Are appeal deadlines in WSIB letters firm?
Yes, the appeal deadlines are firm. If you miss the deadline, you will usually not be allowed to proceed with your appeal. Do not wait until the last minute if you intend to appeal a decision. In some limited circumstances, however, the time limits may be extended. For more information, see OWA Fact Sheets 24 and 25 called Appealing to WSIB and Appealing to WSIAT.
