Transportation of Dangerous Goods – TDG Online

Learn the framework of hazard classification, procedures, and recognizable signage that ensure safety during the transportation of dangerous goods


Every day, drivers are safely transporting dangerous goods across Canada. The idea of drivers doing their job without incident might seem like a simple thing, but an understanding of hazardous materials and their transport is crucial if safety and lives are to be maintained.

When it comes to transporting dangerous goods, worker safety is a top priority. That’s where the Transportation of Dangerous Goods (TDG) Regulations come in to set important standards for the movement of harmful materials and chemicals within Canada. The TDG Regulations provide workers with a framework of hazard classification, procedures, and recognizable signage that ensure the safety of anyone working in proximity to dangerous goods under transport. By standardizing the definition of dangerous goods and setting specific rules for their transport, the TDG Regulations are also able to protect the public and any other individuals involved in transporting dangerous goods.

One way the Regulations help ensure safety is that, in order to legally transport dangerous goods, workers must have on their person a valid TDG training certificate. Certificates must be renewed every three years. This online Transportation of Dangerous Goods course provides that certification to workers while supplying them with the information they need on Canadian standards for the transport of dangerous goods on Canadian roads. It also instructs workers on the requirements for packaging, labels, documentation, and emergency procedures in accordance with international regulation.

After completing this course, an understanding should be gained of:

  • The regulations governing the transportation of dangerous goods in Canada
  • The 9 classifications of dangerous goods
  • The placards, labels, and accompanying TDG symbols required on vehicles and containers
  • Documentation requirements when transporting dangerous goods
  • Requirements surrounding appropriate emergency response in the event of an accidental product release or spill

Upon completion, course participants should also be able to:

  • Classify the various explosives, gases, flammable liquids, oxidizers, radioactive substances and corrosive materials identified by TDG regulation
  • Explain various TDG divisions
  • Identify packing groups and explain packaging details
  • Detail worker and employer responsibilities in the management and transportation of dangerous goods
  • Explain the need for emergency response procedures and reporting


The course is presented with voice-over narration and features photographs, graphics, interactive activities, and chapter questions to enhance the educational experience.


A 48-page .pdf participant manual is available to print and reference while completing the online course. The print materials are also available after the training is completed and can be downloaded from your account home page. Throughout the print materials, charts, placards, and diagrams are included to supplement the information presented in the course. Other supplemental materials included as appendices include TDG regulation exemptions, samples of the TDG Regulations’ schedules, a compatibility group chart for explosives, an emergency contact list for all Canadian provinces and territories, a placards and UN number quick reference chart, a sample dangerous goods shipping document, and more.


The information in this course is presented in seven modules:

  • Module 1: Introduction
  • Module 2: Training
  • Module 3: Classification
  • Module 4: Emergency Response and Reporting
  • Module 5: Safety Marks
  • Module 6: Documentation
  • Module 7: Containers

Topics covered throughout the course include:

TDG Purpose
The course will cover the TDG Regulations goals as they pertain to safe packaging, labels, placards, documentation, hazard identification, accidental releases, emergency procedures, emergency response planning and reporting, and training.

Exemptions to the TDG Regulations attempt to balance public and environmental risk with the practicalities of our transportation needs. This course gives an overview of these exemptions so that workers can ensure they are transporting even these dangerous goods safely.

The foundation of successful TDG management is training, and this responsibility is shared by both the employer and the employee. This course covers the TDG training requirements as they are listed in Part 6 of the TDG Regulations.

Safely transporting dangerous goods starts with correct classification of hazardous materials. This course will teach workers how to understand who is responsible for material classification and explains the differences between TDG and WHMIS legislation.

Classes and Divisions
There are nine classes of dangerous goods under the Canadian TDG legislation, and each class is split into multiple divisions. This course teaches workers how to recognize the different TDG classes and divisions and examines each of these classes and its respective divisions in detail.

Primary and Subsidiary Classes
Many dangerous goods have more than one hazard. In these situations, hazards are divided into primary and subsidiary classes for labelling purposes. This course teaches workers how to label a material with its primary class, subsidiary class, and packing group.

Shipping Name
Contained within the TDG Regulations are schedules that list dangerous goods by shipping name and UN number. Using these schedules as reference, this course instructs workers on how to identify a product by either its shipping name or product identification numbers.

Emergency Action and Reporting
In an ideal world, we would never have an accident or require an emergency response. But the reality is that accidents happen. The best thing we can do is to be prepared. This course covers Emergency Response Action Plans (ERAPs) and the requirements for creating them. It also teaches workers how to take appropriate emergency actions based on an ERAP.

Reporting Requirements
Reporting levels may vary depending on the type of material being transported. This course covers situations when immediate reporting is necessary and the procedures for submitting a report.

Safety Marks
Communication is key when transporting dangerous goods, and, therefore, a key component of the TDG Regulations is labeling your shipment with the correct safety marks. Different substances have different storage requirements, and TDG regulation uses a complex system of labels, sub-class labels, placards, and markings in order to ensure proper handling. This course covers the responsibilities of the various parties involved in transport as they pertain to safety marks and labelling. After completing this course, participants should be able to identify the various safety marks, placards, labels, and signs used under TDG regulation.

Proper documentation helps everyone involved in the transportation of dangerous goods know what they are handling, how to react during an emergency, and how to deal with long-term cleanup after a release or spill. This course equips workers with the knowledge required to fulfill documentation requirements and understand the responsibilities of those involved in the documentation process.

Standard Information
Just like the labels, placards, and safety marks used by the TDG system, material manifests and records also have their own unique protocol. This course provides a comprehensive guide to all of the information TDG Regulations require on shipping documents and waste manifests.

TDG Schedules
The schedules contained within the TDG Regulations supplies those involved in the transportation of dangerous goods with the information required to choose placards and review shipping documentation and packaging. This course breaks down each schedule’s contents so that workers can easily interpret the information they provide.

Many goods are so dangerous that they require special packaging and/or containers with their own set of symbols and classifications. This course covers both small and large container requirements, load security, and capacity requirements.
