TORONTO -- Arizona Coyotes prospect Max Domi helped lead Canada to its record 16th world junior hockey title and first since 2009, scoring a goal and adding two assists in a 5-4 victory over Russia on Monday night.
"That was a once-in-a-lifetime opportunity, and we took advantage of it," Domi said about winning at home.
Zach Fucale made 26 saves for Canada.
Duclair scored 23 seconds into the game, and Paul made it 2-0 at 2:32, chasing Russian goalie Igor Shestyorkin. Yudin scored for Russia midway through the first.
McDavid, the Erie Otters star expected to be the top pick in the NHL draft, made it 3-1 early in the second, and Domi and Reinhart increased the lead to 5-1.
Russia countered with three goals -- two on power plays -- in a 3:16 span.
"We were able to brush it off," McDavid said. "We're world junior champions. It's joy. Right now, this is just absolute joy."
Canadian Prime Minister Stephen Harper was in the crowd of 19,014 at Air Canada Centre.
"Congratulations to TeamCanada on their outstanding performance tonight. You've made your country extremely proud," Harper tweeted after the victory.
Russia won the last of its 13 titles -- nine as the Soviet Union -- in 2011.
"It was 5-4," Goldobin said. "Just one goal. And we had the whole third period to score. We started pretty badly. We allowed two goals, weak goals. But we have a great team."
In the third-place game, Slovakia beat Sweden 4-2.
In the semifinals Sunday, Canada beat Slovakia 5-1 and Russia topped Sweden 4-1.
