St-Louis, an Olympic silver medallist and five-time world champion in women's hockey, will share the role and responsibilities with decorated freestyle skier Jean-Luc Brassard, who called her "a wonderful addition to our team."
Downhill skiing legend Steve Podborski was named Canada's chef de mission in February 2012.
“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, adding that "it is going to be an honour to work alongside two incredible individuals like Steve and Jean-Luc.
"I am tremendously motivated and humbled to contribute to the Canadian Olympic Team at Sochi 2014 Olympic Winter Games. 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 is a recipient of the Canadian Association for the Advancement of Women in Sport and Physical Activity (CAAWS) Breakthrough Award in recognition of her immense contribution to women in sport and particularly to women’s hockey.
But she is best known for having served as captain of Canada's national women's hockey team from 1992-94, winning silver at the 1998 Nagano Games.
"Today, we add the knowledge and capacity of one of this country's greatest ice hockey athletes to our Sochi 2014 Team," Podborski said of St-Louis. "We have just taken one step closer to our quest in becoming the No. 1 country in total medals at next year's Winter Olympic Games.
"Our athletes and coaches have just gained access to an incredible amount of depth and perspective from an athlete who knows what it takes to win."
'An exceptional amount of experience'
"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," noted Marcel Aubut, president of the Canadian Olympic Committee. "In addition to the tremendous talents that Steve and Jean-Luc bring to the leadership team, France will provide an exceptional amount of experience to our Olympic athletes as they compete against the world's best."
St-Louis is currently teaching physical education at Cegep du Vieux-Montreal, a post-secondary institution dedicated to supporting excellence in sports and physical wellness among Canada's youth.Suggest a correction
