Antoine Ponce, et al. v. Société d’investissements Rhéaume ltée, et al. (39931)

Posted on: 2023-01-12


The appellants, Mr. Ponce and Mr. Riopel, served as presidents of three companies grouped together under the name “Le Groupe Excellence” controlled by the respondent shareholders, Mr. Rhéaume and Mr. Beaulne. Rhéaume and Beaulne founded Excellence in the late 1970’s, but their working relationship ultimately broke down due to a revenue share dispute. A few years later, the appellants bought the respondents’ interests in Excellence. Rhéaume and Beaulne were unaware, however, that the appellants had been negotiating the sale of Excellence to a third party, Industrial Alliance. Shortly after acquiring the shares of Rhéaume and Beaulne, the appellants sold their interests in Excellence for a significant profit. The respondents allege that the sale of Excellence by the appellants stripped them of a business opportunity. They applied to the courts and claimed joint and several damages against the appellants. The Superior Court granted the respondents’ action in part. The court determined that the appellants used their roles to obtain information for their own benefit, and breached duties of good faith, integrity and loyalty owing to Rhéaume and Beaulne as shareholders. The Court of Appeal dismissed the appellants’ appeal. Although it found that the trial judge made an error in determining that the duty of loyalty was owed to the shareholders, as opposed to the corporation, this error was not determinative since the judge also relied on the obligation of good faith and the duty to inform to conclude that the appellants were at fault towards the respondents.
