This is a scam.  It is a recording from the supposed CRA using a police Constables name.  The CRA does NOT use police to contact a person.  It is done with a real person and they usually do not leave a message.  DO NOT Answer and if it is this recording, hang up and do not call back.

Actually, if the CRA is anything like the IRS, I doubt they call at all and would ACTUALLY send you a certified letter with return receipt via the Postal Service

A had a recorded call from this number whith the usual bla, bla about a criminal lawsuit from CRA. I get this kind of call every week,  from different phone numbers.  It looks like it is a very good business for scamers. Why people are still believing  this is legit?
