It was a record-setting third straight dual moguls world title for Bilodeau. Kingsbury, from Montreal, had defeated Bilodeau, from Rosemere, Que to take the single moguls title Wednesday.
"When we're on the hill ... he's my biggest competitor," Bilodeau said on a conference call. "I'm happy that Canada can have two potential medals every day."
He had the edge Friday, since as leader he got to pick the course he had run before and slipped by his teammate with a score of 18-17.
Dufour-Lapointe, also of Montreal, topped her silver-medal finish at the 2011 world championships by edging Miki Ito of Japan 18-17 in the women`s final. Dufour-Lapointe had to knock out younger sister Justine to get there.
"We were kind of sad we didn't have a chance to be together on the podium," she said.
However, winning her first gold was a major high.
"It's a lot of emotion ... I did my job today," she said.
Justine added she was overjoyed for her sister.
"I’m just so happy for her now,`` she said. ``She is skiing so well and after she won against me I just felt that today was her day. I’m so proud of her."
American Hannah Kearney earned a dual moguls bronze medal for the third consecutive world event. Ito, also the dual moguls runner-up in 2009, lost to Kearney in the moguls final Wednesday.
The Canadian team has won seven medals at the competition, which continues through the weekend. J.F. Houle of Drummondville, Que., Kaya Turski of Montreal, Dara Howell of Huntsville, Ont. and Yuki Tsubota of Pemberton, B.C., were scheduled to compete in slopestyle on Saturday.
Peter Judge, chief executive officer of the Canadian Freestyle Ski Association, has been impressed with the team`s performance.
"The depth of the team has been showed here," he said. "There's a winning tradition ... whatever discipline they're in, they come and expect to medal. `
``They have that expectation based on the history of the sport in Canada."
