Time limits for appealing a Workplace Safety and Insurance Board (WSIB) decision
There are strict time limits for appealing all WSIB decisions. You have 30 days from the decision date to appeal Work Reintegration (WR)/return to work, re-employment, and Work Transition (WT)/labour market re-entry decisions, and six months from the decision date to appeal any other decisions, to an Alternate Resolution Officer (ARO).
If the appeal period is missed, you may have lost your right to appeal as an extension to appeal is granted only on very limited grounds. You should still file an appeal as quickly as possible, and contact the Office of the Employer Adviser (OEA) for advice.
ARO decisions must be appealed within six months of the decision date to the Workplace Safety and Insurance Appeals Tribunal (WSIAT).
