Edmonds is the most spaced out of the town centres in Burnaby.
There's a bit of a battle between commercial focussed on Kingsway & Edmonds, and the unbuilt potential for commercial at the SkyTrain Station.
I think a commercial core at Edmonds Station will depend on development of the empty BC Hydro lot and space across the street.
i.e. commercial space would be viable if it is "on the walk" between the station and Southgate and would draw from the north as well.
I doubt a commercial core away from the station in Southgate itself would be successful.
