WHMIS 2015 classification

The classification list provided in this document was compiled in response to requests for information concerning classifications under federal legislation on hazardous products. Please note that this is not an exhaustive list of hazardous products according to WHMIS 2015.

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 Hazardous Products Regulations (SOR/2015-17). It does not replace the supplier’s classification which can be found on its Safety Data Sheet.

Since the list contains many product names (2441), it is arranged alphabetically, according to the first letter of the name. Click on the letters below to access the product lists. The classification under the Controlled Products Regulations (SOR/88-66) will also be displayed for most products until the end of the transition period, on December 1, 2018.

Useful tip: To use the WHMIS product list in a spreadsheet, download the text file containing the WHMIS classification. The key of this file. Please take note that field delimiter is "|" (ascii 124).
