The Stamps are 5-0 at McMahon this season and have won 10 straight at home dating back to Aug. 18, 2012. Coincidentally, it was Toronto that handed the Red and White its most recent loss at McMahon.

The Argos also had a come-from-behind win in Week 12 as they rallied to down the Saskatchewan Roughriders 31-29 in Regina. Toronto is 4-1 on the road this season.

Calgary is unbeaten against East Division clubs so far this season with five wins in as many tries including a 35-14 victory at Toronto on Aug. 23. The Argos are 3-3 against the West.
