darn.
I don't have the enhanced license or passport.
Nothing really to see over there in canada.... 
Is this every year?
United States license is valid in Canada. No need for an international drivers permit.
You need proper paperwork to get across the border. Enhanced licence or Passport are what you will need for that.
Source: I live in Buffalo and travel to Canada on occasion.
Wow. Guess my source from United States government website was wrong. Can never rely on good old USA for correct info. I should have known. My state DMV website is wrong half the time. Thanks for he correction. That would have sucked.

The license will let you legally drive there, it just won't let you in to the country or back into the US

I also live in Buffalo so it is a short hop across the border to the show.
What do you do? Stare at all the funny books sealed away in plastic tombs?
Yup, sometimes I rescue a few of them and bring them back across the border to read. I collect lightly to read not for the value. It's also fun to watch all the costumed cosplayers walking around, meet and chat with the (often faded) stars that attend. This year an arcade is just a huge bonus.

Last year I got to meet Kevin Eastman and that was truly fun.
