Anonymised, illustrative composite. This is why a professional practice sale is structurally an asset sale between practitioners, and why the standard shorthand about non-voting shares is wrong twice over.
At a glance
A vision-care platform backed by non-professional capital had acquired retail optical businesses in two provinces and wanted its first Ontario clinical group: three optometry practices in one metropolitan area, each operated through its own professional corporation, enterprise value $12,600,000. Most of the value was goodwill sitting inside those corporations. The vendors' advisers proposed a share purchase, on a rationale that gets repeated across the sector: Ontario professional corporations can carry non-voting shares held outside the profession, so a non-voting class solves the ownership problem and the vendors get share-sale tax treatment.
The general rule is in Business Corporations Act s.3.2(2), which requires a professional corporation to satisfy all of the following, including: “All of the issued and outstanding shares of the corporation shall be legally and beneficially owned, directly or indirectly, by one or more members of the same profession” and “All officers and directors of the corporation shall be shareholders of the corporation.”
There is a carve-out, and the advisers had heard of it without reading it. O. Reg. 665/05 provides, in s.2(1), that “A physician corporation is exempt from the application of paragraph 1 of subsection 3.2 (2) of the Act”, and in s.3(1), that “A dentist corporation is exempt from the application of paragraph 1 of subsection 3.2 (2) of the Act”. Those are the two exemptions the regulation contains. Optometry is a self-governing profession under Schedule 1 to the Regulated Health Professions Act, 1991, so an optometry professional corporation is possible — and it sits squarely under s.3.2(2) paragraph 1, unmodified.
That alone ends the share sale. But the second error is the more useful one, because it survives the first. Even for the two exempt professions, the substituted rule does not admit an investor. Under O. Reg. 665/05 s.3(1), each non-voting share of a dentist corporation must be owned by a member of the College, or by “a family member of a voting dentist shareholder”, or by trustees in trust for a voting dentist shareholder's minor children. The physician rule in s.2(1) is drawn identically. That is an exhaustive list, and an unrelated corporate buyer appears nowhere on it.
So the widely repeated shorthand is wrong twice. It is wrong that dental corporations must be wholly dentist-owned — s.3(1) of the regulation says otherwise. And it is wrong that the carve-out opens the door to outside equity — it is a family-succession and income-splitting relief, and it was drafted as one.
The switch from a share purchase to an asset purchase moved roughly $3,900,000 of the consideration from proceeds in the vendors' hands to proceeds inside their corporations, changing the tax path entirely — see the 24-month rule that decides your capital gains exemption. The vendors' advisers quantified the difference and asked for a $740,000 uplift; the platform's position was that it had never been able to buy shares, so no value had been taken from anyone. Settled at $410,000, nine weeks behind the original timetable.
Four provisions, taken together, make an outside share purchase impossible rather than merely difficult. Paragraph 1 of s.3.2(2) puts every share in the hands of members of the same profession. Paragraph 2 requires all officers and directors to be shareholders, so a buyer cannot take a board seat either — the board is drawn from a shareholder pool it cannot join. Section 3.2(4) closes the proxy route: “An agreement or proxy that vests in a person other than a shareholder of a professional corporation the right to vote the rights attached to a share of the corporation is void.” And s.3.2(5): “Subject to subsection (6), a unanimous shareholder agreement in respect of a professional corporation is void unless each shareholder of the corporation is a member of the professional corporation.”
The regulatory side reinforces it. The Health Professions Procedural Code, Schedule 2 to the RHPA, provides in s.85.14(3) that “A health profession corporation shall not practise a health profession when it does not satisfy the requirements for a professional corporation under subsection 3.2 (2) of the Business Corporations Act or a requirement established under subsection 3.2 (6) of that Act.” And s.85.9 requires notice to the Registrar of a change in the shareholders who are members of the College, so a defective structure surfaces on the College's own file.
There is also a reason a financial buyer would not want the shares even if it could hold them. OBCA s.3.4(4): “A person is jointly and severally liable with a professional corporation for all professional liability claims made against the corporation in respect of errors and omissions that were made or occurred while the person was a shareholder of the corporation.”
An asset purchase. The three professional corporations stayed with the optometrists. The platform bought what is not the practice of the profession: equipment, leasehold improvements, the dispensary and frame inventory, the brand and the booking systems, plus the non-clinical staff. The corporations kept the clinical practice and contracted with the platform for premises, equipment, administration and marketing.
That structure has to be built carefully rather than aggressively, because a services agreement that in substance transfers control of the professional corporation is doing what ss.3.2(4) and 3.2(5) exist to prevent. Clinical decisions, fee-setting for professional services, and the retention and discipline of optometrists stayed expressly with the corporations. See buying a professional practice: share restrictions and who can own an Ontario accounting practice for the same shape in adjacent professions.
A corporation that does not satisfy s.3.2(2) must not practise the profession, under Code s.85.14(3). The immediate consequence is not a fine but a clinic that cannot lawfully see patients — and the s.85.9 notice obligation makes the defect visible to the regulator by design rather than by accident. The tax argument the vendors lost is worth keeping in proportion: a real cost, quantified at $740,000 and settled at $410,000, but never a reason to attempt a structure the statute forbids.
The tell was a sentence in the vendors' information memorandum that named no profession and no section: Ontario professional corporations permit non-voting shares to be held outside the profession. Which professions? Held by whom? Under which regulation? The answers narrow it to almost nothing: two professions, and only a College member, a family member of a voting shareholder, or a trustee for that shareholder's minor children. Whenever a structure rests on a carve-out, read the carve-out's own list before you price the deal on it.
