What major international tournament features Canada and other teams every four years?

The major international tournament that features Canada and other teams every four years is the Olympic Games. Although the IIHF World Championship and the World Cup of Hockey are significant events in international hockey, they do not follow a four-year cycle like the Olympics do.

The Winter Olympic Games include ice hockey as one of the key sports, and they take place every four years, showcasing teams from countries around the world, including Canada, which has a strong hockey tradition. This event garners great attention and is one of the most prestigious platforms for hockey players to compete at the highest level, allowing countries to represent themselves on an international stage.

The NHL All-Star Game, meanwhile, is an exhibition game held annually during the NHL season and does not involve a broader international representation of countries. Therefore, the Olympic Games is the correct answer for identifying the tournament that features Canada and other teams on a four-year cycle.
