Very true, their views are partly obstructed but they'll still be able to see around The One. And at least it will be a good looking building that they're looking at.
The One's not even built but I already know I'm going to miss that view of One Bloor from Bloor Street west ^. This is a beautiful building, and the slenderness of the building on it's east/west sides is perfect.
Steve, I will miss the view of One Bloor East as well, in fact I think I will lose my view of it almost completely from my condo once One Bloor West is built.
With a bit of luck The One will be set back enough from the Bloor street sidewalk to allow One Bloor East's vertical glass reveal to be seen along Bloor. It makes a nice view terminus when walking eastward.
