The 19-year-old from Deux Montagnes, Que., won a men's World Cup moguls singles event Thursday. It left Kingsbury, in his third season on the World Cup circuit, undefeated this year, having won all four events thus far.
"I didn't push my max on the speed but on the technical points of skiing I was perfect with no mistakes," he said. "And on the jump I was clean.
"Those were my keys today.''
American Patrick Deneen was second while Phillipe Marquis of Quebec City was third.
The Canadian team secured a third medal as Montreal's Justine Dufour-Lapointe claimed the silver in the women's event.
"That was awesome because those are my best friends and they were on the podium with me," Kingsbury said.
The bronze medal was significant for Marquis as it marked his first-ever podium finish.
"It's four-for-four for Mikael and being on the podium with him is a good sign for me and what's coming," Marquis said. "It was a really big day.
"It was a pretty tough course, everybody was skiing pretty good and I managed to pull it out at the end of the day. I'm so stoked.''
Montreal's Alexandre Bilodeau finished fifth, one spot ahead of Marc-Antoine Gagnon of Terrebonne, Que. Eddie Hicks of Langley, B.C., was ninth.
American Hannah Kearney won the women's event to remain undefeated this season. Dufour-Lapointe, 17, finished second overall ahead of Nikola Sudova of the Czech Republic.
The race marked Dufor-Lapointe's first podium finish in a singles event.
"I was able to ski calm and concentrate on my cues," Dufour-Lapointe said. "Everything seems to be coming together in singles and I'm really happy.
"I'm trying to stay more consistent in my skiing. Sometimes I get too excited for nothing but now I have more experience and have learned a lot to know myself better.''
Older sister Chloe Dufour-Lapointe, 20, finished fifth.
