Huge revenge spot for British Columbia. The Lions just lost to Montreal, 21-16, on the road three weeks ago. The Lions outgained the Alouettes in that game and had the ball more nearly 10 more minutes than Montreal. 
Another key factor for backing BC is the CFL has suspended Montreal QB Vernon Adams Jr. for this game. Adams has been a big reason for the Alouettes' resurgence. 
The Lions are coming off a pair of victories against Ottawa. They are 3-0-1 ATS in their last four games while giving up just 11.5 points a game during their last four matchups. 
BC has owned Montreal when playing at home covering in 17 of the past 21 times there.
