How to communicate with the WSIB by email

We need your consent before communicating with you via email in some instances. You can also submit documents and send us messages through your online services account, anytime, anywhere.

Businesses emailing us about your account

Complete the email consent form to add an email address as an authorized contact on your account and then email the completed form to, or submit it to us online.

Please include your account number in the subject line of all emails that you send us.

Providing email authorization

Your business is responsible for properly managing consent for us to share information with you. You must notify us of any change or cancellation to email authorization by sending us a message online, emailing us at, or calling 1-800-387-0750.

Only an authorized officer of the business (i.e., an individual within the company who would normally have access to, and control of, the information to be released) can provide email authorization (i.e., add, verify, change, or remove an email address) for the business.

Please refer to our authorization of employer representatives for employer accounts policy for more information.

Third-party representation or access

Businesses must complete the authorization for access to business account information form if they want to use a third-party representative for business account issues or provide company-related information to a third-party who does not legally represent them.

Emailing us about claims

You can submit claim-related forms, letters and more.

In some cases, we send emails to share claim information, with verbal consent. You won’t be able to reply to these messages, and they’re not encrypted unless you see “WSIB Secure” included in the subject. 

Knowing the risks

By consenting to email with us, you acknowledge and accept that there are risks associated with communicating by email. Transmitting information by unencrypted email has a number of risks that you should be aware of which include, but are not limited to:

  1. Email communications from the WSIB are not encrypted.
  2. Despite reasonable efforts to protect the privacy and security of electronic communication, it is not possible to completely secure information transmitted over public networks.
  3. Email can be circulated, forwarded and stored in numerous paper and electronic files.
  4. Use of email to discuss sensitive business information can increase the risk of such information being disclosed to third parties.
  5. Email can be misdirected, resulting in information being received by unintended and/or unknown recipients.
  6. Email is easier to falsify than handwritten or signed documents and it is impossible to verify the true identity of the sender, or to ensure that only the recipient can read the email once it has been sent.
  7. Email can be intercepted, altered, forwarded or used without authorization or detection.
  8. Email can be used to introduce viruses or other computer software code or routines designed to modify, erase, destroy, corrupt, disable, damage or impair other software or information into computer systems.
  9. Backup copies of email may exist even after the sender or the recipient has deleted his or her copy.
  10. Email can be used as evidence in court.

As a safety precaution, we recommend using software to check email for threats. We don't accept liability for any damage you may experience by viewing the content of emails.

Next steps

Once we receive the completed email consent form for business, or verbal authorization is provided from the owner of the business, we'll communicate via email with the authorized contact and email address as requested.
