The Secureship system will provide you with all the shipping labels that you need along with a commercial invoice if required (a commercial invoice is a document required for non-document shipments leaving the country and is used for custom purposes).
As a shipper, you are responsible for providing any and all export documents with your shipment. For once, we couldn't paraphrase this any better than our lawyers so check out the section on International Shipping in our terms and conditions (https://secureship.ca/terms.aspx)
