CCGS Louis S. St-Laurent is a Canadian Coast Guard Heavy Arctic Icebreaker. Louis S. St-Laurent's home port is St. John's, Newfoundland and Labrador[5] and is stationed there with other vessels of the coast guard.

Named after the twelfth Prime Minister of Canada, The Right Honourable Louis St. Laurent, PC CC QC LLD DCL LLL BA. The vessel is classed a "Heavy Arctic Icebreaker" and is the largest icebreaker and flagship of the CCG.

Operations

Louis S. St-Laurent is based at CCG Base St. John's in St. John's, Newfoundland. The vessel's current operation tempo consists of summer voyages to Canada's Arctic where she supports the annual Arctic sealift to various coastal communities and carries out multi-disciplinary scientific expeditions. During the winter months, Louis S. St-Laurent sometimes operates in the Gulf of St. Lawrence to aid ships in transiting to Montreal, Quebec, although she usually only serves this assignment during particularly heavy ice years.

Louis S. St. Laurent was launched 3 December 1966 by Canadian Vickers Limited at Montreal, Quebec and commissioned in October 1969.[6]

From 8-22 September 1969 Louis S. St-Laurent sailed on the SS Manhattan expedition in the Northwest Passage. She was assisted by CCGS John A. Macdonald and the United States Coast Guard vessels USCGC Northwind and USCGC Staten Island [7]

During 1976 Louis S. St-Laurent, Captain Paul M. Fournier in command, made a partial transit of the Northwest Passage traveling from east to west, through Lancaster Sound, Peel Sound, and Victoria Strait.[8]

In 1979 Louis S. St-Laurent, Captain George Burdock in command, made a full east to west transit of the Northwest Passage. She assisted CCGS Franklin, and circumnavigated North America.[9]

Louis S. St-Laurent underwent an extensive and costly modernization at Halifax Shipyard Ltd. in Halifax, Nova Scotia between 1988-1993 which saw her hull lengthened as well as new propulsion and navigation equipment installed.

The modernization program was controversial as the government of Prime Minister Brian Mulroney had initially proposed building a class of mega icebreakers (the Polar 8 Project) for promoting Canadian sovereignty in territorial waters claimed by Canada; USCGC Polar Sea had made an unauthorized transit of Canada's Northwest Passage in 1985 early in Mulroney's administration, provoking a strong nationalist out-cry across the country. However, budget cuts in the late 1980s saw proposed expansions of the coast guard and armed forces scrapped. In compensation to the coast guard, the government opted to modernize the largest icebreaker in its fleet, Louis S. St-Laurent.

On 22 August 1994 Louis S. St-Laurent and USCGC Polar Sea became the first North American surface vessels to reach the North Pole.

In the summer of 2006, CBC TV's The National broadcast from Louis S. St-Laurent in a special series focused on climate change.[10]

The vessel was originally scheduled to be decommissioned in 2000 however a refit extended the decommissioning date to 2017. In the 26 February 2008 federal budget, the Government of Canada announced it was funding a $721 million "Polar Class Icebreaker" (named John G. Diefenbaker) as a replacement vessel for Louis S. St-Laurent.[11][12][13][14][15]

On 1:30 a.m. on 2 April 2015, Louis S. St-Laurent, arrived near Burgeo, Newfoundland and Labrador to take the damaged Canadian Coast Guard vessel CCGS Ann Harvey under tow. Ann Harvey, which had run aground near Burgeo, was already being towed by the lifeboat CCGS W.G. George when the icebreaker arrived. Louis S. St-Laurent took over the tow and brought Ann Harvery into Connoire Bay where Royal Canadian Navy divers could inspect the ship.[16]
