​Classification according to WHMIS-1988

The classification list provided in this document was compiled in response to requests for information concerning classifications under federal legislation on controlled products. Please note that this is not an exhaustive list of hazardous products according to WHMIS 1988.

This classification was established by CNESST personnel to the best of their knowledge based on data obtained from scientific literature and it incorporates the criteria contained in the Controlled Products Regulations (SOR/88-66). It does not replace the supplier’s classification which can be found on its Material Safety Data Sheet.

Since the list contains many product names (3091), it is arranged alphabetically, according to the first letter of the name. Click on the letters below to access the product. The classification under the Controlled Products Regulations (SOR/88-66) will be displayed until the end of the transition period on December 1, 2018.
