Anonymised, illustrative composite. Ontario limits the family-share carve-out to two professions and one narrow list of relatives. Alberta runs the identical idea through a different statute, for four professions — and a buyer's counsel who had just closed an Ontario file nearly unwound a structure that was never broken.
At a glance
A national dental and vision-care consolidator, having just closed an Ontario optometry acquisition on an asset-purchase basis because the target corporation could not lawfully carry a non-professional shareholder, turned to its next target: a single-location Alberta dental practice, enterprise value $4,650,000, run through a professional corporation the dentist had incorporated a decade earlier.
The share register showed the dentist holding all voting shares and two non-voting classes: 20% held by his spouse, and a further 10% held by a trustee for a discretionary trust naming his two minor children as beneficiaries. An Alberta accountant had built the structure three years before the sale process began, as an ordinary income-splitting plan.
The buyer's due-diligence counsel had drafted the Ontario file's share-structure memo two weeks earlier, and applied the same reasoning here: a professional corporation providing regulated health services can only be owned by members of the profession, subject to a narrow carve-out that, on the Ontario file, reached only physician and dentist corporations and permitted non-voting shares solely for a College member, a family member of a voting shareholder, or a trustee for that shareholder's minor children. Read against an Alberta dental corporation with a spouse and a children's trust on the register, the memo's conclusion was that the structure looked closer to compliant than the optometry file — dentistry, after all, was one of the two exempt professions — but counsel still wanted confirmation from Alberta counsel before relying on a structure built under legislation nobody on the deal team had actually read.
That caution turned out to be the right instinct, for the wrong reason. The Ontario carve-out and the Alberta carve-out are not the same regulation extended across a border. They are two different statutes, administered by different regulators, and Alberta's version is not the narrower of the two.
Enterprise value $4,650,000. Family non-voting interest: 20% to the spouse, 10% to the children's trust, 30% combined. A preliminary opinion from the buyer's Ontario counsel, before Alberta counsel was retained, estimated a share buy-back and re-issuance to correct what it assumed was a defect at roughly $70,000 in legal, valuation and tax advice, plus four to six weeks added to the closing timetable while the family's own advisors negotiated a buy-back price for shares nobody needed to sell.
None of that was spent. Once Alberta counsel confirmed the structure against the Health Professions Act, the deal closed on the family's existing share register with no restructuring at all.
Alberta regulates professional corporations for four colleges under one statute, not one regulation per profession. Section 106(1) of the Health Professions Act restricts the corporate-name protection, and with it the professional-corporation regime, to a regulated member “of the College of Physicians and Surgeons of Alberta who is a physician, surgeon or osteopath… of the College of Dental Surgeons of Alberta, of the College of Chiropractors of Alberta, or… of the Alberta College of Optometrists.” Four colleges, one section, one downstream ownership regime for all of them.
Section 109(1)(e.1), added by S.A. 2009, c. 51, s. 1 — Bill 53, proclaimed after the dentist's corporation was already registered but before the family shares were issued — sets out exactly who may hold the non-voting shares: the registrar must be satisfied “that the legal and beneficial ownership of all the issued non-voting shares of the professional corporation is vested in one or more of the following persons: (i) one or more regulated members of the college who are also voting shareholders; (ii) in respect of any regulated member of the college who is also a voting shareholder, one or more of the following persons: (A) the spouse of the regulated member; (B) the common-law partner of the regulated member; (C) a child of the regulated member; (D) a trust, all of the beneficiaries of which are minor children of the regulated member.” The dentist's spouse and his children's trust are both squarely on that list.
The corresponding liability rule survives the family shares intact. Section 107 provides that, despite anything in the Business Corporations Act, “every voting shareholder of a professional corporation is liable to the same extent and in the same way as if the shareholder were, during that time, carrying on the business of the professional corporation as a partnership or, if there is only one voting shareholder, as an individual providing professional services.” The non-voting family shareholders carry none of that exposure — the liability rule reaches voting shareholders only, and the dentist was the only one.
What makes the Ontario comparison actively misleading rather than merely different is scope. Ontario's O. Reg. 665/05 exempts two professions — physician corporations under s.2(1) and dentist corporations under s.3(1) — from the Business Corporations Act's all-shares-same-profession rule, and reaches no other regulated health profession at all. Alberta's s.109(1)(e.1) sits inside the Health Professions Act itself and reaches every college listed in s.106(1): physicians, dentists, chiropractors and optometrists alike. A structure that would fail in Ontario for an optometrist, a chiropractor, or any profession other than the two named in the regulation is not automatically a defect for the same profession in Alberta, and the reverse error is just as available: assuming Alberta must be at least as permissive as Ontario, for a profession Alberta has not in fact listed, would be exactly the wrong direction of the same mistake.
Alberta counsel confirmed the share register against the Health Professions Act and against the College of Dental Surgeons of Alberta's own professional-corporation records, which listed the spouse and the trust as registered non-voting shareholders consistent with s.109(1)(e.1). The buyer's proposed pre-closing buy-back was withdrawn before it was ever raised with the family. The share purchase agreement closed on the existing capital structure, with representations confirming continued compliance with ss.106 to 115 rather than a restructuring covenant.
Had the buyer proceeded on the Ontario-derived assumption and required the buy-back, the family would have been asked to unwind a lawful, three-year-old income-splitting structure for no regulatory reason, at a cost the buyer's own preliminary estimate put near $70,000 before accounting for the tax consequences of a forced share redemption to people who had done nothing wrong. It would also have signalled to a family mid-negotiation that the buyer's counsel had not checked the statute actually in force in the seller's own province — a poor way to open a closing.
The tell was procedural, not textual: a memo written for one province's statute being read onto another province's facts without anyone pulling the second statute first. The substantive tell for a reviewer checking this kind of file is narrower and reusable — ask which colleges the ownership carve-out actually lists, by name, in the statute or regulation that grants it. A carve-out described only as “the non-voting share rule for professional corporations,” with no colleges named, has not yet been checked against the province and profession actually on the deal.
