Aside from the fact that the real issue is that for events like concerts the arena only gets a very small portion of the revenue (ie. they essentially rent out their building for the night to a promoter).....can someone tell me where these 130 concerts a year are going to come from? That story says that the ACC has over 200 event nights.....about half being the more profitable "we own the team so we keep all of the revenue" Raptors/Leafs type of events...so, they have, lets say, 100 or so concerts.
Is the "business plan" of this arena that they will take all of the concerts out of the ACC and create 30 more events?" or is it "there are 130 concerts/events that bypass Toronto every year because the ACC {plus SkyDome, Ricoh, other arenas, other concert halls} can't accomodate them"?
Whichever one of those it is....they are both headshakingly implausible.
BTW...without giving it too much thought, I can think of 4 NHL sized arenas in Canada that were built with private money....there may be more but I can get to 4 without google.
