Significant New Activity orders and notices of the Chemicals Management Plan

Significant New Activity approach for existing substances

As part of the Chemicals Management Plan, the Domestic Substances List (DSL) may be amended from time to time to indicate that the Significant New Activity (SNAc) provisions of the Canadian Environmental Protection Act,1999 (CEPA 1999) apply to some existing substances.

An amendment to the DSL will be made if Environment and Climate Change Canada (ECCC) or Health Canada (HC) suspect that a SNAc involving a substance may result in the substance being released in amounts or conditions that could result in it meeting one or more criteria set out in section 64 of CEPA 1999. Adequate additional information will be required from the proponent who wishes to manufacture, import or use the substance for activities indicated in the order applying the SNAc provisions. The additional information will allow ECCC and HC to assess the potential environmental and human health risks associated with the new activities before they are undertaken.

Please note that SNAc provisions do not apply to the manufacture or importation of an existing substance for a use that is regulated under Acts of Parliament listed in Schedule 2 of CEPA 1999, including the Pest Control Products Act, the Fertilizers Act and the Feeds Act.

Please also note that SNAc provisions do not apply to the manufacture or importation of an existing living organism for a use that is regulated under Acts of Parliament listed in Schedule 4 of CEPA 1999, including the Pest Control Products Act, the Seeds Act, the Fertilizers Act, the Feeds Act and the Health of Animals Act.

Review of current Significant New Activity orders and notices

ECCC and HC have initiated a review of SNAc orders and notices currently in place under CEPA 1999.

Purpose and rationale of the review

Since publication of the first SNAc notice in 2001, policies and practices have evolved, particularly with respect to the nature and scope of SNAcs, as well as the wording used to identify "significant new activities". This review is being undertaken to ensure that current SNAc orders and notices are in step with current information, policies and approaches.

The SNAc review will apply all elements of the Policy on the Use of Significant New Activity Provisions of the Canadian Environmental Protection Act, 1999 (published in December 2013). Resulting changes to SNAcs are expected to provide greater clarity of scope and improved ease of compliance by industry.

Proposed scope of the review

The review will consider SNAcs currently in place and will:

  • review completed risk assessments for substances subject to a SNAc and other available information to confirm that the rationale for applying the SNAc is consistent with current policies
  • confirm that the information requested in the SNAc is consistent with current SNAc policy and approach
  • review wording to ensure clarity and consistency with current approach to drafting of SNAc requirements

The review of SNAcs will be undertaken by grouping SNAcs either by substance type or by the type of "new activities" described. This will facilitate an efficient review process and allow for consistency in application of new approaches to similar SNAcs. Specific SNAcs may be reviewed earlier than scheduled, depending on stakeholder input.

Outcome of the review

Following the review process, there may be no changes needed for certain SNAcs or, for others, rescissions or amendments may be warranted. As the review will be implemented via a phased approach, information on the results of the review process will be published on an ongoing basis as elements of the review are completed. Elements of this review may be subject to external consultation. Please contact us to communicate your interest in participating in these consultations.

After considering comments received, a notice or order may be published (as appropriate) to indicate that the SNAc provisions no longer apply to certain substances or that the content of published SNAcs has been revised.

If you have any questions or comments on this review or would like to submit information that could be relevant to the review, please contact us. Indicate on the envelope or in the subject line "Review of current Significant New Activity orders and notices".
