Interesting. Toronto looks like a no brainer on paper, but I just don't know where the fans will come from since most of those 52% avid hockey fans are most likely Leafs fans and are unlikely to jump ship(no matter how bad the Leafs are). And those that are not leafs fans are fans of other teams and are just as unlikely to be fans of the new team. It will take years before an actual fan base is established.
I'm guessing many hockey fans, and businesses in the GTO area would buy up tickets, and within a few short years they'll grow to love the team (especially if they're better than the Leafs).
Granted - they'll be that 'other team' in Toronto, but getting people there support the new team won't be a problem.
