Welcome to the future home of WHMIS Training Ontario
The Workplace Hazardous Materials Information System (WHMIS) in Ontario is a comprehensive national standard designed to ensure that employers and workers have the necessary information to safely manage hazardous materials in the workplace. Established in 1988 and updated to WHMIS 2015, the system aligns with the Globally Harmonized System (GHS) of Classification and Labelling of Chemicals. WHMIS 2015 introduces standardized hazard symbols, signal words, and hazard statements to improve hazard communication. The system encompasses four key elements: product classification, labels, safety data sheets (SDSs), and worker education. Employers are required to ensure that hazardous products are properly labelled, SDSs are accessible, and workers receive appropriate training to handle these materials safely.
In Ontario, WHMIS is enforced under the Occupational Health and Safety Act (OHSA) and the Workplace Hazardous Materials Information System Regulation (R.R.O. 1990, Regulation 860). These regulations mandate that employers obtain health and safety information about hazardous products from their suppliers and use that information to train their workers. The Ministry of Labour, Training and Skills Development is responsible for enforcing both federal and provincial WHMIS legislation in Ontario, ensuring compliance and protecting worker health and safety .
