Here's a view of the Vancovuer skyline with a few of the current U/C and proposals included. This was taken from the application materials for 1075 Nelson so several towers are missing, and im pretty sure the impact on the skyline is underrepresented, but it gives you a good idea of where some of the changes to the skyline will be coming.
I thought you were talking about 415 Yonge which is still there, not officially cancelled yet, as far as I know anyway. It was "rejected" by city council. Perhaps the developer will come back with a re-submission?
