Selling a dental practice in Canada

A dental practice sale looks like an ordinary small business sale on the surface — find a buyer, agree a price, close the deal — but a dental college sits behind almost every step of it. Ownership of the corporation or practice is restricted to people who hold, or can obtain, the right professional standing, and the patient charts at the centre of the practice cannot simply be handed over the way a customer list would be in a typical retail sale. Sellers who plan around both of these realities from the outset generally have a smoother process than those who discover them once an offer is already on the table.

Who is allowed to own a dental practice

Every province regulates dentistry through its own college, and that college — not a general business registry — sets the rules for who may own a dental practice or hold shares in a professional dental corporation. In most provinces this means a licensed dentist, though several provinces allow narrower exceptions such as a dentist’s spouse or family members holding non-voting shares in specific circumstances. These rules genuinely differ from province to province and change over time, so a seller and buyer both need to confirm the current ownership rules with the relevant provincial college before a deal is structured, rather than assuming the answer from a different province or from a general reading of corporate law.

Who actually buys dental practices

The buyer pool ranges from a solo dentist buying their first practice, to an existing associate buying in gradually, to a dental service organization or group buyer that operates several practices and employs licensed dentists to run the clinical side. Each type asks different questions: an individual buyer usually focuses on what they can personally produce and finance, while a group buyer looks harder at systems, the hygiene department, and whether the practice can run well with more than one provider in the chair. Knowing which type of buyer is realistically in the market for a practice of your size and location shapes how it should be prepared and marketed.

Patient charts are not an ordinary business asset

Patient charts contain personal health information, and moving them from one custodian to another is governed by privacy law and by the college’s own record-keeping rules, not by the purchase agreement alone. In Ontario this sits under the Personal Health Information Protection Act, known as PHIPA, layered on top of the federal Personal Information Protection and Electronic Documents Act that applies across the country; other provinces have their own health-specific privacy statutes that play a similar role. Patients are generally entitled to know their records are moving to a new custodian, and the college typically expects the outgoing and incoming dentists to handle that notice and the retention of records properly — confirm the specific mechanics with your provincial college rather than assuming they match what another province requires.

Goodwill splits between the practice and the person

Some of a dental practice’s goodwill belongs to the practice itself — its location, its systems, its brand and its hygiene department — and transfers to a new owner with reasonable continuity. Some of it is personal to the selling dentist: patients who have trusted the same hands for twenty years, referral relationships built one appointment at a time, a chairside manner that does not come with the equipment. Advisors sometimes describe this as the difference between practice goodwill and personal goodwill, and how a deal splits the two affects both the price and how it is taxed, which is why a proper valuation treats them separately rather than lumping all goodwill together.

Equipment, technology and the lease

Buyers look closely at the age and condition of clinical equipment — digital imaging, sterilization systems, chairs — because replacing outdated technology is a cost that lands on the new owner almost immediately. A practice that has kept its equipment current tends to show better on diligence than one where the numbers look fine but the operatories have not been updated in a decade. The lease matters just as much: dental operatories require plumbing, electrical and structural buildouts that are expensive to replicate, so a lease with a long remaining term or a straightforward assignment clause protects value in a way that a short or restrictive lease does not.

Associates, staff and the transition period

Hygienists, dental assistants and any associate dentists working in the practice are often as important to patient retention as the selling dentist is, and a buyer will want to understand who is likely to stay through a change of ownership and who is not. A written transition period — where the outgoing dentist introduces the buyer to patients, works alongside them for a defined stretch, or remains available for questions — is one of the more effective ways to protect the value being sold, and it should be spelled out in the purchase agreement rather than left as an informal understanding between the two dentists.

Restrictive covenants and what they actually protect

Because patients can follow a trusted dentist to a new location fairly easily, agreements typically include a non-compete restricting the seller from opening or joining a competing practice nearby, and a non-solicitation clause covering former patients and staff, for a defined period. Whether these clauses hold up if challenged depends on how they are drafted and on rules specific to regulated professionals in the seller’s province, so have them reviewed by a lawyer experienced with dental practice sales rather than reusing a generic business-sale template.
