Virtue and Moir, who will retire after Pyeongchang, were undefeated in their return until losing to Papadakis and Cizeron in the Grand Prix Final in December.
A large contingent of Canadian athletes, including moguls gold medallist Mikael Kingsbury, were at Gangneung Ice Arena to cheer on Virtue and Moir.
