No Guarantees: Supreme Court Defines Policy Limits Of "Guaranteed" Rebuilding Coverage

In Emond v. Trillium Mutual Insurance Co.,¹ the Supreme Court of Canada addressed a consequential question for property insurers and homeowners: how far does a "Guaranteed Rebuilding Cost" ("GRC") endorsement in a standard form insurance contract extend when facing the various costs of rebuilding one's home?

In a 7-1-1 decision, the Court offers important guidance on how to interpret standard form insurance contracts, including: (i) how endorsements interact with standard form policies, (ii) how ambiguity in the insurance policy is identified and resolved, and (iii) when the reasonable expectations of the parties may shape the interpretive exercise. The majority's reasons clarify the operation of the Ledcor²framework, underscore the continuing significance of Progressive Homes³ and Sabean,⁴ and reaffirm the high threshold required to invoke the nullification of coverage doctrine.
