I think the lower floors of Telus were significantly more complex and required much more work to build, tho that would only account for some of the lag
From that perspective I don't think much of the CN Tower will be visible at all. Maybe possibly from the upper observation deck and up, but not much more than that
i know it's great to have a 43 storey building under construction. but really.
it makes simcoe place look hot and sexy.
it looks just like the render...a big tubby glass box.
