CCGS Louis St Laurent



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

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.

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.

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.

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.

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.

In 2014, with CCGS Terry Fox, Louis S. St-Laurent performed a cruise to the Arctic to map the undersea continental shelf. The two vessels were slowed by thick ice conditions.

At 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 Harvey into Connoire Bay where Royal Canadian Navy divers could inspect the ship.

In 2016 Louis S. St-Laurent was deployed to the Arctic carrying an international team of scientists mapping the sea floor. The first leg of the mission was a voyage to Norway mapping the Atlantic. This was to be followed by a 47-day leg to the North Pole. Travelling with the Swedish icebreaker Oden, Louis S. St-Laurent’s mission to the Arctic was the last of three performed in order to define Canada’s claim to the Arctic continental shelf. While mapping during transit to the north, the scientists aboard the ship discovered a chain of 25–30 undersea volcanoes off the coast of Greenland.
