Yes, by a long shot - current tallest is Metrotower II at 111 meters. However, I believe Bosa has proposed a tower for Kingsway and Willingdon that may go even taller. Exciting times.
Edit: Just had another look at the Empress Tower thread
, and it's only proposed at 45 storeys - so maybe Metroplace, if built as proposed, will be the tallest for a while.
