The Workers' Compensation Board's On-line Form Submissions are accessed through the Internet.  For security reasons, it is recommended that you do not access these forms through public internet access terminals (library, Internet cafe, etc.)

While we have tested these forms on a number of browsers, it is not possible to test for every possible configuration of software that may be installed on a user's machine.  If you encounter problems, please try closing down your browser, re-booting your machine and trying again.  If the problem persists, please refer to our list of Frequently Asked Questions.
