Eaton Center, China town and play guess what hanging in the window, Ontario place, parliament area, science center, if it was colder you could go skate at the city Hall, art gallery, fort york, Cn tower - just for the view and as duty say, eat some food. Casa loma, ROM, check to see if it have any games going on at the ACC. Take a break and people watch outside the eaton center with ah hot dog (make sure to pile on the condiments so your belly will full when you done - doh mind the stares from the odda patrons).
Try to take een one of the shows.. the ladies love "dirty dancing" plus there are many others presently playing.
old to young, TO have real things to do and enjoy.
