Persons who handle, offer for transport, or transport (i.e. handle, ship, carry or receive) dangerous goods must be adequately trained for the work they do. They must either: a) hold a valid Transport of Dangerous Goods (TDG) Certificate of Training that is issued by their employer, or b) be directly supervised by a person who holds a TDG Certificate of Training.

Course Update Notice

This course is being updated to reflect revisions to TDG requirements that were implemented in 2019/2020. The revised version of this course is scheduled for release in early summer of this year. The updated course includes changes in the Emergency Response module and other modules that address emergency responses, revised requirements to safety marks, containers, and exemptions and/or modules that are impacted by the formatting changes that were published in 2020. Note that these 2019/2020 amendments will be included when the revised course is released in early summer of this year.

Please note that it is the employer’s responsibility to stay current with any regulatory changes in TDG and ensure that the TDG education provided will meet the workers’ needs.

View the full list of regulatory changes that have been adopted but are not yet included in this course. This list can assist you in determining if these changes impact your product and type of shipment. Note: the 2019/2020 amendments that are included in CCOHS’s revised course are listed below along with links to the Canada Gazette publications that contain them:"

TDG training consists of two parts:

  • General education on the topics listed in Section 6.2 of Part 6 in the TDG Regulations. This e-course covers these topics.
  • Job-specific training, usually provided by the employer, that is directly related to the tasks being performed, including information specific to the dangerous goods being offered for transport, handled or transported.

TDG Certificate of Training

Because TDG training is job-specific, the employer is responsible for determining the required training, assessing the worker’s knowledge and experience, and issuing the Certificate of Training. Refer to Transport Canada’s bulletin on TDG training requirements for further information.

Although a certificate of completion is provided when this e-course is successfully completed (final exam is passed), it does NOT serve as a valid TDG Certificate of Training. The formal TDG Certificate of Training must be issued by the employer when they determine the employee has a sound knowledge of all the topics (the educational component) and has received workplace specific training that directly relates to their duties with transporting dangerous goods. A sample TDG training certificate is available from Transport Canada’s TDG Bulletin on TDG training.

Course Content

This course provides information about the Transportation of Dangerous Goods Act and Regulations requirements. It includes a detailed description of all aspects of the TDG system for transportation of dangerous goods by road, and is recommended for employers, owners, managers, supervisors, TDG coordinators, and those who have responsibilities for determining the training requirements for employees who will be handling dangerous goods.

The eight modules cover the required content listed in paragraphs (a) to (k) of Section 6.2 of the TDG Act and Regulations. This course includes the SOR/2017-253 TDG regulatory amendment. The course does NOT cover the 6.2(l) ICAO and 6.2(m) IMDG training requirements.

  2. Training, Inspection and Compliance: Describes the responsibilities of employers under the TDG Act and Regulations. Information is provided on training and certification of employees, plus information on inspection and enforcement of the TDG Act and Regulations by Transport Canada.

The information is based on the requirements in the Transportation of Dangerous Goods (TDG) Act and Regulations.

  6. Means of Containment: Describes the various kinds of “means of containment” (such as drums and tanks) for dangerous goods under the TDG Act and Regulations. Includes information on the UN Packaging system and other standards for means of containment, certification safety marks, and other requirements such as handling and storage of the means of containment.

  7. Emergency Response: Describes the various types of dangerous occurrences and the requirements for reporting and responding to leaks and spills under the TDG Act and Regulations. Includes information on the use of the Emergency Response Guidebook, and the Emergency Response Assistance Plans (ERAPs).

  8. Special Cases for Road Transport: Describes exemptions or partial exemptions from the requirements in the TDG Act and Regulations. Explains when special cases can be used.

Examples and quizzes reinforce learning and each module includes a self-assessment to test understanding of the material.
