This gave the North Americans an unassailable 2-0 lead in the best-of-three final series to mean there is no need for a decider.

But, despite more raucous home support in the Air Canada Centre, the hosts left it late after an uncharacteristically sluggish performance. 

Slovakian defenseman Zdeno Chara had put the composite European side ahead in the first period as goalkeeper and fellow countryman Jaroslav Halak proved comfortable with anything Canada could throw at him.

The team, who had already exceeded expectations to reach the final series, had said they would need a near-perfect game to stand a chance - and they were producing one.

Eventually, however, their formidable defence was worn down as the hosts underlined their champion quality.

First, Patrice Bergeron scored the tying goal on a deflection with 2:53 left in the game.

Winger Brad Marchand then scored a short-handed goal with 54 seconds left in regulation time to secure the victory to follow a 3-1 opening win.

It means Canada defend the crown they won the last time the World Cup of Hockey was played in 2004.

They won all six matches in the tournament and outscored their opponents 24-8 to add the World Cup title to their world and Olympic ones.

Canadian goalie Carey Price made 32 saves to help seal the victory, while superstar Sidney Crosby was named Most Valuable Player.
