The Emonds’ home was destroyed by flooding and deemed a total loss. The property was situated within the jurisdiction of a conservation authority, which is empowered to regulate development activities. To rebuild, the Emonds were required to undertake additional work to comply with the conservation authority’s requirements. A dispute arose concerning whether those increased compliance costs were recoverable under the Emonds’ homeowner’s insurance policy.
The policy includes a guaranteed rebuilding cost endorsement (“GRC endorsement”) that amends the “Basis of Claim Payment” provision, which provides the basis of loss settlement in the event of damage. The GRC endorsement provides that the insurer “will pay for insured loss or damage if [the insureds] repair or replace the damaged or destroyed [house] on the same location with materials of similar quality using current building techniques …” The GRC endorsement concludes with a statement that “in all other respects, the policy provisions and limits of liability remain unchanged”.
The policy also contains an exclusion for “increased costs of repair or replacement due to operation of any law regulating the zoning, demolition, repair or construction of buildings and their related services; except as provided under Additional Coverages of Section 1” (“compliance cost exclusion”). One of the Additional Coverages exceptions states that the insurer will pay an additional amount up to $10,000 for the “increased cost” to comply with zoning and construction‑related laws.
The Emonds sought to restore the application judge’s order declaring that the GRC endorsement entitled them to recover the total costs of rebuilding their house, with no limitation for the cost of complying with the conservation requirements.
The Supreme Court dismissed the appeal, confirming that the Emonds were not entitled to recover increased compliance costs beyond $10,000.
The insureds advanced multiple ambiguity arguments. The Court, after reviewing longstanding principles of insurance contract interpretation, addressed each argument in turn and explained why, in every instance, the policy language supported only one reasonable meaning:
- The heading of the GRC endorsement (“Guaranteed Rebuilding Cost Coverage”) does not convey a promise that the insurer was guaranteeing to pay all rebuilding costs. Such an interpretation would require reading the word “guaranteed” in isolation rather than in the context of the contract as a whole. As the Court stated, “[t]he heading of an endorsement cannot overwhelm otherwise unambiguous language” (para. 82).
- The GRC endorsement does not negate the operation of the compliance cost exclusion. Because the GRC endorsement simply amends the Basis of Claim Payment provision, the exclusions in the policy continue to apply to the amended provision as they did to the original. This is further confirmed by language in the endorsement that “In all other respects, the policy provisions and limits of liability remain unchanged”.
- The phrase “current building techniques” does not extend coverage for the compliance costs. The ordinary meaning of “technique” refers to a specific way of performing a task. The phrase “current building techniques” thereby refers to modern construction methods, rather than the broader legal requirements to perform additional work. As an example, the court noted that the conservation authority required a septic system upgrade as a prerequisite for the rebuilding permit – such a requirement is not a “technique”.
- The compliance cost exclusion unambiguously captures the conservation authority’s requirements. The phrase “any law” is not limited to statutes enacted by a legislature but includes by-laws and regulations. The conservation authority’s Regulation Policiesare thereby included in the definition of “any law”.
- The compliance cost exclusion is not limited to laws enacted after the policy was issued or renewed. The language of the exclusion contains no temporal dimension; rather the words “due to” clearly link the increase in costs to the operation of “any” law regardless of when it came into force. Where increased costs are meant to be calculated by reference to the time when the contract was issued, the contract says this explicitly.
Lastly, the court rejected the Emonds’ argument that the compliance cost exclusion nullifies the benefit bargained for under the GRC endorsement. The court explains that the primary benefit of the GRC endorsement is the removal of the payout cap under the standard base policy, thereby permitting recovery of actual replacement costs even when they exceed the limit listed on the declaration page. Those insureds who have opted for the endorsement would continue to enjoy this benefit, as the recoverable cost of replacement, less compliance costs, may still exceed the amount listed on the declaration page.
The Court concluded that the contested language was clear and unambiguous. The exclusion applied to the increased costs of complying with the conservation authority’s requirements, despite the GRC endorsement. Applying the compliance cost exclusion does nothing to nullify or otherwise interfere with the purpose of the GRC endorsement. The Emonds are not, therefore, entitled to recover increased compliance costs beyond $10,000.
The decision reinforces that interpretive arguments in insurance contracts must be anchored in the policy text, read as a whole, with clear and unambiguous language given effect and ambiguity recognized only where a provision admits of more than one reasonable interpretation.
