CCGS John A. Macdonald

CCGS "John A. Macdonald" was a Canadian Coast Guard heavy icebreaker. She was named after The Right Honourable, Sir John Alexander Macdonald, the first Prime Minister of Canada. The ship was commissioned into the Canadian Department of Transport's Marine Service in 1960 using the prefix "Canadian Government Ship" (CGS). The vessel was transferred in 1962 into the newly created Canadian Coast Guard (CCG) and served with distinction until being decommissioned in 1991, and replaced by the then-chartered (but later purchased) .
Design and description.
Considered one of the finest icebreakers ever constructed for the Canadian service, "John A. Macdonald" was long overall with a beam of and a draught of . The vessel had a fully loaded displacement of and had a gross register tonnage (GRT) of 6,186 tons.
The ship was propelled by three screws driven by a diesel-electric system creating . This gave the vessel a maximum speed of . The vessel could carry two helicopters.
Service history.
The vessel was constructed by Davie Shipbuilding at their yard in Lauzon, Quebec with the yard number 620 and launched on 31 October 1959. During construction, the vessel was visited by Soviet officials who took interest in her design. There was a distinct resemblance to "John A. MacDonald" in the five ships in the next class of Soviet icebreaker, though they were larger and more powerful. The vessel entered service as part of the government fleet in September 1960 as CGS "John A. Macdonald".
In 1962, "John A. Macdonald" transferred to the newly created Canadian Coast Guard and set a record by reaching Tanquary Fjord, the closest to the North Pole a Canadian vessel had ever been. In 1967, "John A. Macdonald" transited the Northwest Passage in order to aid the smaller icebreaker in the western Arctic. Following that, the icebreaker then travelled to assist after the United States Coast Guard vessel became trapped in heavy ice north of Point Barrow, Alaska. The vessel then returned to the East Coast via the Panama Canal, circumnavigating North America in the process. "John A Macdonald" was awarded the U.S. Coast Guard Unit Commendation "for extremely meritorious service in the support of United States Coast Guard operations during the period of 23 September 1967 to 08 October 1967", during the Arctic West Summer 1967 cruise by Admiral Willard J. Smith, Commandant, United States Coast Guard.
In 1969 "John A. Macdonald" assisted the then-new in rescuing during her transit of the Northwest Passage. "John A. Macdonald" made a double transit from the east to west and returned west to east. During the rescue, "John A. Macdonald" broke her starboard propeller in heavy ice; the propeller is on display by the Dartmouth Ferry Terminal, Dartmouth, Nova Scotia. "John A. Macdonald" was assisted by the United States Coast Guard icebreakers "Northwind" and 
In 1974 the merchant vessel "Atlantean I" was damaged on Lake Ontario, received repairs at Montreal and Quebec City and failed to pay for them. An order of arrest was produced but the vessel sailed without authorization. In February 1975, the Gulf of St. Lawrence was filled with ice and "John A. MacDonald" was sent to intercept the ship, now renamed "Answer". Stuck in ice and boarded by lawyers bearing the warrants, the captain of the merchant vessel refused to sail for Gaspé, Quebec. On 28 February, Royal Canadian Mounted Police and Canadian Coast Guard personnel were placed on board the merchant and the two ships sailed for Sept-Îles, Quebec. However, as soon as "Answer" was free of the heavy ice, the ship broke escort and fled for the Atlantic. After legal arguments were heard over the right of Canada to seize the vessel, the ship was boarded a third time, the crew taken off and "Answer" and "John A. Macdonald" arrived at Sept-Îles on 7 March.
Also in 1975, "John A. Macdonald" made a partial transit of the Northwest Passage, westward, through Lancaster Sound, Peel Sound and Victoria Strait, and sailed to aid CCGS "Camsell" again after the smaller Coast Guard ship was damaged in the Western Arctic. In 1977, the ship was chartered to Dome Petroleum. During 1978 "John A. Macdonald" made an east to west partial transit of the Northwest Passage, traveling on charter to Dome Petroleum, through Lancaster Sound, Prince of Wales Strait and the Beaufort Sea. During the winter of 1978–79, the vessel was laid up. In 1979, the vessel made another partial transit of the Northwest Passage, west to east, returning eastward from a charter operation. "John A. Macdonald" returned to Coast Guard service in 1980 and supported the search that confirmed the wreck of , which had been crushed by ice and sank in the Arctic Ocean in 1853. The following year, "John A. Macdonald" escorted a factory barge to Little Cornwallis Island where the barge was beached and incorporated into the island.
During 1985 "John A. Macdonald" made a further partial transit of the Northwest Passage traveling westward, through Peel Sound, Victoria Strait, Amundsen Gulf and back. That year, the icebreaker was sent to escort through Canadian waters as far as Viscount Melville Sound during the American vessel's unauthorized transit through waters claimed by Canada. In 1987 she underwent an eight-month, $8-million (CAD) refit. In 1988 the ship made another partial transit of the Northwest Passage traveling westward, through Lancaster Sound, Peel Sound and Demarcation Point then back. In November–December 1989, the Canadian Coast Guard went on strike and "John A. Macdonald" was the only Coast Guard vessel to remain at sea, escorting to Nanisivik.
The ship was taken out of service in 1991. The vessel was replaced by , initially on charter to the Canadian Coast Guard, which was later purchased. The vessel was transferred to Crown Assets and was renamed "1201". The ship was then sold for scrap in 1993 and broken up in 1995.
