s actions resulted in a loss. A director who personally makes fraudulent representations, even in the course of promoting the corporation’s business, is personally liable for the consequences. Fraud is the paradigm case of conduct that is “themselves tortious” within the meaning of the ScotiaMcLeod framework.

Negligent Misrepresentation and Other Torts

Directors can also be personally liable for negligent misrepresentation where they personally make representations in circumstances that create a duty of care, for conspiracy where they combine with others to injure the plaintiff, and for breach of trust where corporate structures are used to misappropriate funds held for others. In each case, the analytical question is the same: was the impugned conduct genuinely the director’s own, or was it in substance the conduct of the corporation? Where the director’s involvement is personal, deliberate, and tortious, the corporate veil offers no protection.

No General Duty to Strangers

The framework has an outer boundary. In Piedra v. Copper Mesa Mining Corporation, the Ontario Court of Appeal held that a corporate director has no established duty in law to be mindful of the interests of strangers to the corporation when discharging their duties as a director. Plaintiffs who sued two non-management directors of a mining parent company for harms allegedly inflicted by the security personnel of a foreign subsidiary could not establish a recognized duty of care, and the court declined to recognize a novel one. Directors’ common law exposure, in other words, generally arises from what they personally do, not from a free-standing obligation to police everything the corporate group touches.

Statutory Liability: The Ontario Statutes

The common law framework is only half the picture. The more frequent source of personal director liability in practice is statute. Legislatures, both provincial and federal, have repeatedly decided that certain corporate obligations are important enough that the people controlling the corporation should personally guarantee their performance.

Unpaid Wages: OBCA Section 131

Under section 131 of Ontario’s Business Corporations Act, the directors of a corporation are jointly and severally liable to the employees of the corporation for all debts not exceeding six months’ wages that become payable while they are directors for services performed for the corporation, and for vacation pay accrued while they are directors.

The liability is subject to important preconditions. The director is liable only if the corporation is sued for the debt within six months after it becomes due and execution against the corporation is returned unsatisfied in whole or in part, or if the corporation enters liquidation, dissolution, or bankruptcy proceedings and a claim for the debt is proved within six months. An action against a director must be brought within six months after they cease to be a director. The courts have characterized the action against a director for wages as an action on a debt, and the statutory preconditions are strictly applied.

The policy rationale is straightforward: employees are involuntary and vulnerable creditors who cannot diversify their exposure to their employer’s insolvency the way commercial lenders can. The personal liability of directors for a capped amount of wages is a statutory exception to the corporate veil designed to protect them. The federal Canada Business Corporations Act contains a parallel provision in section 119.

Employment Standards Act, 2000

Ontario’s Employment Standards Act, 2000 contains its own director liability regime in Part XX. Directors are jointly and severally liable for up to six months’ unpaid wages and up to twelve months’ accrued vacation pay, where the statutory triggering conditions are met (insolvency of the employer with a filed claim, or unpaid orders of an employment standards officer or the Ontario Labour Relations Board).

Two features of the ESA regime deserve emphasis. First, the liability excludes termination pay and severance pay, which significantly limits the exposure compared to what employees often expect. Second, the Act expressly provides that no contract, by-law, or resolution can relieve a director from the duty to act according to the Act or from liability for breaching it, though the employer may indemnify directors who acted honestly and in good faith.

Environmental Statutes

Ontario’s Environmental Protection Act and Ontario Water Resources Act impose duties on directors and officers to take all reasonable care to prevent the corporation from causing or permitting unlawful discharges of contaminants. Directors can be personally named in administrative orders, including remediation orders, and can face personal liability for environmental harm where they failed to exercise the required oversight. Environmental liability is among the most significant personal exposures for directors of corporations that own land or operate industrial facilities, because remediation costs can dwarf the corporation’s assets and the orders can follow directors personally even after the corporation is gone.

Other Ontario Statutes

The pattern repeats across the Ontario statute book. The Condominium Act, 1998 imposes duties and potential personal liability on condominium directors. The Securities Act imposes personal liability on directors for misrepresentations in prospectuses and continuous disclosure documents, and for insider trading. The Tobacco Tax Act, the Pesticides Act, the Credit Unions and Caisses Populaires Act, and the Cooperative Corporations Act all contain director liability provisions tailored to their subject matter. A director of any regulated business should assume that the regulatory statute governing that business contains personal liability provisions and should find out what they are.

Statutory Liability: The Federal Statutes

Unremitted Source Deductions: Income Tax Act Section 227.1

The most frequently litigated director liability provision in Canada is section 227.1 of the federal Income Tax Act. When a corporation deducts income tax, CPP contributions, and EI premiums from its employees’ pay, it holds those amounts for the Crown. If the corporation fails to remit them, the directors at the time of the failure are jointly and severally liable, together with the corporation, for the unremitted amounts plus interest and penalties.

The structure of section 227.1 deserves close attention because it recurs throughout federal law. The Canada Revenue Agency cannot simply assess a director directly. Liability is subject to preconditions: a certificate for the corporation’s liability must be registered in the Federal Court and execution returned unsatisfied in whole or in part, or the corporation must have entered liquidation, dissolution, or bankruptcy proceedings with the Crown’s claim proved within the prescribed six-month window. A director cannot be assessed more than two years after they last ceased to be a director, which makes the documentation of resignation dates critically important. A director who pays is entitled to contribution from the other directors who were liable.

The same architecture appears in section 323 of the Excise Tax Act, which imposes parallel personal liability on directors for the corporation’s unremitted GST/HST. For many small and medium-sized business directors, unremitted HST is the single largest personal exposure they carry, often without realizing it.

The Due Diligence Defence and Buckingham

Both section 227.1(3) of the Income Tax Act and section 323(3) of the Excise Tax Act provide a defence: a director is not liable where they exercised the degree of care, diligence and skill to prevent the failure that a reasonably prudent person would have exercised in comparable circumstances.

The leading authority on this defence is the Federal Court of Appeal’s decision in Buckingham v. Canada. Two holdings from Buckingham define the modern law. First, the standard is objective. It does not vary with the director’s personal skills, knowledge, abilities, and capacities. A director cannot defend on the basis that they were inexperienced, financially unsophisticated, or passive. The objective standard puts pressure on corporations to improve governance and discourages the appointment of inactive directors chosen for show; a person who accepts a directorship must carry out the duties of that office on an active basis and cannot rely on their own inaction.

Second, the focus of the defence is prevention, not cure. The director must establish that they were specifically concerned with the tax remittances and exercised their duty of care with a view to preventing the failure to remit. A director who learns of a remittance failure and works diligently afterward to fix it has not made out the defence if they took no steps to prevent the failure in the first place. Most importantly, a director cannot make out the defence where they condone the continued operation of the corporation by diverting employee source deductions to other purposes, such as paying suppliers or keeping the business afloat in the hope of better days. Source deductions are the Crown’s money. Using them as working capital transfers the risk of the business to the Crown, and that is precisely the mischief the section is designed to prevent.

The case law does, however, recognize real limits. Courts have exonerated directors who lacked the authority to make the remittances themselves but actively alerted the board to the liabilities, proposed concrete cost-cutting measures, and took every step available within their actual power. The defence is demanding but not impossible, and the outcome turns on documented, contemporaneous, preventive action.

Inside and Outside Directors

While the standard is objective, the circumstances of the director are part of the “comparable circumstances” against which the reasonably prudent person is measured. The jurisprudence distinguishes between inside directors, who are involved in day-to-day management and have direct access to financial information, and outside directors, who are not. More is expected of an inside director, who is presumed to know the corporation’s remittance position, than of an outside director who reasonably relied on management until put on notice of a problem. But the distinction is one of application, not principle, and an outside director who learns of remittance problems and does nothing cannot shelter behind their outside status. The duty is to act on what a reasonably prudent person would have done in those circumstances.

It is also worth noting that liability attaches to those who are directors in law or in fact. A person who has resigned in writing and ceased to act has a clean two-year clock. A person who resigns on paper but continues to manage the corporation may be treated as a de facto director and remain exposed.

Other Federal Statutes

The federal pattern parallels the provincial one. The Canada Business Corporations Act imposes liability for wages (section 119) and for improper distributions. The Bankruptcy and Insolvency Act contains provisions allowing the review of transactions and the recovery of dividends and other distributions made while the corporation was insolvent. The Competition Act, the Canadian Environmental Protection Act, 1999, the Employment Insurance Act, the Bank Act, and the Trust and Loan Companies Act all contain director liability or director duty provisions applicable to corporations within their scope.

The Oppression Remedy: Personal Liability in Equity’s Clothing

Beyond tort and statute, directors face a third source of personal exposure: the oppression remedy under section 248 of the OBCA and section 241 of the CBCA. The oppression remedy gives the court broad, equitable jurisdiction to rectify conduct that is oppressive, unfairly prejudicial to, or that unfairly disregards the interests of a shareholder, creditor, director, or officer.

The Supreme Court of Canada’s framework treats oppression as an equitable remedy concerned with fairness and business realities, not merely narrow legalities. The complainant must identify the reasonable expectations they claim were violated and demonstrate that those expectations were undermined by conduct that was oppressive, unfairly prejudicial, or unfairly disregarding of their interests.

Critically for present purposes, the remedy can be granted against directors personally. The case law establishes that to impose personal liability on a director, there must be oppressive conduct that is properly attributable to the individual’s involvement in the oppression, and personal liability must be a fit remedy in the circumstances. Directors who strip assets from a corporation facing a creditor’s claim, who divert corporate funds to themselves or related parties, who prefer their own interests in a corporate restructuring, or who use corporate structures to defeat the reasonable expectations of stakeholders, can be ordered personally to compensate the complainant.

The courts have also marked the remedy’s limits. The oppression remedy protects the complainant’s interests as a corporate stakeholder, and the relief must be aimed strictly at rectifying the oppression; as one court memorably put it, the remedial powers should be exercised with a scalpel rather than a battle axe. A plaintiff whose only status as a creditor was created by the very conduct complained of cannot use the remedy as a substitute for an ordinary breach of contract or tort claim, and the remedy is not a shortcut to judgment or de facto execution before judgment against a corporate defendant.

Reference Chart: Principal Sources of Director Personal Liability

The following chart summarizes the principal sources of personal civil liability for directors of Ontario corporations, the trigger for each, the scope of the exposure, and the principal defences or limits.

Managing the Exposure: Practical Guidance for Directors

The breadth of potential liability does not mean that serving as a director is reckless. It means that the role should be approached with informed discipline. Several practical measures substantially reduce the exposure.

First, stay actively informed about remittances. The largest and most common personal liabilities (source deductions and HST) are entirely preventable through monitoring. Directors should require regular confirmation, at every board meeting, that payroll remittances and HST are current, and should treat any deferral of remittances as a red flag demanding immediate action. The Buckingham standard rewards documented, preventive vigilance and punishes passivity.

Second, document everything. The due diligence defences across the statutory landscape turn on what the director actually did, and contemporaneous records are the evidence. Board minutes recording questions asked about remittances, emails raising concerns, written proposals for corrective measures, and records of reliance on professional advice are the raw material of a successful defence.

Third, understand the resignation rules. The two-year limitation period under section 227.1(4) of the Income Tax Act runs from when the director last ceased to be a director. A director of a financially troubled corporation who decides the risks have become unacceptable should resign formally, in writing, with the resignation properly recorded in the corporate registers, and should genuinely cease to act. A paper resignation followed by continued de facto management does not stop the clock.

Fourth, secure indemnification and insurance. Corporate indemnification agreements and directors’ and officers’ (D&O) liability insurance are the standard tools for managing residual exposure. Directors should understand what their indemnity covers, what the D&O policy excludes (statutory remittance liabilities and fraud are commonly excluded or limited), and whether the policy includes coverage that survives the corporation’s insolvency, which is precisely when it is most needed.

Fifth, take pleadings against you seriously, but insist on proper pleading. The ScotiaMcLeod line of cases requires plaintiffs to plead the specific facts said to give rise to personal liability. Claims that simply name directors alongside the corporation without alleging conduct that is personally tortious or a separate identity of interest are vulnerable to being struck, and an early pleadings motion can end the personal claim before it generates years of exposure and cost.

Conclusion

Limited liability is the starting point of corporate law, not the end of the analysis. Directors of Canadian corporations face personal civil liability from three directions: the common law, where their own conduct is tortious or exhibits a separate identity from the corporation’s; statute, where legislatures have made directors the personal guarantors of wages, tax remittances, environmental compliance, and a long list of other corporate obligations; and the oppression remedy, where equity reaches directors whose personal conduct has unfairly harmed corporate stakeholders.

The unifying theme across all three is that the law rewards engaged, informed, documented diligence and punishes passivity. The director who monitors remittances, asks questions, documents the answers, acts on red flags, and resigns formally when the situation becomes untenable has powerful defences across the entire liability landscape. The director who treats the role as honorary, signs what is put in front of them, and assumes the corporate veil will protect them is the director who ends up personally liable. For anyone who sits on a board, or is considering joining one, understanding this landscape is not optional. It is the job.
