Hazardous Substance Assessments

Hazardous Substance Assessments are technical documents that describe the classification of chemicals in the different hazard classes outlined in Schedule 2 of the Hazardous Products Act (HPA). These documents have been produced by Health Canada as educational and information resources.

Under the Hazardous Products Regulations (HPR), health hazards must be disclosed on the label of a hazardous product or the container in which the hazardous product is packaged (HPR Part 3). In addition, this information must be disclosed on the Safety Data Sheet (SDS; HPR Part 4). The Hazardous Substance Assessments may be used by suppliers to meet these legislative requirements; however, suppliers are ultimately responsible for the accuracy of their hazardous product label and Safety Data Sheet.

Supplier Responsibilities

Suppliers are responsible for producing SDSs that accurately disclose the hazards associated with products regulated under the HPA. Although the information contained in the Hazardous Substance Assessment may be used by suppliers when developing the SDS, the supplier is ultimately responsible for the accuracy and currency of the SDS. Suppliers may use public information, as well as proprietary information, when developing an SDS. While the classification information included in the Hazardous Substance Assessments can serve as a guide for classifying a product, suppliers must classify their products in accordance with the HPR, based on established scientific principles, and supported by studies and scientific data at their disposal, whether publically available or proprietary. Hazardous Substance Assessments are based solely on publically available information and may not be completely up to date. For this reason, Hazardous Substance Assessments are not used to determine whether an SDS is compliant under the HPA. Health Canada assesses the compliance of SDSs on a case by case basis, and in consideration of the information provided by the supplier to support their classifications.

Terms of use

The information and classifications contained in these Hazardous Substance Assessments are based on publically available sources, such as peer-reviewed literature or reports by international bodies. New information, including proprietary information, could have an impact on the classification of substances or hazardous products containing them. It is the responsibility of the supplier to ensure the accuracy, sufficiency, and reliability of their hazardous product classification.
