Ontario Director Liability Guide 2024

The Dual Nature of Director Obligations in Ontario

Ontario directors face liability from two distinct sources: corporate law duties under the Ontario Business Corporations Act (OBCA) — fiduciary duty, duty of care, and the business judgment rule — and statutory liability for specific corporate obligations (wages, source deductions, HST, environmental obligations). Understanding both is essential for advising directors, structuring governance, and managing director exposure.

Fiduciary Duty Under OBCA s.134

Section 134(1) of the OBCA imposes two core obligations on every director and officer:

• (a) Fiduciary duty: Act honestly and in good faith with a view to the best interests of the corporation
• (b) Duty of care: Exercise the care, diligence, and skill that a reasonably prudent person would exercise in comparable circumstances

To Whom is the Duty Owed?

The Supreme Court of Canada confirmed in BCE Inc v 1976 Debentureholders [2008] 3 SCR 560 that directors owe their fiduciary duty to the corporation, not to individual shareholders, creditors, or other stakeholders. However, BCE also recognized that directors may consider the interests of stakeholders — employees, creditors, the community — when determining what is in the corporation's best interests. This is not a licence for directors to subordinate shareholders' interests to stakeholders but rather recognition that the corporation has a broader constituency whose interests may be relevant to long-term value.

For publicly traded corporations, the Peoples v Wise [2004] SCC framework confirmed that directors do not owe fiduciary duties to creditors directly — though directors must consider the corporation's obligations to creditors as part of what constitutes the corporation's best interests, particularly in distress situations.

Conflicts of Interest: OBCA s.132

OBCA s.132 governs director conflicts of interest. A director who is a party to, or has a material interest in a party to, a material contract or proposed material contract with the corporation must:

1. Disclose in writing the nature and extent of the interest at the time the matter is first considered at a board meeting
2. Refrain from voting on any board resolution to approve the contract, unless the contract is with an affiliate or the interested director is a director of an affiliated corporation

Contracts approved in compliance with s.132 (full disclosure, no vote by interested director) are not voidable by the corporation solely because of the director's interest — the contract stands on its merits. Contracts concluded in breach of s.132 may be set aside by the corporation or a court.

The Business Judgment Rule

The business judgment rule protects directors from liability for honest business decisions made on an informed basis, in good faith, without conflicts, within the range of reasonable business choices. Ontario courts derived the doctrine from Delaware law but adapted it for the Canadian context.

The rule does not protect:

• Decisions made in bad faith or with an improper purpose
• Decisions involving undisclosed conflicts of interest
• Decisions where the directors were not reasonably informed
• Decisions that are completely irrational or impossible to justify on any business grounds

Informed decision-making: Directors are not expected to be experts in every field. They may rely on expert advice — financial, legal, scientific — and are protected when they do so reasonably. OBCA s.135 provides a statutory due diligence defence: a director is not liable if they rely in good faith on financial statements represented by a financial officer or auditor, or on a report of a professional adviser.

Duty of Care: The Reasonable Director Standard

The duty of care in OBCA s.134(1)(b) is objective — the standard of a reasonably prudent person in comparable circumstances. This is not a demanding standard; courts recognize that business decisions involve uncertainty and risk. Directors are not guarantors of the corporation's success.

Key elements of the duty of care:

• Attendance and engagement: Directors must actually attend board meetings and engage with material issues — absentee directors who rubber-stamp management decisions may face liability
• Information and inquiry: Directors must seek adequate information before making decisions — asking questions, reviewing financial statements, obtaining expert advice where appropriate
• Supervision: Directors must exercise reasonable supervision over management — delegating is permissible but not abdicating
• Dissent: OBCA s.135(3) allows a director to protect themselves by entering a dissent to a board resolution in the minutes — a director who dissents in writing is not liable for the board's decision

Statutory Liability for Wages Under OBCA s.131

One of the most significant personal liability risks for Ontario directors is the statutory obligation for unpaid employee wages. OBCA s.131 provides:

• Directors are jointly and severally liable for up to 6 months of unpaid wages that became due while they were directors
• Directors are also jointly and severally liable for up to 12 months of unpaid vacation pay
• This is separate from termination pay and severance pay — those are claims against the corporation under the Employment Standards Act, not statutory director liability

Enforcement: The Employment Standards Act also creates director liability for unpaid wages (ESA s.81) — a parallel regime. The ESA route does not require a prior judgment against the corporation and can be more efficient for employees recovering wages from an insolvent corporation.

Due diligence defence: A director can avoid OBCA s.131 liability by establishing that they exercised the care, diligence, and skill that a reasonably prudent person would have exercised to prevent the failure to pay wages. This typically requires showing the director took positive steps — monitoring the corporation's financial position, implementing payroll controls, raising concerns with management — not merely that they were unaware of the problem.

Tax Remittance Liability: CRA Director Assessments

Directors face significant personal liability for corporate tax failures under federal legislation:

Income Tax Act s.227.1 — Source Deduction Liability

Directors are jointly and severally liable with the corporation for the corporation's failure to remit employee source deductions (income tax, CPP, EI withheld from employees). The CRA must prove: the corporation failed to remit; the director was a director at the time; and the director failed to exercise due diligence.

Excise Tax Act s.323 — GST/HST Liability

Directors are personally liable for the corporation's failure to collect and remit HST/GST. The same due diligence defence applies. HST director assessments are common in corporate insolvency situations — the CRA routinely assesses directors for unpaid HST in failed businesses.

Two-Year Assessment Limitation

Under both ITA s.227.1 and ETA s.323, the CRA must assess a director within 2 years of the director's resignation or ceasing to be a director. Proper and timely resignation — with a filed resignation notice and updated corporate records — starts the 2-year clock. De facto directors (people exercising director functions without formal appointment) may be assessed as directors even without a formal resignation.

Due Diligence Defence for Tax Remittances

The due diligence defence for tax remittances was analyzed in Soper v Canada [1997] and subsequent cases. Key factors courts consider: whether the director was actively involved in managing the corporation or an arm's-length outside director; whether the director was aware of cash flow problems; what steps the director took to ensure remittances were made; and whether the director took steps to correct the situation when problems became known. Inside directors with financial management oversight face a higher standard than outside directors without operational involvement.

Environmental Liability for Directors

Under Ontario's Environmental Protection Act (EPA) and the federal Fisheries Act, officers and directors who directed, authorized, assented to, acquiesced in, or participated in a corporation's contravention of environmental obligations may be personally liable. This creates direct personal exposure for directors of corporations engaged in activities with environmental risk — manufacturing, resource extraction, waste management.

The EPA s.194 provides a due diligence defence — a director who took all reasonable care to prevent the environmental contravention is not liable. Environmental compliance programs, policies, and active monitoring are the standard risk management tools.

Director Indemnification Under OBCA s.136

OBCA s.136 establishes two regimes for director indemnification:

Mandatory Indemnification

If a director was successful on the merits of any civil, criminal, administrative, investigative, or other proceeding, the corporation must indemnify them for all costs, charges, and expenses reasonably incurred. Success on the merits — acquittal in a criminal proceeding, dismissal of a civil claim — triggers mandatory indemnification.

Discretionary Indemnification

A corporation may (but is not required to) indemnify a director for proceedings where the director was not entirely successful, provided:

• The director acted honestly and in good faith with a view to the best interests of the corporation
• In a criminal or administrative proceeding, the director had reasonable grounds to believe their conduct was lawful

Indemnification agreements and board resolutions — entered before proceedings arise — are standard practice for public companies and increasingly common for private Ontario corporations. These arrangements ensure the director has a clear contractual right to indemnification and advance funding of legal costs during proceedings.

Directors and Officers (D&O) Insurance

D&O insurance covers personal liability of directors and officers for wrongful acts in their corporate roles — including breach of fiduciary duty, negligent misrepresentation, errors and omissions, and employment practices claims. D&O insurance is particularly important because:

• Corporate indemnification is unavailable for corporations in insolvency (when the risk is highest)
• Indemnification may be unavailable where the director was not acting in good faith
• Shareholders may object to corporate indemnification in derivative or oppression proceedings

Ontario lawyers advising boards on governance should consistently address D&O insurance adequacy — limits, exclusions, and Side A coverage (which protects individual directors when indemnification is unavailable).

Atticus for Ontario Corporate Lawyers Advising Directors

Directors facing personal liability exposure — wage claims, CRA assessments, oppression applications — require efficient, well-organized legal counsel. Atticus is designed for Ontario solo and small law firms and manages client intake, matter management, trust accounting (Law Society By-Law 9 compliant for retainer management), HST billing, and AI document analysis — at $149 CAD per lawyer per month.

Frequently Asked Questions

What are the fiduciary duties of an Ontario director under the OBCA?

Under OBCA s.134(1), every director must (a) act honestly and in good faith with a view to the best interests of the corporation (fiduciary duty), and (b) exercise the care, diligence, and skill that a reasonably prudent person would exercise in comparable circumstances (duty of care). Duties are owed to the corporation, not to individual shareholders (BCE Inc [2008]).

What is the business judgment rule in Ontario director liability?

The business judgment rule protects directors from liability for honest business decisions made in good faith, on an informed basis, without conflicts, and within the range of reasonable choices. Courts will not second-guess business decisions meeting these criteria. The rule does not protect bad faith decisions, undisclosed conflicts, or completely irrational choices.

What is a director's personal liability for employee wages in Ontario?

Under OBCA s.131, directors are jointly and severally liable for up to 6 months of unpaid wages and 12 months of vacation pay that became due while they were directors. A due diligence defence applies — positive steps to prevent the failure to pay may provide a defence.

When is a director liable for corporate tax and HST remittances in Ontario?

Under ITA s.227.1 and ETA s.323, directors are personally liable for the corporation's failure to remit source deductions and HST. The CRA must assess within 2 years of resignation. A due diligence defence applies — steps taken to prevent the failure (monitoring finances, implementing controls) may provide protection.

How does director indemnification work under the OBCA?

OBCA s.136 provides mandatory indemnification where a director was successful on the merits, and discretionary indemnification where the director acted in good faith with a view to the corporation's best interests. D&O insurance supplements indemnification, particularly for insolvent corporations where corporate indemnification is unavailable.
