The Barony de Longueuil of Longueüil in the Province of Quebec, Canada, was granted on 26 January 1700 by Louis XIV of France, to Charles le Moyne de Longueüil, with remainder to the heirs males or female of his body.
After the conquest of Quebec by Britain in 1759, the Treaty of Paris, dated 10 February 1763, allowed for ‘all rights and privileges of what kind soever were reserved to all of French descent who were entitled thereto under the former government’.
King Louis gave a grant of land in the north-east corner of Montreal to Charles le Moyne in 1657, which was named Longueil, after his mother’s hometown in France; Longueil in Normandy. By 1710, this land spanned from the St Lawrence River to the Richelieu River and at its largest consisted of about 150 square miles. Much of it was sold in 1854. The arms of the city of Longueil in Quebec are based on the arms granted to the first baron and were presented to the city in 2004 in the presence of the 11th baron
This title is unique in that it is the only Canadian hereditary title still surviving today, but as it is not a UK peerage it has no precedence amongst other peers of equal rank.
