The New Substances program consists of officials from Environment and Climate Change Canada and Health Canada. It is responsible for administering the New Substances Notification Regulations (Chemicals and Polymers) and the New Substances Notification Regulations (Organisms) [NSNR] made under the Canadian Environmental Protection Act, 1999 (CEPA). These regulations ensure that no new substances (chemicals, polymers or living organisms) are introduced into the Canadian marketplace before undergoing ecological and human health assessments, and that appropriate control measures have been taken, when required.
In September 2001, the New Substances Notification Regulations (NSNR) of the Canadian Environmental Protection Act, 1999 (CEPA) came into effect for substances in products regulated by the Food & Drugs Act. Substances affected include those used in pharmaceuticals, medical devices, cosmetics and personal care products, veterinary drugs, food additives, novel foods, biologics (including genetic therapies) and natural health products.
