Transportation of Dangerous Goods Act, 1992

The Transportation of Dangerous Goods Act, 1992 (Loi de 1992 sur le transport des marchandises dangereuses) is a Canadian federal statute. Introduced in the 34th Canadian Parliament, and receiving royal assent on June 23, 1992, the act regulates the transportation of dangerous goods in the country.

The TGDA has an "Offences and Punishments" passage in which are detailed liabilities "on indictment to imprisonment for a term not exceeding two years", and that "Proceedings by way of summary conviction may be instituted at any time within, but not later than, five years after the day on which the subject matter of the proceedings arose." The TGDA falls under the control of the Minister of Transport.

The Hazardous Waste Manifest form is mandated by the TDGA.
