Great Britain were beaten 8-0 by the world's top seeds Canada in their second game at the World Championship in Slovakia.
Ben Bowns produced some world-class saves throughout the game, but Canada secured their first win of the tournament following their opening-day loss to Finland.
After early pressure, Canada took the lead at 2:42 with Mathieu Joseph scoring a rebound on the doorstep.
Ben Davies, Liam Kirk and Robert Dowd had chances but the Canadians remained on top - and a great skate from Jared McCann set up Anthony Manta in front (12:33).
A drive to the net by Kyle Turris saw Canada score their third (22:45) and after two chances for Ben Lake, Dylan Strome netted on the powerplay after a massive scramble around the net (27:05).
Bowns pulled off two outstanding saves in quick succession before a bullet of a shot from right point by Dante Fabbro increased Canada's lead (39:37).
Turris scored his second with a beauty of a top-shelf finish from close range (40:57), while Sean Couturier netted on the rebound on the powerplay (46:46).
Robert Lachowicz says atmosphere around Great Britain camp like nothing he has known before
Mantha scored his second from a close-range rebound at 50:27, before Jackson Whistle replaced Bowns for the final nine and a half minutes.
Bowns said: "We have left the ice disappointed as we know we can do better, but these are the best team in the world.
"They were quick all over the ice and it was an experience to play in this game against such a good side.
"Obviously, when we took to the ice we could not think about that as we had a job to do, but looking back now it was an experience.
"We can take heart from many aspects of these two games and we have some big matches coming up for sure."
