How does this affect PARS filing for truck shipments to Canada originating from the USA?

If the consignee on the Highway carrier pro-bill (bill of lading) is a freight forwarder and there are one or more house bills on that truck pro, then the shipment must have all the eHBL and Close Messages filed within the Highway timeframes, one per house bill. This means that the Customs release request will be on the 8000 CCN and not on the Highway carrier PARS.
