The Workplace Safety and Insurance Board (WSIB) is the workplace compensation board for provincially regulated workplaces in Ontario, Canada. As an agency of the Ontario government, the WSIB operates "at arm's length" from the Ministry of Labour, Training and Skills Development and is solely funded by employer premiums, administration fees, and investment revenue. The WSIB is one of the largest compensation boards in North America and is primarily responsible for administering and enforcing the Ontario Workplace Safety and Insurance Act (WSIA).
