Have not ever dropped, anywhere in North America where these are permitted.
The height limits are as-of-right, and we are seeing lots of projects move forward, not just one or two.
They are not 'case by case'. Where we have seen issues, its because of builders seeking other variances that are typically going to the C of A and losing there. (many don't, but many do)
With great respect Toronto is among the most permissive jurisdictions going at this point.
I have great relationships w/developers who post or lurk on UT...........and have an open door if they want a policy changed.
I'm not in City Planning, but talk to planners regularly and councillors and for the most part, if anyone can make a good case, I have helped make the process easier for them.
I really don't accept that Toronto, at this point, overall, is unduly restricting on planning compared to its peers, because frankly, it isn't true.
There are always opportunities to tweak some things......Not that long ago, I helped address problems with bicycle parking standards that were unduly onerous. (to be clear, many others played equal or larger roles)
That said....zoning is not a key to affordability for reasons I've outlined.........its a much more complex issue than that. I advocate on those other issues as well.
I just object to this perpetual canard that Toronto is exceptionally restrictive or slow with approvals when it is neither, overall.
I support reducing amenity requirements, which I think will be beneficial, but only at the margins. Ultimately the mismatch between incomes and housing prices is far more of an income issue than a housing one.
Though if you wanted to sink rents and ownership prices tomorrow........ I'll give you a way to cut them 10% clear across the board. Ban short-term rentals......... No more Air BnB ......that'll do it.
