Marie-Philip Poulin scored four times to pace Canada to a 13-0 win over Switzerland at the women's world hockey championship Wednesday.
Canada was minus captain Hayley Wickenheiser and assistant captain Caroline Ouellette. Both players were scratched from the lineup prior to the game with upper-body injuries. Head coach Dan Church said they were "day-to-day."
Their absence forced Church to be creative with his line combinations. Canada's forwards made the most of their extra ice time.
Brianne Jenner scored twice and Jennifer Wakefield had a goal and two assists. Rebecca Johnston, Natalie Spooner, Sarah Vaillancourt, Meaghan Mikkelson and Haley Irwin also scored, with Jayna Hefford contributing a short-handed goal.
Charline Labonte stopped 16 shots for the shutout.
Poulin tied a record for the most goals in a single game scored by a Canadian player. Three others have scored four, including Hockey Hall of Famer Angela James.
Poulin's third goal was awarded after a review. She backhanded the puck upstairs on Swiss goalie Sophie Anthamatten and raised her arms in celebration, only to watch play continue. Officials examined the play on the next whistle and awarded Poulin her third goal.
Anthamatten started strong, but she and her teammates were eventually worn down by Canada's superior size, speed and puck possession skills. The goaltender was replaced by Dominique Slongo with less than four minutes remaining in the game. Canada outshot Switzerland 79-16.
Canada topped Pool A at 2-0 ahead of Finland and the United States tied at 1-1 and the Swiss at 0-2. The Americans doubled the Finns 4-2 on Wednesday. Canada concludes the preliminary round Friday against the Finns.
Russia downed the Czech Republic 3-1 to lead Pool B at 2-0. The Czechs were second at 1-1. Sweden downed Germany 3-2 in overtime to sit third at two points ahead of Germany with one.
The top two countries in Pool A get byes to the semifinals while the bottom two face the top two from Pool B in the quarter-finals. The bottom two teams in B fall to the relegation round.
Switzerland won bronze at last year's world championship in Burlington, Vt., for that country's first medal in tournament history.
Goaltender Florence Schelling can take much of the credit for that medal, but she was also scratched from her country's lineup.
Instead of their usual neutral-zone trap, the Swiss forechecked aggressively to start the game and attempted to poke holes in the Canadian coverage with stretch passes.
But their attempts to keep the score close faded in the face of Canada's fitness and puck skills.
