St-Louis was named an assistant chef de mission for the Games, joining chef de mission Steve Podborski and assistant chef Jean-Luc Brassard.
"What an extraordinary occasion this is for me, an opportunity to be part of the Olympic Movement — something that I have believed in for many years," St-Louis said. "It is going to be an honour to work alongside two incredible individuals like Steve and Jean-Luc. I know how important it is for our athletes to be prepared both physically and mentally in order to achieve their desired objectives and this is exactly what I aim to deliver.”
St-Louis was a member of the women's hockey team that won silver at the 1998 Nagano Olympics, and was captain of the team from 1992 to '94. She was also a competitive lacrosse player.
"If we want to become the best Olympic nation in the world, we need to gather the best-qualified Canadians to help lead our athletes and coaches," said Canadian Olympic Committee president Marcel Aubut.
St-Louis has been teaching physical education at the Cegep du Vieux-Montreal, a post-secondary school that supports excellence in sports.
