A professional corporation (PC) lets a member of a regulated profession — physician, dentist, lawyer, accountant, engineer, and others depending on the province — carry on their practice through a corporation rather than as a sole proprietor. The core mechanics are consistent everywhere: your regulatory college must approve and permit the corporation, share ownership is restricted by that same regulator, and incorporation does not remove your personal liability for your own professional work. But the specifics — who qualifies, what shares can be held by whom, and the exact compliance calendar — are set province by province and regulator by regulator, not by one national rule. This guide covers the national pattern; for Alberta-specific rates and rules, see our Alberta professional corporation guide.
Who may incorporate, and under which regulator
Two conditions have to be met before a professional corporation can practise, regardless of province:
- The profession's governing legislation in that province permits incorporation. Not every regulated occupation can incorporate everywhere — the enabling legislation is set at the provincial level, profession by profession.
- The regulatory college or governing body for that profession approves the corporation and issues a permit. Incorporating under general corporate law is necessary but not sufficient — the college's own approval and permit are what actually let the corporation carry on the regulated practice.
Professions that commonly have this option, subject to their own province's rules, include physicians, dentists, lawyers, chartered professional accountants, engineers, optometrists, chiropractors, psychologists and veterinarians — but the specific list, and the exact conditions attached, vary by province. A practitioner moving provinces, or a firm operating across more than one, should confirm the local rule rather than carry over an assumption from elsewhere.
Share-ownership restrictions differ by profession and province
This is the area where professionals most often assume a rule that doesn't apply to them. Ordinary corporate law lets shares be owned freely; professional corporations are the exception, because the regulator wants to keep control of the practice with licensed members of the profession. In practice, colleges take one of two general approaches:
- Voting shares restricted to licensed members — some colleges require every voting share to be held by someone currently licensed in that profession, which rules out spouses, family trusts or non-licensed business partners holding voting equity.
- Non-voting shares open to family members — other colleges permit non-voting shares to be held by a spouse, adult children or a family trust, which is often used for income-splitting, while voting control stays with the licensed professional.
Because this is set college by college — not by one corporate-law default — the only reliable answer is to check the current rule with your own profession's regulator in the province where you practise, before structuring share ownership around an assumption. Our salary vs dividends guide covers the tax mechanics of dividends once share structure is settled, but it does not decide who is eligible to hold those shares — that's a regulatory question, not a tax one.
Remuneration mix: salary vs. dividends, qualitatively
Once the corporation is earning income, the practitioner faces the recurring decision of how to draw money out — and the trade-off is qualitative, not a fixed formula:
| Consideration | Salary | Dividends |
|---|---|---|
| RRSP contribution room | Builds room | Does not build room |
| CPP entitlement | Builds entitlement (and creates a CPP cost) | No CPP entitlement or cost |
| Administrative mechanics | Requires a payroll account, source deductions, T4 | Simpler — no payroll remittances |
| Deductibility to the corporation | Deductible expense | Paid from after-tax corporate income |
| Typical use | Building retirement income, predictable personal cash flow | Flexibility, avoiding payroll administration |
Most owner-managed professional corporations use a blend of the two, weighted toward whichever mix fits the practitioner's cash needs, retirement-savings strategy, and how much profit is meant to stay invested in the corporation versus be drawn out this year. This is genuinely a year-by-year modelling exercise, not a one-time decision — see the salary-vs-dividend calculator to run current numbers.
Professional liability and insurance
Incorporating changes the corporation's commercial liability exposure, but it does not touch the practitioner's personal exposure for their own professional work. A professional corporation can offer some protection against ordinary commercial debts and contracts of the practice — a lease default, a supplier dispute — but every regulator holds the individual practitioner personally accountable for the standard of their professional work, and that exposure is addressed through professional liability insurance, not the corporate veil. Confirming adequate coverage — and understanding what the corporate structure does and does not protect — belongs in the same conversation as the decision to incorporate, not as an afterthought.
Year-end and compliance rhythm
A professional corporation's annual compliance cycle typically runs:
- Corporate fiscal year-end financial statements and the T2 corporate return.
- The practitioner's personal T1, reflecting whatever salary and dividends were actually paid through the year.
- Payroll remittances and T4s if the corporation employs staff (including, where applicable, the professional's own salary).
- GST/HST filings if the practice bills taxable — as opposed to exempt — supplies.
- An annual corporate filing to stay in good standing with the corporate registry, plus whatever the regulatory college requires to keep the corporation's practice permit current.
Losing good standing with the college — not just the corporate registry — can put the corporation's ability to practise at risk, which is a compliance consequence most non-professional corporations never have to think about.

Frequently asked questions
Members of a regulated profession whose governing provincial legislation permits incorporation, and whose regulatory college or governing body approves the corporation and issues it a permit before it can practise. Physicians, dentists, lawyers, accountants, engineers and several other regulated professions can typically incorporate, but the specific list of eligible professions, the permit process, and every condition attached are set separately in each province — there is no single Canada-wide professional-corporations statute.
No. Each regulatory college sets its own rules for who may hold shares in a professional corporation for its profession, and those rules differ by province and by profession within the same province. Some colleges require all voting shares to be held by licensed members of the profession; others permit non-voting shares to be held by family members, often for income-splitting purposes, subject to conditions. Always confirm current share-ownership rules with your own regulator rather than assuming another profession's or province's rule applies.
There's no universal answer — it's a trade-off assessed each year, not a one-time choice. Salary creates RRSP contribution room and CPP entitlement and is a deductible expense to the corporation; dividends don't build RRSP room or CPP entitlement but can be administratively simpler and avoid payroll remittances. Most owner-managers use a blend, weighted by cash needs, retirement planning and how much profit stays in the corporation versus gets drawn out. Model your specific numbers rather than defaulting to a rule of thumb.
Only partially. A professional corporation can offer some protection against the ordinary commercial debts and contractual obligations of the practice, but it does not shield the individual professional from personal liability for their own professional negligence or malpractice — regulators hold the practitioner personally accountable for the standard of their professional work, and that exposure is addressed through professional liability insurance, not the corporate structure.
Annually: the corporation's fiscal year-end financial statements and T2 corporate return, the professional's personal T1 reflecting whatever salary and dividends were drawn, payroll remittances and T4s if the corporation employs staff, GST/HST filings if the practice bills taxable supplies, and an annual corporate filing to stay in good standing with both the corporate registry and the regulatory college — losing good standing with the college can jeopardize the corporation's permit to practise.
Not automatically. The value generally builds once income reliably exceeds what the practitioner needs to draw for living expenses, because surplus retained in the corporation can defer personal tax. Below that threshold, the incorporation cost, the regulator's permit and annual fees, and the ongoing cost of a separate corporate return can outweigh the benefit. It's worth modelling against your own numbers rather than assuming incorporation is always the right move.
