The Canadian Environmental Protection Act (CEPA 1999) defines toxic substances as substances that are "entering or may enter the environment in a quantity or concentration or under conditions that: (1) have or may have an immediate or long-term harmful effect on the environment or its biological diversity; (2) constitute or may constitute a danger to the environment on which life depends; or (3) constitute or may constitute a danger in Canada to human life or health." (Section 64). In determining whether a substance should be declared "toxic" under CEPA 1999, the likelihood and magnitude of releases into the environment and the harm it may cause to human health or ecosystems at levels occurring in the Canadian environment are taken into account.
If a substance is found to be toxic according to CEPA, the Ministers recommend that the substance be added to the List of Toxic Substances (CEPA 1999 Schedule 1). Preventive or control actions such as regulations, guidelines or codes of practice, are then considered for any aspect of the substance's life cycle from the research and development stage through manufacture, use, storage, transport and ultimate disposal or recycling. Furthermore, substances determined to be "toxic", persistent, bioaccumulative, anthropogenic, and which are not naturally occurring radionuclides or naturally occurring inorganic substances shall be proposed for implementation of virtual elimination under Section 65 (3) of CEPA 1999.
