The guy has East Indian accent. Was pretending to be a CRA representative.
Was threatening to file a criminal case within 24 hours. Was asking for my lawyer info.

I got the same scan from the same guy. He told me my wife owed over $6000 to the CRA and they considered the matter willful and criminal. If the matter went to the courts it could cost us over $40,000 and she could go to prison for up to 2 years. He then asked how I would like to proceed. He gave me the option of handling it now or going to court. I told him this sounded like extortion and fraud and he hung up on me.

This is not REAL! If you CRA suspects you of tax fraud the first you hear of it will not be a telephone call giving you 24 hours before a warrant will be issued for your arrest.

I had a call from the same person.  Mine was a message left identifying himself as an officer and that a legal claim was filed against me.  He said he was from the CRA.  Just another scam.

Some "Officer Walter" left a message pretending to be calling about a legal case filed against my husband by the CRA. I felt it was sketchy, so I googled the number. My suspicion was confirmed here.

Got a call from this guy. Said his name was Mike Wallace. Said that he was from the criminal arm of CRA and asked me if I had a lawyer. He said criminal case will be filed tomorrow at which point I will have no recourse but go to jail for 3 years and will cost me 50K and impact my credit history and might even cause me to lose my job and citizenship.

When I pushed him for details, I knew he was a scam artist. I asked him to provide me his office no so I can call back and he said this was my last chance. I said please proceed as I need it in writing or proof of his identity to talk further.
