What the certificate of authorization requires
A health profession corporation is a standard Ontario corporation wearing College-imposed constraints. The articles must restrict the business to the practice of dietetics and activities ancillary to it. Every share, voting and non-voting alike, must be owned by a member of the College of Dietitians of Ontario; the carve-out that lets family members hold non-voting shares exists only for physicians and dentists. The corporate name must include a shareholder's surname, indicate the profession, and end with Professional Corporation.
Only after the College issues its certificate of authorization may the corporation deliver dietetic services, and that certificate renews every year with the share register expected to still be in order. Your own registration and professional obligations continue unchanged; the College regulates you exactly as before, corporation or not.
What changes on day one, and what does not
Owners tend to overestimate what the structure alters clinically and underestimate what it alters administratively. The honest ledger looks like this:
| Question | Sole proprietor | Health profession corporation |
|---|---|---|
| Tax on profit left in the practice | Your personal marginal rate | Roughly 12.2% on the first $500,000 |
| Professional liability | Yours, carried by insurance | Still yours; the corporation adds nothing here |
| Who may own the practice | You | College of Dietitians members only |
| Annual filings | T1 with a T2125 | T2, corporate records, certificate renewal |
| Receipts and insurer profiles | Your name and registration number | Reissued in the corporate name; your registration number stays on them |
The profit test
Because member-only shares rule out income splitting, the case stands or falls on deferral: profit the household does not need, left inside the corporation at the small-business rate instead of coming out at your marginal rate. A counselling caseload alone has a natural ceiling in your clinical hours, and practices at that ceiling often spend what they earn. It is usually the second stream, corporate wellness contracts, group programs, consulting, that produces the reliable surplus the structure needs.
Set against the benefit are real recurring costs: the incorporation itself, the College's application and annual renewal fees, and a corporate return every year afterward. A share sale that reaches the $1.25 million lifetime capital gains exemption is possible for a qualifying practice but uncommon for a solo virtual caseload, so we weight it honestly rather than headline it. If the surplus is not there yet, staying a sole proprietor is the correct answer, and we will give it.
Contract work through the corporation, and the PSB line
A growing share of RD income is contracted rather than booked: a telehealth platform pays per consult, a multidisciplinary clinic fills two days a week, a long-term care home buys a block of hours. Routed through a health profession corporation, that income raises the one question that can make incorporating a mistake: the personal services business rules. If the CRA concludes you would reasonably be that client's employee were the corporation not standing in between, the corporation is a PSB for that income. The small-business rate disappears, the combined rate climbs to roughly 44.5% in Ontario, and deductions shrink to little beyond the salary the corporation pays you.
The facts that decide it are the ordinary employment tests, applied to your working week: who sets the schedule, whose platform and charting system the work runs through, whether you may send another RD in your place, whether you carry any financial risk, and how many clients the corporation actually serves. A corporation with its own caseload plus a platform contract sits comfortably on the business side; one whose only revenue is a single clinic that directs your hours does not. We read those contracts before the articles are filed, because this is the scenario where staying a sole proprietor quietly beats the corporation.
The sequence we run
Our Incorporation service files the articles with the dietetics restrictions, prepares the College application, and opens the CRA accounts the practice actually needs: corporate tax from day one, payroll when salary starts, and HST only if the taxable stream justifies it, because the corporation is a new taxpayer and any registration you held as a sole proprietor does not carry over.
Then comes the re-papering that determines whether the switch feels clean: receipt templates and insurer or direct-billing profiles moved to the corporate name, platform billing details updated in Practice Better or Jane, corporate-client agreements assigned, and the start date timed to a month-end so the two books never overlap. For a lean virtual practice there is often little to transfer beyond equipment and goodwill, and where a rollover is needed we paper it so the move itself triggers no tax. From there the pay mix belongs to Tax Planning & Advisory, and the whole engagement is quoted in writing after a free 15-minute discovery call.
