Anything that is imported from the US that is made overseas, specifically China is subject to 6.5% duty plus some additional small charges with the shipping company with respect to brokerage fees(depending on the value of the item) and of course shipping costs which will be reflected in US dollars as well. Of course in addition, because prices are posted in US dollars, you have got the exchange rate to deal with plus the usual sales taxes upon delivery. Some shipping companies will want you to pay these additional charges immediately upon delivery, others might bill you for these. Essentially, the companies that I have dealt with that do US to Canada deliveries are either UPS or FedEx. You should be able to find out most of these charges from the shipper and carrier ahead of time so you will have a pretty good idea as to what the total cost is going to be.

Certainly these additional charges can add up, but when you see that there is not a lot of choice out there in multi-channel power amps and those that exist are usually VERY expensive, importing an Emotiva or an Outlaw with their wide choice of products, even at the current exchange rates along with the additional charges, you are still way ahead of the game.
