Thanks for the update. The project-specific thread is here:

Open up the corner? Other than the alcove-looking space, the corner appears (in this rendering, at least) to be more encroached upon than ever.
Therefore, I hope this is just a very poorly-placed rendering, because the building appears to jut out onto Granville Street, excessively blocking the view of the heritage facade of the RBC Building to the south. You can even see a large portion of the current parkade still remaining to the east. The rendering also depicts the building encroaching onto the Cordova Street sidewalk. I hope a more realistic rendering will suggest a slimmer, and further set-back, building than the one depicted here, although when city-imposed height limitations force a reduction of two floors, you have to make-up the loss square footage somehow. Of course, the building will not be allowed to encroach on the existing sidewalks.
