Facts and outcome of the case

Background of the dispute
The case arose when a burst watermain caused flooding to the respondent’s property. The property owner sought coverage under their insurance policy issued by Dominion of Canada General Insurance. The policy contained an exclusion clause that denied coverage if water entered the property through basement walls. Based on this clause, the insurer refused coverage, arguing that the water entered via a pipe embedded in the basement wall.

Court’s analysis
The court examined the wording of the exclusion and whether a pipe transecting a basement wall could reasonably be considered part of the “wall” for purposes of policy interpretation. It emphasized that a wall functions to enclose and protect a property, while a pipe is a distinct structure that exists to allow the passage of fluids. Since the exclusion specifically referred to water entering “through basement walls,” the court found that it could not be stretched to include pipes. Furthermore, the court noted that insurance contracts are interpreted strictly against insurers when exclusions are ambiguous, reaffirming the principle of contra proferentem.

Decision on appeal
The appellate court upheld the motion judge’s ruling in favor of the respondent. It confirmed that the insurer had not proven the exclusion applied, as the water entered through a pipe and not through the wall itself. The exclusion clause did not expressly cover such a scenario, and ambiguity must be resolved in favor of the insured.

Outcome
The appeal was dismissed, and Dominion of Canada General Insurance was required to provide coverage for the damage. Additionally, the court awarded costs of $8,000 to the respondent.
