Zardev Inc. v. Joseph J. Dydzak, et al. (41291)

The respondents are owners of lots that border three lakes in Ville d’Estérel. Following the renewal of the cadastre of Ville d’Estérel in 2016, the respondents discovered that they were not owners of a submerged strip of land that goes around each of the lakes and is situated in front of their respective lots. The appellant claimed to own that strip of land, immatriculated separately in the cadastre as several lots, whereas the respondents stated that they own it. Through an application for a declaratory judgment, the respondents sought a declaration confirming that they are respectively owners of the submerged lots adjacent to the lands they own. The Quebec Superior Court dismissed their application, finding that the submerged lots are the property of the appellant. The Quebec Court of Appeal allowed the respondents’ appeal in part. It found that the submerged strip of land is accessory to the riparian lots pursuant to the doctrine of accessory. Argued Date 2025-11-10 Keywords Property — Immovables — Submerged lots — Extent of right of ownership near watercourses and lakes — Doctrine of accessory — Whether doctrine of accessory is applicable to lots submerged as result of construction of dam — If so, whether doctrine should apply only in residual manner, if doubt persists as to common intention of parties — Whether Court of Appeal erred in interfering, without identifying palpable and overriding error, with findings at trial concerning interpretion of words [TRANSLATION] “bounded by the lake” and common intention of parties.
