Regarding the decline in Yorkville, anyone watching the last 10 years would acknowledge the impact of Yorkdale pulling away high-end retailers in part because of a shortage of space, a dearth of large high-quality projects along Bloor, the decision of Saks to pull out of the Bloor/Yonge plan in favour of Yonge/Dundas, the large number of high-end hotels opening downtown when previously the Four Seasons was the only 5 star, the move of TIFF. And so forth.
So, yes, and 75 story Foster Tower at Yonge & Bloor with quality retail elements without question helps to reverse this trend. Why argue the obvious?
