You'd have to contact HSU about that, AFAIK when you bring audio equip't into Canada from the US, you just pay GST and PST as if you had purchased locally. I actually went to Canada Customs in person about 6 weeks ago and enquired about bringing audio equip't across the border....keep in mind I am referring to bringing said items across the border myself, not through a broker or ordering online for shipment. Contact HSU, see what they say, I'm sure they get a lot of enquiries from Canada.

Half of communication is listening. You can't listen with your mouth.
