Okay, I haven't been involved in organizing Drupal Camp TO since 2008, and last year it didn't even happen, but I'm delighted to report that it appears that a new crop of organizers are really, really making it happen this year. So, pencil it in for October 15 - 16, 2010. Once there's a site up, it should be accessible here: http://2010.drupalcamptoronto.org (but meanwhile it's still showing our 2008 camp ...).
Congratulations to the organizers!
[Oct 4, 2010 update: actually, extra congratulations for bringing in an amazing line of keynote speakers, including Dries himself: keynote page. Now - go register before it fills up!]
