Sporting painted-on upper-lip hair in support of cancer awareness, Kaillie Humphries and Chelsea Valios raced down the Utah Olympic Park course to claim their second straight victory in the series.
The Canadians finished two runs in a combined time of 1 minute, 39.49 seconds to snatch gold from Germany's two entrants.
“You've got to have fun out there,” said Humphries, who teamed up with new brakeman Valios for the win.
“Chelsea has tons of potential,” Humphries said. “It's real exciting as we get closer and closer to Sochi. But I'm fairly new. I still make mistakes, so I'm trying to get as consistent as possible.”
Sandra Kiriasis and Franziska Bertels took silver ahead of fellow Germans Cathleen Martini and Stephanie Schneider.
Great Britain's bobsleigh came in ninth.
