What is the purpose of the TDG Regulations?

The purpose of the Transportation of Dangerous Goods (TDG) Regulations is to promote public safety when dangerous goods are being handled, offered for transport or transported.

The Regulations are a set of rules that prescribe safety standards and shipping requirements for thousands of different dangerous goods. The Regulations also provide a means of communicating the nature and level of danger associated with chemicals.

The TDG Regulations came into effect on August 15, 2002. These regulations replaced the old regulations that were developed in the early 1980s. This legislation is applicable to all modes of transport (i.e. road, rail, marine and air) in Canada.

What Acts or Regulations are applicable to TDG?

The following set of Acts and Regulations are applicable:

Who needs TDG training?

According to the TDG Regulations, anybody who handles, offers for transport or transports dangerous goods requires TDG training.

The materials in this course are for people involved in road transportation only. If you are involved in transportation by other means – rail, marine, or air – please seek out professional training specific to that means of transportation.

The training involved in transporting Class 1 Explosives, Class 6.2 Infectious Substances, and Class 7 Radioactive Materials is above and beyond the level provided in this training course. Do not take this course when you are offering, handling, or transporting dangerous goods which are in any of these three classes.

Who is responsible for TDG training and TDG education?

The onus is on the employer to ensure that his or her staff is properly trained. The responsibility to ensure workers are trained and the manner in which training is conducted rests with the employer.’s TDG courses are one method of training and, in most cases, additional site-specific training is required.

How long is my TDG certificate valid for?

A TDG certificate is valid for three (3) years.

How often do I need TDG training?

The short answer is 3 years because a TDG training certificate is valid for only 36 months, or three (3) years. However, certificates are also not transferable. This means that if a trainee changes employers, they will need to be re-certified by the new employer and possess a training certificate with the new employer’s name, address etc.

Where do I keep my certificate?

A TDG certificate is required to be kept on the individual when they are working. Most people keep it in their wallets. If a Transport Canada inspector requests to see your TDG certificate while you are working, you are required to show it to them.

What happens if I do not have a valid TDG certificate?

If you do not have a valid TDG certificate, you are in violation of the regulations. Non-compliance of transporting dangerous goods is usually identified through inspections carried out on the highway. Convictions generally produce fines ranging from $3,000 to $7,000 for a first time offense.

If I change employers / jobs, do I have to retrain?

According to the TDG Regulations, a TDG certificate is not transferable between employers. This means that if a trainee changes employers, they will need to be re-certified by the new employer and possess a training certificate with the new employer’s name, address etc.
