Hi Bloomin,
I have to be honest and tell you that I just don't go to many Jazz clubs here in Toronto. I'm sorry I can't be more helpful with your question.
As far as jzz trumpet players in the area, there is Chase Sanborn and Guido Basso. Both are very well thought of around here.
As for the TSO we we are playing very lite stuff at the end of March. If you are interested you can go to
Toronto Symphony Orchestra for more information.
Have a great trip.
Andrew
