The more I think about this debate the less it adds up. Something else is at play, Tall Poppy syndrome. There's a constituency aggravated that some accomplished people have decided to do something audacious. This seems like a perfect opportunity to teach them a lesson they'll never forgot, a bit of hog-town humble pie. Some of these objectors see themselves as smarter that M/G if less appreciated.
City planners are miffed. M/G can't have it all! They must build shorter, or they must incorporate some crappy warehouses. We must have some fingerprints on this! We can't serve up a city block on a silver platter after all...
If I were M/G I'd be thinking there are a lot of people eager to see me fail. Maybe I should just sell this block to Allied and use proceeds to buy an entertainment company. Watch critics hide their chagrin.
Fortunately for us M/G are city builders rather than keyboard critics.
Just when Toronto is on the verge, in typical Canadian style we get cold feet.
You think too much.
First of all, the secondary plan for King-Spadina presently does not allow for 80 floor buildings. That issue was no where near being resolved when the applicant decided to move for an OMB hearing. That action checks the applicant out of working with the community and the cit (so much for "city building" effort). If you ever spoke with with Mirvish, he will wax on about these buildings and what they will do for the city, but you don't get a strong impression that he has much interest in the local community (meaning the people who live there included). Some of us get a little tired at being treated like road cones by developers.
Second, as the buildings are out of proportion to the existing building guidelines for the area, so it should not be assumed that planners are instantly ready to toss everything aside to satisfy the applicants desires for a type of trophy or memorial building to Frank Gehry. A number of other developers have worked with city planning in developing a planning regime that has added significant density to the area. The M-G proposal would blow that effort away. There is also the issue of what will come next should the OMB allow these buildings to go forward. Such a decision pretty much puts the developer in full control as they do not have to answer to anyone. You don't leave a lone developer in charge of building a city.
Third, regardless of how much you hate the existing warehouse buildings because they stand in the way of the tall buildings you want, there is still a legitimate heritage argument being made for them. Merely sneering at that argument does not render it as discredited.
Fourth, if you assume that these three structures mean that style has finally arrived in Toronto, then I suggest you don't know your city very well. Making such a statement on the basis of renderings is a pretty sorry route for arriving at this judgement.
As for issues about density, there were 1,700 residents in the King-Spadina area in 2001. There are 8,000 living there today. There are 16,000 residential units built, under construction or under review in that area. The potential population would be around 24,000 if these are all built. Add to that, there are more on the horizon. That's hardly a failure for achieving "density."
Add to that, unlike a rapidly developing neighbourhood like City Place, King-Spadina has a significant employment component. There were 24,000 jobs located in that area in 2001. Today, that number is over 35,000. The potential is for over 50,000. There is significant commercial development effort under way in the area as well.
To be blunt, questioning one extreme development (M-G) is hardly diminishing the ever increasing population and employment density in King-Spadina. Toronto needs a lot of things, but when to comes to development issues, it needs reasonable and sensitive judgement.
