Several reasons. One, it's on a side street, not on a major arterial. Two, combined with other development in the area, it will box in Arena Gardens Park.
I don't have a problem with many other development proposed or under construction in the area (Dundas Square Gardens, Ryerson, Pace, Core, 88 Queen). But do have concerns about Grid as unlike previous proposals, it eliminates low income housing, and the Pemberton proposal at Dundas and Church. The Tribute proposal for Dundas and Mutual is another major tower that will knock out more low income housing. This one, at 71 Mutual will further change the neighbourhood.
I think the area needs a breather too as we try to figure out how it best transitions from the current status to a high rise condo district.
