Workers' compensation and benefits policy

Workers' compensation is a form of insurance providing wage replacement and medical benefits to workers injured in the course of their employment. Eligibility for, and awarding of, benefits to injured workers are determined by workers’ compensation boards, which are funded through employer premiums. IWH research explores trends in compensation benefits, including benefit adequacy and equity, as well as the effects of compensation policy design on injury and illness prevention.

Ontario Life After Workplace Injury Study: What we've learned so far

The Ontario Life After Workplace Injury Study (OLAWIS) is looking at the long-term health and labour market outcomes of workers disabled by work injury or illness after they are no longer receiving benefits or services from the Workplace Safety and Insurance Board. As part of the study, over 1,130 eligible claimants were interviewed at 18 months post-injury and asked about a wide range of factors, including their work status and income, physical and mental health, case manager and health-care provider interactions, and employer return-to-work support. In this presentation, Dr. Cameron Mustard shares what the researchers have learned so far about this group of injured workers.
