Yes, though the bizarre prohibition on restaurants in those buildings is a huge problem, and rather odd given the amount of Green P parking behind the buildings. Removing that prohibition would at least start filling up some of those units.
Ironically, walking down Queen, the piece that feels the loneliest is the piece of park between Northern Dancer and Kingston. I'm all for parks, but would the streetscape have worked better with a small strip of 2 story stores there instead of the park (which would still be huge with that cut out. Though perhaps just better streetscaping without the ultra-narrow sidewalks and lack of trees would do something ... how did such a travesty of a park ever get approved?
Not really sure what the point of the city objecting to this is. Looks pretty benign for the intersection of 2 major arteries with excellent transit. Probably says more about the new guidelines for development than anything else.
This park, as a whole, particularly in the south is quite appealing, a wonderful fountain, a wetland (stormwater pond), forest, a concert venue etc.
The north-easterly portion you bemoan was actually meant to be for a new school for the Beach area. At the time of planning every school in the beach was portable laden and the need for a new school seemed quite pressing.
The combination of changing demographics, but also what amalgamation has done to how new spaces are funded are the provincial formula means a new school is now quite unlikely, at least in the near term.

You'll find it under 'vacant land'
I'm uncertain, but I don't believe it has been designated for disposal.
The shortage of trees is due to the the future footprint of a school and a playing field.
