CALGARY - The mayors of Montreal and Regina have a friendly bet going over whose team will win the Grey Cup.

Regina's Pat Fiacco and Montreal's Gerald Tremblay have wagered two pairs of season tickets on this year's CFL championship game between the Saskatchewan Roughriders and Montreal Alouettes.

The mayor whose team loses will have to buy the tickets, and the winner gets to donate them to charities of his choice.

The losing mayor must also wear the winning team's jersey at a city council meeting and fly the winning team's flag in front of city hall for a day.

The 97th Grey Cup game will be played this Sunday at 5:30 p.m. Regina time.
