There's a development proposal submitted for the site at the south-west corner of Bloor St. W. and Perth Ave.: "Proposal for site plan approval for the lands at 1439 Bloor W and 80 Perth St for 12 storey mixed use building with retail at grade - 2 stories below grade parking - 120 parking spaces."
Previous discussions about this site were here, but I'm closing that thread and discussions can continue here.
Note: This property possibly falls under the protected "Employment Lands" category for this area. There is some documentation about it here. This could mean that the developers will not be allowed to put in residential units.
The development proposal is documented on the City's website here, although it doesn't really have very much detail.
Here's the text:
