2. Tell the WSIB you want to appeal

To  a decision, you must submit an Intent to Object Form.

You can appeal up to 3 decisions on the same Intent to Object Form. If there's more than 3 decisions that you want to appeal, you can submit more forms.

The Intent to Object Form is on the Workplace Safety and Insurance Board (WSIB) website. Or you call and ask the WSIB to mail you one. Call 1-800-387-0750. For TTY, call 1-800-387-0050.

Fill out your Intent to Object Form

The form has instructions about how to fill it out. The basic information you must give is:

  • your WSIB 
  • the date of the decision that you disagree with
  • the reasons why you disagree

You do not need to give detailed reasons why you disagree. For example, you can say:

“I disagree with the decision because the decision-maker got the law and the facts wrong”.

You should send in detailed reasons later with your Appeal Readiness Form. See Step 3.

Someone can help you fill out the form. But you must sign the form if you send in a paper version. If you submit the form online, you type in your name.

Send in your Intent to Object Form

You can fill out and submit the Intent to Object Form online.

If you fill out a paper form, it's best to fax it with any supporting documents to the WSIB. The fax number is 1-888-313-7373.

Your can also mail your form and copies of your documents to:

Workplace Safety and Insurance Board
200 Front Street West
Toronto, Ontario M5V 3J1

Send your form as soon as possible after you:

  • get your decision letter, and
  • decide that you disagree with the decision.

Even if you're not sure if you disagree with the decision, it's a good idea to send in the Intent to Object form. It's free. You can end your appeal at any time and it will not cost you money.

Try to get legal help with your appeal.

Send the form before the deadline

How much time you have to send in the Intent to Object Form is different based on the type of decision. The deadline is:

  • 30 calendar days for a decision related to returning to work
  • 6 months for any other type of decision

Your decision letter says how much time you have to appeal a decision.

Submit the form before the deadline, even if you're waiting for an answer about a . The WSIB is very strict about this deadline.

You can submit documents you're using as with the form or later if you do not have them ready by the deadline.

If you miss the appeal deadline

You might lose your right to appeal. But the WSIB can extend the deadline to appeal your decision.

Write to the WSIB and explain why your Intent to Object Form is late.

When deciding if they'll extend the deadline, the WSIB may look at whether:

  • you or a close family member was having serious health problems
  • you had to leave the province or country because you were very sick or someone in your family was very sick or died
  • no one told you about the time limit to appeal

The reasons listed above are just examples. The WSIB can consider other reasons as well. But you need to have a very good reason why you did not appeal the decision on time.
