The insured sought a declaration that the insurer was required to pay increased rebuilding costs following a total-loss residential fire where reconstruction required upgrades mandated by the Ontario Building Code.
The insurer relied on a policy exclusion denying coverage for increased costs caused by the operation of any by-law regulating construction.
The court held that the exclusion clause applied only to municipal by-laws and not to provincial regulations such as the Building Code.
Because the increased costs arose from Building Code requirements rather than a by-law, the exclusion did not apply.
The court ordered the insurer to pay the additional costs associated with the mandated upgrades.
