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.

How to appeal a WSIB decision

Write to the operating level decision-maker to object, and include any new information to support your objection. The decision-maker will review the concerns raised and may reconsider his/her decision.

If the decision is unchanged, a copy of the claim file will be sent to you, along with an Objection Form that must be completed and returned to the WSIB to proceed with the objection. The worker’s claim file will be provided in two sections – health care and non-health care.
