Enduring the minus-30-degree wind-chill factor, more than 1,000 fans cheered and screamed as the five-time Grammy winner, 44, ran onto a makeshift stage wearing a white torchbearer's uniform.
After stopping for a quick photo op, Twain jumped up and down, smiled, waved and lit a ceremonial cauldron to kick off a show.
"There is a lot of excitement surrounding the voyage of the Olympic flame as it makes its way through our beautiful country," the Canadian-born Twain said before the chilly spectacle. "I am proud to be a small part of the flame's journey to its final destination at the games in Vancouver" – where the Olympics will commence Feb. 12.
"I will never forget this honor and cherish the privilege," she said.
