If you determine you do not meet the reporting criteria of the notice, you may submit one of the following options:
Declaration of Stakeholder Interest
Persons not subject to the notice, but who have information the Government may find useful on a reportable substance(s), are encouraged to submit this information through a Declaration of Stakeholder Interest (SHI) via Environment and Climate Change Canada’s Single Window online reporting system. This may include information regarding activity for another calendar year, activity with a reportable substance under the thresholds or other non-reportable activity. Stakeholder data supplementing a mandatory response to this notice can also be submitted as an SHI.
When providing information through an SHI, please indicate if any of the information is confidential and provide a rationale. Information on data elements generally not expected to be confidential can be found in the Approach to disclose confidential information and promote transparency in chemicals management.
Follow the steps below to submit your SHI. For additional information, please refer to section 17 of the Guidance Manual for instructions on how to submit an SHI.
