This whole area of town (CBD West end) needs a grocery store. Part of the fun of living DT is being able to walk to get your groceries and it's a good hike for the thousands that live in this area around Slater, Bronson, and now Lebreton. I still think they should build a tower on part of the old technical high school site and have a large grocery store in the podium. As far as retail goes, it's the only type of retail that everyone (I think) needs and uses on a regular basis. Look at some of the best central neighbourhoods in TO and the streets are always bustling with people walking home with their groceries in hand, makes life a lot simpler (no need for car, cab, bus...). Here's a nice example of a ground-level supermarket in a condo in Manhattan:
OK, I'm done ranting.
