The other arm of the sea is the Honguedo Strait located on the south side of Anticosti Island and the Gaspé Peninsula.
The Jacques Cartier Strait is approximately 40 kilometres (25 mi) wide.
Jacques Cartier Strait was officially named for the French explorer Jacques Cartier in 1934 by the Geographic Board of Quebec to commemorate the 400th anniversary of his arrival in North America.[5] Prior to this, it was also known as Détroit Saint-Pierre (by Cartier himself on August 1, 1534, the day of St. Peter), Labrador Channel (until 1815), and Mingan Passage.[3]
