The United States tried to keep up with rival Canada on Tuesday at the world championships. And the Americans did -- until the final minute.

Dany Heatley scored the winning goal with 46.8 seconds left to lift Canada to a 5-4 victory in Halifax, Nova Scotia.

It was Heatley's second goal of the game.

"We didn't want to wait until the last minute, but we'll take it," said Heatley, who scored his fifth and sixth goals of the tournament.

"In the last minute of periods, we hurt ourselves," U.S. and Lightning coach John Tortorella said.

Meanwhile, U.S. captain and Lightning center Jeff Halpern injured his right knee during the game, Tampa Bay spokesman Bill Wickett said.

Halpern is not expected to play in the Americans' next game, set for Thursday. He will have a full evaluation today, Wickett said, and the team plans to issue a full report.

For the Canadians (3-0), Brent Burns, Jonathan Toews and Derek Roy also scored, and Cam Ward stopped 29 shots.

"We played really hard right to the end," Canada's Ryan Getzlaf said. "We take pride in those kind of wins. We were raised that way."

Zach Parise, Patrick O'Sullivan, Dustin Brown and Jason Pominville scored for the Americans (2-1), who were praised by Tortorella. "I thought they played their a---- off."

After the Americans fell behind early, Parise and O'Sullivan scored 2:17 apart to cut the lead to 3-2.

"I think we showed a lot of people that we're capable of playing at the same level as these guys," O'Sullivan said.

The Canadians extended their lead to 4-2 on a goal by Roy at 3:29 of the third period. He slammed a pass by Shane Doan past Craig Anderson, who replaced Tim Thomas after the second intermission.

"We don't necessarily rely on the pretty play; we don't rely on one individual guy," Doan said. "As a unit we're pretty solid, and we can count on our depth. If it takes 60 minutes, it takes 60 minutes."

Brown and Pominville scored 36 seconds apart on the power play to erase that lead.

In Quebec City, Capitals teammates Alex Ovechkin and Sergei Fedorov each scored, helping Russia (3-0) defeat Denmark 4-1.
