Canada crushed Britain 9-3 to win the men's Winter Olympic curling title for the third successive time and complete a golden double after their women also triumphed in Sochi.
Led by skip Brad Jacobs, the Canadians were far too clinical for a British team seeking a first men's Olympic title since 1924.
With the match realistically out of reach after a series of mistakes, British skip David Murdoch conceded after the eighth of the 10 ends.
Canada is home to the majority of the world's curlers but it is the first time they have won both women's and men's titles at an Olympics.
Sweden earlier beat China 6-4 to take the bronze, clinching the game in an extra end.
