Under the Canadian Environmental Protection Act, 1999 (CEPA 1999), the Government of Canada uses a preventative approach to managing the risks new substances may pose to humans or to the Canadian environment.
Under the New Substances Program, Health Canada and Environment and Climate Change Canada examine the potential risks to Canadians and their environment before the substances enter the Canadian marketplace.
The New Substances Program is responsible for administrating the New Substances Notification Regulations (Chemicals and Polymers) and the New Substances Notification Regulations (Organisms) of CEPA 1999. These regulations were created to ensure that no new substances (chemicals, polymers or organisms) are introduced into the Canadian marketplace before undergoing ecological and human health assessments. A substance is considered to be new to Canada if it is not listed on the Domestic Substances List (DSL).
Who is required to notify?
Any company or individual who intends to import or manufacture a new or flagged substance in Canada is required to notify under the New Substances Notification Regulations (NSNR).
What is a new or flagged substance?
Any substance not included on the DSL or that appears on the DSL and is flagged with a Significant New Activity (SNAc) notice or a Reduced Regulatory Requirement (RRR) is subject to the NSNR. These regulations apply to chemicals, polymers, biochemicals, biopolymers and biotechnology (living organisms). View the Significant New Activity Publications under the Canadian Environmental Protection Act, 1999 . View the Policy on the Use of Significant New Activity Provisions of the Canadian Environmental Protection Act, 1999.
How to notify?
The NSNR require that any person who intends to import or manufacture a substance subject to notification under the regulations must submit a New Substances Notification (NSN) package to Environment and Climate Change Canada, containing all information prescribed in the regulations, prior to import or manufacture of the substance.
For guidelines relating to notification and testing of new substances, please consult:
- Guidance Documents for Biotechnology (Living Organisms)
- Guidance Documents for Chemicals and Polymers
Advisory notes are available to clarify certain aspects of the NSN Program for the benefit of individuals responsible for complying with the NSNR:
- Advisory Notes: Biotechnology (Living Organisms)
- Advisory Notes: Chemicals and Polymers
- Advisory Notes: Nanomaterials
For information regarding the preparation of NSN packages, please consult:
- Notification Forms for Chemicals, Polymers, Biochemicals, and Biopolymers
- Notification Forms for Biotechnology (Living Organisms or Micro-organisms)
Additional information and forms required for the notification process can be acquired from the New Substances Notification web page.
When Environment and Climate Change Canada and Health Canada suspect that a new substance may meet one or more of the criteria of section 64 of CEPA 1999, control measures are imposed to minimize any risks to the environment or human health. Additionally, when it is suspected that a SNAc in relation to a substance may result in the substance meeting one or more of the criteria of section 64 of CEPA 1999, a notice is issued to ensure that adequate additional information is provided by the notifier or any other proponent who wishes to manufacture, import or use the substance for activities not specified by the notice. These orders are published in the Canada Gazette.
Consult the CEPA Environmental Registry to view details on published orders.
