One mistake in transporting dangerous goods can lead to massive fines, legal trouble—or worse, a serious accident. Between 2020 and 2022 , Canada saw over 2,500
The Transportation of Dangerous Goods Act (TDG) is essential to the transportation industry. Through airports, trains, highways, and harbours, dangerous goods are transported across the country to maintain the quality of life for Canadians. However, when dangerous goods are transported, safety requirements must be obeyed.
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 handling and transporting dangerous goods.
This post will examine the possible penalties for TDG violations if your business receives or ships dangerous goods.
TDG Training Certificate: Requirements, Validity & Recordkeeping
Under the Transportation of Dangerous Goods (TDG) Regulations, every employee who handles, offers for transport, or transports dangerous goods must be adequately trained and hold a valid TDG training certificate.
What Must a TDG Certificate Include?
A TDG training certificate must contain:
Employee’s name
Employer’s name and address
Date of issuance
Expiry date
Signature of employer
How Long Is TDG Certification Valid?
Certification validity depends on the mode of transport:
Road, Rail, Marine: Valid for 3 years
Air Transport: Valid for 2 years
After expiry, retraining is mandatory.
Employer Responsibilities
Employers must:
Ensure employees are trained in duties specific to their role
Maintain training records
Provide proof of certification during inspections
Issue updated certificates upon retraining
Failure to maintain proper TDG certification records may result in fines, administrative penalties, or prosecution.
Understanding the TDG Regulations – Parts & Schedules Explained
The TDG Regulations are structured into multiple Parts and Schedules that govern classification, documentation, packaging, emergency response, and reporting.
Key Parts of the TDG Regulations
Part 2: Classification
Part 3: Documentation
Part 4: Dangerous Goods Safety Marks
Part 5: Means of Containment
Part 6: Training
Part 7: Emergency Response Assistance Plans (ERAP)
Part 8: Reporting Requirements
TDG Schedules
Schedule 1: Lists dangerous goods by UN number
Schedule 2: Special provisions
Schedule 3: Marine pollutants
Understanding these sections ensures full TDG compliance and reduces enforcement risks.
Classification of Dangerous Goods & Using Schedules
Correct classification determines packaging, labeling, and emergency planning.
The 9 TDG Classes
Explosives
Gases
Flammable Liquids
Flammable Solids
Oxidizers
Toxic & Infectious Substances
Radioactive Materials
Corrosives
Miscellaneous Dangerous Goods
Misclassification can result in serious safety risks and legal consequences.
Schedule 1 of the TDG Regulations provides official classification references using UN numbers.
Transport Canada Oversight & Safety Standards
According to the Act, every person engaged in handling and transportation must be trained in the aspects applicable to their assigned duties. Without adequate training, workers may be unable 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.
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 handling dangerous materials has received appropriate TDG training.
Penalties
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 offence, Fines of up to $100,000 for subsequent offences,
Up to 2 years of imprisonment for indictable offences
The TDG Act penalties that a court may impose 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 regarding the transportation of dangerous goods.
The penalties that a court may impose 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 and the circumstances surrounding the offense.
How are Violations Detected?
TDG violations don’t go unnoticed for long. There are a few ways authorities pick up on non-compliance.
Roadside inspections are one of the most common. If your vehicle is flagged, inspectors will check paperwork, labels, containers, and training records on the spot.
Workplace audits by Transport Canada can also reveal issues—especially if your site stores, handles, or ships regulated goods.
Sometimes, it’s an incident report that triggers action. A spill, fire, or near miss involving dangerous goods often leads to a deeper investigation.
There’s also the chance of someone speaking up. Whistleblowers—usually workers or contractors—can file anonymous complaints that lead to enforcement checks.
In all cases, Transport Canada and federal inspectors take these matters seriously. A simple mistake can lead to a full audit or legal consequences.
Keeping your records clean and your team trained is the best way to avoid surprise visits turning into major penalties.
Federal Regulations
Anyone who handles or transports dangerous goods must complete a TDG training online or in-person, with 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 fall 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 considered dangerous to life, health, property or the environment.
Handling Dangerous Goods
Regarding 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, 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. Without a specific requirement, the general guidelines stipulate that dangerous goods must be packaged to prevent emissions or discharges that could threaten life, health, property, or the environment. Respecting safety marks is fundamental to limiting the hazards of 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 labelled, while large shipments in bulk containers must be placarded.
Emergency Response Assistance Plans (ERAPs)
An Emergency Response Assistance Plan (ERAP) is required for certain high-risk dangerous goods.
When Is an ERAP Required?
An ERAP is mandatory for:
Large quantities of specific hazardous materials
Substances with high explosion or toxicity risks
What Does an ERAP Include?
Emergency response procedures
24/7 technical support
Specialized equipment access
Failure to implement an ERAP when required can result in severe penalties and increased liability.
