For items mfg'd in North America there shouldn't be any duty charged between Canada and the United States. For Canadians importing goods from the states we pay Goods & Services Tax and if applicable provincial tax. On top of these Taxes, shipping companies will normally charge a brokerage fee. I have found that Fed Ex is the most reasonable with these fees. They normally charge me about $7.00 CDN. I have had other companies such as UPS and Priority Post charge quite a bit more. Sometimes as high as $50.00. Not bad on the whole.
