Montreal native Francois-Louis Tremblay and Olivier Jean of Lachenaie, Que., won gold and silver respectively on Saturday in the men's 500-metres at the season-opening short track speed skating World Cup competition.

Tremblay rocketed from the start and was unchallenged until the finish in the four-man final, clocking 42.139 seconds. Jean was second in 42.271 while Kim Byeong-jun of South Korea was third.

The Canadians capitalized on a new rule for this season with the starting positions determined by the fastest times from the previous round. Previously, the start positions were determined in a draw.

``It's great to start the season on such a strong note,'' Tremblay said. ``The key for me today was to skate fast through every round (quarter-finals, semifinals, final). That way, I guaranteed myself the best starting position on the line. In the final, I just did the same as in the previous round by gaining the lead right from the start.''

Jean is making his World Cup debut this weekend. He kept second spot from start to finish in the final.

``I guess I'm a little surprised to be on the podium,'' said Jean, 22. ``I just feel in great shape right now and as I went through each round I gained more and more confidence. The final was a very fast race and I was focusing on just maintaining my position.''

Charles Hamelin of Ste-Julie, Que., was disqualified in the semifinal.

In the men's 1,500, world-record holder Ahn Hyun-soo clocked 2:20.585 to lead South Korea to a 1-2 finish, while Lee Ho-suk, the Olympic silver medallist, finished second.

Marc-Andre Monette of Pointe-aux-Trembles, Que., and Canadian champion Mathieu Giroux of Montreal, also World Cup rookies, reached the final and placed fourth and fifth respectively.

In the women's 500, Kalyna Roberge of Ste-Etienne-de-Lauzon, Que., was second in the B final for sixth overall while Anouk Leblanc-Boucher of Montreal and Anne Maltais of Quebec City were eliminated in the quarter-finals.

Meng Wang led China to a medal sweep in the final.

In the women's 1,500, Montreal's Nita Avrith and Raphaele Lemieux of Riviere-du-Loup, Que., were eliminated in the semis. Jin Sun-yu led South Korea to a 1-2-3 finish in the final.
