For a mid-size market, Battaglias has a good selection of gluten free items. GF items are shelved with regular items . The hot table, salad bar and pre-made dinners are very good and fresh but sadly not options for those of us who must eat gluten free. For the record, I eat the pre-cooked bbq chicken (skin removed) and have never had a problem.
Great little market place in the midst of the lorne park area, offers gluten free bakery items in their freezer section, as well as gluten free cereals, crackers and my favorite "maria's" brand pastas which include a chick pea fusili as well as a red and green lentil fusili. They also carry other gluten free items.
