Don't need to see the cladding to know it's curtainwall. Look at the concrete, they've left pockets along the slab edge to receive the anchors that will be holding the curtainwall. Those pockets wouldn't be there if this was going to be window wall.
Working in the area this afternoon, walked by to snap some shots of my own. Here are some closeups to add to AlbertC's pics, including some spandrel sections on the laneway side I noticed.
The glass is very reflective, and reminds me of that being used on Yorkville Plaza right now.
