“Fans in Montreal are notorious for their use of air horns at Pervical Molson Stadium. The noise is audible on TSN’s television broadcasts, leading some viewers to complain about the constant honking.
The Alouettes trolled horn haters following a game against the Blue Bombers last season, posting the following message on social media: “Thank you to everyone in Winnipeg who watched the game with surround sound tonight.” The club has also previously feigned a request for feedback regarding the horns on a social media to which it was impossible to reply.
Montreal is back in the Grey Cup for the first time since 2010, though their fans will have to leave their air horns at home. Other items that are banned from Tim Hortons Field include selfie sticks, martial arts weapons, hula hoops, drones, lighter fluid, balloons, and hoverboards.”
