CALGARY, ALTA -- Defencemen Rob Blake of the Los Angeles Kings and Steve Chiasson of the Hartford Whalers, and forwards Geoff Sanderson and Keith Primeau, also of Hartford, were among seven players added to Canada's World Hockey Championship roster on Monday, Canadian Hockey announced.

Also named to the team by general manager Bob Clarke were: forward Chris Gratton and goaltender Rick Tabaracci, both of the Tampa Bay Lightning; as well as Calgary Flames defenceman Todd Simpson. The additions bring to 13 the number of players Clarke has chosen to play for Canada at the World Hockey Championship, which goes from April 26 -- May 14 in Helsinki and Turku, Finland.

On Sunday, Clarke named Calgary's Jarome Iginla, San Jose Shark Jeff Friesen, Canadian National Team member Dean Evason, as well as goalie Eric Fichaud, centre Travis Green and defenceman Bryan McCabe, all of the New York Islanders.

The team will be selected and managed by Clarke, Bob Gainey, the Dallas Stars GM, and Pierre Gauthier, GM of the Ottawa Senators. The three GMs also will manage Team Canada at the 1998 Winter Olympics in Nagano, Japan.

Canada's World Championship entry will be coached by Andy Murray, head coach of Canada's National Team, along with assistants Mike Johnston, who is associate coach and GM of the National team, and Wayne Cashman, assistant coach of the San Jose Sharks. The club opens a mini-camp on Thursday in Winnipeg to prepare for the World Championship, and Team Canada will play two pre-tournament games at the Winnipeg Arena on April 19 and 20 before flying to Finland.

Canada will carry a roster of 23 players (three goalies, 20 skaters) at the World Championship, which begins for Team Canada in Turku on April 26 against Norway. Clarke hopes to have 16 NHL players chosen in time for the pre-camp in Winnipeg and will also use four members of the full-time National team -- defenceman Brett Clark, forwards Steve Junker and Jason Young, and Evason.
