Canada opened the Four Nations Cup women's hockey tournament with a 6-0 win over Finland on Tuesday.

Jayna Hefford of Kingston, Ont., paced Canada with two goals and an assist in the game at Lake Placid, N.Y. Hayley Wickenheiser of Shaunavon, Sask., contributed a goal and two assists.

Sarah Vaillancourt of Sherbrooke, Que., Toronto's Jennifer Wakefield and defenceman Jocelyn Larocque of Ste. Anne, Man., also scored for Canada.

Winnipeg's Jennifer Botterill collected two assists. Charline Labonte of Boisbriand, Que., stopped 12 shots for her 11th career shutout for Canada.

Canada's penalty killers held Finland to a handful of shots on five power-play opportunities.

The score would have been more lopsided against Finland, the bronze medallist at the world championship behind runner-up Canada, if not for the work of goaltender Noora Raty.

Canada will play the United States on Thursday evening and Sweden the following day. The semifinals and final take place on Sunday.

The United States beat Sweden 5-2 in Tuesday's late game.

Canada has won this annual international tournament for four consecutive years, but the U.S. is the reigning world champion with back-to-back victories over Canada to conclude the world championship in Harbin, China.

Canada raced out to a 3-0 lead after the first and added two late goals to pad the score.

Hefford scored her second of the game and 110th of her career off the rush with Wickenheiser and Caroline Ouellette at 18:53 of the final period.

Larocque, making her national team debut, banged in a rebound for her first career goal at 19:27 of the third.
