Each parcel to be shipped by Canada Post needs to have a shipping label affixed to it. X-Cart’s Canada Post add-on allows you to obtain shipping labels for your Canada Post parcels.
Once you have chosen to create a new shipment, the add-on contacts Canada Post and obtains a shipping label. You can access this label using a link in the "Shipment info" section of the shipment details. The label needs to be saved on your system as a PDF file, printed out, and affixed to the parcel.
