Every Ontario corporation runs on three roles. Shareholders own the company. Directors govern it. Officers run it. One person can hold all three roles at once, and in most small Ontario businesses one person does. The Ontario Business Corporations Act (OBCA) sets out what each role can and cannot do for provincially incorporated companies, and the Canada Business Corporations Act (CBCA) does the same for federally incorporated ones.
The three roles look similar from the outside. The law treats them very differently. A shareholder who owns every share still cannot sign a contract for the corporation unless the company also makes that person an officer or director with authority to act. A director can be voted out by the same shareholders who elected them. An officer answers to the board that appointed them. We see owners blur these roles constantly, and the confusion turns costly the moment a dispute, a sale, or a tax reassessment arrives.
This guide explains each role under Ontario law, the duties that attach to it, when personal liability can follow, and how the three fit together. It reflects how we set up and advise corporations day to day at our Toronto office.
Roles matter at scale too. As of December 2023, Ontario was home to 407,428 small employer businesses, and the province accounted for roughly 39.6 percent of all private sector employment in Canada (Key Small Business Statistics 2024). Most of those companies are owner managed corporations where the same people wear all three hats, which is exactly where getting the roles right pays off.
What Is the Difference Between a Shareholder, Director and Officer?
The difference comes down to one word for each role. Shareholders own. Directors govern. Officers operate. Shareholders supply the capital and elect the board. Directors set strategy and supervise the company. Officers carry out the daily work and report to the board. Each role gets its authority from a different source, and each carries its own duties and risks.
| Role | Core function | How the role is filled | Main legal duty |
|---|---|---|---|
| Shareholder | Owns the corporation through shares | Buys, subscribes for, or inherits shares | None to the corporation as an owner, but cannot abuse minority holders |
| Director | Governs and supervises the business | Elected by shareholders, consents in writing | Fiduciary duty and duty of care to the corporation |
| Officer | Runs daily operations | Appointed by the board of directors | Fiduciary duty and duty of care to the corporation |
What Is a Shareholder in an Ontario Corporation?
A shareholder is a person or company that owns one or more shares in a corporation. Owning shares is not the same as owning the corporation’s assets. The corporation owns its property, contracts, and bank accounts in its own name. Shareholders own a stake in the corporation itself, along with the rights that attach to their class of shares. Those rights are defined in the articles of incorporation and, where the company has more than one owner, in a shareholder agreement.
What Rights Do Shareholders Actually Hold?
Shareholders hold ownership and oversight rights, not management rights. Under the OBCA, common shareholder rights include the following.
- Voting to elect and remove directors. Shareholders elect directors by ordinary resolution, meaning a majority of the votes cast.
- Voting on fundamental changes. Changes such as amending the articles, amalgamating, or selling substantially all of the business need a special resolution, which means two thirds of the votes cast.
- Receiving dividends when the board declares them. Shareholders do not vote themselves a dividend. The directors decide whether and when to declare one.
- Sharing in the remaining property if the corporation winds up and pays its debts first.
- Inspecting core corporate records, such as the minute book, share register, and financial statements.
Shareholders also hold a powerful protection called the oppression remedy. Under section 248 of the OBCA, a shareholder can ask the court for relief when the conduct of the corporation or its directors is oppressive, unfairly prejudicial, or unfairly disregards their interests. This remedy is one of the main reasons multiple owners should put a shareholder agreement in place early.
What a Shareholder Cannot Do
Ownership stops at the boardroom door. A shareholder, even a sole shareholder holding every share, cannot do any of the following simply by virtue of owning shares.
- Manage the daily business or give orders to staff.
- Sign contracts that bind the corporation.
- Declare a dividend or issue new shares.
To do any of those things, the shareholder needs a second role. They must either sit as a director or be appointed as an officer. This is why a founder who owns 100 percent of a company still appoints themselves as director and officer at incorporation.
What Does a Director Do and What Duties Do They Owe?
A director governs the corporation. Section 115 of the OBCA gives the directors the power to manage or supervise the management of the business and affairs of the corporation. In practice the board sets strategy, approves budgets and major contracts, appoints the officers, and watches over the company’s compliance. Shareholders elect the directors, but once elected, directors answer to the corporation, not to the shareholders who voted for them.
Becoming a director takes a real step, not just a title. Under the OBCA, a person elected or appointed as a director must consent to the role in writing within 10 days. Without that consent, the appointment can fail.
The Two Core Duties Every Director Owes
Section 134 of the OBCA places two duties on every director, and both are owed to the corporation itself.
- Fiduciary duty. A director must act honestly and in good faith with a view to the best interests of the corporation. This means avoiding conflicts of interest, declining to take corporate opportunities for personal gain, and never using confidential information for private benefit.
- Duty of care. A director must exercise the care, diligence, and skill that a reasonably prudent person would exercise in comparable circumstances. This is a standard of informed, careful decision making, not a guarantee of perfect results.
Here is a point the original version of this article got wrong, and it matters. Many sources say directors owe their duty to the corporation and its shareholders. Under the OBCA, the statutory duty runs to the corporation. Courts protect honest, informed board decisions through the business judgment rule. The Supreme Court of Canada confirmed in Peoples Department Stores v. Wise and again in BCE Inc. v. 1976 Debentureholders that judges look at the quality of the process a board followed, not whether the outcome turned out well. Document your reasoning, gather real information, and manage conflicts, and the law gives your decisions room to breathe.
Who Can Be a Director in Ontario?
Section 118 of the OBCA sets the qualifications. A director must be an individual, not a corporation. The person must be at least 18 years old, must not be an undischarged bankrupt, and must not have been found incapable by a court or under mental health legislation.
One Ontario rule changed in a way many founders still miss. Until July 5, 2021, the OBCA required at least 25 percent of a corporation’s directors to be resident Canadians. Ontario repealed that residency requirement. You can now build an Ontario board entirely from non residents, which makes the province far friendlier to foreign founders setting up a Canadian subsidiary. The federal CBCA is different. It still requires at least 25 percent of directors to be resident Canadians, so the choice between provincial and federal incorporation can turn on who you want on your board.
A private Ontario corporation needs at least one director. A corporation that offers its shares to the public, called an offering corporation, needs at least three directors. Directors do not have to own shares unless the articles say so.
When Does a Director Face Personal Liability?
Limited liability protects shareholders from the company’s ordinary debts. It does not give directors a blanket shield. Ontario and federal law impose direct personal liability on directors for specific items, including the following.
- Unpaid wages and vacation pay. Section 131 of the OBCA makes directors jointly and individually liable for up to six months of unpaid employee wages and up to 12 months of unpaid vacation pay.
- Unremitted source deductions. Directors can be held personally liable for income tax, Canada Pension Plan contributions, and Employment Insurance premiums that the corporation failed to withhold and send to the Canada Revenue Agency.
- Certain regulatory and environmental obligations, where the director directed or permitted the breach.
Good governance reduces these risks. Keeping clean records, holding real board approvals, and using an indemnity agreement and directors insurance are practical protections we put in place for clients who serve on boards.
What Does an Officer Do?
An officer runs the corporation day to day. Section 133 of the OBCA lets the directors designate the offices of the corporation, appoint individuals to those offices, set their duties, and delegate management powers to them. Officers carry out the strategy the board sets and sign contracts within the authority the board grants them.
Officers owe the corporation the same two duties as directors. The fiduciary duty and the duty of care in section 134 apply to officers just as they apply to directors. An officer who steers a corporate opportunity to a side business or signs a deal they know harms the company breaches those duties, regardless of their title.
Common Officer Roles
The OBCA does not force a fixed slate of officers on a private company. The board chooses which offices to create. These are the roles most companies use.
| Officer | Typical responsibility |
|---|---|
| President or Chief Executive Officer | Leads overall strategy and represents the company at the highest level |
| Chief Financial Officer or Treasurer | Manages finances, budgeting, reporting, and banking |
| Chief Operating Officer | Oversees daily operations across the business |
| Secretary | Maintains corporate records, minute book, and filings |
Two or more offices can be held by the same person, and a director can also be an officer. In a small company, one founder is often the sole director and serves as both President and Secretary. That is permitted under Ontario law, as long as the records reflect who holds which role.
How Are Bylaws and Major Decisions Approved?
This is where role confusion causes the most damage, so it deserves a clear walk through. A corporation runs on its articles and its bylaws, and the two are not changed the same way. Bylaws are the operating rules of the company, covering matters like the number of directors, how meetings run, and how officers are appointed. The corporate minute book holds these records.
Under section 116 of the OBCA, the directors make, amend, or repeal bylaws by resolution. A bylaw the directors pass takes effect right away, but the directors must put it to the shareholders at the next shareholders meeting. The shareholders then confirm, reject, or amend it by ordinary resolution. If the shareholders reject the bylaw, it stops being effective from that date. So directors set the bylaws and shareholders confirm them. Shareholders do not draft bylaws on their own in the normal course.
Decisions split along the same line between board matters and shareholder matters.
- Board decisions. Declaring dividends, issuing or redeeming shares, appointing officers, and approving contracts are decisions for the directors.
- Ordinary shareholder resolutions. Electing directors and appointing the auditor pass on a simple majority of votes cast.
- Special shareholder resolutions. Fundamental changes such as amending the articles, amalgamating, or dissolving need two thirds of the votes cast.
Ontario also modernized how private companies pass written resolutions. Since July 5, 2021, a private corporation can pass a written ordinary resolution with a simple majority of shareholders instead of the old requirement for unanimous sign off, provided the company gives notice to any shareholder who did not sign within 10 business days. Special resolutions still need two thirds at a meeting or unanimous written approval. You can confirm the current text of these rules on the Ontario e Laws website and compare the federal rules in the Canada Business Corporations Act.
Can One Person Be the Sole Shareholder, Director and Officer?
Yes. Ontario law lets one individual own every share, sit as the sole director, and hold every office. This is the standard setup for a solo founder, and we register companies like this often. Choosing this structure is part of a wider business structure decision you make at the start.
Wearing three hats does not erase the obligations of any one role. A sole owner who is also the only director and officer still has to do all of the following.
- Keep a minute book and record decisions, even decisions you make alone, through written resolutions.
- File the annual return and keep the corporation’s information current on the Ontario Business Registry within 15 days of any change.
- Honour the director and officer duties and carry the personal liabilities that come with them, such as unpaid wages and unremitted source deductions.
The moment a second owner, an investor, or a successor enters the picture, the single hat structure needs to grow up. That is the right time to put a shareholder agreement in place, plan any share transfer, and think about business succession.
Roles at a Glance Comparison
This table summarizes how the three roles compare across the points that matter most in practice.
| Feature | Shareholder | Director | Officer |

| How the role ends | Sells or transfers shares | Removed by ordinary resolution, resigns, or term ends | Removed by the board or resigns |
| Personal liability | Generally limited to investment | Wages, vacation pay, source deductions, oppression | Breach of duty, statutory duties tied to the office |
Frequently Asked Questions
Can a shareholder be removed from a corporation?
No, not by a simple vote. Shareholders own their shares, and you cannot force an owner out unless a buyout right exists in the articles or in a shareholder agreement. This is the opposite of a director, who shareholders can remove by ordinary resolution. The gap between these two facts is exactly why a shareholder agreement matters once a company has more than one owner.
Does a director have to own shares in the company?
No. Under the OBCA a director does not need to be a shareholder unless the corporation’s articles require it. Directors are chosen for their judgment and oversight, not their ownership stake. In small companies the same person usually holds both roles, but the law does not force that overlap.
Can an Ontario corporation have only one director?
Yes. A private Ontario corporation can operate with a single director. Only an offering corporation, meaning one that distributes its shares to the public, must have at least three directors. Many successful Ontario companies run for years with one director who is also the sole shareholder and officer.
Do officers have to be directors?
No. The board appoints officers, and an officer may or may not also be a director. A company can hire a Chief Financial Officer who never sits on the board. It can also have a sole founder who is the only director and serves as President and Secretary at the same time. The OBCA allows one person to hold two or more offices.
Are directors personally responsible for company debts?
Generally no for ordinary business debts, because the corporation is a separate legal person. The exceptions are specific and serious. Directors can be personally liable for up to six months of unpaid wages and up to 12 months of vacation pay, and for income tax, Canada Pension Plan, and Employment Insurance amounts the company failed to remit. Strong financial oversight and clean records are the best defence.
Do I need a shareholder agreement if I own the whole company?
Not while you are the only shareholder. There is no one to agree with. The picture changes the instant a second owner, an investor, or a family successor comes in. At that point a shareholder agreement should set out voting, dividends, share transfers, and exit terms. Pairing it with a succession plan protects both the business and your family.
