The Protecteur-class auxiliary oiler replenishment (AOR) ships were used by the Royal Canadian Navy to resupply ships at sea with food, munitions, fuel and spare parts. They had more sophisticated medical and dental facilities than smaller warships. At 172 metres (564 ft) the ships were the largest operated by the RCN.
The Protecteur-class replenishment oilers were 171.9 m (564 ft 0 in) long, 23.2 m (76 ft 1 in) wide, and displaced up to a maximum of 24,700 tonnes (24,310 long tons) when fully loaded. Powered by two Babcock & Wilcox boilers, feeding a single General Electric steam turbine engine, the ships reached a maximum speed of 20 knots (37 km/h; 23 mph). At 20 knots, the range of the Protecteur class was limited to 4,100 nautical miles (7,600 kilometres; 4,700 miles), but could be extended to 7,500 nmi (13,900 km; 8,600 mi) when only traveling at 11.5 knots (21.3 km/h; 13.2 mph). The Protecteur class could safely navigate in as little as 10.1 m (33 ft 2 in) of water.
Three hundred and sixty five men and women served in Protecteur-class oilers, including 27 officers, and 45 air detachment personnel who operated and supported three embarked CH-124 Sea King helicopters. The crew was also responsible for loading and unloading the cargo of the Protecteur class, which included up to 14,590 t (14,360 long tons) of fuel, 400 t (394 long tons) of aviation fuel, 1,048 t (1,031 long tons) of dry cargo, and 1,250 t (1,230 long tons) of ammunition.
Two 20 mm Phalanx close-in weapon system points and six .50 calibre machine guns helped protect the cargo and crew of the Protecteur class if their BAE Systems Mark 36 SRBOC chaff launchers or AN/SLQ-25 Nixie towed decoy did not prevent enemy weaponry from endangering the ship.

Retirement and future
On 19 September 2014, Vice-Admiral Mark Norman of the Royal Canadian Navy announced the retirement of both Protecteur and Preserver, along with the Iroquois-class destroyers HMCS Iroquois and HMCS Algonquin. General wear and tear notwithstanding, Protecteur was involved in a very serious engine room fire in February 2014 and more recently corrosion problems were found on Preserver. On 27 November 2015, Protecteur and Algonquin were sold to R.J. MacIsaac Ltd. of Antigonish, Nova Scotia for scrapping. They will be towed to Liverpool, Nova Scotia where the work will be done.
Plans for replacing the class were first introduced in 2004. Lack of spare parts for the boilers and the fact that the Protecteur class are monohull tankers were the main driving points to replacing the class. The ships were intended to continue to operate until 2017, however, the Joint Support Ship Project will not be completed until two years later, leaving a gap in the ability for the RCN to refuel and resupply her own ships while deployed.
The Royal Canadian Navy looked at other options to fill the gap until the arrival of the two Queenston-class auxiliary vessels in 2019 at the earliest, The navy is currently leasing replenishment vessels from other navies, and is in the process of converting a civilian container ship to a replenishment vessel.
