Transportation of Dangerous Goods
TDG History
In November 1979, the second most important dangerous goods transportation accident in Canada occurred in Mississauga, Ontario. A freight train derailed in a densely populated area and a dozen different dangerous goods were released.
Despite the importance of the accident, no one died. However, over 200,000 people were evacuated for several days.
The first TDG Act was created in 1980. Its area of application was described in terms of the National Transportation Act and was intended to cover "surface" transportation, which is road and rail.
The first TDG Regulations were published in 1985. The Regulations were often modified; however, in general, they appeared to work.
Finally, a near final version was proposed in August 2000, in Part I of the Canada Gazette. A year of public consultation followed on the proposed text. On August 15, 2001, the "final" version was published in Part II of the Canada Gazette and the new regulations came into force in August.

TDG FACTS
Once trained, how long is my certificate valid for?
A TDG certificate is valid for 3 years.
If I change employers / jobs, do I have to retrain?
According to the TDG Regulations a TDG certificate is not transferable between employers. This means that if a trainee changes employers, they will need to be re-certified by the new employer and possess a training certificate with the new employer's name, address etc.
Where do I keep my certificate?
A TDG training certificate is required to be kept on the individual when they are working. Most people keep it in their wallets. If a Transport Canada inspector requests to see your TDG certificate while you are working, you are required to show it to them.
What happens if I do not have a valid TDG certificate?
If you do not have a valid TDG 'Clear Language' Certificate, you are in violation of the regulations. Non-compliance of transporting dangerous goods is usually identified through inspections carried out on the highway. Convictions may start at $500.00 and up to $50,000.00 for a first time offense, Second time offense up to $100,000.00
