If you look at the average gross $$ for those 4 Canadian shows, it still beats St Paul (next best Jovi show) ... by almost $250K American PER SHOW.
So next time someone sees a setlist and says "Why Canada?" well this would be why, its quite obvious that the band does really well when they are in Toronto.
Im assuming this is all in USD.
