Prohibition of Certain Toxic Substances Regulations, 2003 (SOR/2003-99)

The Prohibition of Certain Toxic Substances Regulations, 2003 (hereafter referred to as the Regulations) feature a schedule listing toxic substances subjected to prohibition for manufacture, use, sale, offer for sale and import. The Regulations have been amended in two respects. First, two substances were added to the Schedule in the Regulations: benzidine and its salt (benzidine dihydrochloride) and hexachlorobenzene (HCB). Second, the Regulations include conditions specific to one substance, HCB.

The benzidine and Mirex entries were amended in Schedule 1 to the Canadian Environmental Protection Act, 1999 (CEPA 1999) prior to publication of the Regulations. Benzidine salt (benzidine dihydrochloride) has been added to Schedule 1, to clarify the inclusion of the salt compound of benzidine. The entries for Mirex in Schedule 1 and in Part 1 of Schedule 3 to CEPA 1999 were not consistent. To avoid confusion, the same terminology is now used in both schedules, as well as in the List of Prohibited Toxic Substances of the Regulations. These Regulations replace the Prohibition of Certain Toxic Substances Regulations.
