This has been going on for years, but my wife received a call last night that went to voice mail from someone claiming to be from the CRA saying that we owed them $3000.

She called the number back that they gave her (1-855-487-8483), and the person on the other end was continually insisting that she needed to pay this money, at one point saying that they would be sending the RCMP to our house to arrest her in the next half hour.

This is obviously not the CRA and if you search the phone number online you will see they have been doing this all over north America for a long time.

Don't forget, the CRA have all your financial information, if someone is demanding your SIN or something like that demand that they tell you what your income was last year, or 2 years ago. If they can't answer, they are NOT from the CRA. As well the CRA will send several notices by mail, culminating to a registered letter before they will ever threaten legal action or call you on the phone for immediate payment.
