Apparently, the second floor will be occupied by a grocery store...Whole Foods is supposed to locate in Hullmark across the street, replacing a Dominion, so my guess would be a Dominion or a Sobey's (or some urban variant).
As long as Bazis builds this complex with attention to detail and quality of the [100% glass] finishes in mind, it should be quite something. I hope the tones of green glass they're planning work out in real life and not just in renderings. The podium is not typical for North York and almost everything rides on what the various overhangs and undulating plate glass walls are like at street level.
I'm not sure how the subway connection will work in terms of being integrated with commercial/residential lobbies...the TTC is being difficult, as usual, and demanding non-integrated subway access because of safety.
