This introductory course begins by exploring the history of the compensation system in Ontario and the development of compensation legislation and the general principles of the system. Participants will learn how the Workplace Safety and Insurance Board (WSIB) determines whether an injury is compensable and learn about some workplace injuries and occupational illnesses. The course covers how to properly file a claim, and includes the timelines that are applicable. Worker and Employer obligations are covered as well as roles and responsibilities with respect to work reintegration. The WSIB work reintegration policies are discussed and the new direction that the Board is taking with respect to returning workers to their pre-injury job with the injury employer. Shared responsibilities are also discussed and ways in which unions should participate in work reintegration are explored. Leading research shows that a collaborative and cooperative approach to work reintegration following the hierarchy of jobs, beginning with pre-injury job, leads to better outcomes for both workers and employers. Protections under other legislation are also discussed should a work reintegration plan not provide sufficient protection to a worker in a work reintegration plan. Finally, participants discuss how to effectively implement the new skills that have been acquired through this course and what additional resources are available.
