Responsibility of the shipper
It is the responsibility of the shipper to identify, classify, package, mark, label and fill out the proper documents to be included with the dangerous goods that will be transported. Concerning the documentation, the shipper can refer to the documentation section in the Guide on the Transport of Dangerous Goods for more information. https://www.transports.gouv.qc.ca/fr/securite-signalisation/securite/Documents/GuideTMD.pdf
The shipper must have received a dangerous goods training (packaging and expedition of TDG) as well as always have in his possession the valid training certificate (36 months). If a person does not possess this training, he can perform his duties under the direct supervision of a person with TDG training. Furthermore, the shipper must, if necessary, provide the identification placards for dangerous goods that are suitable for what will be transported.
