The Appeals Resolution Officer (ARO) decision is the final decision of the WSIB. If you disagree with this final decision it can be appealed to the Workplace Safety and Insurance Appeals Tribunal (WSIAT), the external and final level of appeal of worker’s compensation decisions. The letter attached to the decision provides information about how to start an appeal to WSIAT.
Alternatively, you can request a reconsideration of the Appeals Resolution Officer decision. You need to provide a letter to the Appeals Resolution Officer explaining how the request meets the criteria for reconsideration.
The reconsideration criteria are:
- a substantive defect in the decision or the decision-making process that may reasonably affect the outcome;
- failure to properly apply the act or approved WSIB policy;
- significant new evidence that did not exist at the time the decision was made, and that is relevant to the issue(s) under appeal; or
- a typographical error that impacts the decision.
Additional detailed information on the reconsideration process is outlined in the Appeals Services Division Practice and Procedures.
