Officers of an Ontario Corporation: Roles and Duties

Officers run an Ontario corporation day to day: the president who signs the lease, the CFO who approves payroll, the secretary who keeps the minute book. Most founders assume the Ontario Business Corporations Act (OBCA) dictates which positions you must fill and what each one does. It does not, and that shapes almost everything below.

This article is about officers only. For board-level duties, director liability, residency and how directors are elected and removed, read our companion guide on directors in an Ontario corporation.

What is an officer in an Ontario corporation?

The OBCA defines "officer" broadly: the offices listed below, anyone designated an officer by by-law or board resolution, and anyone who performs functions similar to those normally performed by such an office holder. That last clause captures de facto officers, who carry officer status without a title or a line in the minute book.

Here is the headline fact: the OBCA does not require any particular officer. Section 133 is permissive. Subject to the articles, the by-laws or a unanimous shareholder agreement, the directors may designate offices, appoint officers, specify their duties and delegate management powers. There is no obligation to have a president, a secretary or a treasurer. The statute names offices but assigns them no duties; duties come from your by-laws and the board.

Who appoints officers, and who can be one?

Officers are appointed by the board, not elected by shareholders. Appointment is by resolution at a directors' meeting or by written resolution signed by all the directors, and a copy must be kept with the directors' minutes.

The rules described here reflect the Ontario Business Corporations Act as of August 2026 and can change.

Eligibility is looser than most founders expect:

So one individual can be the sole shareholder, sole director and holder of every office of a private Ontario corporation, which is how most single-founder companies are set up. And an act by an officer is not invalid merely because a defect in the appointment is discovered later.

What do the different officers actually do?

Because the statute is silent on duties, the descriptions below come from by-law practice, not from law.

The secretary is the one role with real statutory anchors, because the corporation must keep a defined set of records and someone has to own them: articles and by-laws, any unanimous shareholder agreement, shareholder minutes and resolutions, a register of directors, the securities register, a register of ownership interests in land, a register of individuals with significant control, adequate accounting records and directors' minutes. Our guide to corporate records in Canada covers each one.

Two more hooks matter: a dissenting director may deliver written dissent to the secretary of the meeting before it ends, and conflict of interest disclosure can be made by requesting entry in the directors' minutes.

Officers, directors and shareholders: who holds which power?

Confusing the three groups causes most governance mistakes, especially when one person sits in every chair.

One override matters. A unanimous shareholder agreement can restrict the directors' powers in whole or in part, which limits how the board structures its officers. More in our guide on shareholders in Ontario.

What duties and liability do officers carry?

Section 134(1) applies to every director and officer without distinction. An officer must act honestly and in good faith with a view to the best interests of the corporation, and exercise the care, diligence and skill of a reasonably prudent person in comparable circumstances. Officers must also comply with the Act, the regulations, the articles, the by-laws and any unanimous shareholder agreement. No contract, by-law or resolution can relieve an officer of that duty or of liability for breaching it.

Conflict of interest rules apply too. An officer who is not a director must disclose forthwith after becoming aware the contract is to be considered, forthwith after becoming interested, or forthwith after becoming an officer. Failure can let a court set the contract aside and order the officer to account for profits.

Now the nuance founders rarely hear. Several of the harshest liabilities target directors only:

Do not read that as immunity. The Canada Revenue Agency's published position (IC89-2R3) is that officers, employees and others not legally appointed as directors, but who perform the functions a director would perform, may be liable as de facto directors. A president or CEO who genuinely directs the corporation's affairs can be assessed.

A corporation may also indemnify its officers and purchase directors and officers insurance, provided the person acted honestly and in good faith with a view to the best interests of the corporation. Put the indemnity in the by-laws.

What can the board never delegate to an officer?

The board can hand off day-to-day management, but the OBCA lists powers it cannot delegate to a managing director, a committee or an officer.

How are officers filed and removed?

Officers are reported to the Ontario Business Registry on the initial return, notice of change and annual return. Only the five most senior officers are reported.

The OBCA sets out no removal procedure for officers, so the board that appoints can remove by resolution. Directors, by contrast, are removed by shareholders. A managing director or committee cannot appoint or remove the CEO, CFO, chair or president, so that power belongs to the full board.

One caution: removing someone from an office does not end their employment. If the officer is also an employee, ending employment triggers Employment Standards Act minimums and possibly common law reasonable notice. The full statute is on Ontario e-Laws.

FAQ about officers of an Ontario corporation

What is the difference between directors and officers of a corporation?

Directors are elected by shareholders and manage or supervise the management of the business and affairs of the corporation. Officers are appointed by the directors to handle day-to-day management. Both owe the same duty of care under section 134(1), but several statutory liabilities, including unpaid wages and CRA remittances, target directors specifically.

Who qualifies as a corporate officer?

Anyone the board appoints to an office named in the OBCA or created by by-law or resolution. No residency, share ownership or board membership requirement applies. The definition also captures anyone performing functions similar to those normally performed by such an office holder, so de facto officers exist without any appointment paperwork.

Does an Ontario corporation need a president or a secretary?

No. Section 133 is permissive: the directors may designate offices and appoint officers, but the OBCA imposes no obligation to have a president, secretary or treasurer. In practice most corporations appoint at least a president and a secretary, because banks, landlords and counterparties expect a signing officer and a records custodian.

Can one person hold every office?

Yes. Two or more offices may be held by the same person, and one individual can be the sole shareholder, the sole director and the holder of every office of a private Ontario corporation. For offering corporations, at least one third of the directors must not be officers or employees, so that concentration is unavailable there.

Are officers personally liable for unpaid taxes?

The Income Tax Act and Excise Tax Act name directors, not officers, for unremitted source deductions and GST/HST. However, CRA's published position is that officers and others who perform the functions a director would perform can be assessed as de facto directors. A CEO who truly directs the corporation's affairs is exposed.
