Great Britain suffered a second straight loss as number one seeds Canada racked up eight goals without reply in a one-sided 8-0 contest.
Anthony Mantha scored two and assisted in three as Pete Russell’s men did their best against one of the best sides in the world, but the gulf in class was there for all to see.
It took the Canadians three minutes to draw first blood when Mathieu Joseph buried a shot from point with the assist from Adam Henrique.
Goal number two followed ten minutes later as Jared McCann burst forward, sliding his pass to Mantha, who left Ben Bowns beaten and the scoreline was already leaning one way.
Kyle Turris added a third early in the middle period as Tim Billingsley’s skate blew at an inopportune moment, allowing Mantha a free pass in the wide position, where the Nashville Predators applied the finish.
Canada made it four without reply through Dylan Strome with Dante Fabbro increasing the scoring to five in the dying embers of the second period.
Turris’ second within the opening minute of the third period with further goals coming from Sean Couturier and Mantha with his second more than secured a good night’s work.
Bowns, who performed valiantly, made way for Jackson Whistle in the final ten minutes, but the game had long gone as Canada atoned for their opening day loss to Slovakia.
