Thomas Chabot got Canada to within one score midway through the second period as he blasted a rebound from the backside of the net past goaltender Joseph Woll during a 5-on-3 power play.
Canada gained a new sense of confidence after Chabot's goal and was aggressive down the ice, but it could not find the equalizer. The U.S. withstood the pressure and forward Jeremy Bracco lit the lamp on a rebound before the middle frame ended to extend the Americans' lead back to two..
Special teams was the difference in the end, as Canada was only able to score on one of its six man advantages. Canada still has the best power-play percentage in the tournament, converting on 47.37 percent of its chances (9-for-19).
Colorado Avalanche prospect Tyson Jost of Canada recorded three shots on goal and also had two penalty minutes.
Team Canada will battle the Czech Republic on Monday at 6 p.m. in the quarterfinals.
