HMCS Chicoutimi is a Victoria-class long-range hunter-killer (SSK) submarine of the Canadian Navy, originally built and operated by the Royal Navy as HMS Upholder. Shortly after being handed over from the UK 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. Despite all the media speculation, this was later proven to be as a result of an error in operational procedure.
