The 26-year-old Creighton had to settle for fourth in the competition in the United States as Reid edged out compatriot Mellisa Hollingsworth, with quadruple world champion Marion Thees finishing in third.
It was Reid's first World Cup podium, as she beat out Hollingsworth by just 0.03 seconds. Creighton ended up in fourth 0.33 behind Thees, but well clear of her teammate Shelley Rudman, who ended up coming home in seventh.
The one-two was more proof of the strength of the Canadian skeleton team and Reid admitted the quality of the team was pushing the team forward.
Reid said: "Our Canadian programme is really strong and to slide next to athletes like Mel, everyone is pushing everyone to be better every day.
"I had two really good runs yesterday and I knew if I could do what I know how to do, I could do it."
