Anthony Mantha scored three goals, all set up by linemate Jonathan Drouin, as Canada got the world junior championship started with a one-sided 7-2 victory over Germany on Thursday.
Josh Anderson, Bo Horvat, Sam Reinhart and Nic Petan also scored for Canada, which is 12-0 all-time against Germany at the IIHF under-20 event.
Dorian Saeftel and Janik Moser had first-period goals for the Germans.
The announced crowd of 1,831 was mostly fans dressed in Hockey Canada jerseys at the 5,800-seat Isstadion, the smaller of the two tournament venues, but they made plenty of noise.
The ice was mostly tilted toward the German zone, although they caused Canada some shaky moments in their few meaningful incursions into the attacking zone.
Germany even got the first goal as Lennart Palausch won a faceoff in Canada's end and defenceman Saeftel threaded a pass through traffic and past Jake Paterson only 1:33 into the game.
