i don't hear about too many conventions happening around ontario, but the one i never miss out on is anime north.
There's actually quite a few more, CN anime is coming up, its coupled with Fan Expo and the like. There is also Northern Anime Festival which is in Oshawa which is really small(300+ people). There is a new con called Dotcon in Toronto. also DTAC (or December Toronto Anime Con) which is 1 day long. There's a couple more that i cant really remember ATM ^^.
but now you cant say you've never heard of cons in Ontario :D
