Mr. Speaker, the Canada Revenue Agency takes the protection of taxpayer information very seriously. The CRA has robust safeguards in place to identify fraudulent emergency and recovery claims. Canadians who receive a T4A for CERB payments they did not claim should contact the CRA as soon as possible. Victims of fraud will not be held responsible for any money paid out to scammers using their identity.
