Niederreiter was a minus-1 and had one shot in 11 minutes, 29 seconds of ice time. So far in the tournament, he has one assist in five games and is a plus-1 overall with five shots on goal.
Canada scored twice in the first frame. The first goal came at 2:33 from Brad Marchand, whose four goals through five games are the most of any player in the World Cup. Steven Stamkos doubled Canada's lead with a goal at 13:20.
Tatar cut Canada's lead in half in the second period when he scored off a Dennis Seidenberg rebound, but Canada added another tally off the stick of Patrice Bergeron halfway through the third period to make it 3-1. Sidney Crosby assisted on Marchand and Bergeron's goals.
Canada's win in game one puts the team on track to win the World Cup of Hockey, which it can do if it defeats Europe Thursday night. Game two of the best-of-three finals will be at 7 p.m. and broadcast on ESPN2.
