Jason Kay is the editor of the Hockey News, and is not the kind of guy to tweet something like this without knowing for sure:
Site plan application for second NHL-sized arena in Toronto area being submitted this Wednesday. Could lead to building permits by the fall.

There’s likely enough disgruntled Leafs fans that if the city ever did get a second team, they’d be more than willing to jump ship.
Who knows what the intentions are here, but with the population and interest in hockey in that city, I can’t see an NHL-ready building sitting there and being used solely for Bieber concerts.
