Directors’ and Officers’ Liability in Ontario: Duties, Risks and How to Protect Yourself

Date: June 10, 2026

Accepting a directorship or officer role in an Ontario corporation carries genuine personal legal risk that the corporate structure does not fully eliminate. The fiduciary duties and duty of care imposed by the Ontario Business Corporations Act and the Canada Business Corporations Act create personal obligations that can result in personal liability for directors and officers who breach them, regardless of whether the corporation itself faces any consequence.

This article explains what those duties are, where personal liability most commonly arises, what recent case law confirms about the scope of directors' exposure, and what practical steps reduce the risk. For an overview of how Achkar Law handles these matters, see our directors and officers liability practice page.

The core principle
Incorporation limits personal liability for corporate obligations, but it does not eliminate personal liability for a director's own conduct. Directors who breach their fiduciary duty or duty of care, who fail to ensure statutory obligations are met, or who engage in fraudulent or tortious conduct can be held personally liable.

The corporate shield protects directors from the corporation's debts in most circumstances. It does not protect directors from their own wrongdoing. The distinction between liability for the corporation's obligations and liability for the director's personal conduct is the line that matters most in directors' liability analysis.

The duties directors and officers owe in Ontario

Directors and officers of Ontario corporations owe two primary duties codified in section 134 of the Ontario Business Corporations Act and section 122 of the Canada Business Corporations Act.

The fiduciary duty requires directors and officers to act honestly and in good faith with a view to the best interests of the corporation. This means prioritizing the corporation's interests over personal interests, avoiding undisclosed conflicts of interest, not using corporate information or opportunities for personal gain, and acting with loyalty to the corporation rather than to any particular group of shareholders or stakeholders.

The duty of care requires directors and officers to exercise the care, diligence, and skill that a reasonably prudent person would exercise in comparable circumstances. This is an objective standard: it does not require perfection or guarantee that every decision will be correct, but it requires directors to inform themselves adequately before making decisions, to monitor the corporation's affairs on an ongoing basis, and to take reasonable steps to ensure compliance with applicable law.

The business judgment rule protects directors from personal liability for honest business decisions made in good faith on a reasonable basis, even if those decisions turn out to be wrong. Courts defer to directors who informed themselves adequately, acted in the best interests of the corporation, and had no undisclosed conflict of interest. The rule does not protect decisions made in bad faith, without adequate information, or in the director's own interest at the corporation's expense.

Where personal liability most commonly arises

Unpaid wages and vacation pay Section 131 of the OBCA imposes joint and several personal liability on directors for up to six months of unpaid wages and twelve months of unpaid vacation pay where the corporation has failed to pay employees. This statutory liability is particularly significant where corporations face financial difficulty. It applies regardless of the director's knowledge of or involvement in the specific payroll failure.
Unremitted source deductions Directors of corporations that fail to remit employee income tax deductions, CPP contributions, and EI premiums to the Canada Revenue Agency can be held personally liable for those amounts plus interest and penalties under the Income Tax Act and the Excise Tax Act. A due diligence defence is available but requires demonstrating that the director took concrete steps to prevent the failure.
Securities violations Directors of reporting issuers can be held personally liable for misleading disclosure, insider trading, and other securities violations under the Securities Act and related legislation. Personal liability can arise even without direct personal gain from the violation, as confirmed by the Supreme Court of Canada in Sharp v. Autorité des marchés financiers, 2024 SCC 15.
Environmental liability Directors of corporations that cause environmental contamination can face personal liability under provincial and federal environmental legislation where the director directed, authorized, assented to, or acquiesced in the conduct that led to the violation. Environmental liability is one of the areas where director personal exposure can be most severe.
Breach of fiduciary duty Directors who use their position to benefit themselves at the corporation's expense, who take corporate opportunities for personal gain, or who act in the interests of one group of shareholders against the corporation's broader interests can face personal liability for breach of fiduciary duty under both corporate statutes and common law.
Misrepresentation in commercial transactions Directors and officers who make false or misleading statements in the course of commercial transactions, whether in financial disclosures, representations to lenders, or statements to contracting parties, can face personal liability for misrepresentation even where the corporation is the primary contracting party.

What recent case law confirms

Sharp v. Autorité des marchés financiers, 2024 SCC 15

The Supreme Court of Canada confirmed that directors can be personally liable for securities violations even without direct personal gain from the contravention. The Court emphasized that directors must take active responsibility for ensuring accurate and complete public disclosure. Passive involvement or reliance on management's representations is not a complete answer where the director had the ability and the obligation to oversee the accuracy of disclosures. The decision is a direct statement from Canada's highest court that director liability in the securities context is real and enforceable.

Abbasbayli v. Fiera Foods Company, 2021 ONCA 95

The Ontario Court of Appeal held directors personally liable for unpaid wages and vacation pay under section 131 of the OBCA. The case is a significant illustration of the wage liability provision in operation: directors cannot insulate themselves from this specific form of personal liability by pointing to their limited involvement in day-to-day payroll decisions. The statutory obligation exists independently of the director's awareness or participation in the failure to pay. For corporations in financial difficulty, this decision is a direct warning to directors who may be tempted to defer employee payments while managing cash flow pressures.

Solar Power Network Inc. v. ClearFlow Energy Finance Corp., 2019 ONCA 358

The Ontario Court of Appeal cautioned that directors and officers who exceed their authority or make misleading representations in commercial transactions can face personal liability for those misrepresentations even where the corporation is the contracting party. The decision reinforces that the corporate structure does not shield directors from the personal consequences of their own fraudulent or negligent misrepresentations made in the course of commercial dealings.

How directors and officers can protect themselves

Strengthen governance practices

Keep detailed records of board meetings, resolutions, and the information considered before major decisions. Adopt and follow conflict-of-interest policies. Ensure independent review of significant transactions. Courts assessing director conduct look at the process directors followed as much as the outcome they reached: documented deliberation and informed decision-making are the foundation of a business judgment rule defence.

Monitor statutory compliance obligations

Directors cannot delegate their obligation to ensure that statutory compliance is maintained. This includes payroll obligations, source deduction remittances, environmental compliance, and regulatory filings. Where directors rely on management to handle these obligations, they need systems in place to verify compliance rather than simply assuming it is occurring. The due diligence defence to statutory liability requires demonstrating concrete preventive steps, not mere reliance on others.

Obtain adequate D&O insurance

Directors' and officers' insurance covers defence costs and adverse judgments arising from claims against directors and officers for alleged wrongful acts in their corporate roles. It does not cover fraudulent or criminal conduct, but it is essential protection for the broad range of claims that arise from honest decisions that are later challenged. D&O insurance should be reviewed annually to ensure coverage levels remain adequate for the corporation's size and risk profile.

Manage conflicts of interest proactively

Directors must disclose conflicts of interest and absent themselves from decisions where a conflict exists. This includes transactions between the corporation and entities in which the director has an interest, decisions that benefit one group of shareholders disproportionately, and situations where the director's personal financial interests diverge from the corporation's. Undisclosed conflicts that affect corporate decisions are one of the most common sources of director liability claims.

Seek legal advice early in disputes

Director liability risks increase significantly once a dispute or regulatory investigation is underway. Early legal advice on the scope of the director's exposure, available defences, and the steps that can be taken to limit further liability is consistently more cost-effective than advice sought after proceedings have been commenced. Directors facing shareholder challenges, regulatory inquiries, or employee claims should obtain independent legal advice rather than relying on corporate counsel whose primary obligation is to the corporation.

Understand resignation rights and timing

Directors who are concerned about the direction of a corporation's management or its compliance with statutory obligations have the right to resign. But resignation alone does not eliminate all past liability: statutory liabilities such as wage claims and source deduction obligations that accrued during the period of directorship remain. The timing of resignation relative to specific events can affect the scope of personal exposure, and legal advice on resignation strategy can be important where a corporation is in difficulty.

Serving as a director or officer in Ontario and want to understand your personal legal exposure?

Director and officer liability is most effectively managed before a dispute arises. A proactive review of your obligations, governance practices, and insurance coverage costs far less than defending a personal claim.

Frequently asked questions

What duties do directors owe under Ontario law?

Directors owe two primary duties under section 134 of the Ontario Business Corporations Act and section 122 of the Canada Business Corporations Act: a fiduciary duty to act honestly and in good faith in the best interests of the corporation, and a duty of care to exercise the diligence, care, and skill that a reasonably prudent person would exercise in comparable circumstances.

Can a director be personally liable for a corporation's debts in Ontario?

Generally no, because incorporation provides a liability shield for corporate debts. However, directors can be held personally liable for unpaid wages and vacation pay under section 131 of the OBCA, unremitted source deductions under the Income Tax Act, environmental liabilities where the director authorized or acquiesced in the violation, personal guarantees given by the director, and the director's own fraudulent or tortious conduct.

What is the business judgment rule in Ontario?

The business judgment rule protects directors from personal liability for honest business decisions made in good faith on a reasonable basis, even if those decisions turn out to be wrong. Courts defer to directors who informed themselves adequately, acted in the best interests of the corporation, and had no undisclosed conflict of interest. The rule does not protect bad faith decisions, decisions made without adequate information, or decisions made in the director's personal interest.

Are directors personally liable for unpaid employee wages in Ontario?

Yes. Under section 131 of the Ontario Business Corporations Act, directors are jointly and severally liable for up to six months of unpaid wages and twelve months of unpaid vacation pay where the corporation has failed to pay employees. This liability applies regardless of the director's direct involvement in the payroll decision and is particularly significant where corporations face financial difficulty, as confirmed in Abbasbayli v. Fiera Foods Company, 2021 ONCA 95.

What is D&O insurance and do directors need it?

Directors' and officers' insurance covers directors and officers against claims arising from alleged wrongful acts in their corporate roles, including defence costs, settlements, and judgments. It does not cover fraudulent or criminal conduct. D&O insurance is not legally required but is strongly advisable for directors of any corporation of meaningful size or complexity. Without it, directors facing claims must fund their defence and any adverse judgment from personal assets.
