I think this is a somewhat outdated view (shopping malls needed anchors because anchors drove traffic - in many instances anchors also developed those malls). That has changed significantly. Oakridge, Royalmount don't have traditional anchors.
I suspect we'll CF continue to focus on being the west-end destination for higher-end brands that you can't find at Square One and use that to drive traffic from Etobicoke all the way to Hamilton. Pottery Barn, Williams Sonoma, a flagship Harry Rosen, etc... (I've mentioned this in other threads, but i also wouldn't be shocked if Holt's comes back to Sherway).
