EXPLANATORY NOTE
(This explanatory note is not part of the Significant New Activity Notice.)
Description
This Significant New Activity (SNAc) Notice is a legal instrument adopted by the Minister of the Environment pursuant to section 85 of the Canadian Environmental Protection Act, 1999 (the Act) to apply the SNAc provisions of the Act to the substance defined in the Notice. The Notice is now in force and it has force of law. It is therefore mandatory for a person who intends to use the substance for a significant new activity as defined in the Notice to meet all applicable requirements set out in the Notice.
A SNAc Notice does not constitute an endorsement from the Minister of the Environment, the Department of the Environment or the Government of Canada of the substance to which it relates, nor does it constitute an exemption from any other laws or regulations that are in force in Canada and that may apply to the substance or activities involving the substance.
Applicability of the Significant New Activity Notice
The Notice requires that any person (individual or corporation) engaging in a significant new activity in relation to the substance submit a Significant New Activity Notification (SNAN) containing all of the information prescribed in the Notice at least 90 days prior to using the substance for the significant new activity.
Activities not subject to the Notice
Uses of the substance that are regulated under the Acts of Parliament listed in Schedule 2 of the Act (the Pest Control Products Act, the Fertilizers Act and the Feeds Act) are excluded from the Notice. The Notice also does not apply to substances described in section 3.2 of the Guidance Document for the New Substances Notification Regulations (Chemicals and Polymers).
Activities involving the use of the substance as a research and development substance or a site-limited intermediate or an export-only product are excluded from the Notice. The terms “research and development substance” and “site-limited intermediate substance” are defined in subsection 1(1) of the New Substances Notification Regulations (Chemicals and Polymers).
Information to be submitted
The Notice sets out the information that must be provided to the Minister of the Environment 90 days before the day on which the substance is used for a significant new activity. The Minister of the Environment and the Minister of Health will use the information submitted in the SNAN to conduct a risk assessment within 90 days after the complete information is received.
The information requirements in the Notice relate to general information in respect of the substance, details surrounding its use, exposure information, and toxicity to human health and the environment. Some of the information requirements reference the New Substances Notification Regulations (Chemicals and Polymers).
Additional guidance on preparing a SNAN can be found in section 9.6.2 of the Guidance Document for the New Substances Notification Regulations (Chemicals and Polymers).
Transitional provision
A transitional provision may be included in the Notice to facilitate compliance by persons who may already have imported or manufactured the substance and started activities with it. In such cases, the Notice comes into force immediately; however, during the transitional period, the substance may be used for a significant new activity in quantities not exceeding quantities specified in the transitional provision.
Compliance
When assessing whether or not a substance is subject to SNAc provisions, a person is expected to make use of information in their possession or to which they may reasonably have access. For example, manufacturers are expected to have access to their formulations, while importers or users of a substance, mixture, or product are expected to have access to import records, usage information and the relevant Safety Data Sheets (SDSs).
A company can submit a SNAN on behalf of its clients. For example, in cases where a person takes possession or control of a substance from another person, they may not be required to submit a SNAN, under certain conditions, if their activities were covered by an original SNAN submitted by the person from whom they obtained the substance.
Under subsection 86(1) of the Act, any person who transfers the physical possession or control of a substance subject to a SNAc Notice must notify all persons to whom the physical possession or control is transferred of the obligation to comply with the Notice. A SNAc Notice may specify that subsection 86(1) of the Act does not apply under defined conditions.
A pre-notification consultation (PNC) is recommended for notifiers who wish to consult with the program during the planning or preparation of their SNAN to discuss any questions or concerns they have about the prescribed information and test plans.
For further information, please contact the Substances Management Information Line (substances@ec.gc.ca [email], 1‑800‑567‑1999 [toll-free in Canada], and 819‑938‑3232 [outside of Canada]).
The Act is enforced in accordance with the publicly available Compliance and Enforcement Policy for the Canadian Environmental Protection Act, 1999.
