Director Conflict of Interest in Canada: Disclosure Rules, Duties, and Consequences

Directors of corporations incorporated under the Ontario Business Corporations Act (OBCA) or the Canada Business Corporations Act (CBCA) owe a fiduciary duty to the corporation: a duty to act honestly and in good faith with a view to the corporation's best interests. At its core sits the duty of loyalty — at the board table, the corporation's interests come first, ahead of your own.

A conflict of interest arises whenever a director's personal interests — financial or otherwise — could influence, or reasonably appear to influence, the decisions they make on the corporation's behalf. The classic example is a director with a financial stake in a contract the corporation is about to sign, but conflicts take many forms and are remarkably common in private companies.

The point most business owners miss: having a conflict is not itself wrongdoing. Conflicts are a normal part of business life, especially in closely held companies where directors wear multiple hats. What the law regulates is how the conflict is handled. A properly disclosed and managed conflict is usually unremarkable; a concealed one can unwind contracts, trigger personal liability, and hand ammunition to a disgruntled shareholder.

Conflicts of interest tend to arise in predictable patterns:

• Contracting with your own corporation: The director — or a company they own or control — supplies goods or services to the corporation, leases property to it, or buys assets from it.
• Sitting on two boards: The director serves on the boards of two companies that do business with, compete with, or negotiate against each other.
• Related-party transactions: The corporation deals with the director's spouse, family members, or family-owned entities.
• Setting your own compensation: A director's own salary, bonus, or management fees inherently involve a personal interest.
• Loans to or from the corporation: Shareholder loans, director advances, and personal guarantees place the director on both sides of a financial relationship.
• Competing interests: The director holds a significant stake in a competitor, key supplier, or major customer.

One related doctrine deserves mention: the corporate opportunity rule. A director who learns of a business opportunity through their role — an acquisition target, a customer contract, a property the company was pursuing — generally cannot take it personally, and Canadian courts have held directors accountable for diverting corporate opportunities even after leaving the board.

Both the OBCA and the CBCA require directors to disclose a material interest in a contract or transaction with the corporation. The statutes differ in detail, but the core obligations are the same.

A director who is a party to a material contract or transaction with the corporation — or who is a director or officer of, or has a material interest in, another party to it — must disclose the nature and extent of that interest, in writing or by having it recorded in the minutes.

Timing matters. Disclosure is generally required at the meeting where the contract or transaction is first considered; if the interest arises later, at the first meeting after the director becomes aware of it. Both statutes also permit a standing general notice: a director can declare once that they have an interest in a specified entity, covering future dealings with it.

Two features deserve emphasis. First, disclosure must be meaningful — it must convey the nature and extent of the interest, not merely that some interest exists. Second, the obligation belongs to the director personally: it is not the corporation's job to uncover the conflict, it is the director's job to declare it.

Disclosure alone is not the end of the story. The general rule under both statutes is that an interested director must not vote on the resolution approving the contract or transaction. The statutes carve out limited exceptions — typically matters such as directors' remuneration, indemnities and liability insurance, and contracts with affiliated entities — but otherwise abstention is the rule.

Good governance goes further. In most well-run boardrooms, the conflicted director does not merely abstain — they leave the room during deliberations so the remaining directors can speak candidly. The minutes should record both the abstention and the departure.

Careful compliance matters because both statutes provide a safe harbour. Where the director discloses properly and on time, the disinterested directors approve the contract (or the shareholders confirm it), and the contract was reasonable and fair to the corporation when approved, it is generally not voidable merely because of the director's interest, and the director is generally not required to account for profits. Following the process converts a dangerous transaction into an ordinary one; skipping it leaves both the deal and the director exposed.

When a director fails to disclose a conflict or votes on a matter in which they were interested, the consequences can reach the transaction, the director personally, and the corporation itself.

Voidable contracts: A contract tainted by an undisclosed director interest may be set aside on application by the corporation or a shareholder, and a court can make other orders it considers appropriate.

Accounting for profits: A director who profits from an undisclosed conflict — including a diverted corporate opportunity — can be ordered to hand those profits to the corporation, even where it suffered no obvious loss.

Oppression remedy: Both statutes let shareholders, and in some circumstances creditors, apply for relief from conduct that is oppressive or unfairly prejudicial. Director self-dealing is one of the most common foundations for an oppression claim, and courts have broad remedial powers, from compensation orders to compelled share buyouts.

Removal from the board: Shareholders can generally remove a director by ordinary resolution, and a discovered conflict often destroys the trust needed to keep a director in place.

Deal and financing risk: Buyers, lenders, and investors scrutinize related-party transactions during due diligence. Undocumented director dealings can delay financings, reduce purchase prices, or add indemnity demands to a sale.

The difference between a conflict that is a footnote and a conflict that becomes a lawsuit usually comes down to the paper trail. A practical documentation protocol looks like this:

1. 1.Collect standing declarations of interest from each director on joining the board, and refresh them annually
2. 2.Maintain a conflicts register so the corporation has a single, current record of declared interests
3. 3.Record every disclosure in the minutes — the nature and extent of the interest, that the director abstained, and whether they left the room
4. 4.Have the disinterested directors approve the transaction or, where appropriate, obtain shareholder confirmation
5. 5.Build a fairness record — independent valuations, third-party quotes, or market comparables showing the transaction was reasonable and fair at the time
6. 6.File everything in the corporate minute book, ready for the day a lender, buyer, or court asks

Contemporaneous records are the point. A resolution drafted five years later, in the middle of a shareholder dispute, carries a fraction of the weight of a minute entry made the week of the decision. This is work the corporate lawyers at Lamba Law handle regularly — from setting up conflict-of-interest protocols to papering related-party transactions completed informally in earlier years.

In owner-managed corporations, the director, shareholder, officer, and key employee are often the same person or small group. Nearly every significant decision touches someone's personal interest: compensation, dividends, shareholder loans, a lease of premises the owner holds personally, or a management contract with a holding company.

The statutory rules do not disappear because the company is small — in practice they matter most here, because closely held corporations are where conflicts eventually surface as litigation.

For a sole director and shareholder, the risk is not a boardroom fight but outside scrutiny: a tax audit questioning related-party terms, a lender reviewing the minute book, or a buyer's due diligence team. Written resolutions documenting dealings between the owner and the corporation — prepared at the time, not reconstructed later — answer those questions before they are asked.

For corporations with multiple shareholders, undisclosed self-dealing is among the most common seeds of an oppression claim. Two tools reduce that risk: a well-drafted shareholder agreement that pre-authorizes defined categories of related-party dealings, and a disciplined minute-keeping practice that creates a contemporaneous record protecting honest directors.

Handled with disclosure, disinterested approval, and a clean paper trail, a director conflict of interest is a routine governance event. Handled in silence, it is one of the most reliable ways to turn an ordinary business decision into years of litigation.
