Well, I might be a little qualified about the Eaton Centre--after all, when all is said and done, Zeidler was hired to perform an urbanistically-correct quick-fix on a predestined blockbuster. Worked with flying colours; but, still.
Came about at just the right time, too. A few years later, there might have been a more vocal outcry over the loss of the old Eaton's store and the whole Yonge blockfronts north of that; not to mention the old Eaton's warehouse (which these days, might be coveted for some kind of office/institutional/condo conversion; imagine if *it* contained the Rye High Biz School...)
