Langlois teamed up with Patrice Archetto in 1998. She fractured her skull as a result of a fall on a throw jump at the 1998 Canadian Championships. She wore a hockey helmet for six months afterward. Langlois/Archetto won the silver medal at the 2002 Four Continents Championships, five Grand Prix medals, and five Canadian national medals. Jan Ullmark coached the pair in Edmonton. Their partnership ended when Archetto retired from competition in 2005.
