Gill v. Wawanesa Mutual Insurance Co., [2022] B.C.J. No. 1048, 2022 BCSC 981, British Columbia Supreme Court, June 10, 2022, C.J. Giaschi J.

The insured sought coverage from his insurer pursuant to the sewer back-up endorsement for water damage resulting from water back-up due to a clogged perimeter drainage system.  The water escaped through a drain located in the sun deck and entered the home’s basement from the deck.  The sewer back-up endorsement provided coverage for a “sudden and accidental backing up or escape of water or sewage within your dwelling … through a sewer on your premises.”  The insurer denied coverage on the basis that the sudden and accidental backing up or escape of water did not occur “within the dwelling”.  The Court held that although the sun deck was part of the dwelling, it was not inside the exterior walls of the building and therefore was not “within the dwelling”.  The escape of water did not occur “within the dwelling”.
