Executive Summary: Key Legal and Evidentiary Issues

• Scope and effect of a transaction-quittance as a settlement contract under articles 2631–2633 C.c.Q., including its res judicata impact on prior procedural misconduct.
• Whether pre-transaction delays, failure to respect procedural deadlines, and non-production of undertakings could still ground a claim for damages after a global settlement for 110,000.00 $.
• Interpretation of article 342 C.p.c. on “manquements importants dans le déroulement de l’instance” and its function as a sanction for abusive or improper procedural conduct, not a mechanism to compensate loss.
• Assessment of the Defendant’s non-payment of the settlement amount: mere default on payment versus evidence of dilatory or bad-faith procedural strategy justifying sanctions.
• Evidentiary insufficiency regarding any post-transaction misconduct: absence of proof of maneuvers, delay tactics, or misuse of procedure comparable to precedents like Anglo Galleon International Shipping.
• Allocation of responsibility for professional (extrajudicial) fees, and confirmation that the plaintiff cannot unilaterally reopen or expand the settlement once homologation is sought, absent an express contractual reservation.

Facts and procedural background

Gestion OPP inc. acted as contractor, performing construction work and supplying materials at the request of 9166-9929 Québec inc. on an immovable owned by the latter. The work was only partially paid. In response, Gestion OPP instituted proceedings on 6 November 2024 by filing a demand in forced surrender and sale under judicial control, seeking 230,779.35 $ and authorization to sell the improved immovable in order to recover its claim. As security, it had registered hypothecary rights against the property. During the main action, the Defendant contested the claim. Gestion OPP examined the Defendant’s representative out of court, and several case management conferences became necessary. The plaintiff had difficulty obtaining the undertakings promised by the Defendant’s representative during the pre-trial examination, leading to delays and management orders to move the file forward. On 1 October 2025, in dealing with a request to extend the inscription-for-trial deadline, the Superior Court (Dallaire J.C.S.) expressly warned that the Defendant’s failure to fulfill its disclosure undertakings exposed it to sanctions for serious misconduct in the conduct of the proceedings, potentially including an award of damages and interest. Against this procedural and evidentiary backdrop, the parties chose negotiation over further litigation. On 1 and 12 December 2025, they entered into a written “transaction-quittance,” a settlement intended to resolve fully and finally their dispute arising from the construction work and related judicial proceedings.

The settlement (transaction-quittance) and its terms

Under the transaction-quittance, 9166-9929 Québec inc. agreed to pay 110,000.00 $ to Gestion OPP inc. in capital, interest and costs, as a complete, final and definitive settlement of the dispute. Payment was to be made within ten days of signing the transaction. In return, Gestion OPP undertook, at its own expense, to discharge and strike all hypothecary rights it had published against the immovable within ten days of receiving payment. The parties also provided for mutual releases—each giving the other a broad quittance in relation to all claims, rights and recourses arising directly or indirectly from the facts alleged and the court file number associated with the original construction dispute and the immovable. Importantly, the settlement was expressly framed as a transaction within the meaning of articles 2631 and following of the Civil Code of Québec. As such, it was indivisible as to its object and, between the parties, carried the authority of res judicata once formed. The parties further stipulated that, if either party defaulted on its obligations, the transaction could be homologated by the court to make it enforceable and allow for forced execution.

Failure to pay and the new damages application

Despite the settlement, 9166-9929 Québec inc. did not pay the 110,000.00 $ within the agreed period and, by the time of the later proceedings, had still not remitted any amount to Gestion OPP. On 8 January 2026, while still awaiting payment, the Plaintiff launched a new application. In that application, later amended on 19 February 2026, Gestion OPP sought, among other things, 5,000.00 $ from the Defendant as compensation for professional fees and disbursements allegedly caused by the Defendant’s conduct. Initially, the Plaintiff grounded this claim on both the abuse-of-right provisions (articles 51 and following C.p.c.) and article 342 C.p.c., which deals with sanctions for serious misconduct in the conduct of litigation. During the hearing, however, counsel for Gestion OPP narrowed the legal basis, indicating that the claim for reimbursement of professional fees was pursued solely under article 342 C.p.c. The Defendant acknowledged having been slow and remiss in fulfilling its undertakings from the 28 May 2025 examination and in meeting procedural deadlines. It accepted that this had delayed the progress of the case and forced the Plaintiff to file case management notices and requests for extensions of time. Nevertheless, the Defendant argued that these issues had been captured and settled within the transaction-quittance, which was intended to resolve all legal and judicial consequences of the dispute, including any claims arising from its previous procedural shortcomings.

Contractual interpretation and res judicata effect of the transaction

The Court first examined whether Gestion OPP could still seek damages under article 342 C.p.c. for pre-settlement conduct, given the signed transaction-quittance. Applying articles 2631–2633 C.c.Q., the judge emphasized that a transaction is a contract by which parties terminate a dispute or prevent one from arising through reciprocal concessions, and that it has, between the parties, the authority of res judicata. The settlement clearly stated that the payment of 110,000.00 $, in capital, interest and costs, was in full, final and definitive settlement of the litigation. The Court noted that the “disputable” conduct—delay in disclosing undertakings, failure to respect procedural deadlines, and related case management difficulties—had all occurred before the December 2025 transaction and had even been expressly flagged by the Court in October 2025 as potentially sanctionable. When the parties later declared in their transaction-quittance that they wished to settle “all legal and judicial consequences” of the facts alleged and to end the litigation amicably to avoid the inconveniences of a trial, they necessarily included within that global settlement any claim tied to such procedural missteps. There was no clause reserving to the Plaintiff the right to claim separate damages under article 342 C.p.c. for pre-transaction misconduct should payment not be made. The judge stressed that Gestion OPP could not unilaterally add to or modify the settlement: in the face of non-payment, its recourse was to seek homologation and enforcement of the transaction, not to revive its original claims or tack on a new damages demand for the same underlying conduct.

Effect of non-payment on the transaction

The Plaintiff advanced the idea that the mutual releases and full quittance were conditional upon each party’s performance of its undertakings, notably the Defendant’s payment of 110,000.00 $. The Court accepted that the releases were tied to performance, but rejected the conclusion that non-payment extinguished the transaction or allowed the Plaintiff to reopen the merits or expand the settlement’s scope. Relying on established jurisprudence concerning the durability of transactions despite default, the judge held that the agreement remained in force; non-payment did not nullify it automatically. Instead, standard contractual principles applied: interpretation must seek the common intention of the parties. Here, reading the clauses as a whole, the Court found no indication that the parties intended that default would dissolve the settlement and permit a return to full-blown litigation on all underlying claims and alleged procedural misconduct. Rather, they had foreseen that, in the event of default, the appropriate mechanism was court homologation of the transaction to make it enforceable, enabling the creditor to execute against the debtor’s property. The Court also took note that Gestion OPP itself accepted homologation of the transaction, which confirmed that it recognized the Defendant’s financial responsibility as being confined to the already-agreed sum of 110,000.00 $, plus any applicable interest from the date of exigibility under article 1617 C.c.Q., and not an enlarged set of damages claims.

Application of article 342 C.p.c. to post-transaction conduct

On the second branch of its claim, Gestion OPP argued that it was entitled under article 342 C.p.c. to recover its professional fees incurred after the December 2025 transaction because of the Defendant’s refusal or failure to pay the settlement amount. The Court framed article 342 C.p.c. as a provision aimed at discouraging misuse of judicial procedure by sanctioning serious misconduct in the conduct of an instance. It is concerned with a party’s procedural behaviour, not its substantive position on the merits or mere breach of a substantive obligation. With that lens, the judge examined the evidence of the Defendant’s conduct after the settlement. The Plaintiff had proved only one fact: the Defendant did not pay the 110,000.00 $ as agreed. However, Gestion OPP did not allege or demonstrate any concrete dilatory tactics, obstruction, stalling maneuvers, or bad-faith strategies in the judicial process linked to the non-payment. There was no evidence that the Defendant ignored the court, refused to participate, or deliberately used procedure to avoid or endlessly postpone enforcement of the transaction.

Comparison with Anglo Galleon International Shipping and other precedents

The Plaintiff relied on the Superior Court decision in Anglo Galleon International Shipping as an illustration of how article 342 C.p.c. can be used to sanction a party that fails to honour a settlement. In that case, the defaulting party had ceased to cooperate entirely after announcing a transaction, failed to respond to multiple communications, and did not even appear at the hearing on the motion to homologate the transaction. The court there had a solid evidentiary basis to find a pattern of dilatory, obstructive, and bad-faith conduct amounting to serious misconduct in the conduct of the proceedings, justifying a sanction. By contrast, in the present case, the evidence did not show comparable behaviour. Beyond the simple fact of non-payment, there was no proof that 9166-9929 Québec inc. had maneuvered to delay or avoid enforcement, or that it had disengaged from the process. In fact, the Defendant itself took steps to prepare and present the motion for homologation of the settlement, which the Court took as a strong indicator that it was not using the procedure as a shield or as a tool of abuse. In this evidentiary context, the judge found it impossible to conclude that the Defendant’s non-payment, standing alone, constituted “manquements importants dans le déroulement de l’instance” within the meaning of article 342 C.p.c.

Outcome and financial consequences

In the end, the Superior Court dismissed Gestion OPP inc.’s amended claim for damages, which sought reimbursement of extrajudicial professional fees allegedly caused by serious procedural misconduct by 9166-9929 Québec inc. The Court held that (1) any claim related to the Defendant’s pre-transaction procedural failings had been absorbed and settled by the December 2025 transaction-quittance, which had res judicata effect between the parties; and (2) the Plaintiff had not proven the kind of post-transaction procedural abuse or serious misconduct required under article 342 C.p.c., as non-payment alone did not suffice. The Court rejected the damages claim in its entirety and did so without awarding legal costs, ordering that the application be dismissed “sans frais de justice.” In this specific judgment, the successful party is therefore 9166-9929 Québec inc., and no monetary award, costs, or damages were granted or ordered in its favor or in favor of Gestion OPP inc.; the total amount ordered in favor of the successful party is 0 $, with the settlement sum of 110,000.00 $ remaining a matter of contractual enforcement rather than a quantified judicial award in this decision.
