Musculoskeletal Disorders & Ergonomics


According to the Workplace Safety and Insurance Board (WSIB), MSDs represent over 40% of all lost-time compensation claims in Ontario. The combined direct and indirect costs are conservatively estimated to be $19 billion from 1996-2006.

Left unaddressed, MSDs threaten both worker health and safety and the province's economic performance. Preventing MSDs can help workplaces to reduce costs, boost productivity, improve product and service quality and stimulate innovation.
