I think local people in general hates walmart, that's why none in Vancouver...They were talking about having one on Marine Dr and close to Main for long time but got banned.
But for consumer...I don't see why not...I always welcome lower price and competition.
Won't be too bad for superstore because walmart sells less grocery...
I guess it's a bit difference here. I usually go to Chinese supermarket for grocery. Only will go to local supermarket for milk/butter/cheese etc.
So I don't find Walmart that bad for those products.
