Approach for a Subset of Inorganic and Organometallic Substances

As a part of the Chemicals Management Plan (CMP), the Government of Canada assesses and manages, where appropriate, the potential health and ecological risks associated with substances prioritized for action under the Canadian Environmental Protection Act, 1999 (CEPA 1999).

In April 2018, the Government of Canada published a proposed Chemicals Management Plan Approach for a Subset of Inorganic and Organometallic Substances. The list of substances covered under this initiative can be found within the approach document.

This approach addresses 59 inorganic and organometallic substances that were identified as priorities for assessment as they met the categorization criteria under subsection 73(1) of CEPA 1999, were considered a priority based on other human health concerns or were identified for further consideration following prioritization of the Revised In Commerce List (R-ICL).

This approach identifies the inorganic and organometallic substances for which assessment activities can be considered as having already taken place under CEPA 1999, and proposes that, as such, these substances not undergo further assessment at this time. Addressing these substances in this way will facilitate focusing attention on those substances or groups that have not yet been subject to assessment.

Additional assessment or management activities may be undertaken if new hazard or exposure information becomes available which may impact previous risk analyses for these substances. This information may be identified through international activities, further information gathering activities, or results of risk management activities including performance evaluation and subsequent changes to risk management.

Any person may, within 60 days of publication of this approach, file with the Department of the Environment, written comments on this proposed approach. All comments must cite the approach title and be sent to the Executive Director, Program Development and Engagement Division, Department of the Environment, Gatineau, Quebec K1A 0H3, by fax to 819-938-5212, or by email to

In accordance with section 313 of CEPA 1999, any person who provides information in response to this publication may submit with the information a request that it be treated as confidential.
