Hi,

My business is selling products to China from Canada, we use a third party courier to do the shipping, we get a waybill for each shipment, and it can be tracked on the courier's website, the CRA asked to provide sufficient proof in order to prove that my supplies are zero rated supplies or they will considering me to be making taxable supplies at the GST/HST rate of 13% for all my sales, which is so wrong. We don't even sell locally to Canadian market at all.

As we don't do the export shipping ourselves, we only get the waybills from our courier, I am wondering if this is sufficient to be the export documentation? 

Thank you very much.
