Here's an interesting vintage pic of the Dominion store that used to exist at Confusion Corner (it's the same building that houses Dollarama today).

I wonder why a supermarket ceased to exist on that site... it seems like a winner of a location given the proximity to neighbourhoods that don't strike me as having a ton of options when it comes to groceries (Osborne Village, Riverview, Fort Rouge).
