I received a voicemail from Officer Michael Smith saying that I have a criminal case filed by CRA . I phoned the number and it's Officer Jim Arthur from CRA telling me that I owed from CRA for my tax in 2006-2013 and that an arrest warrant is already being issued...he was even mad when I asked why. what a scam...

John Adams is who the man called himself said the CRA had an arrest out for my husband.
These guys really think that we are dumb.

John or John Quincy?   You must be important folks, some other people only get movie stars, and some of those are washed up.  The Adams boys are way cooler.  If you are in Canada, resurrected US Presidents collecting your debt is quite an honor!  It's possible that you had John Adams, the composer.  That is not a good as a President, but if you like Philip Glass or Brian Eno, you might want ask for a signed CD.

Same here .. I got a call from Bryan Joy(ce) , leaving the message that I was selected ( or whatever ) by CRA as I have made a criminal offence with my taxes  and if I don't call ASAP that arrest warrant will be issued..   Boy, was I surprised :)
message left was barely understandable, as " bryan' could barely speak English; I would assume that CRA wants to save money by outsourcing customer service to whatever African/Indian country..  anyways..  scam .. good thing is that above mentioned number is always busy , so hopefully no astronomical charges for calling ..   Great job with this site !!

I would check if there is a scam with calling that number as there is a possibility that you might be charged astronomical fee for a phone call.  Check with your phone company though
