A business or its representative can only obtain a copy of their employee’s claim file when they are objecting to a WSIB decision or if they choose to participate in an employee’s appeal.

According to the Workplace Safety and Insurance Act, 1997 (WSIA), both employees and their employer have an interest in an employee’s claim with similar rights to receive fair and equal treatment. When either one object to a decision, both employees and their employer can get a copy of the claim file documents to help them in the appeal process.

Before securely sharing any electronic claim documents with the employer, we notify the employee about their employer’s objection or participation in the employee’s objection and electronically share the documents we determine to be relevant. Employees are given an opportunity to object to the release of any health care information they feel is not relevant to the adjudication of their claim and are required to provide reasons for their objection. Visit our appeals page for more information.

Special rule for transfer of cost employers

If we find that a person’s injury or illness was caused by the negligence of another employee or business we may charge all or part of the claim costs to the employer.

If employer objects to a decision in your claim, access to relevant claim file information is given to employer to enable them to effectively participate in the decision-making process. The employer receives the same claim file access as described above, except you can object to the disclosure of any information in the claim file, not just health care information.

Receiving relevant claim information

Businesses or their representatives will receive an email with a secure link to access and download the claim documents. We will send the email to the business/business representative’s email address in our records.

To update the email address we have on file, complete and submit an email consent form or send us a message on our online services.

Under the Workplace Safety and Insurance Act, businesses and business representatives have a duty of confidentiality not to disclose any health information obtained from the WSIB about employees.
