The RCN began planning the in the late 1940s and originally intended to procure 14 vessels. Delays in design and construction saw the number of vessels for the
St. Laurent-class halved to 7. The 7 remaining vessels were redesigned as the Restigouche-class, taking into account design improvements found during construction of the St. Laurents.

There were seven ships of the class commissioned

Improved Restigouche (IRE)

During the late 1960s, four ships of this class were refitted to what is known as the Improved Restigouche (IRE).

This refit involved replacing the aft 3"/50 gun with an octuple ASROC

ASROC is an all-weather, all sea-conditions anti-submarine missile system. Developed by the United States Navy in the 1950s, it was deployed in the 1960s, updated in the 1990s, and eventually installed on over 200 USN surface ships, specifically cruisers, destroyers, and frigates...

The three vessels that did not receive this refit were paid off into Category "C" Reserve soon afterward, during the manpower shortages of the early-to-mid 1970s when the newly-unified Canadian Forces

Destroyer Life Extension Project (DELEX)

The four IRE vessels of the Restigouche-class that remained in active service with the CF were selected for the Destroyer Life Extension Project (DELEX) in the late 1970s. DELEX was commissioned to upgrade the ten newest St. Laurent and Restigouche-class ships with new electronics, machinery, and hull upgrades and repairs. The intent of DELEX was to extend the life of these ships for another 15 years of service while the Halifax-class frigates

.

DELEX included the installation of a Naval Tactical Data System (NTDS) known as the Automatic Data Link Plotting System (ADLIPS), as well as the Canadian Electronic Warfare System (CANEWS), and a new communication suite.

DELEX was very successful as it allowed older ships to participate in a modern electronic battle field using tactical data links between ships and aircraft.

The Kootenay suffered two mishaps during her career: In 1969 one of her gearboxes exploded, killing 7 crewmembers in one of the worst peacetime accidents in Canadian naval history. 20 years later, she collided with a freighter in 1989 and suffered bow damage and was repaired with parts removed from .

 and involved the installation of new weapons and subsequent electronics and sensors.

Among the new equipment for Terra Nova was an upgraded 3 inches (76.2 mm) rapid fire gun, Harpoon anti-ship missile launcher (8 missiles), Vulcan Phalanx 20 mm Close-In Weapon System

 (CIWS), and modified torpedo tubes for the Mk.46 Mod 50 homing torpedo. The upgrade saw the removal of the ASROC system and the well for the Limbo ASW mortar, which were replaced by Harpoon and CIWS respectively. Two 40 mm Boffin anti-aircraft guns (with an improvised fire control system) in addition to Javelin point-defense Surface-to-Air missiles and .50 cal machine guns were also added for improved close-quarter fighting.

As such, Terra Nova became the first ever guided-missile destroyer ever to serve in the Canadian Navy. Recently released documents indicate that the rapid Gulf War modification plans were determined to date back to the early 1980s as part of an emergency re-armament plan devised in case of a conventional war with the Soviet Union and/or the Warsaw Pact.
