In 1647,
Robert Giffard de Moncel was granted the Saint-Gabriel seignory that became property of the Jesuits in 1667 and Crown property in 1800. Around 1816,
John Neilson (1776-1848), together with
Andrew Stuart and Louis Moquin, Quebec lawyers, obtained some 50 concessions in the Saint-Gabriel seignory. This marked the start of the Val-Cartier settlement that was intended to receive Irish and Scottish colonizers. In 1832, the Parish of Saint-Gabriel-de-Valcartier was formed when it was detached from Sainte-Catherine(-de-la-Jacques-Cartier) and Charlesbourg. In 1845, the Municipality of Valcartier was created in 1845 but abolished in 1847. The Parish Municipality of Saint-Gabriel-de-Valcartier was officially established in 1855, then divided in 1862 into two municipalities: Saint-Gabriel-Ouest and Saint-Gabriel-de-Valcartier. In 1985, Saint-Gabriel-Ouest and Saint-Gabriel-de-Valcartier were merged again to form the current municipality. ==Demography==
