Canada won its fifth straight Ivan Hlinka Memorial hockey championship with its most complete game of the tournament, using a dominant forecheck to tire out a fading Finland team.
Nathan MacKinnon scored three goals, including two on the power play, as Canada defeated 4-0 on Saturday to claim the under-18 tournament for the 17th time since it was introduced in 1991.
"That was our best game from start to finish. Everybody bought in," Canada coach Todd Gill said.
"Our slogan was 'I am willing,' and everybody was willing tonight and it showed."
MacKinnon finished the tournament with five goals and six assists in five games.
Curtis Lazar also scored for Canada, while Zachary Fucale made 23 saves for the shutout.
The game was scoreless after the first period, but Gill could sense the Finns were being tired out by Canada's forecheck and ability to cycle the puck.
Canada took advantage by scoring three goals in the second period while outshooting Finland 22-9. Canada outshot Finland 44-23 in the game.
Finland had a chance to get back in the game when Nicholas Ritchie was assessed a five-minute major and a game misconduct for a check to the head 2: 10 into the third period.
"It was a good hard hit," Gill said of the penalty. "The kid fell and skated off real quick but by that time [the referee] had made his decision."
The Canadians killed off the major, then shortly after MacKinnon scored his second power-play goal of the game to suck the rest of the life out of the Finns.
Earlier Saturday, Sweden beat the Czech Republic 2-1 in the bronze-medal game.
