Assessment and Management of New Substances in Canada

Welcome to the New Substances (NS) Program homepage. This website is intended to aid those individuals or companies that are required to notify new substances regulated under the Canadian Environmental Protection Act, 1999 (CEPA 1999) (the Act) and to provide general information on the NS program.

The NS program is responsible for administering the New Substances Notification Regulations (Chemicals and Polymers) [NSNR (Chemicals and Polymers)] and the New Substances Notification Regulations (Organisms) [NSNR (Organisms)] of the Canadian Environmental Protection Act, 1999 (CEPA, 1999). Collectively known as the Regulations they are an integral part of the federal government's national pollution prevention strategy. As part of the "cradle to grave" management approach for toxic substances laid out in the Act, the Regulations were created to ensure that no new substances (chemicals, polymers or animate products of biotechnology) are introduced into the Canadian marketplace before an assessment of whether they are potentially toxic has been completed, and any appropriate or required control measures have been taken.

Any company or individual who plans to import or manufacture a substance subject to notification under the Regulations must provide Environment Canada with a New Substances Notification (NSN) package containing all information prescribed in the Regulations prior to import or manufacture. The type of information required and the timing of the notification will depend on such factors as the type of substance, the quantity that will be imported or manufactured, the intended use of the substance and the circumstances associated with its introduction.

When Environment Canada receives a NSN Package from a company or individual proposing to import or manufacture a new substance, a joint assessment process is carried out with Health Canada to determine whether there is a potential for adverse effects of the substance on the environment and human health. To facilitate this assessment, the NSN Package must contain all required administrative and technical data, and must be provided to the NS program, New Substances Division at Environment Canada prior to the manufacture or import of the substance.

The assessment time limit is typically 60 days, but it varies from 5 to 120 days depending on the type of substances and quantities which the companies want to import or manufacture.

When this process identifies a new substance that may pose a risk to human health or the environment, CEPA 1999 empowers Environment Canada to intervene prior to or during the earliest stages of its introduction into Canada. This ability to act early makes the NS program a unique and essential component of the federal management of toxic substances.

International activities are undertaken within the NS program to support effective and efficient decision-making about human health and the environment by seeking common ground in international efforts. Such initiatives further the Canadian Environmental Protection Act's principles of pollution prevention and sustainable development.
