a) Parkdale was re-developed decades ago. Lots of towers. It has one of the highest densities in the city and doesn't 'need' more.
c) Stable is good. Parkdale has its share of everything. It does not need to be crammed further.
d) It's still within a mile. Again, we don't need to push up the density in Parkdale. Look to the west side of the Humber (not Humber Bay, but along The Queensway and north of there) to see where density needs to increase. Look north of Bloor to Eglinton, and on and on.
c) 'Need' isn't how these things work. Nor is the idea that you can just 'turn off' development in a certain geographic area (though the OP does attempt this in 'Neighbourhoods').
b) That's not what you argued originally.
d) see "c)"
