Chemical Substances (NSN & DSL)

The Canadian Environmental Protection Act (CEPA) was passed in 1999 to promote sustainable development by preventing pollution, and protecting human health and the environment from risks associated with toxic substances. CEPA defines “toxic” substances as those that may have harmful effects on the environment, could be dangerous to the environment that life depends on, or could be dangerous to human health.

Under CEPA, all chemical substance new to Canada must be assessed for human health and environmental risks. Any substance not listed on the Domestic Substances List (DSL) is considered a new substance and subject to Canada’s New Substance Notification Regulations (NSNR). NSNR apply to chemicals, polymers, biochemicals, biopolymers and animate products of biotechnology, such as bacteria, fungi, and genetically modified fish and livestock.
