An individual can walk into an Ontario courtroom and represent themselves. A corporation cannot walk into a courtroom at all — it can only ever act through people. That distinction matters more than it might seem, because it shapes a very practical question many business owners run into: can I personally appear for my company in a lawsuit, or does it have to be a lawyer?

The answer depends heavily on which court the case is in.

The General Rule in Superior Court: A Lawyer Is Required

In Ontario’s Superior Court of Justice — the court used for larger and more complex civil claims — a corporation generally cannot represent itself the way an individual can. Corporations are normally required to be represented by a lawyer in Superior Court proceedings. An owner, director, or officer cannot simply stand up and argue the company’s case as if they were a self-represented individual.

This rule exists because a corporation is a separate legal entity from the people who own or run it, even though it can only act through those people in practice. Courts generally treat that separation as a reason to require a licensed lawyer to speak for it.

The Exception: Asking the Court for Leave

In limited circumstances, a court can grant leave (permission) for a corporation to be represented by someone other than a lawyer — for example, a director in a case where hiring a lawyer would cause genuine hardship. This is not automatic or common; it requires a specific request to the court, and the court retains discretion over whether to allow it. A business should not assume this exception will be available and should plan on retaining a lawyer for Superior Court litigation as the default expectation.

Small Claims Court Is Different

Small Claims Court is designed to be more accessible, and that extends to how corporations can appear there. A company can generally be represented in Small Claims Court by a properly authorized representative — such as a director, officer, or employee — without that person being a lawyer or a licensed paralegal. This is one of the practical advantages of Small Claims Court for smaller business disputes: the company does not necessarily need to retain outside representation just to show up and be heard.

Practical Implications for Small Business Owners

What Happens If a Corporation Tries to Proceed Without a Lawyer

If a corporation is required to have a lawyer and does not retain one, the case generally cannot move forward properly — pleadings may be struck, steps may be delayed, or the matter may not proceed until the corporation is properly represented. This can create serious practical problems if a deadline is approaching and no lawyer is yet in place, so it is worth addressing representation early rather than waiting until a procedural step forces the issue.

Frequently asked questions

Can I represent my own numbered company if I’m the sole director?

In Superior Court, generally no — the corporate representation rule applies regardless of how few people are involved in the company. In Small Claims Court, you would typically be able to appear as an authorized representative of the company.

What if my company can’t afford a lawyer for a Superior Court case?

You can ask the court for leave to have a non-lawyer represent the corporation, but this is discretionary and not guaranteed. It’s worth discussing your specific situation and options with a lawyer, including whether a limited scope retainer for part of the case might be workable.

Does this rule apply to partnerships and sole proprietorships too?

No — this rule is specific to corporations as separate legal entities. A sole proprietor is legally the same person as the business and can generally represent themselves the same way any individual can. Partnerships raise their own considerations depending on how the partnership is structured.

Can an employee who isn’t a director or officer represent the company in Small Claims Court?

Generally, yes, provided they are properly authorized by the corporation to act as its representative for that purpose. The court will typically want confirmation of that authority.
