Executive Summary: Key Legal and Evidentiary Issues

• Timing of contract formation for the sale of Gaumond’s shares (May 2015 vs January 2016) determined whether later negotiations with the third-party buyer could vitiate consent.
• Allegations of dol (fraudulent concealment) focused on Bournival’s failure to disclose parallel negotiations with Charbonneau at a higher valuation multiple (4.5 then 4.35 vs 3.5).
• Scope of the contractual duty of good faith and loyalty between long-standing co-shareholders, including obligations of disclosure under unanimous shareholder agreements.
• Prescription (limitations) analysis on when Gaumond knew or should have known of the alleged fault, damage, and causal link, given his role as trustee and access to certain transaction documents.
• Causation issues regarding whether Gaumond would realistically have agreed to sell to Charbonneau under the more onerous post-closing conditions imposed on Bournival.
• Quantum of damages framed as the difference between the price actually paid to Gaumond and the hypothetical higher price at Charbonneau’s coefficient, but ultimately not recoverable due to prescription and lack of causal link.

Factual background

Jean-Yves Gaumond and Robert Bournival were long-time co-shareholders of an insurance brokerage firm, Deslauriers et Associés Inc. They each held roughly 43.4% of the shares, directly and through similarly structured family trusts. Their relationship as partners evolved against the backdrop of an earlier shareholder dispute involving a third principal, Bernatchez, whose shares were ultimately bought out by the corporation, leaving Gaumond and Bournival as majority shareholders. After the Bernatchez dispute settled in November 2014, Gaumond, having successfully undergone cancer treatment, was expected to move toward retirement. By early 2015, the parties mandated an industry-recognized evaluator, Pronovost, to value Deslauriers, anticipating that Gaumond would sell all his shares to Bournival. Pronovost’s valuation as at 1 January 2015 applied a purchase multiple (coefficient) of 3.5 times commissions to determine the enterprise value, higher than the 2.5 multiple that had been used for the earlier Bernatchez buyout.

On the basis of this valuation, Bournival agreed to acquire all of Gaumond’s shares for a total price of $5,143,000. According to the Court, their conduct showed that an agreement on price and essential terms was reached in May 2015, when they accepted the valuation and coefficient without negotiation, relying on trust and a brief verbal confirmation, even symbolically sealed with a hug. For fiscal reasons, both knew that the transfer of Gaumond’s trust-held shares could only be completed after May 2016, given the two-year holding requirement to benefit from the capital gains exemption. In January 2016, Gaumond received provisional 2015 financial statements. He wanted to verify that the 2014-based valuation remained reasonable in light of 2015 results, but he did not communicate any condition delaying his consent. After reviewing the 2015 numbers, which showed slightly higher commissions, he expressly chose not to interrupt the sale process, thereby confirming the prior May 2015 agreement.

Parallel negotiations with the third-party buyer

While the internal buyout was being implemented, Bournival was also exploring a sale of his interest, including the shares to be acquired from Gaumond, to a third-party, Yan Charbonneau. Initial contact between Bournival and Charbonneau began around May 2015 but did not progress. Later, in December 2015, consultant André Moisan informed Bournival that he could find a buyer willing to pay a significantly higher multiple—4.5 times commissions—for Deslauriers. Communications concerning this potential sale were intentionally routed through personal email addresses for Bournival and his close associate, Leblond, with the stated aim of preserving confidentiality. In February 2016, Moisan reported two potential buyers. Bournival rejected one known competitor and focused on Charbonneau. Charbonneau received detailed financial information and, by 10 February 2016, indicated his firm intention to proceed. The discussions crystallized around an acquisition of all of Bournival’s holdings (which would include the shares bought from Gaumond), at a multiple that was ultimately set at 4.35, still well above the 3.5 multiple agreed with Gaumond.

Throughout this period, Bournival did not disclose to Gaumond the existence, terms, or seriousness of Charbonneau’s purchase project. The court found it implausible that a multiple of 4.5 or 4.35 was ever revealed to Gaumond; had he known, he would likely have remembered and reacted. The formal offer for Charbonneau’s purchase of Bournival’s shares was signed by Bournival on 5 April 2016 and by Charbonneau on 15 May 2016, five days after a farewell event marking Gaumond’s departure from the firm. Financing from Northbridge was arranged only later, but the Court held that, despite Bournival’s claims, the absence of confirmed financing did not make the negotiations speculative—he had clearly committed to the sale prior to financing being secured.

Contract formation and absence of dol

A central legal issue was when the contract for the sale of Gaumond’s shares to Bournival was formed. Applying provisions on consent and contract formation under the Civil Code of Québec (notably articles 1385–1388 and 1708 C.c.Q.), the Court held that the essential elements of the sale—identification of the shares and the price based on the 3.5 multiple—were agreed in May 2015. The later drafting of written share purchase agreements and shareholder agreements in early 2016 did not delay the moment of formation; they merely formalized an already binding verbal agreement. Gaumond’s January 2016 review of the 2015 financial statements did not constitute a suspensive condition for the validity of the contract. He never communicated that his consent was conditional on those figures and, when he saw that revenues were slightly higher but not materially different, he decided to let the process continue as agreed.

On the claim of dol (fraudulent misrepresentation or concealment), Gaumond argued that his consent was vitiated because, at the time he confirmed the sale, Bournival was already in parallel discussions to resell all the shares—including Gaumond’s—to Charbonneau at a higher multiple. Dol can arise from silence or dishonest non-disclosure of material information that would have changed the other party’s decision to contract. However, the Court emphasized that the analysis of vice of consent must be made at the moment when the contract is formed. Because the sale contract was formed in May 2015, before substantive negotiations with Charbonneau began, the later secret discussions could not have vitiated consent that was already validly given. Even if January 2016 were considered, the judge found that Gaumond’s January confirmation merely ratified the earlier agreement at the same multiple and that, by that date, the Charbonneau negotiations, though underway, did not legally retroact to undermine the existing bargain. Consequently, the Court found that dol was not established and that Gaumond could not obtain nullity or a reduction of his obligation on this basis.

Breach of the duty of good faith and shareholder transparency

The Court then turned to the broader duty of good faith in contractual performance, building on jurisprudence such as the Supreme Court of Canada’s decision in Ponce, which applied to similar co-shareholder scenarios where one party secretly arranges a lucrative resale after buying out co-owners. Under articles 1375 and 1434 C.c.Q. and the unanimous shareholder agreements (2003 agreement and its 2016 replacement), shareholders, including Gaumond and Bournival, were required to disclose any intention to sell their interests and to act loyally, considering the interests of their co-shareholders. In this context, the judge concluded that Bournival knowingly withheld critical information about his negotiations with Charbonneau, including the higher valuation multiple, and deliberately channeled communications through private emails to avoid detection by Gaumond and the minority shareholders.

Applying the criteria drawn from Bail and Ponce, the Court found that: Bournival possessed material information (the higher multiple and serious purchase interest); that information would have been determinative for Gaumond; and it was not realistically accessible to him given his reasonable reliance on his long-time partner. The Court therefore held that Bournival failed to meet the standard of contractual good faith and loyalty. Nevertheless, the judge distinguished this case from Ponce because, unlike in Ponce, Gaumond had already consented to sell his shares on defined terms before the lucrative third-party negotiations arose. The absence of good faith in the later execution phase did not, in this factual setting, translate into a compensable claim for damages.

Prescription and the timing of Gaumond’s claim

Prescription (limitation) proved decisive. Gaumond filed his action in December 2019. To be timely under the three-year extinctive prescription period, his right of action must not have arisen before December 2016. The Court examined when he knew or, acting diligently, ought to have known of the alleged fault, damage, and causal link. Gaumond learned in the summer of 2016 that Bournival had sold to Charbonneau, but he testified that he did not then know the terms, including the multiple used, and did not ask. During this period, he also acted as trustee for the Bournival family trust, signing a “Décision des fiduciaires” in August 2016 authorizing the sale of the trust’s shares to Charbonneau’s company, a document that referenced a detailed “convention confirmatoire” he never requested. In September 2016, still as trustee, he signed a National Bank document confirming a sale of the trust’s shares for $4,800,000, which he retained in his records, again without seeking the underlying agreement that disclosed the 4.35 multiple.

According to Gaumond, he only learned the coefficient actually used for the Charbonneau transaction—4.35—during a New Year’s gathering at Bournival’s home on 1 January 2017. He testified that this discovery shocked him and his spouse and that they left the event abruptly. The Court accepted that this was the moment when he became fully aware of the scale of the resale and its potential impact on his own sale price. However, the judge also found that, by mid-2016, Gaumond knew a sale to Charbonneau had occurred, knew that the price must have been advantageous for Bournival (who was younger and had needed to keep working longer to afford retirement), and had in his hands trustee documents pointing to a substantial purchase price. A reasonably diligent person, especially one as experienced in business and corporate governance as Gaumond, should have requested and reviewed the confirmatory agreement well before January 2017. His choice not to inquire was characterized as a form of voluntary blindness, insufficient to postpone the start of prescription.

The Court concluded that Gaumond had not met his burden to show an impossibility to act or a justification for delaying his claim. As a result, the judge held that the three-year prescription period had expired before the action was commenced, making the claim time-barred independently of the other issues.

Causation and the hypothetical Charbonneau sale

Even if prescription and dol had been resolved in Gaumond’s favour, the Court found the causal link between Bournival’s wrongful concealment and the specific damages claimed to be lacking. Gaumond insisted that, had he been aware of the higher multiple, he would have sold his shares directly to Charbonneau on similar terms. However, the Charbonneau deal contained conditions materially different from the internal sale to Bournival. For Charbonneau’s purchase, the majority seller had to remain actively involved in the business for at least one additional year, at a fixed salary, and was subject to a 10% holdback of the purchase price tied to the effective transfer and retention of a significant book of business. In evidence, Gaumond consistently portrayed himself as seeking full retirement and unwilling to continue running the brokerage for a third-party buyer. The Court therefore found it improbable that he would have accepted these conditions, especially the extended work obligation and performance-based holdback. It also remained speculative whether Charbonneau would have agreed to a configuration where both Gaumond and Bournival sold under modified terms.

In Quebec law, where misconduct has deprived a party of evidence about what might have occurred, a rebuttable presumption may sometimes assist the plaintiff. Here, the Court held that any such presumption was rebutted: the record showed that Gaumond did not want to sell to a third-party buyer and did not wish to continue working, making it unlikely that he would have realized the same profit as Bournival under Charbonneau’s structure. Accordingly, the necessary causal connection between Bournival’s breach of good faith and the particular lost profit calculation advanced by Gaumond was not established.

Damages, expert evidence and final outcome

Gaumond’s amended claim sought $1,514,127 in damages, calculated as the difference between the price he actually received for all his holdings (approximately $3,515,045, at the 3.5 multiple) and the higher amount he would have obtained if his shares had been sold at a 4.35 multiple (about $5,029,172). The defence expert from Richter accepted the arithmetic of this differential, while attempting to argue via an adjusted EBITDA analysis that Gaumond had in fact been fairly compensated overall. The Court sustained an objection to the expert’s EBITDA-based section as irrelevant, since the actual negotiations had turned on revenue multiples, not EBITDA, and both sides had anchored their deals to the chosen “coefficient.” The basic damage figure itself was accepted as mathematically accurate but remained purely hypothetical in light of the judge’s findings on contract formation, absence of dol, prescription, and causation.

In the result, the Superior Court dismissed Gaumond’s claim in its entirety. Although it explicitly criticized Bournival’s lack of post-contractual good faith and transparency toward his long-time partner, these breaches did not translate into liability for the alleged lost profit. The Court also departed from the usual rule on costs: it rejected the plaintiff’s action but awarded no legal costs to the successful defendant, citing both the partial exclusion and limited utility of the defence expert evidence and the court’s finding that Bournival had not acted in good faith. The successful party is therefore the defendant, Robert Bournival, and no monetary damages, costs, or other amounts were ordered in his favour; the total financial award is effectively zero.
