I have Canadian Goods returning which has not been advanced in value or changed in any way, what proof do I need to provide Customs that it was originally from Canada?

Canada Customs will accept various documents as proof, but they must be able to match the product on the export documents with the product being imported. Examples of proof of export would be a bill of lading, foreign customs documents, and accounting documents. It is important to know that if proof is not supplied to Canada Customs if reviewed duty and tax could apply to your goods.
