WHMIS stands for the “Workplace Hazardous Materials Information System”. It is a system of resources designed to reduce the risk from hazardous products in the workplace. It is governed by both Federal and Provincial Laws. Federal law (The Hazardous Products Act and The Controlled Products Regulations administered by Health Canada) require suppliers (including distributors and importers) to provide labels and material and safety data sheets (MSDS) with the WHMIS controlled products (substances that meet hazard criteria described in the above regulations) they sell to Canadian workplaces.

The Health Canada WHMIS web site is designed to help suppliers meet their obligations under the federal law.
