Pushed by Chelsea Valois, the Olympic gold medallist saw off stiff challenges from the Swiss and German bobs to take her third win from three so far this season.
Humphries also won at Park City and Lake Placid, meaning she has a maximum 675 points and an 81-point lead over her nearest rival Sandra Kiriasis in the overall standings.
Kiriasis and her partner Berit Wiacker of Germany could only manage third at the Whistler Sliding Center, behind second-placaed Swiss duo Fabienne Meyler and Elisabeth Graf.
