The City blew its chances on air rights over the O-Train between Gladstone and Young nearly 10 years ago. There was City or other government-owned or industrial land on both sides.
They blew it on air rights at Walkley Road, by refusing to allow a developer to get a rezoning from the track to the corner of Bank and Walkley. They insisted that the latter had to remain zoned for single-storey auto dealerships.
They blew it on air rights at Bayview by not buying the NCC-owned land in the southeast quadrant at City Centre.
They have recently blown it at Carling O-Train station by refusing to allow the developer of the adjacent property to do a sensible development of the air rights. They will lose also at the OMB.
They blew it at Baseline by not forcing Algonquin/aka the Province to pay for the entire cost of the transit station in return for the air rights.
They have no idea what they are doing.
