There was the Montreal show last year - Qwebec Expo.... and I think I remember seeing something about a Toronto event too, although in all fairness it may have just been a party or small gathering.
I have to agree though that Vancouver would be more ideal for us to attend - lots more reasons to go up there... we used to vacation near Toronto when I was a kid so I had my fill up there (Storybook Gardens in London like 6 years in...a...row...), but I know there are a lot of webmasters in that area. Lots of Canadian webmasters and businesses out there though so I think either location would be well-attended.
