HMCS Columbia was a Restigouche-class destroyer that served in the Royal Canadian Navy and later the Canadian Forces from 1959 to 1974. Columbia was the seventh and final ship in her class and is the second Canadian naval unit to carry the name HMCS Columbia. Following her service, she was kept at Esquimalt in an altered condition, no longer capable of sailing. During the summer of 1974 she along with her sister ship HMCS Chaudiere served as the base of operations for the Esquimalt Sea Cadet Camp while being docked at the DND jetty in Colwood. This location was across the harbour from the main site of CFB Esquimalt. Columbia was sold for use as an artificial reef and sunk off the coast of British Columbia in 1996.
