Canada's Olympic ice dance champions Tessa Virtue and Scott Moir have some huge ground to make up if they're to capture their first ISU Grand Prix Final victory.

Virtue, from London, Ont., and Moir, from Ilderton, Ont., are in second place a full five points behind the leaders after Friday's short dance in Quebec City thanks to an uncharacteristic fall by Moir.

The 24-year-old caught his blade on Virtue's and went down on his backside before quickly popping back up and racing to catch up with Virtue. The gold medallists at the 2010 Vancouver Olympics finished with 71.01 points.

Reigning world champions Meryl Davis and Charlie White of the U.S. are the leaders after scoring 76.17.

Nathalie Pechalat and Fabian Bourzat of France are third with 68.68.

Kaitlyn Weaver and Andrew Poje of Waterloo, Ont., are fourth with 66.24.

Kostner leads ladies

Carolina Kostner of Italy scored 66.43 to lead the women's singles short program. Japan's Akiko Suzuki was second with 61.30, while Alena Leonova of Russia scored 60.46 to sit third.

Earlier Friday, Katherine Bobak and Ian Beharry captured a silver medal in junior pairs, to continue their swift rise up the figure skating ranks.

The 17-year-old Bobak and Beharry, 19, earned a score of 152.65 points overall, clinching silver with their second-place performance in the free program.

Sui Wenjing and Han Cong of China won the gold with 160.43 points, while Americans Britney Simpson and Matthew Blackmer scored 146.35 for bronze.

Bobak and Beharry, both from Guelph, Ont., have only been competing together since last February, but earned a gold and silver in their two Junior Grand Prix events to earn a berth in the Final.

"I think both of our skating styles are really similar, that's what everybody said right off the bat in our first tryout," said Beharry, who also has a job as a Zamboni driver.

"I would say he's got a really calm personality so even when I'm a little high maintenance it always balances each other out, I guess," said Bobak, a Grade 12 student.

Their medal was Canada's first in pairs at the Final since Jessica Dube and Bryce Davison won gold in 2003.

"And to do it in Canada, couldn't ask for anything else," said Beharry.
