HMCS William Hall will be the fourth Harry DeWolf-class offshore patrol vessel for the Royal Canadian Navy. The class was derived from the Arctic Offshore Patrol Ship project as part of the National Shipbuilding Procurement Strategy and is primarily designed for the patrol and support of Canada's Arctic regions.

The lead ship of the class was announced as Harry DeWolf in September 2014, and four additional ships were named in January 2015. Construction of the ships Harry DeWolf and Margaret Brooke started in September 2015 and September 2016 at Halifax Shipyards, respectively.

Harry DeWolf and Margaret Brooke were originally planned to be delivered in 2019 and 2020 respectively. Harry DeWolf was officially launched on 15 September 2018. Margaret Brooke was launched on 10 November 2019.

The OPV is 103.6 m (339 ft 11 in) long overall with a beam of 19.0 m (62 ft 4 in). The ship will have a displacement of 6,615 metric tons (6,511 long tons). She has an enclosed foredeck that protects machinery and work spaces from Arctic climates.

The ship will be capable of 17 knots (31 km/h; 20 mph) in open water and 3 knots (5.6 km/h; 3.5 mph) while icebreaking in new year ice of 1-metre (3 ft 3 in) thickness.

She will also be equipped with a bow thruster to aid during maneuvers and docking procedures without requiring tugboat assistance. The ship will have a range of 6,800 nautical miles (12,600 km; 7,800 mi) and an endurance of 120 days with 65 personnel. William Hall will be equipped with fin stabilizers to decrease roll in open water but can be retracted during icebreaking.

The ship will be armed with one BAE Mk 38 25 mm (0.98 in) gun and two M2 Browning machine guns. The patrol ship has an onboard hangar and flight deck for helicopters up to the size of a Sikorsky CH-148 Cyclone. William Hall will have a complement of 65 and accommodation for 85 or 87.
