Along the South end of the site they've already completed the lowest parking level (P3, I think), and they're getting ready to pour the floor of P2. I think the goal is to get the South end of the site back up to grade as quickly as possible so that Simcoe Place can have its loading bays back
Simcoe Place loading docks were moved midblock to facilitate construction. Once this end is done the loading dock can move back and they can start excavating the rest of the block.
