Well, if we're going to read into that rendering, the reflection on the windows suggests that this hotel faces Toronto's skyline, circa 1967 with TD Centre on the right (that is, the left) and Commerce Court and the old Bank of Nova Scotia beside it. Judging by the position of these buildings, and taking the mirror image into account, I would surmise that the Toronto Airport Hyatt is actually a lost design for the Toronto Island Airport from 40 years ago, and that this hotel was built on land appropriate from demolished island cottages.
