IIHF revises world championship formatCanada will benefit from scheduling revisions for world hockey championships approved at a recent congress of the International Ice Hockey Federation in Aosta, Italy.The annual tournament is being moved further into spring, which * will allow Canada to wait until well into the NHL playoffs before filling its roster, said Gordon Renwick of Cambridge, Ont., who was reelected to a second fouf-year term as vice-president.Delegates agreed the 1992 tournament in Czechoslovakia will not begin until the last week of April, when two rounds of Stanley Cup playoffs will have been completed. The trend gained momentum last year when the start of the 1991 tournament in Helsinki was set for April 19 â one of the latest start dates ever.The 1993 world tournament was awarded to West Germany and the 1994 tournament to Italy.Ohe of the major congress decisions was to increase the number of teams in Group A from eight to 12, starting in '92. As a result, no team will be dropped from Group A in Helsinki. Instead, the top four teams in Group B will be promoted to Group A. The top four in Group C will join Group B and Group D willbe dropped, with those teams joining Group C.Because a Canada Cup tournament will be held in September 1991 and the Olympics are in Albertville, France, during the winter of 1992, the IIHF agreed that the Moscow Izvestia tournament, usually held every December, would not be held in 1991.Gunther Sabetzki of West Germany was re-elected IIHF president.âCP
