The Calgary Stampeders have returned to the top spot in the TSN.ca CFL Power Rankings, surpassing the injury-plagued Hamilton Tiger-Cats.
After a relatively slow start to the year, the Stamps have won four straight, by a cumulative margin of 79 points.
A decisive win over Toronto also helped lift the Edmonton Eskimos from four to three, and Ottawa's rout over Saskatchewan earned them a move up from seven to six.
