Beyond Doctors and Lawyers: Which Other Professions Can Incorporate in Ontario?

Most people know that doctors and lawyers can incorporate their practices. Fewer realize how many other self-regulating professions in Ontario have the same option. If you're a licensed professional wondering which professions can incorporate in Ontario, the honest answer is: it depends on your specific profession's own governing rules, but the list is longer than most people assume.

This article walks through the general categories, what they have in common, and why you should always confirm eligibility with your own regulatory college before assuming.

Why "Professional Corporation" Is a Different Category

A professional corporation is formed under the Business Corporations Act (Ontario), but it's a distinct category within it. Not every occupation qualifies — only members of a profession whose own governing legislation and regulatory college permit incorporation, and only on the conditions that college sets.

Professions That Commonly Incorporate in Ontario

• Health professions. Physicians, dentists, chiropractors, optometrists, pharmacists, physiotherapists, psychologists, and a range of other regulated health providers commonly incorporate through their respective colleges.
• Legal professions. Lawyers and paralegals can incorporate through the Law Society of Ontario, subject to its rules.
• Accounting. Chartered Professional Accountants (CPAs) can incorporate through CPA Ontario.
• Other regulated professions. Depending on the profession's own legislation and college, additional professions — such as veterinarians and certain other licensed practitioners — may also be eligible.

This list isn't exhaustive, and it shouldn't be treated as one. Eligibility, ownership rules, and naming requirements are set profession-by-profession, not by a single central rule that applies to everyone equally. If your profession isn't mentioned above, that doesn't mean you can't incorporate — check directly with your regulatory college.

What Every Professional Corporation Has in Common

• A certificate of authorization is required. Before practising through the corporation, the professional's regulatory college must authorize it — incorporating alone isn't enough.
• Ownership is generally restricted. Voting shares are typically limited to licensed members of the same profession, sometimes with narrow family exceptions.
• Specific naming rules apply. The corporate name typically must include a shareholder's name and indicate professional corporation status.
• Personal liability for malpractice doesn't disappear. Incorporating protects against many ordinary business liabilities, but it does not shield a professional from liability for their own negligence in providing the professional service.

Professions That Generally Cannot Incorporate This Way

Not every business, and not every occupation, is a "profession" for these purposes. Trades, most retail and service businesses, and many other occupations don't have a professional-corporation regime at all — and that's not a disadvantage. They simply incorporate as ordinary Ontario business corporations, which is a straightforward and common choice with none of the extra college-imposed conditions described above.

How to Confirm Your Own Eligibility

Because eligibility lives with each profession's own regulatory college rather than a single central government list, the most reliable way to find out if you qualify is to go directly to the source rather than relying on a general article like this one.

• [ ] Contact your regulatory college and ask specifically about professional corporations, not just general incorporation
• [ ] Ask what ownership structure is required — who can hold voting shares, and whether any non-voting exceptions exist
• [ ] Ask what naming convention your corporation's name must follow
• [ ] Ask whether a certificate of authorization, or an equivalent college approval, is required before you can practise through the corporation
• [ ] Confirm what insurance or ongoing reporting obligations come with incorporating

Treating this as a direct question to your college, rather than an assumption based on what a colleague did, avoids a lot of rework later.
