WSIB/CRA information sharing agreement

The agreement

The Canada Revenue Agency (CRA) and the WSIB signed a Memorandum of Understanding agreement in 2004. This formal agreement allows both organizations to share information for the purposes of enforcing or administering their respective programs.

The agreement sets out the rules, protected by strict privacy and confidentiality guidelines, which allow the WSIB to exchange information with the CRA. This information can only be used to ensure employers and workers are in compliance with the Workplace Safety & Insurance Act (WSIA).

The exchange of information is used to ensure the WSIB and CRA are creating a level playing field for all employers and workers in Ontario. Achieving a level playing field and fairness means making sure all workplace parties are compliant with the respective federal and provincial regulations.

Legal Authorization

Section 241(4)(n) of the Income Tax Act authorizes the CRA to provide tax payer information to any workers’ compensation board in Canada for the purpose of the “administration or enforcement” of each province’s  and territory’s compensation legislation.

Canada Revenue Agency (CRA) collects information from the Government of Ontario, Workplace Safety and Insurance Board, in accordance with the Income Tax Act and Part IX of the Excise Tax Act for administration and enforcement of tax legislation. A full list of uses and disclosures of personal information are described in Personal Information Banks (PIBs) in the CRA Chapter of the Info Source publication. Under the federal Privacy Act, individuals have a right of access to, correction of, and protection of their personal information. Learn how the CRA protects personal information and your rights under the federal Privacy Act.

Section 159(9) of WSIA enables the WSIB to enter into agreements with the Government of Canada. Subsequently, the WSIB and CRA established a formal Memorandum of Understanding agreement.
