Information for laboratories using certain toxic substances

The Prohibition of Certain Toxic Substances Regulations, 2012 prevent potential risks of harm to the Canadian environment and human health by prohibiting the manufacture, use, sale, offer for sale or import of the toxic substances listed below, and products containing them, with a limited number of exemptions.

Annual reporting required

The prohibition does not apply to listed toxic substances, or to any products containing them, that are to be used in a laboratory for analysis, in scientific research or as a laboratory analytical standard. Users of the listed toxic substances for the above purposes are required to report certain information to the Minister as soon as feasible before the use of more than 10 grams of any substance in a calendar year.

Separate reports must be submitted every calendar year for each substance. A reporting form is available online to facilitate reporting. The information that must be reported includes:

  • Information respecting the laboratory and person authorized to act on behalf of the laboratory
  • Information respecting the substance and, if applicable, the product in which it is used:
  • For substances:
    • the name of the toxic substance (as listed in the regulations)
    • the anticipated period of its use per calendar year (January to December)
    • the estimated quantity of the toxic substance to be used in each calendar year
    • a brief description of each proposed or actual use
  • For products:
    • the name of the product containing the listed toxic substance
    • the estimated quantity of the product to be used, and
    • the estimated concentration of the listed toxic substance in the product

Updates to the list of prohibited substances

The regulations may be amended from time to time to modify current requirements or to add new substances. If you are using a substance newly added to the regulations in a laboratory for analysis, in scientific research or as a laboratory analytical standard, reports on the use of more than 10 grams in a calendar year are due within 60 days of the coming-into-force of the amended regulations. 

In order to stay informed, please visit the CEPA registry and the Prohibition of Certain Toxic Substances Regulations webpage. You may also send us an email to be added to our distribution list.
