The white glow atop the core in the above photos is the white floodlights above the edge walk on the CN tower. It was foggy as well so can't see the CN tower or only a faint outline of it.
This one's huge floorplate and roundedness reminds me of 1 Manhattan West going up in Hudson Yards. I'm confident this will be a stunner and am waiting impatiently for the first signs of glass.
