I've been noticing for a while now that there is less choice of product in the grocery stores. (Certainly in the many grocery stores I patronize in downtown Toronto.)
Some brands such as Kleenex and Stouffer's Frozen Entrees have disappeared altogether. (Both of which I miss.)
Campbell's soups have far fewer varieties that they used to.
I have written before about the difficulty in finding powder type laundry detergent. The only store I can find now that carries the powdered form of Tide is Canadian Tire.
The latest loss I have noticed is in the variety of jams. There used to be all sorts of interesting options and now there are very few.
