Brad Bowden, Kevin Rempel and captain Greg Westlake combined for three goals and eight points as Canada cruised to an 8-0 victory over South Korea on Sunday in preliminary-round action.
Bowden scored twice and set up two more, Rempel added a goal while Westlake tacked on three assists.
"Everyone on our team has a role that they have to fill sometimes, some nights it changes depending on how the games are going but tonight I felt like it was our line's job to get some energy going and to put that first goal in," said Bowden. "Thankfully we did that."
Canadian netminder Corbin Watson only had to make 10 saves to earn the shutout.
Tyler McGregor also had a pair of goals for Canada (1-0-0), while Adam Dixon scored once and assisted on two others. Marc Dorion and Ben Delaney rounded out Canada's offence.
Man-Gyun Yu turned away 14-of-22 shots for South Korea (0-1-0).
Bowden opened the scoring at 7:13 of the first period and Dixon made it 2-0 for Canada 28 seconds later.
Dorion put the Canadians up three goals before the first intermission.
Delaney struck 2:02 into the second period and then Canada blew the game open with three goals in a span of 2:42 to make it 7-0 after 40 minutes.
McGregor scored his first of the game at 10:10 while on the power play and Rempel followed at 12:32. McGregor then added his second of the period just 19 seconds after.
Bowden rounded out the scoring at 9:08 of the third period with another power-play goal.
The Canadians went 2 for 3 on the power play and kept out of the penalty box for the entire contest.
Canada recently hosted its team selection camp, replacing some veterans with new faces. A victory over South Korea alleviated some of the nerves for those lacking international experience, according to Bowden — an alternate captain.
"For some of the new guys I think (winning) helps them relax a bit," said Bowden. "I know some of them had some nerves at the start but they loosened up against Korea."
Earlier — in a rematch of the gold-medal game from the 2014 Sochi Paralympics — Declan Farmer scored with 1:45 left in the third to lift the U.S. over Russia 3-2.
Brody Roybal and Kevin McKee also scored for the Americans (1-0-0), who got an 18-save outing from goaltender Steve Cash.
"It was an exciting first game, not just for the tournament, but for our season in general," said U.S. coach Jeff Sauer. "Our newcomers learned a lot today against a strong Russian team. We're glad to get the win and ready to improve next game."
Evgeny Petrov and Vasily Varlakov supplied the offence for Russia (0-1-1) while Vladimir Kamanstev stopped 17 shots in the loss.
Canada will face Russia on Monday in preliminary-round action while the U.S. plays South Korea.
"I can feel this fire in the change room, guys are hungry now and got a taste of our first win," said Bowden. "Now we're going to be able to take the next step forward and play an even better team with that same energy. It's a very cool feeling right now."
