Curry Acura in NY ships to Canada I just ordered a full A-Spec kit for my MR and they honored the group buy prize shipped for $840. In other threads I've read they charge an additional $50 for Canada shipped and fees included.
I suggest u call and ask for side skirt prizes and say you are from tsxclub.com forum and get them shipped to you. Or see if you know someone in the states just across the border and pick them up yourself.
Talk to John he's the parts Manager he'll work with you.
