Andrew: Thanks for the aerial view. Not to be nitpicky but the area which you have shown in red is larger than the actual condo site. The site does not include the gas bar, on the corner of Yonge and Church, nor a big chunk of the parking area north and east of the gas bar. It does not have any Yonge St. frontage.
As for number of buildings, I am not positive but would guess at this point that there will be only one building. An application had been submitted by Canadian Tire to the City back in 2002 for two buildings of 25 storeys each, but this had not been approved. Some may recall that there was controversy over it, sparked by a neighbouring landowner to the east who had a concern about shadows. The site was subsequently sold.
