The Calgary Stampeders, naturally, remain at the top of the TSN.ca CFL Power Rankings, ahead of the rising B.C. Lions.
The Lions jumped from four to two this week, having taken a head-to-head matchup against the Edmonton Eskimos. The Lions, Eskimos and Winnipeg Blue Bombers are Calgary's top challengers, but they continue to battle for supremacy on their own tier, resulting in frequent changes in spots two, three and four.
