Transportation of Dangreous Goods Canada Dangerous goods are commodities that, when transported, pose some form of danger to people, animals, the environment, or the carrier. Dangerous goods can be either acceptable or unacceptable for shipping. The Transportation of Dangerous Goods (TDG) Program develops safety standards and regulations, provides risk-based oversight and gives expert advice on dangerous goods to promote public safety in the transportation of dangerous goods by all modes of transport regulated by Transport Canada. There are nine classifications of dangerous goods that identify the type of danger each possesses. You are responsible for correctly identifying, classifying, packaging, marking, labelling and completing documentation for dangerous goods according to national and international governmental regulations. The government requires you to have job-specific training before offering a dangerous goods shipment
