New substances: Chemicals and polymers
The New Substances Notification Regulations (Chemicals and Polymers) [NSNR (Chemicals and Polymers)] help protect Canadians and the environment, as they allow for the assessment of new chemicals and polymers prior to their introduction into the Canadian marketplace above prescribed thresholds. Following a New Substances Notification (NSN), Environment and Climate Change Canada and Health Canada carry out a joint assessment process to determine whether there is a potential for risk to the environment and human health. When potential risks are identified, the Canadian Environmental Protection Act, 1999 (CEPA) empowers the Minister of Environment and Climate Change to impose control measures.
If you plan to manufacture or import new chemicals or polymers subject to notification under the NSNR (Chemicals and Polymers), you are required to provide information to Environment and Climate Change Canada.
