I would love to see the parking lots behind the stores between Argyle, Campbell, Edinburgh, Britannia and Cannon fill in. Something like Kiwi condos and 1 Jarvis would be amazing. Plenty of these lots on Kenilworth that could also get developed.
Here's a video of Bob Dylan hanging out in one of those lots back in the 80s.
