Caller called and said he's from Revenue Canada - we disconnected, because it sounded like a scam. When we called back this number, the person who picked up, said "Crimes and Fraud Investigation Canada." To my knowledge, there is no such entity.
Some weirdly-accented [***] left a message claiming to be "Officer John Parker" threatened me over a "time-sensitive" issue, where I, or my attorney should call him back immediately, otherwise he wished me "good luck". What a douche. Probably a tax scam. There must be a special circle of hell reserved for these pricks.
My mom also got call from CRA. John. left on answering machine. He said something about attorney and needed us to call back as it is time sensitive. Didn't bother after finding this already being reported here.
