In 2026, directors and officers of Quebec companies are facing an increasingly demanding legal environment. The personal liability of directors is no longer a theoretical threat — it is a concrete reality that is manifested in a growing number of disputes before the civil courts of Quebec. For any civil litigation lawyer, these cases illustrate the crucial importance of rigorous governance.

The legal framework for directors’ liability in Quebec

The Quebec Business Corporations Act (QBCA) and the Canada Business Corporations Act (CBCA) impose fundamental obligations on directors: the duty of loyalty and the duty of care. The director must act honestly, in good faith and in the best interests of the corporation. He must also exercise the care, diligence and skill that a reasonable person would exercise in comparable circumstances.

The Civil Code of Québec completes this framework by imposing extra-contractual liability. Article 1457 C.C.Q. allows any person who has suffered an injury to sue a director who has committed a fault in the performance of his or her duties, even in the absence of a direct contractual relationship.

Situations that engage personal responsibility

There are several common situations that can give rise to the personal liability of a director. The first is blatant mismanagement: decisions taken without sufficient information, without consultation with experts when necessary, or in a situation of undeclared conflict of interest. Courts assess these decisions not in hindsight, but in light of what a reasonable director would have done at the time of the decision.

The second situation concerns tax and wage obligations. Under the Quebec Taxation Act and the federal Income Tax Act, directors may be held personally liable for unremitted source deductions, unpaid payroll taxes, and certain tax debts of the corporation.

The third concerns environmental and regulatory obligations. A director who turns a blind eye to non-compliant practices is exposed to personal prosecution, including criminal lawsuits.

Lifting the corporate veil: when society no longer protects

Article 317 of the Civil Code of Québec allows the courts to lift the corporate veil when the legal personality of a company is used to hide fraud or abuse of rights. In these cases, the director loses the protection offered by the corporate structure and is personally liable for the company's obligations.

The courts use this mechanism when they find a confusion of assets between the director and the company, the lack of compliance with corporate formalities, or the use of the company as a simple screen for the personal activities of the director. A dispute between shareholders can also highlight these abuses.

Protecting yourself effectively as an administrator

The best protection is prevention. A wise director ensures that his or her decisions are documented, that any conflicts of interest are declared, that professional advice is relied upon for complex decisions, and that detailed minutes of each board meeting are maintained.

Directors' and Officers' Liability Insurance (D&O Insurance) provides an additional safety net, but it does not cover intentional misconduct or fraud. A rigorous internal compliance policy is therefore essential.

Why the intervention of a lawyer is strategic

A residential construction case rarely involves a single legal issue. It often involves both a contract for work, the legal guarantee of quality, a guarantee plan such as the RCM, insurance and municipal rules. Identifying the right legal basis, the right defendant, and the right time to act is essential.

The civil lawyer intervenes at several levels: analysis and securing of the contract before signing, supervision of formal notices during the construction site, negotiation of corrective measures, and, when necessary, preparation of a legal recourse. In some cases, The use of mediation allows the conflict to be resolved more quickly than a trial, provided that the strategy is solidly prepared.

Frequently asked questions about directors’ liability

Can a director be sued personally for the company’s debts?

In principle, no, because the company is a separate legal entity. However, the courts can lift the corporate veil in the event of fraud, abuse or patrimonial confusion, which exposes the director to personal liability.

Does D&O insurance protect against all lawsuits?

No. Directors and Officers Liability Insurance has important exclusions, including intentional misconduct, fraud and certain regulatory offences. It is a safety net, but it is not a substitute for strong governance.

What are the obligations of a director towards minority shareholders?

The director must act in the best interests of the corporation as a whole, not in the exclusive interests of any group of shareholders. Minority shareholders have remedies available to them in the event of oppression or abuse, including recourse under section 450 of the QBCA.

How can we prove that a director has failed in his duty of care?

The applicant must show that the administrator did not act as a reasonable person would have done in the same circumstances. Lack of documentation, failure to consult experts and failure to comply with internal procedures are common indications used by the courts.
