I have to say that while I'm not a big fan of either Sears or the Eaton Centre, from what I could see this is a huge, well-stocked Sears. I was here yesterday as I needed to be in the area for an appointment and wound up with a very good buy on some clearance curtain panels.
The one drawback I found was that it was not immediately apparent how to get to the fourth floor listed on the store directory, since the main escalators did not seem to go there.
It's always hard to tell if multi-level stores are as big as ones in malls, as the individual floors have smaller footprints. But this store seems pretty large and complete. I also noticed the furniture selection was less "cheesy" than in other Sears stores.
