These ships also had reduced armament and speed compared to their predecessors. They were not seen as effective anti-submarine warfare vessels by the United States Navy and were sold after only 15 years service to the Indonesian Navy.

The Mackenzie-class destroyer was a class of warship used by the Royal Canadian Navy and Canadian Forces from the 1960s–1990s. Six such ships were envisioned, of which four were completed to this specification. The last two hulls were completed to the post DDH conversion St. Laurent-class design ; they were designated as the Annapolis class instead. The four Mackenzie-class destroyers spent most of their service in the Pacific Ocean, used primarily in a training role. Their only significant update was the DELEX program, which was completed between 1982 and 1985 and updated their navigational radar and their sonar.

During the summer of 1974 she along with her sister ship HMCS Columbia 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. Following the vessel's decommissioning, the ship was used as a source for spare parts for the other surviving members of her class. In 1991, Chaudière was sold for use as an artificial reef and sunk off the coast of British Columbia.
