Don't know him but I have seen this system specs in a post; I suspect that he won't ship to the great white north because of the risk of damage from shipping (and no way USPS insurance will cover any damage above $50).
There are ways around these walls as I am sure you are aware. If this is one of the 2 systems this guy bought for video work, he must of sold one, but look in the forums for 2 A4000Ts being offered in the same thread with a bit of history about them.
