In Mohawk Council of Kanesatake v Sylvestre, 2025 SCC 30 (“Kanesatake”) the Supreme Court of Canada considered whether an unsuccessful attempt to execute a judgment can interrupt an extinctive prescription under Quebec civil law. The case arose after creditors filed and served a notice of execution against the Mohawk Council of Kanesatake but ultimately seized no property because the bailiff believed that the debtor’s property was exempt from seizure. Writing for a unanimous Court, Kasirer J. held that the notice of execution nonetheless interrupted prescription. The decision clarifies the relationship between the Civil Code of Québec (“CCQ”) and the Code of Civil Procedure (“CCP”), and confirms that creditor diligence, rather than the technical success of enforcement measures, lies at the heart of the law of prescription.
Facts
The Mohawk Council of Kanesatake is the governing body of the Mohawks of Kanesatake. Between 2001 and 2003, the Council retained several professionals, including lawyer Louis-Victor Sylvestre and various experts, to provide services in connection with the Council’s opposition to a proposed mining project. Some of those services went unpaid (Kanesatake, paras 12-13).
During this period, the Kanesatake experienced significant political and financial instability, and the Council’s affairs were temporarily placed under third-party management. These financial difficulties contributed to the Council’s failure to satisfy the debts owed to the respondents (Kanesatake, para 14).
On October 26, 2004, the respondents obtained two default judgments against the Council in the Superior Court of Quebec for unpaid professional fees. Sylvestre was awarded $536,771.47, while the other respondents were awarded $162,686.78, both amounts bearing interest (Kanesatake, para 15). Although the Council’s third-party manager later proposed a discounted settlement to resolve various debts, the respondents declined the offer (Kanesatake, para 15).
The respondents subsequently made several attempts to execute the judgments. These efforts initially interrupted prescription. In 2008, the Council acknowledged the debt and renounced the benefit of prescription that had elapsed in relation to Sylvestre’s claim (Kanesatake, para 16).
Years later, the judgments remained unpaid. On October 24, 2016, the respondents sought to execute the judgments by instructing a bailiff to seize the Council’s property. The bailiff filed a notice of execution with the Superior Court and subsequently served it on the Council and several potential garnishees (Kanesatake, paras 17-18).
When the bailiff attended the Council’s premises, he requested payment but ultimately did not seize any property because he believed the Council’s assets were exempt from seizure under the Indian Act. (Kanesatake, paras 19-20).
The Council later sought a declaratory judgment that the respondents’ claims had prescribed. It argued that the respondents’ unsuccessful attempt to execute the judgments in 2016 did not interrupt the 10-year prescription period. Both the Superior Court and the Court of Appeal rejected this argument, holding that prescription had been interrupted. The Council then appealed to the Supreme Court of Canada (Kanesatake, paras 25-26).
Judicial History
Superior Court of Quebec
The Superior Court dismissed the Council’s application for a declaratory judgment and concluded that the respondents’ claims had not prescribed (Kanesatake, para 27). In reaching this decision, the Superior Court held that prescription was interrupted when the notice of execution was filed and served on the Council in November 2016 (Kanesatake, paras 27).
The court emphasized that under article 2892 of the CCQ,prescription is interrupted when a creditor exercises its right through a judicial application, including a seizure (Kanesatake, para 30). This may be the case even if the seizure ultimately proves unsuccessful, because the creditor demonstrated diligence in pursuing its claim (Kanesatake, paras 31-32).
The judge rejected the Council’s argument that the absence of a completed seizure prevented interruption. An unsuccessful seizure is not equivalent to a dismissed judicial application. Accordingly, the respondents’ efforts to execute the judgment were sufficient to interrupt prescription (Kanesatake, paras 31-32).
However, the court held that the seizures by garnishment directed at third parties did not interrupt prescription because those measures had been annulled in earlier proceedings. In contrast, the attempted seizure of the Council’s own property remained a valid judicial application that interrupted prescription (Kanesatake, para 35).
Court of Appeal of Quebec
The Court of Appeal unanimously dismissed the Council’s appeal. It agreed that prescription had been interrupted by the filing and service of the notice of execution, even though the seizure itself was unsuccessful (Kanesatake, para 37).
The Court of Appeal also held that the bailiff was not required to prepare minutes of seizure where no property was actually seized. Because the seizure did not proceed, the absence of such minutes did not invalidate the execution process (Kanesatake, paras 38-39).
Finally, the Court of Appeal confirmed that an unsuccessful seizure cannot be treated as a dismissed judicial application for the purposes of article 2894 of the CCQ. Since the respondents had clearly demonstrated their intention to enforce the judgments, prescription had been interrupted (Kanesatake, para 40).
Issues
The Supreme Court framed the dispute around three central questions:
- Did the filing and service of the notice of execution interrupt prescription under article 2892 of the CCQ? (Kanesatake, paras 43)
- If the notice of execution initially interrupted prescription, was that interruption retroactively nullified under article 2894 of the CCQ because the attempted seizure was unsuccessful? (Kanesatake, paras 44)
- Did s. 89 of the Indian Act, which protects certain property on reserve from seizure, affect the analysis in this case? (Kanesatake, paras 42-46)
Background
The appeal required the Court to interpret Quebec’s law of extinctive prescription in the context of the forced execution of judgments. Loosely comparable to Ontario’s statute of limitations, the law of extinctive prescription extinguishes a right if that right is not exercise within a set time limit. Under article 2924 of the CCQ, a right resulting from a judgment prescribes if the creditor does not exercise the right within ten years (Kanesatake, para 47).
Prescription may be interrupted when a creditor files a judicial application before the prescriptive period expires and serves it within the required time limits. Article 2892 of the CCQ expressly provides that seizures are considered judicial applications capable of interrupting prescription (Kanesatake, para 48).
When prescription is interrupted, the prescriptive period begins to run anew. However, article 2894 of the CCQ states that interruption does not occur if the judicial application is dismissed, discontinued, or pre-empted (Kanesatake, paras 49).
The case also required the Court to consider the procedural framework governing the execution of judgments under the CCP. Under this regime, forced execution begins when a bailiff files a notice of execution with the court and serves it on the debtor (Kanesatake, para 53). The notice sets out the judgment to be enforced and describes the execution measures to be taken.
Importantly, both the Civil Code and the Code of Civil Procedure are interpreted as coordinated civil law codes that must be read together. The Court emphasized that the rules governing prescription and the rules governing execution of judgments form part of a coherent legal framework (Kanesatake, paras 57-58).
Decision
The Supreme Court dismissed the appeal and held that the respondents’ claims had not prescribed.
Issue 1: Did the notice of execution interrupt prescription?
The Court held that the filing and service of the notice of execution constituted a judicial application for seizure capable of interrupting prescription under article 2892 of the CCQ. The notice of execution is not merely a preliminary step; rather, it initiates the seizure process and therefore forms part of the judicial application itself (Kanesatake, paras 73-75).
Because the respondents filed and served the notice within the prescriptive period, they took concrete steps to exercise their rights under the judgments. This demonstrated the diligence required to interrupt prescription (Kanesatake, paras 76, 103).
Issue 2: Was the interruption retroactively nullified?
The Court rejected the argument that the interruption of prescription was retroactively nullified under article 2894 of the CCQ. Although the attempted seizure ultimately proved unsuccessful, the judicial application had not been dismissed by a court. Instead, the bailiff merely suspended the execution after determining that no seizable property was available (Kanesatake, paras 92-94).
An unsuccessful seizure is not equivalent to a dismissed judicial application. Because the respondents had taken concrete steps to enforce their rights, prescription remained interrupted (Kanesatake, para 96).
Issue 3: Did the Indian Act affect the analysis?
The Court ultimately declined to decide whether the Council’s property was protected from seizure under s. 89 of the Indian Act. It held that the case could be resolved entirely through the interpretation of the Civil Code and the Code of Civil Procedure, making it unnecessary to address the statutory immunity issue (Kanesatake, para 46).
In the result, the Court concluded that the respondents’ 2016 notice of execution validly interrupted prescription, and the Council remained liable for the outstanding judgment debts.
Analysis
A central theme in Kanesatake is the Court’s effort to align the law of prescription with the modern procedural framework governing the execution of judgments. At its core, the decision clarifies that the filing and service of a notice of execution can interrupt prescription even if the attempted seizure ultimately proves unsuccessful.
By recognizing the notice of execution as part of the judicial application for seizure, the Court places emphasis on creditor diligence rather than the technical success of the enforcement measure (Kanesatake, paras 73-75). This approach reflects the underlying purpose of extinctive prescription. As the Court explains, prescription is meant to sanction a creditor’s failure to act on their rights within the prescribed time period. Where a creditor takes concrete steps to enforce a judgment, the rationale for prescription largely disappears (Kanesatake, para 76). In this sense, the notice of execution operates as a clear signal that the creditor intends to pursue the claim. The filing and service of that notice therefore provide a reliable indicator of diligence, which justifies interrupting the prescription period.
The Court’s reasoning also reflects the broader procedural reforms that shaped Quebec’s current civil justice system. Under the former regime, execution of judgments often required a writ of execution issued by the court. The modern Code of Civil Procedure replaced that formal mechanism with the simpler notice of execution, which allows creditors to initiate enforcement through a bailiff without first obtaining judicial authorization (Kanesatake, para 83). This reform aimed to reduce procedural complexity and make the enforcement process more efficient. In recognizing the notice of execution rather than the successful execution as the act that interrupts prescription, the Court reinforces that shift toward a more practical and streamlined system of civil justice.
Another important aspect of the decision is the Court’s distinction between an unsuccessful seizure and a dismissed judicial application. Article 2894 of the CCQ provides that interruption of prescription does not occur where the judicial application is dismissed. The appellant argued that because the seizure ultimately failed, the interruptive effect of the notice should be retroactively nullified. The Court rejected this argument, holding that a judicial application is only “dismissed” where a court formally rejects the claim. In this case, the bailiff simply suspended the execution process after determining that no seizable property was available (Kanesatake, paras 92-96).
This distinction is significant because it preserves the practical function of enforcement proceedings. If an unsuccessful seizure were treated as equivalent to a dismissed judicial application, creditors would risk losing their rights whenever enforcement efforts proved temporarily ineffective. Such a rule could allow debtors to avoid liability simply by ensuring that their assets were unavailable or exempt from seizure at the time enforcement was attempted (Kanesatake, paras 97-98). By refusing to adopt this interpretation, the Court ensures that the existence of a debt remains distinct from the immediate availability of assets to satisfy it.
Viewed more broadly, the decision promotes a balanced approach to prescription and enforcement. Creditors must still take timely steps to enforce their rights, but they are not penalized simply because an enforcement attempt fails. At the same time, debtors remain protected by the procedural safeguards built into the execution process, including the ability to challenge abusive or improper enforcement measures. In this way, Kanesatake reinforces a practical understanding of prescription that reflects both the purpose of the doctrine and the realities of modern civil procedure.
