I feel that Hayden exit isn't long for this world. The 33 Bloor building is (from what I've heard) is doing poorly; all retail is currently vacant and has been for a while now. Not to mention that Hayden entrance is routinely absolutely filthy. Completely anecdotal, but I've seen that entrance (and the associated elevator) used as a washroom on several occasions. With a much nicer entrance off Yonge, with interesting retail to draw attention and feet, I think the traffic from the Hayden side is gonna diminish greatly. The appeal to the potential retailers (if they ever get someone to even look at a lease) is gone. The only advantage left is the accessibility elevator to the TTC. And they'd be better off disabling that middle floor and allowing access only from Bloor-ground.
