The Rivalry Series was introduced by USA Hockey and Hockey Canada last season and comprised three games between the women’s national teams of the two countries. Two games of the 2019-20 Rivalry Series will take place in December and three in February. The U.S. and Canada have battled in the gold-medal game of every IIHF Women’s World Championship and Olympic Winter Games staged, with just two exceptions (2018 World Championship, 2006 Olympics).
