I have no idea, guess I'd have to inquire. However, if you would order from tirerack shipping to canada is about $120 more than the US from my estimate.

Update: Looked into it. Yes shipping is quite a bit more and for a set of 4 via UPS they are approaching $200 for shipping. No idea about VAT stuff though. I don't know how favorable the exchange rate is for you. Maybe you could ship them to someone in the states and pick them up yourself? We'd love to have you help us to hit 15!
