Canada won its fifth consecutive Memorial of Ivan Hlinka gold medal, 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 the Finns 4-0 on Saturday in Piestany, Czech Republic, to claim the U-18 tournament for the 17th time since it was introduced in 1991.
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.
Tri-City American goalie Eric Comrie played for Team Canada, backstopping Canada to a win over Slovakia on Wednesday.
