Ontario Court Refuses to Fix Valuation or Discount Buy-Sell Price in Dental Partnership Dispute

What the Court decided

Justice Marc Labrosse rejected both of Dr. Dalios' requests, confirming that the Court's role in overseeing a buy-sell process is to ensure procedural fairness and enforceability, not to rewrite the commercial terms the parties agreed to or substitute judicial valuation for the parties' own commercial judgment.

1. No court-ordered valuation

Dr. Dalios asked the Court to determine the value of the dental practice before the buy-sell process proceeded, arguing that without a fixed starting valuation neither party could price their offer fairly. Justice Labrosse rejected this request.

The Court held that fixing a specific valuation was not consistent with the nature of a buy-sell mechanism. The fundamental design of a buy-sell clause is that each party independently determines the price they are willing to pay to acquire the other's shares, or to accept for their own. That price reflects each party's own assessment of the business, their risk tolerance, their financing capacity, and their desire to remain in or exit the enterprise. It is not tied to a formal appraisal and is not required to reflect independent market value.

Fairness in a buy-sell process arises not from a court-imposed price but from the symmetry of the mechanism itself: the party who names the price must be prepared to buy at that price or sell at it. That constraint creates a powerful incentive for realistic and honest pricing without judicial intervention.

Justice Labrosse also noted that the Court had reviewed written submissions and correspondence between counsel following oral argument to ensure the record was complete. This careful approach to procedural completeness reflects Ontario courts' commitment to ensuring that decisions in ongoing corporate disputes are made on a full and fair record.

2. No discount for the purchasing shareholder

Dr. Dalios also asked the Court to reduce whatever price he ultimately paid, on the basis that the dental practice was worth less with Dr. Price's departure. He argued that as the face of the practice and the dentist most responsible for its patient relationships, her exit would materially diminish the value of what he was acquiring.

Justice Labrosse refused this request as well. The Court found no legal or equitable basis to adjust the purchase price to reflect the risk of Dr. Price's departure, for a straightforward reason: the parties' shareholders agreement had already addressed that very risk.

The agreement included non-competition and non-solicitation provisions binding on Dr. Price. Those clauses were specifically designed to protect the purchasing shareholder against the risk that the departing dentist would take patients and goodwill with them. Having negotiated and agreed to those protections, Dr. Dalios could not then seek an additional price reduction on the basis of a risk the agreement had already allocated and addressed.

The Court confirmed that equitable adjustments to buy-sell prices are exceptional. They require a genuine legal or equitable justification, not simply a commercial argument that the business being acquired may be worth less after the vendor departs. Contractual certainty and respect for negotiated risk allocation take precedence.

Why this decision matters for Ontario professionals and shareholders

The Dalios v. Price decision carries practical lessons that extend well beyond dental corporations. Any professional or business owner who operates through a corporation with co-shareholders should understand what this ruling means for their own arrangements.

Buy-sell clauses are enforced as written, not as wished

Courts will implement buy-sell mechanisms according to their terms. If the clause does not require a court-ordered valuation, the court will not provide one. If the clause does not provide for a price discount reflecting one party's departure, the court will not impose one. The practical implication is that the drafting of a buy-sell clause is not a formality. Every significant contingency (how valuation is determined, what happens when the departing party is the key income generator, how non-competition obligations interact with the pricing mechanism) needs to be addressed in the agreement itself.

Non-competition clauses and buy-sell pricing are interconnected

This case illustrates a point that is often overlooked in shareholders agreement drafting: the non-competition and non-solicitation obligations that apply on exit are part of the commercial deal that determines the buy-sell price. If you are a purchasing shareholder who relies on those protections to justify paying a higher price for shares in a business that depends on the departing co-shareholder, those protections need to be robust, clearly drafted, and enforceable. Courts will treat them as the parties' negotiated answer to the departure risk question.

Court-supervised buy-sell processes can generate significant litigation costs

This case demonstrates that even after a court orders a buy-sell process to resolve a shareholder deadlock, disputes over the implementation of that process can generate further hearings, motions, and cost exposure. Clear buy-sell provisions that address valuation methodology, timing, and the allocation of departure risks reduce the likelihood of these secondary disputes arising. Prevention through good drafting is significantly less expensive than resolution through litigation.

Valuation is a commercial, not a judicial, exercise

Unless a shareholders agreement specifically requires a formal appraisal or court-fixed valuation, courts will leave pricing to the parties. If you are entering a buy-sell process and believe that a formal business valuation is necessary to achieve a fair outcome, ensure your agreement requires it. Relying on the court to impose one after the fact is not a reliable strategy, as this case confirms.

The decision applies equally to incorporated professionals in BC

While Dalios v. Price was decided in Ontario, the principles it applies are consistent with how BC courts approach buy-sell disputes. BC's Business Corporations Act governs professional corporations and closely held companies in BC, and BC courts similarly enforce buy-sell provisions as written and decline to substitute judicial valuation for contractual mechanisms. The practical lessons from this decision are equally relevant to dentists, doctors, lawyers, and other professionals operating through professional corporations in British Columbia.

What professionals and shareholders should take from this case

The Dalios v. Price decision reinforces four practical priorities for any professional or business owner operating through a shareholders agreement with a co-shareholder.

Draft your buy-sell clause with the exit scenario in mind

The most common drafting failure in buy-sell clauses is addressing the mechanics of the process without addressing the commercial realities of exit. Who sets the price? Is a formal valuation required? What happens when the departing shareholder is the key income generator or client relationship holder? What non-competition and non-solicitation obligations apply, and how do they interact with pricing? These questions need answers in the agreement, not in court.

Treat non-competition clauses as part of the pricing deal

If your shareholders agreement includes non-competition or non-solicitation obligations on the departing shareholder, understand that courts will treat those as the parties' agreed mechanism for managing departure risk. If those protections are inadequate, weakly drafted, or potentially unenforceable, they will not be supplemented by a judicial price reduction. Get them right in the first place.

Seek legal advice before the buy-sell process begins

Once a buy-sell notice is triggered or a court orders a buy-sell process to proceed, the parties' legal positions crystallize quickly. The price a party names, the response they give, and the arguments they raise in court are all consequential decisions that benefit from legal advice before they are made, not after.

Understand that litigation costs accumulate

The Dalios v. Price case was a follow-up hearing after the original buy-sell order, addressing two relatively discrete issues. It still generated contested court proceedings. The total cost of the shareholder dispute between these two dentists, from the original application to the buy-sell implementation hearing, will have been substantial. Clear, well-drafted agreements and early legal advice are the most cost-effective tools available to shareholders in closely held corporations.
