The appropriate route depends on the decision and the rules that apply. A departmental review is not necessarily available for every issue or at every stage; check the decision letter and ask VAC or a representative to confirm.
Identify the specific error
Explain whether key evidence was overlooked, facts were misunderstood, information has changed or the applicable policy appears to have been misapplied.
Provide focused evidence
Organize new or clarifying evidence and explain exactly how it addresses the reason for the decision.
Keep proof of submission
Save the request, attachments, delivery confirmation and any reference number.
Check other options at the same time
Do not allow an uncertain departmental process to cause you to miss a statutory or tribunal deadline. Get advice promptly.
