partial answering machine message from "Revenue Canada" threatening an arrest warrent

Revenue canada threatening arrest warrant

CRA Threatening arest warrent.

Says I owe Revenue Canada and an arrest warrant will be issued. I pressed caller for details and he advised the process is done and this was my final warning and hung up.  I called back to a busy line.  I have never receive any notice from CRA otherwise.   I called CRA and the rep identified her self with a long ID number.  The caller says he's Brian?   SCAM !

I have received the same call two times threatening an arrest warrant and civil claim. It is a scam - see the CRA's website: http://www.cra-arc.gc.ca/menu-eng.html for a warning. Report it to the CRTC.
