Executive Summary: Key Legal and Evidentiary Issues

• Identifying the general contractor of a 48-unit condominium built in 2005 required the court to weigh conflicting contemporaneous documents against decades-old, incomplete corporate records.
   
• Determining which trade — the air conditioning installer or the plumber — bore responsibility for an unconnected drainage pipe hinged on testimony distinguishing rough-in work from final plumbing connections.
   
• Assessing whether the water damage constituted a hidden defect under the legal warranty of quality turned on whether a buyer could reasonably have detected the flaw before purchase.
   
• Establishing subrogation rights required confirming the Syndicate's standing to sue as the party that indemnified the affected unit owner.
   
• Apportioning in solidum liability between two defendants held liable on distinct legal grounds required the court to invoke a specific procedural mechanism for allocating shares.
   
• Reconciling the parties' mutual finger-pointing among the general contractor, construction manager, and two subcontractors illustrated the evidentiary challenges of assigning fault for latent construction defects discovered years later.

Facts of the case

The Syndicat des copropriétaires Les Terrasses Maisonneuve sought $15,000 from Ogesco Construction inc. and Société immobilière Maisonneuve inc. after compensating a unit owner for water damage traced to a drainage pipe that had never been connected to a washer drain. The building, constructed in 2005, had been fitted in advance with drainage piping for units without air conditioning, so a future owner could add it without reopening the walls. In 2020, Société immobilière Maisonneuve inc., then owner of unit 109, hired Réfrigération Everest inc. to install a wall-mounted air conditioning unit; the technician connected the pipe's upper end to the new unit and assumed the lower end was already connected to the washer drain. It was not. Maisonneuve inc. sold the unit, with legal warranty of quality, to Lyne Roberge in October 2020. Roberge first ran the air conditioning during a July 2021 heat wave, and water seeped under the unit's floor, causing damage repaired at a cost of $22,382.34. Once the wall was opened, a photograph showed the drainage pipe's lower end hanging unconnected roughly 18 inches from the drain. The Syndicate, having indemnified Roberge, pursued Ogesco and Maisonneuve inc., who each blamed the other for having been general contractor, and who in turn sought to shift responsibility to the subcontractors: Everest, which had installed the air conditioning, and Plomberie J. Vachon inc., which had performed plumbing work during the original 2005 construction. Maisonneuve inc. called Everest in warranty, and Everest called Vachon inc. in warranty.

Policy and legislative provisions at issue

Several Civil Code of Québec provisions framed the dispute. Article 2124 C.C.Q., invoked by Ogesco, provides that a real estate developer who sells a work it built or had built is assimilated to the contractor — supporting Ogesco's position that Terrasses inc., not Ogesco, should bear a general contractor's obligations. Article 1726 C.C.Q. sets out the conditions for the legal warranty of quality: the defect must be hidden, unknown to the buyer, present at the time of sale, and sufficiently serious. Article 1074.2 C.C.Q. governs the Syndicate's subrogation to the rights of the member it indemnified, while article 1457 C.C.Q. establishes the general regime of civil liability underlying Vachon inc.'s fault. Article 2098 et seq. C.C.Q., addressing the obligations of contractors and subcontractors, supported the finding that Vachon inc. failed to perform its plumbing work to accepted standards. Procedurally, article 536 of the Code of Civil Procedure sets the monetary ceiling for Small Claims Division matters, and article 328 C.C.P. permitted the court to apportion, as between co-debtors, each party's share of an in solidum condemnation where the evidence allowed it to do so.

Reasoning and analysis

The court found that Terrasses inc. — not a party to the proceeding, having been dissolved in 2014 — was in fact the general contractor, based on two contemporaneous 2004 agreements Ogesco produced, which the court found more persuasive than the documents filed by the Syndicate. Because Terrasses inc. was not before the court, any contractual fault by Ogesco toward Terrasses inc. was academic, and Maisonneuve inc. could not be treated as general contractor either. Turning to the subcontractors, the court accepted Everest's position that connecting the drainage pipe to the washer drain was a plumbing task falling to Vachon inc., which failed to perform it to the standards required of a specialized subcontractor. Vachon inc. could not excuse this by claiming it was never warned of its own oversight. The court held the Syndicate, as subrogee, was entitled to recover under the general civil liability regime given Vachon inc.'s clear fault, direct injury, and causal link. Separately, the court found the elements of the legal warranty of quality satisfied against Maisonneuve inc.: the defect was hidden behind closed walls, undetectable by a prudent buyer, present at the time of sale, and serious enough to cause significant damage. The court emphasized that successive owners were each entitled to assume the pre-installed piping had been properly connected. Because Maisonneuve inc.'s liability rested on the legal warranty while Vachon inc.'s rested on civil liability — two distinct legal sources — the court held them liable in solidum rather than solidarily, meaning the Syndicate could recover the full amount from either. Invoking article 328 C.C.P. and citing commentary on the in solidum regime, the court proceeded to apportion the parties' respective shares as between themselves, relying on the evidence that the improper installation was attributable to Vachon inc.'s original plumbing work.

Ruling and overall outcome

The court granted the Syndicate's claim and ordered Société immobilière Maisonneuve inc. and Plomberie J. Vachon inc., in solidum, to pay $15,000 to the Syndicat des copropriétaires Les Terrasses Maisonneuve, with interest at the legal rate plus the additional indemnity provided for in article 1619 C.C.Q., running from October 7, 2022. As between Maisonneuve inc. and Vachon inc. only, the court determined that Vachon inc. bore 100% of the responsibility and Maisonneuve inc. bore 0%, allowing Maisonneuve inc. to avoid a separate recursory action. Costs were awarded in favour of the Syndicate.
