In Hemlow Estate v. Co-operators General Insurance Co, 2021 ONCA 908, the Ontario Court of Appeal held that the insurer had a duty to defend a claim relating to the negligence of the insured, which resulted in the insured’s own death and property damage at the location where he was working. The court affirmed that the Pollution Exclusion did not apply, as the claim was based in negligence and breach of contract, and not from the escape of a pollutant.
