I hate to double post, but I did a little sleuthing (more like comparing) on SSC that I thought I'd post here:
EDIT: the picture from SSC I was using as a reference (photo credit: Jasonzed):Doesn't it beg the question: Why do you need a watermain under a parking lot? I'm sure you might, but the way they've dug it up looks like they'll be adding more standalone retail. Just a guess. More of the same. Any other big-box/small-box shops that might want to open up here? Bed, Bath & Beyond maybe?
Edit: after looking at this site plan, I think this is the new Square One Drive retail, or at least, preparation for it:
Compare that map with the above pictures. You can see on the plan that further retail is planned directly west of the current LCBO/Spence/Boston Pizza/Panera on Square One drive, which is exactly where they're working. The configuration of the first section is slightly different than the original plan (Block C was moved much closer to Square One Dr, Block D was combined with Block B and along City Centre Dr rather than set back from the street as originally planned)
(to compare the original plan with the existing look at Square One's retail leasing PDF: http://www.oxfordproperties.com/leas.../29810_RFP.pdf)
It looks like next up are Blocks E, F, G and H. However, the location of Block E is not enclosed, so it might come later. From the looks of it, it's probably meant for a big box retailer. Block E goes in between where the fence is and the connector road to Rathburn is (before the bus terminal). Blocks F, G and H are all a lot smaller spaces and should be part of the construction now. They should be a lot easier for Oxford to lease out than the Future Shop-sized space that is Block E (I have no idea if it's Future Shop-sized, but it looks it, and FS or BB could definitely set up shop here. See: Scarborough Town Centre's Best Buy).
