I was trying to find some old pics of the Victoria Bay redevelopment from about 14 or so years ago, but not much out there. Similar to what will happen with the larger Winnipeg store, it was stripped to the concrete floors and pillars with the heritage exterior retained and restored in full, plus earthquake proofing and the hole cut in the middle.
A recent real estate video will give you a good idea of how they create a core, but I believe the Winnipeg one will be a bit different plus the atrium in the middle will be open to the public. In Victoria it’s just for the residents and the Public Market and other retail is below this grade.
