He was very pleased with the results.
Kingsbury defeated Canadian teammate Alex Bilodeau for the world moguls title Wednesday, while Justine Dufour-Lapointe took bronze in women's competition.
Kingsbury, the reigning World Cup champion and season leader from Deux Montagnes, Que., posted a dominant score of 27.59 in his final run. He said it might have been the highest score of his career.
His winning run included a double twisting back flip off the top jump and a cork 1080 — or triple twisting off-axis trick — off the second.
"It was the first time I did the cork 1080," Kingsbury said. "Usually I do a back double full (a straight back flip with two twists) and a 720 and today I did a back double full and a cork 1080 which were the biggest tricks of the competition.
"I'm pretty confident to do it pretty much everywhere, so it's pretty good to have that in my back pocket."
Bilodeau, the Vancouver Olympic champion from Rosemere, Que., and world champion in 2011, finished second with a score of 26.95.
"It's very hard for me today," Bilodeau said. "I know the skiing I delivered. I've seen it on video. It wasn't enough for the judges today, they didn't think I was the top skier and it's all in their hands.
"The only thing I can say is congratulations to Mik."
Patrick Deneen of the United States, the 2009 world champ, took third.
Kingsbury said he didn't feel any pressure to unveil the new jumps with Bilodeau threatening to knock him off the top of the podium.
"I didn't put too much pressure on myself," he said. "I was kind of in the driver's seat. The other guys had to make mistakes to come to get me and that worked well for me."
Philippe Marquis of Quebec City was 15th and Marc-Antoine Gagnon of Terrebonne, Que., finished 17th.
In women's competition, American Hannah Kearney topped a good first run with a stellar second effort worth 26.70 points for the women's title. She's the reigning Olympic and World Cup moguls champion and season leader.
Miki Ito of Japan was second with 24.92 points and Montreal's Dufour-Lapointe was third with 23.48. Both had better performances in the first round setting up the final six skiers.
Dufour-Lapointe, 18, fell in the first round of Tuesday's eliminations, but was saved by a new world championship format that gave everyone in the field who finished lower than 10th position a second chance to earn a spot in the 18-woman finals.
"It was not easy," she said, "And I'm so happy about my medal today, but in fact it's not the medal so much as the path that I took to get it. The path was tough but I made it."
Montreal's Chloe Dufour-Lapointe finished eighth, Audrey Robichaud of Quebec City was 11th and rookie Andi Naude of Penticton, B.C. ended up 12th.
Both Bilodeau and Justine Dufour-Lapointe earned provisional nominations to Canada's 2014 Olympic team. Kingsbury has already met the Olympic qualifying criteria.
