This year's World Cup of Hockey, which represents the event's return after a hiatus, is set for September and will be held in Toronto. The format is slightly modified from the past World Cup tournaments, with six national teams and two special "all-star teams" participating.
The eight teams that will compete this year are the United States, Canada, Sweden, Finland, Russia and the Czech Republic, plus Team Europe and Under-23 Team North America.
