I intercepted that call as it came into my father's house.  It is a scam.  Apparently he is being audited by the CRA and he is being charged for tax evasion.  LOL... Ok so first off the "officer" would not talk to my father's accountant and then I think he almost fainted when I got assertive with him and told him that I wanted to know the SIN number on file and my father's middle name.  I called the OPP and was directed to the Fraud Centre to report this.  Do Not give them any information.
