Description
Endeavour had a displacement of 1,560 long tons (1,585 t) at full load with a length overall of 236 feet 0 inches (71.9 m), a beam of 38 feet 6 inches (11.7 m) and a draught of 13 feet 0 inches (4.0 m). Endeavour's hull was stiffened for work in areas with ice.
The ship was propelled by two shafts driven by a diesel-electric engine creating 2,960 shaft horsepower (2,207 kW). The machinery space was insulated to reduce noise. This gave the vessel a maximum speed of 16 knots (30 km/h) and a range of 10,000 nautical miles (19,000 km) at 12 knots (22 km/h). Endeavour could turn 21⁄2 times its length. The ship had a 48-by-31-foot (14.6 m × 9.4 m) helicopter deck. The ship was fitted with two 9-ton Austin-Weston telescopic cranes. Two oceanographical winches, each holding 5,000 fathoms (9,100 m) of wire, two bathythermograph winches and one deep-sea coring winch were also fitted. The vessel had a complement of 50, which included 10 officers, 13 scientists and two aircrew.
CCGS Labrador was a Wind-class icebreaker. First commissioned on 8 July 1954 as Her Majesty's Canadian Ship (HMCS) Labrador in the Royal Canadian Navy (RCN), Captain O.C.S. "Long Robbie" Robertson, GM, RCN, in command. She was transferred to the Department of Transport (DOT) on 22 November 1957, and re-designated Canadian Government Ship (CGS) Labrador. She was among the DOT fleet assigned to the nascent Canadian Coast Guard (CCG) when that organization was formed in 1962, and further re-designated Canadian Coast Guard Ship (CCGS) Labrador. Her career marked the beginning of the CCG's icebreaker operations which continue to this day. She extensively charted and documented the then-poorly-known Canadian Arctic, and as HMCS Labrador was the first ship to circumnavigate North America in a single voyage. The ship was taken out of service in 1987 and broken up for scrap in 1989.
CCGS Sir Wilfred Grenfell is a Canadian Coast Guard vessel based in Victoria, British Columbia. Designated an "Offshore Ice Strengthened Multi Patrol Vessel", the former offshore supply vessel is named after the medical missionary in Labrador, Sir Wilfred Grenfell.

In 1994, she played an important role in the fishing conflict known as the Turbot War in the Atlantic Ocean.
CCGS Cygnus is a Cape Roger-class fisheries patrol vessel of the Canadian Coast Guard. The ship entered service in 1981 and is used to monitor the fisheries along the Atlantic coast of Canada. During the Turbot War, Cygnus was among the Coast Guard vessels sent to monitor the European fishing fleet on the Grand Banks.
CCGS Hudson was an offshore oceanographic and hydrographic survey vessel operated by the Canadian Coast Guard. The ship entered service in 1963 with the Canadian Oceanographic Service, stationed at the Bedford Institute of Oceanography, called CSS Hudson. The ship made several significant scientific voyages, among them the first circumnavigation of the Americas in 1970. The ship was transferred to the Canadian Coast Guard in 1996 and decommissioned in 2022. A replacement is not scheduled for delivery until 2024–2025.
CCGS Limnos is a Canadian Coast Guard coastal research and survey vessel and it is named after the Greek island of Limnos which itself derived from "limni", the Greek word for lake. The ship entered service in 1968 and is currently active. The ship is based on the Great Lakes at the Coast Guard Base in Burlington, Ontario and is used for hydrographic and limnological research.
Gauss was a ship built in Germany specially for polar exploration, named after the mathematician and physical scientist Carl Friedrich Gauss. Purchased by Canada in 1904, the vessel was renamed CGS Arctic. As Arctic, the vessel made annual trips to the Canadian Arctic until 1925. The ship's fate is disputed among the sources, but all claim that by the mid-1920s, the vessel was out of service.

The ship sank in 1925, was raised and re-entered service, remaining with the fleet through the Second World War as an examination vessel at Prince Rupert, British Columbia. After the end of the war, the vessel entered mercantile service becoming A.G. Garrish in 1947, later renamed Arctic Rover in 1958, Laforce in 1962 and Polaris in 1973. The ship's registry was deleted in 1991.

CCGS Tupper was a Canadian Coast Guard ice-strengthened buoy tender that served from 1959 to 1998. The vessel spent her entire career on the East Coast of Canada. Following her Canadian service, Tupper was sold to private interests with the intention of converting her to a yacht, but the conversion never happened and the vessel moved about Halifax Harbour, suffering a fire in 2008 before being sold for scrap in 2011. The vessel was not scrapped and the Canadian Coast Guard was forced to address the pollution concerns of the abandoned vessel in 2021.
CFAV Quest was an oceanographic research/acoustic vessel used by the Royal Canadian Navy and Defence Research and Development Canada. It was the only ship with this capability in the fleet. Based out of Halifax, Nova Scotia, Quest's crew were civilian members of the Canadian Department of National Defence and the ship was classified as an auxiliary vessel (CFAV). In 2016 it was announced the ship was to be divested and ultimately decommissioned by the end of the year.
CCGS Earl Grey is a Samuel Risley-class light icebreaker and buoy tender in the Canadian Coast Guard. Constructed in 1986, the vessel serves a variety of roles, including light ice-breaking and buoy tending, as well as being strengthened for navigation in ice to perform tasking along the shores off the Atlantic coast of Canada. Like her sister ship, CCGS Samuel Risley, she carries a large and powerful crane on her long low afterdeck for manipulating buoys. Earl Grey is the second icebreaker in Canadian service to carry the name.
CCGS Simon Fraser was a buoy tender operated by the Canadian Coast Guard. The vessel entered service in 1960 with the Department of Transport's Marine Fleet, before being transferred to the newly formed Canadian Coast Guard in 1962. The buoy tender served on both coasts of Canada and was used for search and rescue duties along the West Coast of Canada. The ship was loaned to the Royal Canadian Mounted Police in 2000 and transited the Northwest Passage, circumnavigating North America in the process. The ship was taken out of service in 2001 and sold to private interests. In 2006, the vessel reappeared as a yacht using the same name.
The Dun class of tankers comprised two ships, HMCS Dundalk and HMCS Dundurn, constructed for the Royal Canadian Navy during the Second World War. The two vessels were ordered by the Royal Canadian Navy to fill a need to transport fuel oil for convoy escorts in the Battle of the Atlantic. The two vessels began their careers in 1943 and remained in naval service until 1946. Following the end of the war, they were crewed by civilians as naval auxiliaries until the 1980s. Dundalk was wrecked in 1984 and Dundurn's ultimate fate is unknown.
HMCS Whitethroat was a controlled minelayer based on the Isles-class naval trawler constructed for Canada in the United Kingdom during World War II. The ship was completed near the end of the war and most of its naval service was spent dismantling the defences erected during the war. In 1946 the ship was paid off and became a naval auxiliary and given the new prefix CNAV Whitethroat. As an auxiliary, Whitethroat was used a naval research platform and to repair undersea cables. Reactivated for the Korean War as a minelayer again, the vessel returned to auxiliary service on the Pacific Coast from 1954 to 1967. Whitethroat was sold for scrap in 1967.
