Professional Corporations for Health Professionals in Canada (2026)

A professional corporation is a company a regulated health professional is allowed to practise through, once the profession's college has signed off on it. In Ontario, British Columbia, Saskatchewan, Manitoba, Nova Scotia and New Brunswick, a physiotherapist, chiropractor, psychotherapist or massage therapist who wants to bill through a company needs the college's certificate or permit before the first invoice, and the shares, directors and name are restricted by statute. Alberta imposes that regime on six professions only, and Quebec lets each Order write its own rule. The tax reason to bother is the small business rate: 9% federal plus 0% to 3.2% provincial on the first $500,000 of active income, against a personal marginal rate of roughly 36% to 47.5% at $150,000 to $180,000.

This guide is for a clinic-based practitioner who consistently earns more than they spend. It is not for someone on a T4, or for someone who needs every dollar they bill. Every rule and rate was checked at the statute, the college fee page or the CRA page on June 30, 2026.

What is a professional corporation, and why can I not just incorporate a normal company?

An ordinary corporation cannot practise a regulated profession. Ontario's Business Corporations Act, sections 3.1 to 3.4, allows it only where the profession's own Act permits, and only if the corporation meets four conditions in section 3.2(2): all issued shares owned by members of the same profession (a regulation can carve out exceptions), every officer and director a shareholder, "Professional Corporation" or "Société professionnelle" in the name, and articles that restrict the business to the profession. The Regulated Health Professions Act adds the piece that matters day to day: the college issues a certificate of authorization, and until it does, the corporation cannot practise. The College of Physiotherapists of Ontario says operating your practice as a corporation without registering it with the College is illegal.

Two things follow. The corporation does not shield you from your own professional negligence; section 3.4 leaves the member's professional liability where it was. What it protects is the business side: the lease, the loan, the equipment contract. And the family share structures lawyers set up for physicians do not transfer. In Ontario, O. Reg. 665/05 lets physicians and dentists, and only them, issue non-voting shares to a spouse, child or parent, or to a trustee for minor children. A physiotherapist, psychotherapist, chiropractor or RMT in Ontario cannot give a spouse a single share. British Columbia and Saskatchewan allow family non-voting shares, Manitoba can allow them through the permit, and Quebec goes further, so where you practise decides the structure before any tax planning starts.

Which provinces allow health-profession professional corporations, and on what terms?

Physiotherapy is the reference profession, with Ontario fees for four professions. Other colleges follow the same statute but set their own fees and name rules. Fees are CAD, read on June 30, 2026.

How much tax does a professional corporation save?

The federal small business deduction taxes the first $500,000 of active business income at 9%. Each province adds its own rate.

"Save" needs a correction. A professional corporation defers tax; it rarely eliminates it. Money left in the corporation is taxed once at the small business rate and again personally when it comes out as a dividend, and the system is built so the two layers roughly equal the personal tax you skipped. The gain is timing: you invest or pay down debt with dollars taxed at 12.2% instead of 44%, and you take the money out in years when your rate is lower, such as parental leave or retirement.

A worked example: an Ontario physiotherapist netting $180,000

Take a physiotherapist whose share of clinic billings, after the split and expenses, is $180,000, and who needs $120,000 to live on. As a sole proprietor the whole $180,000 is personal income. Through a professional corporation, the corporation pays a $120,000 salary and keeps $60,000, on which it pays 12.2%, or $7,320, leaving $52,680 invested inside the company.

Taken personally, that $60,000 sits in the $120,000 to $180,000 band. For 2026 the federal rate from $117,045 to $181,440 is 26%; Ontario charges 11.16% to $150,000 and 12.16% to $220,000, and its surtax of 20% then 36% of Ontario tax above two thresholds lifts the provincial piece by 56% at this income. The marginal rate is about 43.4% on the first $30,000 of the band and 45% on the next $30,000, roughly $26,500 of personal tax. The corporation paid $7,320. The difference, about $19,200, is tax deferred for the year, not cancelled. Repeat it for five years and the deferred money compounds inside the company, which is the real case for incorporating.

The passive income grind

Once the retained money is invested, the investment income counts against the small business limit. Under subsection 125(5.1) of the Income Tax Act, the $500,000 limit falls by $5 for every $1 of adjusted aggregate investment income above $50,000 and disappears at $150,000. A corporation earning $60,000 of interest and dividends loses $50,000 of its limit. That is years away for most practitioners, but it is why retained money is usually invested for capital gains rather than interest.

The Quebec exception

Quebec grants its small business rate only to corporations whose employees are paid for at least 5,500 hours in the year, with a straight-line reduction between 5,500 and 5,000. A corporation whose only worker is the physiotherapist cannot get there: 40 hours a week for 52 weeks is 2,080. It pays Quebec's general 11.5%, a combined 20.5% instead of 12.2%, so the deferral is smaller. Finances Québec announced on April 29, 2026 (Revenu Québec relayed it on May 4) that the small business rate drops from 3.2% to 2.2% for taxation years beginning after April 29, 2026; the hours condition did not change.

Can my spouse or family receive income from the corporation?

Only if two gates open. The first is provincial: the college must allow the family member to hold shares at all, and in Ontario that is physicians and dentists only. The second is the tax on split income in section 120.4 of the Income Tax Act. Dividends paid to a family member from a private corporation are split income taxed at the top marginal rate unless an exclusion applies. Two exclusions matter here: the excluded business, where the family member is actively engaged on a regular, continuous and substantial basis, deemed met at an average of 20 hours a week in the year or in any five prior years; and the spouse of a practitioner who is 65 or older in the year (the Act's wording is having reached 64 before the year). The excluded shares route, the 10% votes-and-value test many business owners use, is closed: the definition excludes professional corporations outright and any corporation earning 90% or more of its income from services.

So a spouse who runs the front desk, the billing and the books for 20 hours a week can be a non-voting shareholder in British Columbia, Saskatchewan, Manitoba or Quebec and receive dividends at their own rate. A spouse who does nothing in the practice cannot, anywhere. A reasonable salary for real work is allowed in every province, with or without shares.

Should the corporation pay me a salary or dividends?

Salary is deductible to the corporation, creates RRSP room and builds CPP. In 2026 the CPP contribution is 5.95% of earnings between $3,500 and $74,600, a maximum of $4,230.45 each for employee and employer, plus 4% on earnings from $74,600 to $85,000, a maximum of $416 each. On a salary of $85,000 or more the two sides total $9,292.90, the same as a sole proprietor pays, so CPP is not a reason to incorporate or not. Employment Insurance does not apply: section 5(2)(b) of the Employment Insurance Act excludes employment by a corporation where the person controls more than 40% of the voting shares. No premiums, no benefits.

Dividends carry no CPP, create no RRSP room, and come with a credit meant to offset the corporate tax already paid. Most practitioners take a salary large enough to fund the RRSP and CPP they want, and dividends for the rest. A salary means a CRA payroll account, remittances and a T4 every February. Wagepoint runs a one-person payroll at $20 a month plus $4 per employee for one pay run a month, or $40 plus $6 for unlimited runs, with CPP, EI and income tax calculated and remitted to the CRA, T4s filed and a sync to Xero, and a $50 gift card after your first payroll through our link. Our Wagepoint review covers the owner-only setup.

When is a professional corporation not worth it?

When there is nothing to leave in it. The deferral exists only on income you do not need. A practitioner netting $110,000 who spends $110,000 gets no deferral, pays the college $774 and then $283 a year (Ontario physiotherapy), and pays for a corporate tax return, a minute book, an annual return, bookkeeping and payroll. There is no magic threshold, because the threshold is your spending, not your billing. Below roughly $100,000 to $120,000 of net professional income, almost nobody retains enough to cover the fixed cost; above about $150,000, almost everybody does. Between the two, the answer is a budget, not a rate. Two more reasons to wait: you may leave practice or move provinces within two years (each college issues its own certificate), or your income comes from one clinic under an arrangement that looks like employment.

I bill a clinic as a contractor. Does a corporation change the personal services business risk?

It creates it. The personal services business rules in subsection 125(7) of the Income Tax Act target exactly this shape: an "incorporated employee" who owns the corporation and who, without it, would reasonably be regarded as an employee of the clinic. If the CRA applies the label, the corporation loses the small business deduction and the general rate reduction and pays an extra 5%, which is 33% federal plus the provincial general rate, 44.5% in Ontario, with deductions essentially limited to the salary and benefits it paid you. The one clean exception, more than five full-time employees throughout the year, does not describe a solo practitioner.

The test is the usual one: control over hours and methods, who owns the equipment, chance of profit and risk of loss, and integration into the clinic's business. A physiotherapist who sets their own schedule, treats at two or three clinics, carries their own liability insurance and books some of their own patients looks like a business. One who works fixed shifts at a single clinic on its software with its patients looks like an employee, and a corporation in the middle does not change that. Our guides to the CRA's personal services business rules and to associate agreements at health clinics cover the contract terms that decide it.

One GST/HST note. Physiotherapy, chiropractic, psychological and, since June 20, 2024, psychotherapy and counselling therapy services rendered to an individual by a practitioner are exempt under section 7 of Part II of Schedule V to the Excise Tax Act. CRA Memorandum 25-3 notes that a subcontract with a clinic is a second transaction, between your corporation and the clinic, and the written agreement decides whether that one is exempt. See when a practitioner must register for GST/HST.

How do I set up a professional corporation, step by step?

1. Start with the college, not the registry. Its certificate or permit guide fixes the name format, the share restrictions and the wording the articles must carry. Generic articles fixed later cost a second government fee and a month.

2. Incorporate provincially with the restricted articles. Ownr costs $499 in year one at Ownr's regular price for the Online Minute Book plan (Ownr states this includes the government and filing fees; it renews at $199 a year) or $998 for the Managed Corporation plan (renews at $599), with 15% off through our link plus up to $300 RBC cash back when you open an RBC business account. Its product and help pages did not mention professional corporations when we checked in June 2026, and its own guide says most people will need a lawyer for one, so confirm in Ownr's chat that it will file your college's restricted articles before paying; our Ownr review covers the plans. Venn incorporates in Ontario only, with $250 to $350 credited back through our link (terms on our Venn incorporation page); ask the same question.

3. Use a lawyer when the structure is not one member with one class of shares. Family shareholders, a Quebec non-member shareholder, a trust for minor children, two practitioners in one corporation, or a clinic buy-in all need a shareholders' agreement and articles the college will accept.

4. Apply for the certificate or permit. Send the articles, certificate of incorporation, corporate profile report and shareholder declaration with the fee ($774 for an Ontario physiotherapist, $300 in British Columbia, $250 in Saskatchewan). Do not bill a patient or a clinic through the corporation until it arrives.

5. Register with the CRA. The business number and corporate tax account come with incorporation; add a payroll account if you will take a salary, and a GST/HST account only if you make taxable supplies.

6. Open the corporate bank account. Every dollar the corporation bills must land in its own account. Venn charges $0 monthly, pays 2% interest on CAD and USD, converts at 0.45% FX, holds funds at Bank of Montreal with CDIC eligibility, and takes corporations and registered sole proprietors; it is not available in Quebec, and there is up to $500 in signup bonuses through our link.

7. Set up the books before the first invoice. A corporation files a T2 with financial statements, so the bookkeeping must be clean from day one. Xero plans are $25, $60 and $80 CAD a month with unlimited users, 80% off for 6 months through our partner link; our Xero for Canadian practices guide shows the chart of accounts a clinic-based practitioner needs.
