Loblaws owns a huge variety of grocery stores in Canada and they also have a bank (President's Choice Financial) as well as large real estate holdings. There are a fair amount of places in Canada that only have a Loblaws store in the vicinity. As a Canadian, painting them as some sort of boutique luxury store is very strange to me as they have huge grocery stores and are generally considered to be on the cheaper side.
You can see by this graph here: https://www.statista.com/statistics/481019/leading-grocery-r... that Loblaws is probably the biggest grocery retailer in Canada.
