it depends on what you mean by compete. If you mean successfully attracting transnationals to locate their offices there for a twenty years or less, then I would say perhaps, but the remoteness of the location and the debilitating traffic snarls of markham might even make that an impossibility.
in any other sense, i would say definitely no. NYCC and MCC are not at all like DM, they are both areas that are seeing intensification on an already existing landscape, and their projects are all done by different people for different reasons at different times. the builders here are using the same paternalistic b-s way of planning that they have the whole time, which is to control every aspect of a large area, not a single property. this is much different than how NYCC was intensified over the course of about 150 years! way before there was even a four story house near yonge and shep, there was definitely a place to get a glass of water and go to the bathroom. because those are basic human needs.
DM is not strategically placed, it has literally nothing going on, and even if it does one day, it will work much like an amusement park or a mall, as it is not a natural environment made by a community of people, but rather by the same shitty people that made the shitty suburbs that surround DM for miles all around.
and (sorry, total rant), no matter how much people gas on about viva, the remote location will ensure that DM is entirely autocentric. it may have pedestrian only streets, but probably in the same way Wonderland does.
