^ Well, I cannot blame them at all for being unhappy. The view of 35 The Esplanade from across Yonge Street, almost in line with the axis of the building, is one of my favorites in Toronto. That view will be destroyed when the GO Tower is built, as it will likely block most of the existing building from view (from that angle).
Actually, I am surprised that there is not more of an uproar about this. I imagine that this project is staying pretty much under the radar, and few people know about it, or there would be more opposition.
