CFS Shelburne (HMCS Shelburne)
During the Second World War, a large naval repair base was established at Shelburne, Nova Scotia, where many Allied ships were refitted and repaired following their work maintaining convoy and antisubmarine surveillance in the Atlantic. During the Cold War, HMCS (later CFS) Shelburne played an important role in antisubmarine warfare, part of the SOSUS/IUSS network of passive sonar stations that identified and tracked Soviet submarines. CFS Shelburne was decommissioned in 1995.
