They are Sandra Schmirler of Biggar, Saskatchewan, who won the gold medal in women's curling at the 1998 Olympic Winter Games in Nagano, Barbara Ann Scott of Ottawa, Ontario, who won a gold medal in women's figure skating at the 1948 Olympic Winter Games in St. Moritz, and freestyle skier Sarah Burke of Barrie, Ontario.
Burke, a four-time Winter X Games champion in women's superpipe skiing, was instrumental in persuading the International Olympic Committee to grant halfpipe skiing and slopestyle skiing full Olympic status at the 2014 Olympic Winter Games in Sochi.
Tragically Burke died in a training accident in Utah in 2010. Schmirler died of cancer in 2000, while Scott died at the age of 84 in 2012.
The Canadian Post made the decision to design the stamps two days before competition will start at the 2014 Olympic Winter Games in Sochi.
