In the women's gold medal game, defending champions Sweden, undefeated in the championships until Saturday, were beaten 7-4 by Canada.
The Canadian women jumped on the Chinese rink with two points in the first end and three more in the third for a 5-1 lead. The Scots fought back after this and forced the game into an extra end when a single point steal in the tenth end levelled the score at 5-5.
Canadian skip Tardi said: "It's an unbelievable feeling. I don't even know how long I've been dreaming about this moment, and to have it finally come true is just unbelievable", said Tardi. "I can't believe it".
"They're all great shooters on the other team, hats off to them", said Tardi. They made a really good comeback - good on them. They've been working so hard all season. We let ourselves down in the fifth end, but after that I still think we played a pretty good game.
"We just weren't as sharp as we'd been all week", Whyte admitted. Unfortunately, we didn't turn out and shoot the lights out.
"They put us under a lot of pressure and we really struggled to make twos".
"The boys played really well throughout the whole week and really made my job easy. I don't know what happened - whether it's nerves, but the Canadian boys came out firing, so fair play to them and well done".
Irish group wanted over more alleged scams in Queensland
Police say in one case, an elderly man lost more than $25,000 when he paid men to fix his roof but they never finished the job. Some of the Irish scammers who've brazenly ripped off Queenslanders have fled Australia, while others have gone to ground.
"It's a goal to force them to one and we got the end-goal that we wanted".
Stopera (Briarcliff Manor, N.Y.) and his team of Luc Violette (Lake Stevens, Wash.), Ben Richardson (Issaquah, Wash.), Graem Fenson (Bemidji) and Jonathon Harstad (Duluth) gave up a big end late in the game that fueled the 7-4 win by Jan Hess and the Swiss men.
With Canada's women also taking gold earlier, this completed a notable double.
"This is indescribable and I feel wonderful right now", she said following the win.
"I'm just feeling amazed, I guess", said the 19-year-old skip. "It's the best game I've ever seen them curl, probably the best game I've ever seen curled by a junior women's team - ever". "Whenever they had the hammer we wanted to keep them close to one".
At 4-2 going into the seventh, Scotland needed to start making up the ground, but after a poor draw with his penultimate stone, Whyte couldn't use the hammer to prevent a Canadian steal of one.
