I live about 5 minutes NE of here. I'm all for yellowbelt intensification here on Campbell, although it's a shame that Marlin Spring are the ones doing the assembly.
The retail plaza lining Symington with the Beer Store is also prime for redevelopment. The plot of land to the east features a large amount of employment space. It's not really an aesthetically appealing group of buildings, but it serves reasonable contributions to the area.
The Beer Store / Caldense plaza was up for sale off market a year or two ago. It excludes the BMO on the corner but includes the parking lot north of 336 Campbell, and part of the frontage on Dupont IIRC.
Nothing worth saving.
Saving the trees would neuter the site. You can't shore around trees that large (or of any middling size, really).
Interesting. I pass through here almost daily and have often wondered why that plaza with the beer store still hasn't seen any development, or the Piri Piri building, or the brownfield on the corner. Seems there are ample opportunities for developers in the immediate area...
