The WSIB derives its powers and duties from its governing legislation, the Workplace Safety and Insurance Act, 1997 (WSIA).
The purpose of this policy is to outline the scope of the WSIB's powers and duties.
The WSIB has full and exclusive jurisdiction to determine
- how the WSIA should be interpreted, including whether an injury, disease, or death is work-related
- whether benefits are payable
- whether an industry falls within the scope of the WSIA
- the amount of premiums to be paid by employers
- whether a worker is co-operating in reaching his or her maximum medical recovery
- whether workplace parties (worker and employer) comply with their duty to co-operate in work reintegration
- whether an employer has fulfilled his or her obligation to re-employ a worker, and
- whether to provide a worker with a work transition assessment/plan.
Practice and procedure
The WSIB has the power to determine its own policies, practices and procedures. It is not bound by legal precedent, legal rules of evidence, or the Statutory Powers Procedures Act. It must make its decisions based on the merits and justice of a case, see 11-01-03, Merits and Justice.
A policy for the purpose of s.126, is any information contained in the Operational Policy Manual or Employer Classification Manual, and if approved after July 1, 2001, it must be minuted.
Power to reconsider
The decisions of the WSIB are final, and there is no recourse to the courts for matters which are covered by the WSIA. However, the WSIB also has the power to reconsider and change any of its decisions at any time it considers it appropriate to do so, see 11-01-14, Reconsiderations of Decisions.
Decisions may be appealed to the Workplace Safety and Insurance Appeals Tribunal (WSIAT) after the WSIB’s internal appeal mechanisms have been exhausted. WSIAT must apply the WSIB’s policies to their decision-making. There is no further appeal of WSIAT decisions to the courts.
This policy applies to all decisions made on or after February 15, 2013, for all accidents.
