1. What Is WHMIS – A Detailed Description

WHMIS stands for Workplace Hazardous Materials Information System – Canada’s national system for providing information on the safe use of hazardous products in the workplace.
If you live or work in London, Ontario, getting your WHMIS certification is essential for staying compliant with Canadian regulations and ensuring workplace safety.
WHMIS is built on three main components. Labels clearly identify hazardous products and outline key safety information at a glance.
Safety Data Sheets (SDS)—formerly known as MSDS—are detailed documents that explain the hazards, precautions, and first aid measures related to a product.
Finally, worker education and training ensures that employees understand how to read labels and SDS sheets, and know how to respond appropriately in case of exposure or an emergency.
The regulations outlined in WHMIS need to be followed. It is a law. Under this law, workers, employers, and suppliers have specific responsibilities.
Workers must complete WHMIS training and keep their certification up to date. They are expected to understand how to read labels and SDS sheets and report any missing or unreadable labels to their supervisor.
Employers are responsible for providing WHMIS training to all relevant staff, ensuring that hazardous products are properly labelled, and making SDS sheets easily accessible in the workplace.
Suppliers, including manufacturers, importers, and distributors of hazardous materials in Canada, must label controlled products according to WHMIS standards and supply up-to-date SDS sheets to their customers.
2. Why Is WHMIS Important?

4. Brief History of WHMIS

WHMIS became a law in Canada on October 31, 1988. Most of the requirements surrounding WHMIS were incorporated into the Hazardous Materials Information Review Act.
WHMIS was put together by a committee made up of representatives from the government, industries, and workers to make sure that it had the best interests of each group in mind.
The regulations in the act include:
- Hazardous Materials Information Review Regulations
- Hazardous Materials Information Review Act Appeal Board Procedures Regulations
- Ingredient Disclosure List
- Controlled Products Regulations
Controlled products refer to any products, materials, and substances that are regulated by WHMIS legislation. These products are grouped into the six WHMIS classes.
WHMIS regulations are enforced by different agencies depending on whether you are a federal, provincial, or territorial worker.
Federal workers:
They are regulated by the Labour Branch of Human Resources Development Canada.
Provincial or Territorial workers:
They are regulated by the agency responsible for occupational health and safety in your province or territory. For example, if you work in Ontario, then the Ministry of Labour, Immigration, Training and Skills Development is responsible for regulating WHMIS.
