What is the difference between a director and an officer in an Ontario corporation?

An Ontario corporation must have at least one director. Directors are elected by shareholders and are responsible for overseeing the management of the corporation. They make high-level decisions, adopt bylaws, appoint officers, and have legal duties — including a duty of care and a fiduciary duty to act in the corporation's best interests.

Officers are appointed by the board of directors to manage the day-to-day operations. Common officer roles include president, secretary, treasurer, and chief executive officer. In a small owner-managed corporation, the same person often holds all director and officer positions simultaneously. There is nothing wrong with being both the sole director and the president.

The key distinction matters most for liability. Directors of Ontario corporations bear specific personal liabilities that officers generally do not — for example, directors can be personally liable for up to six months of unpaid employee wages, unremitted source deductions, and certain environmental obligations. Being an officer without being a director does not expose you to these director-specific duties.

When outside investors come in, governance becomes more formal: investor-shareholders often require board seats, and it becomes important to document decisions at the board level properly.
