Appeal Time Limits

Time limits for appealing a WSIB decision

There are strict time limits for appealing all WSIB decisions. You have 30 days from the decision date to appeal WR, re-employment or, WT decisions, and six months from the decision date to appeal any other decision to an 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 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 WSIAT.
