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), re-employment or work transition (WT) decisions, and six months from the decision date to appeal any other decision to an appeals resolution officer (ARO).

Although the WSIB’s appeal guidelines generally allow an appeal to be filed within one year of the decision, employers should continue their best efforts to file an appeal within the stated time limits. If the appeal period is missed, file your appeal as soon as possible. Employers who encounter problems with appeal periods should contact the Office of the Employer Adviser (OEA) for assistance. The WSIB’s “Appeals System Practice & Procedures” document is on the WSIB’s website.

ARO decisions must be appealed within six months of the decision date to the Workplace Safety and Insurance Appeals Tribunal (WSIAT).
