Earlier this month, Loblaw Companies Ltd. debuted a new concept that incorporates some of the merchandising practices, labels and foods of its T&T and Arz Fine Foods ethnic banners. The renovated Real Canadian Superstore in Mississauga, Ont., serves the area’s increasingly diverse population, and features a fresh fish and seafood section; a roasted nut and dried fruit counter; a pita bakery; and a wider variety of ingredients used in Middle Eastern and Asian cuisine.
