In 1997, Schmirler and her rink returned to the Tournament of Hearts, where they finished with a 9–2 win-loss record in the round robin. They advanced to the playoffs, and defeated Alison Goring of Ontario twice en route to winning her third Canadian championship. They then went to the World Championships, where they again finished first in the round robin and advanced to the playoffs, defeating Helena Blach Lavrsen of Denmark in the semifinals and Andrea Schöpp of Germany in the final to win a third world title. After each of these three seasons, her rink was named "Team of the Year" by Sask Sport.
