The site was also used as an internment camp for "enemy aliens", mainly eastern Europeans. The name Valcartier comes from the town of Saint-Gabriel-de-Valcartier, of which a large section was expropriated in order to create the military training camp. Due to its proximity to the Port of Quebec, Valcartier became the largest military camp on Canadian soil, including some 32,000 men and 8,000 horses. In 1968, after unification of the Canadian Forces, the title 5 Canadian Mechanized Brigade Group was assigned to the brigade group established in CFB Valcartier.
