I don't think so. I mean if it's not too much more, I don't see why not... but just to be safe I'd say no. see what you can find out about that. Maybe?
Its $2.01 through usps ground international. I've gotten about 350 DVD's and they all cost around the same to send unless they are double disc. Anything under 8oz is cheap to Canada, anything over 8 oz is way too pricey. DVD's are cheap to mail to Canada. :)
