The Leads Program does not accept information by email or in person.
The mailing address and fax line are for suspected cases of tax or benefit cheating only. Information sent to the National Leads Centre that is not clearly intended for the Leads Program will not be redirected to other CRA programs or outside organizations, because of the sensitive nature of the correspondence.
