same thing...called me 4 times today.  don't give them any information.  If they say the cops are showing up in 45 minutes (gotta be a record for tax evasion.)....say something dirty and witty (  try to be clever :) ) and hang up on him.  Piece of garbage.  Call the cops and they'll most likely direct you to the anti fraud center.

Voicemail from a woman with a very bad / fake New York accent claiming 'There is a criminal case against you for tax evasion and tax fraud' etc etc, and advising me of the seriousness of the charge. Claimed if I didn't call back a serious case would proceed against me and I would be served by the county sheriff later today. Referred to the callback number (613) 604-9949 as that of 'CRA Headquarters'. [Like, really?]Needless to say I didn't call back but started googling CRA phone scams!

Caller called twice.  Claimed to be from CRA.  I suggested the call was suspect and would call them back.  I did not.

Agressive male voice telling he's from canada revenu agency(cra)accusing us of taxe fraud, asking to call (613) 604-9949 ASAP or we are going to deal with police today !!!

I was at my boyfriends place today he got this call! Claiming the sheriff would be dropping by to serve notice.

Just got a nasty female machine message. Very disturbing. Have the rest of you had previous problems with CRA? Wonder how our phone # got picked.
