The information sharing for social benefit program integrity is criteria-based. Information with respect to individuals who meet specific criteria would be shared systematically with Employment and Social Development or the Canada Revenue Agency. If those individuals are collecting benefits erroneously, they would then undertake their program integrity investigations in order to cease those payments and recoup any overpayments. For example, OAS is for people over the age of 60. We wouldn't be sharing information on a 25-year-old for OAS purposes.
