Fan Expo in Toronto is the largest genre convention in Canada and the third largest in North America, so it was great to be there as an author guest and panelist. I was located in the Guests area, close to the Back to the Future, Delorian time-machine, with 10 other authors and ~10 voice-actor guests. There were about 25 author panelists and 35+ authors in the science fiction / horror genres at the convention, plus some comic, animae and gaming writers, so it was a great place to meet authors.
The costumes and cos play were excellent. There was a lot to see; great guests, Q&A sessions, exhibits, lots to buy and lots of people. Fan Expo is held over the last weekend in August from Thursday to Sunday.
