RTH the building at the corner of Ottawa and Barton is not indicated on the plans - it does carry the colour scheme for Future Shop, but that's pure speculation. It would be a good spot for a Michael's or Fabricland.
My predictions on the upcoming announcement of category killers for Centre Mall:
- Future Shop/Best Buy (I suspect Future Shop, with Barton/Centennial FS closing and becoming Best Buy at Centennial and QEW)
- Staples/Business Depot
- Toys R Us
- Indigo/Pistachio
