LONDON, Ontario (AP) Patrick Chan overcame a couple of mistakes to win the men's short program by a large margin at the Canadian Figure Skating Championships on Friday night.

The reigning world silver medalist from Toronto scored 90.14 points, despite putting a hand down on a triple flip, then doubling a planned triple flip on the back end of a combination.

Chan took a commanding lead on Vaughn Chipeur heading into Sunday's free skate. Chipeur earned 78.87 points with his clean program.

In the women's competition, five-time defending champion Joannie Rochette fell during her short routine and trailed Cynthia Phaneuf heading into the long program. Phaneuf scored 66.30 points to win the short program ahead of Rochette, who received 64.15 points after her spill.
