the Bell Center has 21,273 capacity. air Canada center is 18,800. when montreal's/toronto's next arenas comes due for construction (and that won't be for some time I know) how far do you think they could take it? I think that habs/leafs fans would easily sellout a 25,000 seat arena. maybe even up to 27-28,000. It would be so cool to go to regular season NHL games with +25k fans. is ~20,000 is the natural limit for NHL arenas? because that seems to be where its at in our era. of course these mega outdoor (WC's) and indoor games (gelsenkirchen) are getting people to rethink this.
