Executive Summary: Key Legal and Evidentiary Issues

• Standing under article 3061 C.c.Q. was established, as the former owner of the immovable qualified as an "interested person" entitled to seek cancellation of the legal hypothec.
• Registration of the construction legal hypothec occurred on September 12, 2025, which was 42 days after the end of the works (July 31, 2025 at the latest), exceeding the 30-day deadline under article 2727 C.c.Q.
• No prior notice of exercise of a hypothecary right was published, and no conservatory action was published within six months of the end of the works.
• Deadlines under article 2727 C.c.Q. are forfeiture deadlines (délais de déchéance), so their non-compliance is fatal and the court cannot relieve a party from default.
• Sworn declarations of the new owners, listing photos from April 2025, and Darveau's pre-trial examination established that the renovation works were completed and the house was habitable.
• Maintaining the hypothec despite the expired deadlines, advancing unfounded arguments, and filing the defence and counterclaim six months late constituted an abuse of procedure under article 51 C.p.c.

Facts of the case

The plaintiff, 6967337 Canada inc., is the former owner of a residence in the land registration division of Deux-Montagnes. The defendant, Les Habitations Darveau inc., is held by Jonathan Darveau, who was in a relationship with the daughter of the plaintiff's owner. Darveau carried out renovation works at the residence with the intention of living there and ultimately purchasing it, and he lived in the house from July 22, 2022 until July 2025. The couple separated, and Darveau did not have the means to finance the purchase of the house. On August 18, 2025, Sandrine Bourgon and Sébastien Lajoie, a couple with no connection to the other parties, bought the house and moved in. On September 12, 2025, the defendant registered a legal hypothec on the immovable, in an amount of more than $229,950. The plaintiff brought a demand for a declaration of foreclosure, abuse, and cancellation (radiation) of the legal hypothec. The defendant's defence and counterclaim, claiming $229,950, was notified and filed on June 18, 2026 — the eve of the hearing — even though the case protocol signed on November 17, 2025 required it by December 19, 2025.

Statutory provisions at issue

Three provisions of the Civil Code of Québec were central. Article 2726 C.c.Q. provides that the legal hypothec in favour of persons having taken part in the construction or renovation of an immovable exists without publication, in favour of the architect, engineer, supplier of materials, workman, contractor or subcontractor, for work requested by the owner. Article 2727 C.c.Q. sets out two preservation formalities within strict timeframes: the hypothec subsists for 30 days after the end of the works and is preserved only if, before that period expires, a notice designating the charged immovable and indicating the amount of the claim is registered and served on the owner; it is then extinguished six months after the end of the works unless the creditor publishes an action against the owner or registers a prior notice of the exercise of a hypothecary right. Article 3061 C.c.Q. allows "any interested person" to apply for cancellation of the registration where, within six months of the registration or the end of the works, no action has been instituted and published and no prior notice has been published. The plaintiff also relied on articles 51 and following of the Code of Civil Procedure governing abuse of procedure, and the sale contract was relevant: the plaintiff had undertaken to deliver clear title to the new owners, and the deed of sale stated that any unpaid repairs would have to be paid by the vendor at its expense.

The court's reasoning and analysis

Justice Eleni Yiannakis of the Superior Court first rejected the defendant's argument that the plaintiff lacked standing because it was no longer the owner when the hypothec was published. The words "any interested person" in article 3061 C.c.Q. are broad and do not require holding a real right; the plaintiff's contractual undertaking to deliver clear title, and its exposure to a recourse from the new owners, gave it sufficient interest. The court then determined the end of the works. Giving the defendant the benefit of the doubt, the latest possible date was July 31, 2025, when Darveau left the residence; sworn declarations of the new owners with listing photos displayed in April 2025 showed the renovations were finished and the house was habitable, apart from one moulding valued at $1,500 — about 0.6% of the hypothec amount — and Darveau's pre-trial examination supported this conclusion. Since the hypothec was registered on September 12, 2025, 42 days after the end of the works, the 30-day deadline was missed. No prior notice of exercise was ever published, and even treating the counterclaim as the required conservatory action, it was transmitted on June 18, 2026, some 11 months after the end of the works, well beyond the six-month deadline. These are forfeiture deadlines, so the impossibility-to-act argument was inadmissible and the court could not relieve the defendant of its default; the verbal request to be relieved from the default of filing the defence became moot. On abuse, the court found the defendant's position untenable: it argued its answer (appearance) to the cancellation demand of October 25, 2025 was a sufficient notice replacing the required formalities, without any supporting authority. Since March 2026 the plaintiff had informed Darveau, with authorities in support, that the failure was fatal, yet he persisted and forced a hearing on June 19, 2026 that could clearly have been avoided by voluntary cancellation, without prejudice to his right to sue in damages for amounts he claims are owed. The court noted it was not seized of, and did not rule on, the survival of the counterclaim, a damages claim being in principle independent of the fate of the legal hypothec notice.

Ruling and outcome

The court granted the demand for a declaration of abuse and cancellation of the hypothec, declared invalid and illegal the legal hypothec published on September 12, 2025 under number 29 741 825 against lot 1 691 404 of the cadastre of Québec, ordered the registrar of the Deux-Montagnes land registry office to proceed with the cancellation, and declared the maintenance of the registration abusive. The plaintiff, 6967337 Canada inc., thus prevailed entirely. Having produced its fee invoice totalling $10,522.92 (taxes included) for the preparation and hearing of the cancellation demand, it claimed $8,000, which the court found reasonable and justified: the defendant was ordered to pay the plaintiff $8,000 in lawyers' fees, the whole with legal costs (the amount of which is not specified in the judgment).
