Executive Summary: Key Legal and Evidentiary Issues

• Dematic Limited appealed a Superior Court judgment homologating a settlement it had reached with SSENSE (17667884 Canada Inc., formerly Atallah Group Inc.).
   
• Central to the dispute was whether an August 2025 email exchange between the parties' representatives constituted a binding transaction under Quebec civil law.
   
• The Appellant argued that SSENSE's concealment of its insolvency during settlement talks vitiated its consent to the agreement.
   
• Quebec's Court of Appeal applied the palpable and overriding error standard to the trial judge's factual findings on the parties' intentions.
   
• Good faith obligations under the Supreme Court's rulings in Bail and Ponce were examined to determine whether SSENSE owed Dematic a duty to disclose its financial distress.
   
• Ultimately, the appellate court found no reviewable error and dismissed the appeal with legal costs against Dematic.
   

Facts of the case

Dematic Limited, a U.S.-headquartered supply chain automation engineering firm, entered into a Master Agreement with 17667884 Canada Inc. (formerly Atallah Group Inc.), which conducts business under the trade name SSENSE, in November 2020 for a $40 million project to upgrade SSENSE's Montreal-based order fulfilment centre. The parties later entered a Resident Maintenance Agreement (2022) and a Remote Support and Managed Services Agreement (2025). Dematic never fully implemented the fulfilment system as promised, and settlement discussions began in February 2025. Between August 26 and 27, 2025, Dematic's president, Michael Larsson, and SSENSE's chief operating officer, Bassel Atallah, exchanged emails in which Larsson offered a $10 million cash transfer, waiver of unpaid invoices, waiver of a final $2 million project payment, and waiver of certain service fees; Atallah accepted these terms the following day. Shortly afterward, on August 27, 2025, SSENSE's lender notified it of CCAA-related proceedings, and SSENSE obtained an initial order under the Companies' Creditors Arrangement Act on September 12, 2025. SSENSE had been insolvent since June 2025, a fact it never disclosed to Dematic during the settlement talks. When SSENSE later sought to formalize the settlement in writing, Dematic refused to sign, arguing no binding agreement had been reached and that SSENSE had negotiated in bad faith.

Policy and legislative provisions at issue

The case turned on Quebec's rules governing transactions (settlements) under the Civil Code of Québec. Article 2631 C.C.Q. requires three conditions for a valid transaction: a litigious dispute, an agreement not to pursue legal recourse, and mutual concessions. Article 2633 C.C.Q. gives a homologated transaction the authority of res judicata, meaning it becomes enforceable like a judgment once approved by the court. Article 1434 C.C.Q., concerning implicit contractual obligations arising from the nature of a contract, usage, or equity, was also considered in connection with a possible duty to disclose financial information. The Master Agreement's "Bankruptcy" clause, permitting either party to terminate on the other's insolvency, was central to Dematic's argument that SSENSE had an implied duty to disclose its financial state. The court also applied the good-faith framework from Bank of Montreal v. Bail Ltée and the Supreme Court's more recent decision in Ponce v. Société d'investissements Rhéaume ltée, which distinguishes the more limited good-faith duties owed under "exchange contracts" from the heightened obligations arising in long-term "cooperation contracts."

Reasoning and analysis

The Court of Appeal, in reasons authored by Schrager, J.A., found no error in the trial judge's conclusion that the parties reached a meeting of the minds on all essential elements of the transaction through the Email Exchange. Larsson's August 26 email did not make execution of a formal written agreement a condition of the deal, and while both parties, as experienced business people, may have expected a written memorandum to follow, this expectation did not undermine the binding nature of the email agreement itself. The court agreed that a mutual release was an essential element of the transaction, since SSENSE's release of claims against Dematic was the reason Dematic agreed to pay under the settlement, while other matters, such as payment timing and handling of spare parts, were secondary terms. On the disclosure issue, the court held that the relationship between Dematic and SSENSE was an exchange contract rather than a cooperation contract, since the parties had no common long-term enterprise; SSENSE simply purchased goods and services from Dematic under an agreement either party could terminate. The Master Agreement's bankruptcy-termination clause did not, by itself, create a duty for SSENSE to proactively disclose insolvency during settlement talks concerning a separate, retrospective contractual dispute. Applying the Bail framework, the court further found that SSENSE's financial condition was not of decisive importance to Dematic's decision to settle, since SSENSE was not the party paying under the transaction, and nothing in the Email Exchange suggested Dematic considered SSENSE's solvency material to the bargain.

Ruling and overall outcome

The Court of Appeal dismissed Dematic's appeal in its entirety, upholding the Superior Court's homologation of the settlement transaction between Dematic and SSENSE. The Respondent, 17667884 Canada Inc. (SSENSE), was the successful party. Legal costs of the appeal were awarded against Dematic, though the judgment does not specify a quantified amount for those costs. Separately, the underlying settlement homologated by the courts obliges Dematic to pay SSENSE $10 million in cash and to waive a $2 million final project payment along with certain other service fees, as set out in the Email Exchange.
