What Federal Acts and Regulations govern TDG?

Transport Canada – Transportation of Dangerous Goods Regulations

What purpose do TDG regulations serve?

TDG regulations exist to improve public safety when dangerous goods are being handled, offered for transport or transported. They are a set of rules that set safety standards and shipping requirements for hazardous goods. The Regulations also provide a means of communicating the nature and level of danger associated with chemicals by means of placards and hazard symbols.

What is meant by TDG Clear Language Regulations?

These came into effect on August 15, 2002 and replaced those developed in the early 1980s, which were more complicated. They apply to transport of these hazardous goods by road, rail, water and air in Canada.

What is TDG Amendment 6?

TDG Amendment 6 was published by Transport Canada on February 20, 2006 and came into effect on February 20, 2008. Changes were made to the classification of some infectious substances, documentation, Dangerous Good Safety Marks, Means of Containment, ERAPS, Accidental Release reporting requirements, placarding rules and several other changes.

Who needs Transportation of Dangerous Goods (TDG) training?

Anyone involved in handling, offering for transport or transporting dangerous goods must be formally trained in TDG.  This includes shippers, receivers, including those who load and offload dangerous materials.

Do I have to have my training certificate with me?

When you are working you must be able to show it to an inspector or police officer if asked. You should keep it in your wallet.

How often should employees receive TDG training?

Trained employees must carry with them the certificate supplied by the training company and this must expire in no more than3 years. These training certificates are specific to your employer and become invalid should the employee change companies.

How does TDG relate to WHMIS?

TDG Regulation deals with controlling the immediate hazards of exposure to hazardous materials in the event of a spill or leak during transportation. WHMIS is about controlled products for industrial use and deals with the effects to workers of hazardous materials. Whenever there are WHMIS controlled products present in the workplace then whoever transports those products in, out or disposes of them must be trained in TDG.

What is an ERAP?

Emergency Response Assistance Plan. This plan must be prepared and then filed and approved by Transport Canada when certain hazardous goods are transported. The OSG TDG training course provides details of ERAP’s, how and when to prepare them and how to notify the authorities.

How will the GHS (Globally Harmonized System) affect TDG in Canada?

Canadian TDG Regulations are already based on the United Nations Recommendations on the Transport of Dangerous Goods Model Regulations. Only acute health and physical hazards are addressed by GHS and GHS symbols used for them are the same as those used in the TDG. More detailed information is available at: Information about the schedule for implementation can be found at:

What training records must be retained for TDG Training?

Employers are required to retain written records of employee education to ensure proof of compliance with the Regulations. OSG will also maintain records of your attendance should the authorities require further verification.
