Who we are

Each year more and more dangerous goods are moved across Canada by road, rail, water and air. These shipments range from industrial chemicals to manufactured goods and, while indispensable to our modern way of life, they can pose a threat if not handled safely.

The transportation of such products by air, marine, rail and road is regulated under the federal Transportation of Dangerous Goods Act, 1992. The Transportation of Dangerous Goods Regulations, adopted by all provinces and territories, establishes the safety requirements for the transportation of dangerous goods.

Federal and provincial legislation provide for the regulation of an extensive list of products, substances or organisms classified as dangerous goods. The products fall into one of nine classes:

  • Class 1, Explosives

  • Class 2, Gases

  • Class 3, Flammable Liquids

  • Class 4, Flammable Solids, Substances liable to spontaneous combustion; Substances that on contact with water emit flammable gases (water-reactive substances)

  • Class 5, Oxidizing Substances and Organic Peroxides

  • Class 6, Toxic Substances and Infectious Substances

  • Class 7, Radioactive Materials

  • Class 8, Corrosives

  • Class 9, Miscellaneous Products, Substances or Organisms

A system of diamond-shaped placards and labels is used to identify dangerous goods. Different colours and symbols, such as a flame for flammables or a skull and crossbones for poisons, depict the dangers peculiar to each regulated product.

Transportation of Dangerous Goods (TDG) Directorate

Transport Canada is the focal point for the national program to promote public safety during the transportation of dangerous goods. The department's TDG Directorate serves as the major source of regulatory development, information and guidance on dangerous goods transport for the public, industry and government employees. Through its various components, the Directorate works closely with other federal and provincial agencies to implement the safety program.

It includes information on incident flows and trends, regulatory interpretations, reports on national and international events, regulatory and compliance requirements and activities, risk management and assessment techniques, emergency response and data compilation and reports. It is available upon request and distributed electronically free of charge to more than 23,000 readers.

The regional offices across Canada, ensures that consignors, carriers and consignees are complying with the TDG Regulations through a national inspection, investigation and enforcement program and coordinates the activities of all dangerous goods inspection agencies. The regional offices also provide an information and advisory service to industry and the public.

Other Government Agencies

The TDG Directorate works closely with the Marine, Civil Aviation and Railway Safety Directorates in Transport Canada as well as non-transport departments and agencies such as the Canadian Nuclear Safety Commission, Environment Canada, the Explosives Branch of Natural Resources Canada, and Health Canada. These groups provide specialized advice on their respective regulations. They also participate in compliance inspection and accident response activities within their own area of responsibility.

The TDG Directorate has established working relationships with the highway transport administrations and certain non-transport groups of all provincial and territorial governments. These groups provide advice on regulations pertaining to highway transportation and carry out related compliance and accident response activities.

Industry plays an active role in the regulatory consultation process and in the development of consensus standards.
