Current Regulations

New Substances Notification Regulations (Chemicals and Polymers) (SOR/2005-247)

The New Substances Notification Regulations (Chemicals and Polymers) (the Regulations) are the culmination of an extensive stakeholder consultation on the chemicals and polymers portion of the existing New Substances Notification Regulations (NSNR) and the New Substances Program (NS Program). The purpose of the New Substances Notification multistakeholder consultative process was to use the experience of stakeholders to improve the effectiveness and efficiency of the new substances notification and assessment process for chemicals and polymers, while maintaining high standards in the protection of the environment and human health. The Regulations implement consensus-based recommendations from these consultations. The existing NSNR will be repealed and replaced with these Regulations and the New Substances Notification Regulations (Organisms) pursuant to subsections 89(1) and 114(1) of the Canadian Environmental Protection Act, 1999 (the Act).
