21 nations participated in three different divisions or pools: For the eighth straight year, the Soviet Union won the world championship.

[1] However, after a dispute over allowing professional players in international tournaments, the IIHF awarded the championships to other cities.

[1] Canada was scheduled to be the original host nation of Group A for the 1970 Ice Hockey World Championships, and the International Ice Hockey Federation (IIHF) had granted use of up to nine former professional players for national teams at the event.

[3][4] Canadian officials were frustrated that their best players, competing in the National Hockey League (NHL), were prevented from playing while Soviet players, who were "employees" of the industrial or military organizations that fielded "amateur" teams, were allowed to compete.

[4] CAHA president Earl Dawson argued that national teams participating in Izvestia Trophy tournaments had played against professionals, but were still eligible for the Olympics and the same should apply to the World Championships.

[6] He also made the suggestion to consider the 1970 event an invitational tournament instead of a World Championships to avoid the wrath of the IOC, but the IIHF declined the notion.

[7] Canada perceived the situation to be a double standard in international hockey since players on European national teams were believed to be state-sponsored professionals labeled as amateurs.

[7] Dawson felt that Sweden and the Soviet Union combined to sabotage the Canadian attempt to host the 1970 World Championships, because Sweden wanted to host the event and the Soviets did not want to lose the gold medal.
