Langlais played high school football at École secondaire Mont-Bleu for Les Panthèresearch He first played college football at Cégep Beauce-Appalaches as a linebacker from 2009 to 2011 before transferring to the Université de Sherbrooke. While playing for the Sherbrooke Vert et Or, he played as a linebacker in 2012 and a defensive end in 2013, before moving to the offensive side as a running back in his final year.
During his only year as a running back at the collegiate level, Langlais rushed only four times for 14 yards, adding five catches for 44 yards.
Despite relatively unimpressive statistics in his single year as a running back at Sherbrooke, Langlais attracted the attention of scouts after performing well at the regional Canadian Football League Combine in Montreal and the national Canadian Football League combine in Toronto, including recording the fastest shuttle time of 4.08 seconds and a 40-yard time of 4.71 seconds in Montreal. He was selected by the Calgary Stampeders in the third round of the 2015 Canadian Football League Draft with the 27th overall pick, and was signed by Calgary on May 28, 2015.
He made the active roster following the preseason, and debuted in the Stampeders" first week game against the Hamilton Tiger-Cats.
