Oddly, I've never gone up in the tower -- we're always doing other stuff when we're in Toronto, and we go to TO less often than we should anyway. I'd love to go up there, though; as a kid, I remember when we'd always make the trek to the top of the Space Needle when we went to Seattle.
Anyway, more photos of the construction phase here. I guess I was wrong in that they didn't build the thing complete, lay it down on its side, and then pull it upright.
(No, I didn't think that.)
