The following list from Pollstar Magazine list the top grossing arenas world wide. The figures are for all events hosted by the arenas excluding professional sports. IE, No hockey basketball arena football etc.
The list basically counts concerts, tradeshows, conventions etc.
I am particularily proud of #52, Saskatoon. At 11 300 seats it is one of the smaller arenas on the list and in a city of 230 000 one of the smaller cities.
Way to go Saskatoon. Keep the concerts coming
