When I shot it on Friday, I had the same thought it been top off. Looking at the close up shot, looks like another floor to go or doing the mechanical roof is next. May know better later today, as I will be closer to it than Friday
This building always catches me because I don't expect to see height there and it's so generic so I'm always like "what is that building??" Pretty cool to see a local height peak beginning at University/Dundas though.
