Executive Summary: Key Legal and Evidentiary Issues

• Central issue of whether misstatements about the number of active patient files in a dental clinic constituted dol (fraudulent misrepresentation) vitiating consent in a share sale transaction.
• Dispute over whether the buyer reasonably relied on the sellers’ representations or whether the buyer’s failure to independently verify the number of active files rendered its error inexcusable.
• Assessment of whether the number of active patient files was an essential element of the bargain, even though it was not expressly stipulated in the letter of intent or share purchase agreement.
• Evaluation of documentary and expert evidence to determine the real number of active patient files and to quantify the overpayment attributable to the misrepresentation.
• Challenge to the trial judge’s methodology for calculating the reduction in purchase price, including rejection of both parties’ experts and adoption of a per-file value.
• Appellate review focused on whether the trial judge’s findings on dol, causation, and damages contained a “palpable and overriding error” or merely reflected permissible factual appreciation of the evidence.

Facts of the case

The case arises from the sale of all the shares of a corporation operating a dental clinic, Clinique dentaire Rolland inc. (“the Clinic”). The sellers were Marie-Renée Godbout, in her personal capacity and as trustee of the Renée Godbout family trust, who controlled the Clinic’s share capital. The buyer was 9368-9792 Québec inc., which acquired 100% of the Clinic’s shares following pre-contractual discussions and negotiation of a letter of intent and a share purchase agreement. During negotiations, the sellers represented that the Clinic had 1,860 active patient files. The Court later found this figure was grossly overstated: in reality, the Clinic had only 734 active patient files at the time of the transaction, a shortfall of 1,016 files compared with what had been represented. This discrepancy went to the economic value of the Clinic: the buyer’s decision to pay the negotiated price depended significantly on the size and quality of the active patient base, as is typical in the acquisition of professional practices such as dental clinics. The buyer led evidence that it would not have agreed to pay such a high price for the shares had it known the true, much lower number of active files.

Issues at trial in the Superior Court

At first instance, before Justice Marie-Hélène Dubé of the Superior Court of Québec, the buyer brought an action in reduction of the sale price (diminution de prix). The central legal questions concerned vice of consent and dol in the context of a share sale: first, whether the inaccurate representation about 1,860 active patient files was a misrepresentation of an essential element sufficient to vitiate consent; second, whether that misrepresentation amounted to dol (fraud in the civil law sense), that is, whether the sellers’ conduct and statements were intentionally misleading; and third, whether the buyer’s reliance on those statements was reasonable, or whether its failure to carry out its own due diligence on the actual number of active files rendered its error inexcusable. The trial judge examined evidence showing that in an earlier draft of a valuation report for the Clinic, the sellers had asked the evaluator to increase the number of active files by adding 801 patient files previously purchased in 2015 from another dentist, Dr. Carmen Bélanger, even though no real effort had been made to integrate those patients into the Clinic’s active clientele. This supported the conclusion that the sellers were actively inflating the apparent size of the practice’s active patient base. The judge also considered contractual documents such as the letter of intent and the share purchase agreement. These did not expressly state the number of active patient files. The sellers argued that, because this number was not written into the contract, it could not be considered an essential element of the sale. The judge rejected that position, finding that the number of active files was nonetheless a key commercial parameter, much like equipment, instruments or dental supplies, even if not individually quantified in the text of the agreements.

Findings on dol, obligation to inform, and due diligence

On the question of vice of consent, the Superior Court held that the buyer’s consent to the transaction had indeed been vitiated by error, and that the error flowed directly from dol on the part of the sellers. The misrepresentation concerning the number of active patient files was found to be both false and material. It significantly overstated the size and value of the Clinic’s clientele and therefore distorted the economic basis of the buyer’s decision to pay the agreed price. The judge characterized the sellers’ declarations as dolosives—fraudulent misrepresentations made in a context where the sellers knew, or ought to have known, that the buyer was relying on their statements in valuing the business. The sellers attempted to shift blame onto the buyer, arguing that its representatives acted imprudently by relying solely on the sellers’ representations about active files and failing to perform their own verification or more robust due diligence. The court rejected this defence. While the buyer did not conduct a full independent audit of the patient records, the judge held that under the circumstances the buyer’s reliance on the sellers’ representations was not imprudent to the point of rendering its error inexcusable. The duty to inform and not to mislead remained primarily with the sellers, who controlled access to the Clinic’s internal data and had specific knowledge of the true number of active files.

Assessment of damages and price reduction

After concluding that there was a vice of consent caused by dol, the Superior Court proceeded to quantify the appropriate reduction in the sale price. Both sides had adduced expert valuation evidence to support their preferred methods of calculating the impact of the misrepresentation on price. The judge ultimately discarded the specific valuations proposed by each party’s experts, finding their methodologies unsatisfactory for the factual situation at hand. Instead, the judge developed her own rational, evidence-based calculation by attributing a value of 85.71 dollars per missing active patient file. This figure was grounded in the broader evidentiary record regarding the Clinic’s operations and financial performance. Applying this per-file figure to the 1,016 active patient files that had been falsely represented but were actually missing, the court concluded that the buyer had overpaid by a total of 87,081 dollars. The judge therefore ordered a corresponding reduction of the purchase price in that amount. Although the Clinic’s revenues and profitability improved after the transaction, the court held that this subsequent success did not negate the buyer’s right to a reduction of price tied to the misrepresentation. The buyer had to work harder and deploy additional efforts to build up the clientele that the sellers had originally represented as already existing. Moreover, the claim belonged to the buyer as purchaser of the shares, not to the Clinic as an operating entity, so the Clinic’s later profitability was not determinative of the buyer’s loss at the time of sale.

The sellers’ appeal to the Court of Appeal

The sellers appealed the Superior Court judgment to the Québec Court of Appeal. They attacked both the finding of dol and the causal link between the misrepresentation and the quantum of the price reduction. The appeal was framed as alleging reviewable errors in (1) the conclusion that dol existed, and (2) the conclusion that this dol generated recoverable damages justifying a reduction of the sale price. In essence, the appellants invited the Court of Appeal to reweigh the evidence, arguing that the trial judge improperly assessed the materiality of the number of active files and the buyer’s reliance on that number. They also submitted that, because neither the letter of intent nor the share purchase agreement explicitly identified the number of active patient files, this factor could not be treated as determinative in law. On the damages side, the sellers criticized the trial judge’s rejection of both parties’ experts and contended that her independent per-file valuation was arbitrary and unsupported by the evidence. As a result, they asked the Court of Appeal to interfere with the trial judge’s factual findings and reduce or eliminate the award.

Appellate standard of review and analysis

The Court of Appeal began by recalling the high level of deference that appellate courts owe to a trial judge’s findings of fact, particularly those involving assessments of credibility, weight of evidence, and inferences about parties’ intentions. Findings as to the existence of dol are quintessentially factual. As such, they can only be overturned if the appellants demonstrate a palpable and overriding error—a clear, determinative mistake in the trial judge’s analysis. The Court held that the sellers failed to meet this demanding threshold. The appellate judges noted that the sellers’ arguments essentially sought to have the Court re-try the case, reconsider the same body of evidence, and substitute a different appreciation for that of the trial judge. This is not the role of the Court of Appeal; its mandate is to correct serious, outcome-changing errors, not to reweigh evidence. On the essential-element question, the Court confirmed the trial judge’s reasoning that the number of active patient files was commercially significant even if not written into the letter of intent or share purchase agreement. The fact that neither document listed the precise number of active files did not neutralize its importance, just as they did not itemize quantities of equipment or supplies. Additional evidence—such as the sellers’ request that the earlier valuation report artificially include hundreds of additional files acquired from another dentist but never truly integrated—further underscored the centrality of active patient files to the valuation and to the buyer’s decision to purchase. The Court of Appeal held that this evidence properly supported the finding that the sellers knew the number of active files was important, and that they nonetheless overstated it, thereby engaging in dol.

Confirmation of damages and outcome

On the quantification of the price reduction, the Court of Appeal rejected the allegation that the trial judge’s approach was arbitrary. Even though the judge did not accept the exact analyses of either party’s experts, her own calculation method remained anchored in the evidentiary record. By assigning a value of 85.71 dollars per missing active file and applying it to the 1,016-file shortfall, she derived a logically explained overpayment of 87,081 dollars. The Court considered this to be a rational and transparent exercise of the trial judge’s fact-finding and damage-assessment function. It found no palpable and overriding error in her methodology or conclusion. Accordingly, the Court of Appeal dismissed the appeal in its entirety and confirmed the reduction of the purchase price ordered at first instance. The appellants were ordered to pay the costs of the appeal, although the judgment does not specify the exact monetary amount of those costs. In the result, the successful party across both levels of court is 9368-9792 Québec inc., which obtained and retained a judgment reducing the purchase price by 87,081 dollars, plus its taxable costs of justice on appeal, the precise figure of which cannot be determined from the decision.
