Sure, but why?
That is to say, supertalls drive up construction costs per ft2, the added density also means the need to upgrade area infrastructure, from sewer to water, to schools.
Growth isn't free.
I'd like to see a thoughtful plan for the entire area come out in front of further development, and I'd like to see the Sheppard subway extension actually open first......
I recently worked* in this area for two years, and it has a lot of potential. If enough of the old stock office buildings are retained, whether as office or as residential conversions, and the parking lots and low rise buildings infilled, it will have a nice diversity of architectural eras and styles, something missing from other suburban nodes like VMC.
The basics of a decent street-grid are in place, and the separation from any SFH neighbourhoods will make it easier to go big. I also appreciate that it is square in shape, as much suburban redevelopment follows arterials and therefore is linear - here we can build a true neighbourhood on two cartesian axes.
In theory, this is well-located as well, but there are horrible local traffic patterns that cause significant jams in the morning and evening rush. In terms of transit, it feels near to Don Mills Station, but in reality much of the area is a rather long hike, and an unpleasant desolate one crossing Highway 404.
Really, development should be constrained until the Sheppard subway is extended, but once it has been, this really will be a great location, being well connected to the regional road network, but finally accessible by transit.
But it really needs to be planned properly. I could not agree more with
@Northern Light about the need to seize the opportunity for one or two large parks rather than a proliferation of small ones.
(*it was 2020 to 2022, so a lot of my time was work-from-home, but I was in the area with reasonable frequency)
