Promoting Prevention Prevention Campaigns The WSIB wants to help make employers and workers more aware of their health and safety responsibilities. We promote health and safety messages through radio, print and television ads so we can reach as many people in Ontario as possible. We also use our campaigns to let everyone know that they can call on us or our health and safety partners for information and help. Health and Safety Events The WSIB sponsors and participates in a number of important health and safety events and initiatives throughout the year. Learn about some key events including the Student Video Contest, Day of Mourning and NAOSH Week.
