Because of their proximity and similar sporting cultures, Canada and United States are frequent rivals in a wide variety of international sports.
Overall rivalry and the Olympic Games
For both countries, the Soviet Union was often the common rival in most international competitions before 1991. However, since the fall of the Soviet Union, the two neighbouring countries have been more heated rivals, especially in winter sports where the talent pools of the two countries are more evenly matched. Although the United States has more medals than Canada in gold, silver, bronze, and total medals won throughout the history of the Winter Games, the gap has narrowed considerably over time. The rivalry is much more keenly felt by, and is often a source of angst for, Canadians, as a result of Canadian national teams being frequently humiliated by their American counterparts in most sports.
In summer sports, the Canada-USA rivalry is more muted as the United States dominates. The United States' closest rival at the Summer Olympics is now China. All time, the United States is the number one ranked country in gold, silver, bronze, and total medals won.
In the run-up to the 1998 Winter Olympics, Los Angeles Times columnist Mike Penner named Canada the United States' most important rival, especially in hockey. and USA Today ran the headline "Cold War now means Canada", with Canadian columnist Terry Jones reporting that the Canadian Olympic team approved of the comments and shared the news clippings around the athlete's village in Nagano.
In the Winter Olympics, both the United States and Canada have won the medal table once, while the US is ranked second in the all time Winter Olympic table, with Canada ranked fifth. In the Summer Olympics, the United States has won the medal count 18 times, compared to zero for Canada. The United States is ranked number 1 in the all time Summer Olympic medal table, while Canada is ranked number 20.
Based on results in Olympics, World Championships, and other major competitions for respective sports, the United States is more successful than Canada in American football, baseball, basketball, soccer, tennis, golf, swimming, athletics, boxing, lacrosse, shooting, diving, wrestling, rowing, gymnastics, sailing, cycling, weightlifting, water polo, archery, equestrian, volleyball, beach volleyball, fencing, triathlon, judo, taekwondo, figure skating, snowboarding, speed skating, alpine skiing, and bobsleigh among others, while Canada is better all time in ice hockey, curling and rugby. The United States is the most successful nation in the world in sports.
Baseball
It was considered a major upset when Canada defeated the United States in the 2006 World Baseball Classic, which some commentators called a "Miracle on Dirt", reference to the Miracle on Ice when the US national hockey team beat the USSR in 1980.
The United States beat Canada in the 2009 World Baseball Classic in Toronto. The United States also beat Canada in the 2013 World Baseball Classic. The United States beat Canada again in the 2017 World Baseball Classic, by a score of 8–0. The United States once again beat Canada in the 2023 World Baseball Classic, this time by a score of 12–1, in a game that was ended after 7 innings due to the 10 run mercy rule. Although there are only two Canadians in the U.S. Hall of Fame (Ferguson Jenkins and Larry Walker), three different Canadian players have been named MVP of either the National or American League since 1997 (Larry Walker, NL, 1997; Justin Morneau, AL, 2006; Joey Votto, NL, 2010). The United States is ranked second in the WBSC World Rankings while Canada placed 8th.
Cricket
While cricket is not among the most popular sports in either country, they have the distinction of having played against each other in the first ever international match of any sport in 1844.
Ice hockey
For both genders and at all ages groups, Canada - US games are among the most important in international hockey. Since the decline of the Soviet Union in 1991, this rivalry has certainly been one of the most passionate of all.
