Funny, but when I lived on the island of Montreal, I noticed a good number of self-checkout lanes in the newer and bigger grocery stores like IGA and Metro as well as most of the Walmarts. Since fleeing to "moo cow country" I tend to be shopping in the same stores, more or less, but I have yet to see any self-checkout lanes.
I'd have to guess the 'need' for self-checkouts is in part driven by store traffic. The IGA or the Walmart in the nearest town is probably nowhere near as "busy" as one in the burbs of Montreal. I also notice that the shoppers in this neck of the woods seem to be older than in the city (yes, I count myself as 'older' now, too...LOL)
