Just me, the concert hall queen, lurking ...
Massey Hall is on the protected list of course. Friends and I were talking about her over drinks last Thursday night. I opined that until someone or some organization can figure out a use, she should be left alone, as is.
Toronto's getting big, and has lots of new stuff. Sometimes an old relic in the middle of everything serves a purpose of its own.
Adding to US' comments, no, we can't absorb another concert hall into our stream right now, but when RTH was closed for renovations, I was thrilled to go back to Massey; those are acoustics! Roy Thomson Hall, acoustically, is like a lover who promises to take me there, but just never does.
