Who gets the DO NOT LOAD (DNL) notice on a multi-level consolidation? Master loader and lower level forwarder?

CBSA has advised that in the DNL notice will be sent to the primary notify party (party that submitted the document against which the DNL was posted) and any related automated notify parties or secondary notify parties. In other words, the party that submitted the related MBL or HBL will get the DNL, as well as any other parties listed on the document; e.g. carrier listed on NVO HBL or NVO listed on carrier's MBL.
