Executive Summary: Key Legal and Evidentiary Issues

• Laurent Chebanier and Stéphanie Chebanier purchased a condominium from Lorenzo Priolo on December 7, 2021, only to discover a major water infiltration defect affecting the building envelope approximately two months after closing.
• Special assessments totalling over $45,000 for their unit were linked to the defect, with confirmed payments of $15,013 in 2022, $7,730 in 2023, and $13,407 in 2024.
• Central to the dispute is whether the defect constituted a latent (hidden) defect under the legal warranty of quality provided in the Civil Code of Québec, triggering the seller's liability.
• Priolo failed to disclose relevant minutes of meetings and an expert report predating the sale, though the court found he acted without bad faith — only negligence.
• Claims against the real estate broker Matthew De Angelis, his corporate employer 9336-6227 Québec inc., and the Syndicat de la Copropriété Le 3351 Masson were dismissed for insufficient proof of fault.
• Confusion arose because the vendor's declaration referenced a separate, minor water infiltration issue already addressed, leading buyers to reasonably conflate it with the undisclosed major problem.

Facts of the case

On December 7, 2021, Laurent Chebanier and Stéphanie Chebanier (the buyers) purchased a condominium unit within the co-ownership property at 3351 Masson from Lorenzo Priolo, with the benefit of a legal warranty. During the transaction, Priolo was represented by real estate broker Matthew De Angelis, operating through 9336-6227 Québec inc. The buyers conducted the verifications they considered necessary and believed they were acquiring a property in good condition with no major expenses anticipated.

Approximately two months after the purchase, the buyers learned of a significant water infiltration problem affecting the building envelope — a defect that had not been resolved. This prompted them to realize that a special assessment of over $45,000 applied to their unit in connection with the problem. They confirmed at the hearing that they had paid special assessments of $15,013 in 2022, $7,730 in 2023, and $13,407 in 2024 related to these defects. The total cost of remediation for the entire building was subsequently estimated at approximately $685,000. The buyers argued that all defendants either knew of the problem or had access to relevant information and failed to disclose it despite being asked. They sought $15,000 — a figure reduced to fall within the Small Claims Division's jurisdiction.

Legal framework and contractual provisions at issue

The court applied the legal warranty of quality under Article 1726 of the Civil Code of Québec, which obliges a seller to guarantee that the property is, at the time of sale, free of latent defects that render it unfit for its intended use or that diminish its utility to the extent that the buyer would not have purchased it, or would not have paid so high a price, had the defects been known. The seller is not required to warrant a defect known to the buyer, nor one that is apparent — meaning one that a prudent and diligent buyer could discover without an expert. The court also applied the general fault-based liability framework under Article 1457 of the Civil Code, requiring the buyers to establish fault, damage, and a causal link.

Reasoning and analysis

The court was satisfied that the defect qualified as a latent defect: it was serious, unknown to the buyers at the time of purchase, and gave rise to very significant financial consequences. Priolo's vendor declaration, dated October 8, 2021, made no reference to the water infiltration problem at the building envelope. He also failed to provide the buyers with the minutes of the June 1, 2021 and March 9, 2021 meetings, both of which addressed the issue, and withheld the expert report dated August 17, 2021. The buyers had specifically requested all available minutes but received a different set, leaving them with a reasonable belief that they had everything they needed to make an informed decision. The court acknowledged that Priolo did not act in bad faith, but found that he was negligent in failing to acquaint himself with pertinent information about his own property and communicate it to prospective buyers.

As for the other defendants, the court rejected the claims for insufficient evidence. The broker relied on information provided by Priolo after confirming with him that all available information had been shared. The Syndicat de la Copropriété did respond to the notary's information request and mentioned the existence of a water infiltration problem. However, because the vendor's declaration separately referenced a minor, already-remedied water infiltration issue, the buyers reasonably understood the syndicat's reference to concern the same minor matter. At the time of the transaction, the syndicat had also confirmed that all special assessments for 2021 had been paid and that no additional amounts were outstanding — a response that was accurate at the time, as the cost of repairs had not yet been determined and no special assessments relating to the envelope defect had yet been levied. The court noted that while more rigorous practices by the other defendants could have alerted the buyers to the problem, this fell short of actionable fault.

Ruling and overall outcome

The court allowed the claim against Lorenzo Priolo and dismissed all claims against the remaining defendants without costs — noting that, despite the absence of fault on their part, more thorough disclosure practices could have prevented the situation. Priolo was ordered to pay Laurent Chebanier and Stéphanie Chebanier the sum of $15,000, together with interest at the legal rate and the additional indemnity under Article 1619 of the Civil Code of Québec, running from July 16, 2022, plus court costs of $230 representing the judicial stamp on the claim.
