Ugh. Ordering from Jo-Anns in Canada is, well, sadly, impossible at this point. While they'll *happily* put a hold on your credit card, they won't actually ship you anything. You can't even use a canadian credit card to buy online and ship to a post office box - the billing address for the card *has* to be in the US. There was a thread about this awhile ago, with the Snowbirds visiting the US and trying to buy online and have it shipped to their US vacation spots - no dice.
If you're in southern ontario, Len's Mill stores do have the licensed disney fabric, usually with the children's stuff. Also try checking out the walmarts. I think I remember seeing it in the KW area ones, not sure about anywhere else.
