Shipments received with Unknown Consignor status will not be loaded onto a passenger aircraft unless additional security measures have been taken.
According to the Air Cargo Security Program, Registered Shippers in Canada with Air Cargo Security files will be automatically shifted to Account Consignor status. Cargo operated by an Account Consignor will be screened to make it secure before it is loaded onto the aircraft.
As of 17th of October 2016, the Registered Shipper category will no longer exist in Canada. It is advised that any companies currently being under the Registered Shipper category, submit an application as soon as possible in order to avoiding screening delays.
