The Canadian women are off to a strong start at the world junior curling championships, but the men are struggling early on in Flims, Switzerland.

Alberta's Kelsey Rocque won both her games Wednesday on the first day of the round robin.

Rocque and her Edmonton team of Keely Brown, Taylor McDonald and Claire Tully stole four ends, including a single in an extra end, to score a 7-6 victory over Czech Republic in the first draw.

Later Wednesday they fell behind Italy's Veronica Zappone 5-3 after the Italians stole a point in the seventh, but rallied for three points in the eighth and went on to win 8-6.

"It was rough, I struggled a bit," said Rocque about the first five ends against Italy. "We just weren't curling like we could."

She felt the three points in the seventh gave the Canadians some momentum.

"We started making some shots. You could see a change in our attitudes," Rocque said. "We started curling a little better and we had some confidence back."

On the men's side, the Winnipeg team of Braden Calvert, Kyle Kurz, Lucas Van Den Bosch and Brendan Wilson lost two close games on the first day of competition.

The Canadians lost their first game 8-6 to the 2013 silver medallists from Russia. Canada was leading 6-5 after nine ends, but Russia's Sergey Glukhov was able to score three for the 8-6 victory.

Calvert followed with a 6-5 loss to Sweden. Calvert stole one in the ninth end to lead 5-4, but Sweden's Fredrik Nyman took a deuce in the 10th.

"We were just on the wrong side of the inch all day, and we weren't as sharp as we needed to be today," said Calvert after the match. "We're just going to sharpen up and have a good practice on the sheet we'll play tomorrow and we'll be good."
