Note how the blue lantern of RBC Centre is reflecting off Royal Plaza to the lower right. Also note that Cityplace Apex has now reactivated some its rooftop lighing elements
There's one lot at Esplanade and Sherbourne/Princess. Other than that its knock down which I can't see happening anytime soon. The neighbourhood as it is works really well.
Market Wharf, 18 York, and, eventually, Five Corners will change that view somewhat. Also, there are plenty of empty lots still along Front between Sherbourne and Parliament, at Church and The Esplanade, Church and Colborne, etc.
