Harbor with ship full of cargo

The Transportation of Dangerous Goods Act (TDG) is an essential part of the transportation industry. Through airports, trains, highways and harbors, dangerous goods are transported all across the country in order to maintain the quality of life for Canadians. However, when dangerous goods are transported there are safety requirements that must be obeyed. 

In order to prevent unfortunate accidents, ensure public safety and protect those handling and transporting dangerous goods, the Transportation of Dangerous Goods Act, 1992 was established. From defining dangerous goods to setting penalties and reasonable emergency measures, the TDG Act provides a complete guide on how to handle and transport dangerous goods.

In this post, we will take a closer look at what you need to know if your business will receive or ship dangerous goods with a focus on the potential consequences of TDG violations. 

Federal Regulations

Anyone who handles or transports dangerous goods must complete a TDG training either online or in-person along with having a valid employer-issued Transportation of Dangerous Goods (TDG) Certification. Failure to comply with dangerous goods regulations can lead to serious penalties. 

Defining Dangerous Goods

The TDG Act defines dangerous goods as “products that are inherently dangerous whether or not they are in transport” that falls into any one of the following nine classes:

  • Explosives
  • Gases
  • Flammable and combustible liquids 
  • Flammable solids 
  • Oxidizing substances
  • Poisonous and infectious substances
  • Radioactive materials 
  • Corrosives
  • Miscellaneous products, substances or organisms that are considered to be dangerous to life, health, property or the environment. 

Handling Dangerous Goods 

When it comes to transporting dangerous goods, the TDG Act has outlined regulations that ensure everyone responsible for the handling, loading and transporting of dangerous goods is safe and trained to do so. 

The term "handling" is defined as the "loading, unloading, packing or unpacking of dangerous goods in a means of containment or transport for the purposes of, in the course of or following transportation and includes storing them in the course of transportation". This definition encompasses a wide range of activities and makes it clear that the handling of dangerous goods is not limited to the actual process of loading and unloading them.

Dangerous Goods Safety Marks & Packaging

Packaging is a critical aspect of transporting dangerous goods, as it helps to ensure that no harm comes to people or property. In the absence of a specific requirement, the general guidelines stipulate that dangerous goods must be packaged in a way that prevents emissions or discharges that could threaten life, health, property or the environment. Respecting safety marks is fundamental to limiting the hazards associated with transporting dangerous goods. 

Accordingly, TDG regulations include a provision that dangerous goods must have safety marks and documents to convey the nature of any potential dangers to first responders and handlers. Relatively small contaminants (450L or less) must be clearly labeled, while large shipments in bulk containers must be placarded. 

Transport Canada Oversight & Safety Standards

According to the Act, every person engaged in the handling, and transportation must be trained in the aspects applicable to their assigned duties. Without adequate training, workers may not be able to select the proper packaging for a consignment or properly label and document it. Adequate training is essential to ensure that dangerous goods are safely shipped and handled.

In order to promote public safety, federal inspectors have the authority to inspect any consignment they believe is involved in the movement of dangerous goods and ensure that any person whose duties include the handling of dangerous materials has received appropriate TDG training.


The penalties for not complying with TDG guidelines, such as a lack of TDG certification, negligent practices, or making a false or misleading statement to an inspector, are substantial.  

Penalty provisions provide for: 

  • A fine of up to $50,000 for a first offense,
  • Fines of up to $100,000 subsequent offences,
  • Up to 2 years of imprisonment for indictable offenses

The TDG Act includes provisions for penalties that may be imposed by a court in addition to the other penalties stated in the TDG Act. These penalty provisions can include prohibiting a person from engaging in an activity regulated by the TDG Act, requiring a person to compensate others, repair damage to the environment or contribute to research in respect of the transportation of dangerous goods. 

The penalties that may be imposed by a court under the TDG Act are designed to ensure that those who engage in activities regulated by the TDG Act do so in a safe and responsible manner. In determining the penalties to be imposed, the court will consider the nature and gravity of the offense, as well as the circumstances surrounding the offense.
