Interesting. This may have been mentioned already, but due to the fact that the existing Bay Adelaide loading ramp off Richmond bisects the ground floor of the north tower, the east and west halves are fairly separate. According to the plans, the east half will serve as the building lobby (with two elevator banks), while the west portion is marked as retail. A bit of animation for the west end of this stretch of Temperance.
I'm wondering if that retail would be a new food court, because it doesn't look like there's any space left for one downstairs.
