1970 IIHF World Championship (WFAC)

The 1970 IIHF Ice Hockey World Championships was the 37th edition of the Ice Hockey World Championships hosted by the International Ice Hockey Federation (IIHF). Teams participated at three levels of competition. Pool A was played between 2–15 September 1970 in in Montreal and Winnipeg, Canada. Pool B was arranged in Oslo, Norway between 24 February - 5 March 1970, while Pool C was arranged in in Galaţi, Romania between 13–22 February 1970.

The tournament was the first true best-on-best world championship in hockey history as it allowed any player to represent their team regardless of amateur or professional status. Despite this, the Soviet Union won the world championship for the eighth straight year after defeating the Soviet Union in the final in two consecutive games. Originally the tournament was scheduled to be held in Montreal and Winnipeg in Canada. However, after a dispute over allowing professional players in international tournaments, the Canadian team withdrew from hosting and competing in international hockey. Consequently, the success of the event paved the way for greater use of professional players in the World Championship and later the Winter Olympics. This tournament was also the first one to make helmets mandatory for all skaters.
