Canada bounced back from a loss to the United States in the opening game at the world championship by trashing Korea 10-0 on Sunday.
Also Olympic champion Russia again displayed its offensive might in a 7-0 rout of Austria.
After losing 5-4 to the U.S. in a penalty shootout, Canada was ruthless against Korea, a championship newcomer in a Group B game in Herning.
Captain Connor McDavid scored his first goal of the tournament and added two assists, and Tyson Jost scored twice and had an assist to lead Canada. Pierre-Luc Dubois and Joel Edmundson also had a goal and two assists each.
“We did everything we had to,” McDavid said.
Colton Parayko, Ryan O’Reilly and Dubois netted a goal each in the span of 1:25 early in the second period to jump to a 5-0 lead.
The Canadians scored six goals in that period, forcing Korea to pull Canada-born goaltender Matt Dalton.
Ryan Nugent-Hopkins and Brayden Schenn also scored for Canada.
Goalie Curtis McElhinney made 25 saves for the shutout.
Canada next faces host Denmark.
“I think it’s gonna be a very good game, they’re a good team, they’ve got a lot of talent,” McDavid said. “I’ve seen the crowd is getting into it and the fans, they can have a big impact on the game.”
After losing to Finland 8-1 on Saturday, Korea must improve to avoid relegation.
In Group A in Copenhagen, Mikhail Grigorenko scored twice and Artyom Anisimov, Alexander Barabanov, Kirill Kaprizov, Maxim Mamin and Ilya Mikheyev added one apiece for Russia.
In its championship opener, Russia also dealt France a 7-0 defeat.
