Executive Summary: Key Legal and Evidentiary Issues

• Apportionment of liability between solidary co-debtors Riopel and Ponce following a Supreme Court of Canada judgment exceeding $11 million, after each paid 50% of the condemnation.
• Attempt by Ponce to bring his alleged liability insurer, Industrielle Alliance (IA), into the case by way of forced intervention and call in warranty based on liability coverage and section 56 of the former Loi sur les assurances.
• Assessment of whether there is sufficient connexity between the main action (allocation of solidary liability between Riopel and Ponce) and the proposed warranty action against IA to justify a single proceeding.
• Determination that a parallel action by Ponce against IA in another file (the “-225” Montreal dossier) already covers the same factual matrix, legal foundation and indemnity sought, creating litispendance.
• Application of civil procedure principles, including article 184 C.p.c. (forced intervention and call in warranty) and proportionality/efficient use of judicial resources, to refuse expansion of the present case into a broader insurance dispute.
• Evidentiary focus on the existing pleadings in the -225 action, including Ponce’s express reservation of the right to claim from IA any amount he might later be ordered to pay Riopel, which the Court treats as covering the same recourse he now seeks via call in warranty.

Background and facts of the dispute

The judgment in Riopel c. Ponce 2025 QCCS 4740 arises in the wake of a long and complex commercial dispute involving the sale of interests in Groupe Excellence to Industrielle Alliance, Assurance et services financiers inc. (IA). The original litigation, often referred to as the “Dossier Rhéaume-Beaulne,” culminated in a Supreme Court of Canada decision (Ponce c. Société d’investissements Rhéaume ltée) that confirmed a solidary condemnation against Daniel Riopel and Antoine Ponce, among others, in an amount exceeding $11 million, plus interest, additional indemnity and costs. That Supreme Court judgment did not determine the internal allocation of responsibility as between Riopel and Ponce under articles 1536 of the Civil Code of Québec and 328 of the Code of Civil Procedure, which govern recourse and contribution between solidary co-debtors. In the wake of that solidary condemnation, Riopel and Ponce each paid 50% of the amount owed. Riopel and his company, Société d’investissements Vodoo Ltée, then commenced a new action in February 2024 before the Superior Court of Québec seeking approximately $6 million from Ponce. Their theory is that, based on the findings made in the Rhéaume-Beaulne litigation and the value attributed to the parties’ respective interests in Groupe Excellence, Ponce should bear a higher share of the damages, and that Riopel therefore overpaid his true proportion of the solidary obligation. The present Terrebonne action is thus a contribution and adjustment suit between the solidary co-debtors, focused on the allocation of responsibility for the Supreme Court judgment.

Parallel insurance litigation against Industrielle Alliance

Even before the Supreme Court rendered its decision in the Rhéaume-Beaulne file, both Ponce and Riopel had initiated separate actions in Montreal against IA in March 2022 to recover their legal fees incurred on appeal in that earlier litigation. Those actions were joined, and in that context Riopel ultimately discontinued his claim against IA and instead opted to sue Ponce in the current Terrebonne file for contribution to the solidary judgment. Ponce, however, maintained his action against IA in the Montreal proceeding, now known under docket 500-17-120404-225 (the “-225” file). In that insurance action, Ponce alleges that IA was his liability insurer at the relevant time and that IA must reimburse his defence costs before the Quebec Court of Appeal and the Supreme Court of Canada, as well as the damages, judicial costs and expert fees he paid to satisfy the Rhéaume-Beaulne judgment. He further pleads that IA is obliged to assume his defence and indemnify him for any additional sums he may be ordered to pay in connection with his role in those underlying events.

Alleged insurance obligations and policy concepts at issue

Ponce’s claims against IA are grounded in the contention that IA acted as his “assureur-responsabilité” (liability insurer) during the period in which the facts giving rise to the Rhéaume-Beaulne litigation occurred. On this basis, Ponce argues that IA must “prendre fait et cause” for him (i.e., take up his defence) and indemnify him for any condemnation, invoking the structure of insurer’s obligations traditionally associated with liability policies and, specifically, section 56 of the former Loi sur les assurances. That statutory provision, in essence, required the insurer to assume and bear the damages that the insured would otherwise be required to pay if the loss fell within the contractual coverage. In the Terrebonne case, Ponce seeks to extend this framework to any future amount that he might be condemned to pay to Riopel as part of the internal allocation of the Supreme Court judgment. Although the judgment under review does not reproduce the actual policy wording, the operative legal concept is that of a liability policy under which the insurer not only covers defence costs but is also bound to satisfy judgments rendered against the insured for covered liabilities. Ponce’s position is that, if he is ultimately required to pay additional sums to Riopel beyond the 50% he has already contributed to the solidary judgment, those additional sums should be shifts in economic burden that IA must absorb under its alleged liability coverage.

The call in warranty and proposed forced intervention

In April 2024, within the Terrebonne contribution action, Ponce filed an Acte d’intervention forcée seeking to add IA as a defendant and to call the insurer in warranty. Initially framed as both a forced intervention and an appeal in warranty, the pleading was later clarified at the hearing—on the court’s authorization—to specify that it was solely an appeal in warranty, with the conclusions adjusted accordingly. In the Acte d’intervention, Ponce alleges a series of factual and legal grievances against IA. He recites IA’s involvement in the underlying Groupe Excellence transaction and its alleged role as liability insurer, and asserts that IA must both assume his defence and indemnify him from any condemnation that could be pronounced against him in the current Terrebonne proceeding. The strategy is procedural: rather than litigating his indemnity rights against IA strictly within the existing -225 insurance action, Ponce seeks to consolidate those issues into the Terrebonne file by formally bringing IA in as a third party by way of call in warranty. In response, both the plaintiffs (Riopel and Vodoo) and IA oppose the intervention. They argue that there is no sufficient connexity between the warranty claim and the main action on contribution, that the questions raised against IA are already fully before the court in the -225 file, and that allowing the intervention would substantially broaden and delay a relatively narrow dispute about allocation between two co-debtors.

Governing procedural principles for forced intervention and call in warranty

The Court’s analysis begins with article 184 of the Code of Civil Procedure, which governs intervention, both voluntary and forced. An intervention is “forcée” when a party brings a third person into the proceedings to ensure a complete solution of the dispute, to oppose the judgment to that third person, or to exercise a call in warranty. In the ordinary case, forced intervention results in the addition of a new defendant, and the link to be assessed is the legal connection between the person brought in and the principal plaintiff. As for the call in warranty, the Court underlines that it is a form of anticipated recourse in warranty: the defendant in the main action asks that a third party be condemned, if the defendant is held liable, to indemnify it for the condemnation it may suffer. For such a call in warranty to be admissible, two conditions must be met: first, there must be a sufficient legal link (lien de droit) between the party calling in warranty and the third-party guarantor; second, there must be a sufficient link of connexity between the main demand and the warranty claim, such that there is a real risk of contradictory judgments if the two actions proceed separately before different judges. The Court also invokes the overarching principles of the “nouveau” Code of Civil Procedure, especially proportionality and the sound administration of justice (art. 18 C.p.c.). Even if formal criteria for an intervention could be satisfied, a judge may, in the exercise of discretion, refuse a forced intervention that would unduly complicate or delay the main action, import a long and complex debate already being litigated elsewhere, or impose on the principal plaintiffs a dispute extending well beyond the scope of their own claim.

Connexity and the existence of parallel proceedings

Applying these principles, the Court first acknowledges that there is indeed a legal link between Ponce and IA: Ponce is already suing IA in the -225 file, and IA’s alleged obligations as liability insurer form the core of that existing action. What is contested is the second requirement—connexity between the Terrebonne main action and the proposed warranty claim. The main Terrebonne action is narrowly focused on the allocation of a solidary condemnation between Riopel and Ponce. The factual and legal issues center on how responsibility for the Supreme Court judgment should be apportioned internally based on the parties’ respective roles, benefits and contractual positions in the Groupe Excellence transaction. By contrast, the proposed call in warranty against IA raises questions about the scope of IA’s insurance obligations, the nature of its involvement in the original transaction, and the insurer’s duty to defend and indemnify Ponce for amounts he has already paid or may have to pay in the future. The Court finds that these questions are fundamentally distinct from those raised between Riopel and Ponce. Crucially, the judge concludes that any genuine risk of contradictory judgments lies not between the Terrebonne action and the proposed warranty claim, but between that warranty claim and the already pending -225 insurance action. In the -225 proceedings, Ponce is seeking reimbursement of his defence costs, damages, judicial costs and expert fees paid under the Rhéaume-Beaulne judgment, and has explicitly reserved his right to claim from IA any amount he may be ordered to pay in the contribution action brought by Riopel. This reservation is treated as encompassing the very same anticipated recourse Ponce is now trying to advance via the call in warranty. As a result, the Court accepts the argument that there is litispendance between the proposed warranty claim in Terrebonne and the -225 file: the same parties (Ponce and IA) are involved, the object of both proceedings is IA’s alleged obligation to assume Ponce’s defence and indemnify him for damages, and the cause of action in each rests on the same factual matrix and legal characterization. In these circumstances, the Court holds that the connexity requirement is not met vis-à-vis the Terrebonne main action, and that the duplication of proceedings against IA is procedurally improper.

Proportionality, case management and judicial economy

Beyond strict litispendance, the Court invokes proportionality and the effective management of judicial resources to reinforce its refusal of the intervention. The plaintiffs’ claim between Riopel and Ponce is, in the judge’s words, relatively circumscribed; the anticipated trial is expected to last about two days and to be limited to the apportionment of liability arising from the Supreme Court judgment. By contrast, importing the entire insurance and liability debate with IA into this proceeding would expand its scope significantly, introduce complex factual and legal issues already being litigated elsewhere, and inevitably delay the resolution of the plaintiffs’ comparatively narrow contribution action. The Court emphasizes that permitting such an intervention would change the orientation of the file, broaden the debate in a manifestly unnecessary way, and conflict with the procedural objective of facilitating the normal progression of trials rather than hindering them. Given that Ponce already has an action against IA on foot in the -225 file, and that he has reserved the right within that action to claim any amount he might later be ordered to pay to Riopel, there is no legitimate need to replicate or transplant that dispute into the Terrebonne contribution case.

Ruling and outcome, including the successful parties and monetary consequences

In the result, the Superior Court grants both sets of oppositions to the Acte d’intervention: the opposition filed by the plaintiffs Riopel and Société d’investissements Vodoo Ltée, and the opposition filed by Industrielle Alliance. The Court declares Ponce’s attempt to bring IA in as a third-party defendant by way of forced intervention and call in warranty to be inappropriate in light of the lack of connexity with the main action, the existence of litispendance with the -225 insurance proceedings, and the guiding principles of proportionality and sound judicial administration. The Acte d’intervention is therefore rejected, and the case is ordered to proceed strictly as between the original parties, with directions to file a new case protocol that reflects this procedural outcome. The judgment concludes with an award of “frais de justice” (court costs) in favour of the successful parties, namely Riopel, Société d’investissements Vodoo Ltée and Industrielle Alliance, and against Ponce. However, as is typical in Quebec practice, the reasons do not specify the exact quantum of those costs, which will follow the applicable tariff. No damages or indemnity amounts are ordered in this procedural ruling itself, so the total monetary award in favour of the successful parties cannot be determined from the text of this judgment.
