Compliance Alert: New TDGR Training Rules Take Effect in February

The system you use to provide workers Transportation of Dangerous Goods Regulations (TDGR) training may become obsolete on February 9, 2022, when Transport Canada’s new Competency-Based Training requirements take effect.


Under current rules (Part 6 of the TDGR), any person who handles, offers for transport or transports dangerous goods must be “adequately trained” in their dangerous goods tasks and receive a certificate of training. The new TDGR removes the vague and confusing term “adequately trained” and replaces it with the requirement that trainees be competent for TDG tasks. To accomplish this, they must receive both general awareness and function-specific training and assessment meeting the requirements of CAN/CGSB-192.3-2020, a CBT standard for transporting dangerous goods developed by a federal government organization called the Canadian General Standards Board (CGSB).

Instead of the “certificate of training” required under current rules, trainees must receive a “certificate of competence” documenting successful completion of required TDGR training. While it would include the same basic information as the certificate of training, the new certificate of competency may be signed electronically and must list codes denoting the functions for which competency was achieved.


Certificates of competency will have the same shelf life as certificates of training—that is, 3 years for road, rail and marine, and 2 years for air. But once the certificate of competency expires, employers must make an assessment to determine whether retraining is necessary. They also must provide supplementary training in response to changes in TDGR requirements or employees’ functions.
