Top 100 Ontario Arts Festivals

Here is another site called Ontario Festivals Visited.
Excellent listings and by season.
All listed are 2008 events but the listings contain a link
to that events web page - which is really helpful in streamlining
your search and the area or location you are looking at.
It contains festivals from Thundeay to Sault Ste Marie for
artists of our area besides the obvious Toronto and Ottawa venues.
