HMCS Chicoutimi is a Victoria-class long-range hunter-killer (SSK) submarine of the Royal Canadian Navy, originally built and operated by the Royal Navy as HMS Upholder. Shortly after being handed over by the United Kingdom to Canada she was involved in a partial flooding incident which resulted in a fire at sea. The incident sparked a fierce debate over the value of the purchase of this group of second-hand vessels, as well as the handover inspection process. The subsequent investigation "determined the fire was caused by human, technical and operational factors, [and] the board cleared the commanding officer and crew of any blame."^[1] The submarine was repaired and entered Canadian service in 2015.
