You don't need an office in Canada to ship here. If that were the case everyone on Ebay would need an office here. Import laws apply to Canada not the USA, you are exporting not importing, as long as duty and tax is paid, done. Called Free Trade Agreement. ******** in Phoenix doesn't have a problem shipping to Canada, I am sure they don't have an office up here anywhere. All taxes, duties are billed to the consignee, it has nothing to do with who's sending it. It is simply a matter of a bigger stamp.
