Finally! At this point I don't care what goes in there as long as something goes in. (OK a UStore still wouldn't work but Plaza Retail wouldn't do that in any case.)
It'll probably be another Dollerama or Great Canadian Dollar store or something.
I did notice that the water work they're doing on Main Street seems to be feeding into the empty lot next to the Shoppers Plaza; that was sold last year I think and a project has been pending for awhile, though no details have been announced yet that I know of.
