Putting down my guesses: grocery, hotel, retail, office
Lower level: food hall / grocery (Loblaw or Whole Foods tier). Floor lowered 9ft to provide a seamless connection from Bay Adelaide Centre PATH through the food hall with vaulted ceilings and level with the Queen Station Line 1 platform and Line 3's new concourse with an escalator up into the Eaton Centre and another down to Line 3's platform.
Main level:
- Restaurants on 3 corners: Leña on Richmond and Yonge proved the concept. Restaurants on the other 2 corners on Bay/Queen and Bay/Richmond.
- Yonge/Queen corner: Hotel entrance and lobby where Saks was. Access to the upper levels. 2-3 floors of rooms, about 100-150 rooms. There's demand in this area, the Sheraton is regularly sold out in the Summer and during major events.
- Queen Street frontage: 2 stores, one for each entrance on Queen and each escalator bank. These may have access to a second floor.
2nd floor: 2 stores, on either side of the bridge, possibly a continuation of the stores below at street level.
3rd to 4/5th: Hotel rooms
6th and 7th: loft office spaces connected to Simpson Tower.
8th floor: Arcadian Court event space
Some of this is reliant on the subway station being complete. The lower level requires a substantial amount of work to integrate into the new subway station and street level on Queen Street is unattractive to tenants given the construction activity and narrow passageways facing hoardings. I could see Leña returning soon and a restaurant being outfitted at Richmond/Bay. I could also see temporary tenants on the 2nd floor across from the bridge for a couple of years while they reconfigure the main floor for separate tenants.
