Flower shows and autumn leaf viewing are for many Toronto residents as much a tradition as the Ukrainian parade. For the Autumn Chrysanthemum show free at Allan Gardens Conservatory, see below. This is easily accessible by public transit near the corner of Carlton and Jarvis.
For an up-to-date report on fall colours as they progress from north to south in Ontario, see: http://www.ontariotravel.net/publications/fallcolourreport.pdf . You will need access by car.
For good places to see our famous red autumn leaves in town: http://gocanada.about.com/od/torontoattractions/tp/toronto-fall-colours.htm. Most of these available by public transportation.
Please let us know your favourite leaf-viewing spots. Ruth.
