Glossary of Terms
This list includes some of the abbreviations you might hear mentioned in the workers’ compensation system, and may see written in WSIB case files. As the substantive provisions of legislation pertaining to a particular case depend on the date of injury or disease, this list includes terminology associated with any of the four Acts that may continue to apply to a workers’ compensation claim:
- The Workplace Safety and Insurance Act, 1997 (covering accidents and diseases that occurred on or after January 1, 1998)
- the pre-1997 Workers’ Compensation Act (covering accidents and diseases that occurred between January 2, 1990 and December 31, 1997)
- the pre-1989 Workers’ Compensation Act (covering accidents and diseases that occurred between April 1, 1985 and January 1, 1990, as well as deaths during this same period regardless of the date of the accident) and
- the pre-1985 Workers’ Compensation Act (covering accidents and diseases that occurred prior to April 1, 1985).
