Regulatory College Consent When Selling a Professional Practice in Ontario

Selling a health, legal, or other regulated practice in Ontario? Here's how to work out whether your college needs to approve or be told about the sale.

Key takeaways
  • Sellers often use "does the college need to approve this" loosely, when really there are at least three distinct questions: 1.
  • Many regulated professionals operate through a professional corporation or, for certain health professions, a health profession corporation.

If you're selling a dental practice, physiotherapy clinic, accounting firm, or law practice in Ontario, one question tends to catch sellers off guard: does your regulatory college need to sign off on the sale before it can close? The honest answer is that it depends — on the profession, on how the practice is structured, and on exactly what's changing.

Ontario's regulated professions are governed by their own colleges, each with its own rules about ownership, corporate structure, and reporting. There is no single, uniform answer that applies "to professionals" as a category. What's true for one regulated profession may not be true for another, and assuming your situation mirrors a colleague's deal is a common — and avoidable — mistake.

Three Different Things People Lump Together as "Consent"

Sellers often use "does the college need to approve this" loosely, when really there are at least three distinct questions:

  1. Does the sale itself need prior approval from the college before it can close?
  2. Does the college need to be notified of the change, even if formal approval isn't required?
  3. Does the corporate structure through which the practice operates — for example, a professional corporation — need to be updated or reissued because of the ownership change?

The answer to each can be different, and getting only one of them right doesn't mean you've covered the issue.

Why Professional Corporations Add a Layer

Many regulated professionals operate through a professional corporation or, for certain health professions, a health profession corporation. These corporate structures typically come with ownership restrictions tied to the professional's own licensing status — the shares generally have to be held in ways connected to a member of the profession, not simply anyone with the money to buy in.

That has direct consequences for a practice sale:

A Practical Way to Work Through It

QuestionWhy it matters
What profession, and which college, governs this practice?Requirements are set college-by-college — there's no shortcut that applies across professions
Is the practice held in a professional corporation, and does that corporation have a certificate of authorization or equivalent?Ownership-restricted corporate structures often need updating on a change of ownership
Is the buyer a member of the same regulated profession?This affects whether a share sale to that buyer is even structurally available
Does the college's current guidance require prior approval, notice, or nothing at all for this kind of transaction?Confirm directly with the college — don't assume based on another profession's rules or an outdated understanding
Are there client- or patient-facing notice obligations separate from the college's own requirements?Regulatory approval and client/patient notice are related but distinct obligations

Common Misconceptions

Frequently asked questions

How do I find out what my specific college requires?

Contact the college directly and ask about its current requirements for a change of practice ownership, and have your lawyer review your specific corporate structure alongside that guidance. Rules and processes can change, so don't rely on information that isn't current.

Does this apply the same way to an asset sale as a share sale?

Not necessarily — a share sale changes who owns the corporation itself, while an asset sale generally leaves the corporation with the seller and transfers specific assets to the buyer. Which structure you use can affect whether — and which — college requirements are triggered.

What if the buyer isn't a member of the same profession?

Depending on the profession and corporate structure, this can significantly limit how the deal can be structured, since ownership of a professional corporation is often restricted to licensed members. This is worth confirming very early, before you negotiate price or terms around a specific buyer.

Is this different from getting the college to approve a new practice location or a partnership?

It can overlap, but a change of ownership through a sale is its own category of event for many colleges, separate from opening a new location or adding a partner. Don't assume one type of notification covers the other.
