The TDG training certificate shows that you have been trained to handle, offer for transport or transport dangerous goods safely. Federal rules require it for many jobs in warehousing, trucking, airports and shipping.
Official website ↗Dangerous goods include things like fuels, paints, cleaning products, compressed gases and batteries. Moving them safely takes special knowledge. Transport Canada's TDG Regulations say that anyone who handles, offers for transport or transports these products must be trained and hold a training certificate.
Your employer issues the certificate. It is not a licence from the government. Your employer must make sure your training fits the work you actually do. A forklift operator in a warehouse may learn different things than a truck driver or an airport ground crew member. This is why the certificate is tied to your job and your workplace.
At the end of the course, you complete a written or online test. It checks that you understand classification, labels, documents and emergency steps. Many courses let you review your answers and try again if you do not pass the first time.
Your TDG certificate does not last forever. It must be renewed with refresher training before it expires. It must also be updated if your job duties change or the rules change significantly. Your employer keeps a record of your training. Keep your own copy as well, because you may need it when you change jobs.
