I found two that will be on in Sept. 2009
They have one for a day each year in Waterloo, ON It's Sept. 19 this year and it's quite well done http://www.royalmedievalfaire.org/
And there will be one for two days in Milton, ON Sept. 26, 27 www.countryrenfest.com OR www.fairesintime.com
Hah- the Waterloo faire is on international talk like a pirate day ~ :D
But anyway. I'm hoping to attend both of those this year, as long as I can find people to come with me. At the very least I will be going to the Milton faire, but that Waterloo one sounds great too.
