Sounded like someone impersonating Canada revenue asking you to return their call.
At the end of the message they advised good luck with your legal expenses.
Just picked up two voice mails today from my home phone. Both calls are scams. Worked for CRA for very long time and this is not how they deal with you. Don't answer these calls or call back.
This caller identified himself as a Canada Revenue Agent....obviously a SCAM to get your money....DO NOT CALL HIM BACK. I wish the Police would put scammers like this out of business for good! - Niagara Falls, ON
Received 2 calls from 647-946-6431 today claiming to be CRA. Just hung up both times. I agree wish someone would do something about these type of people.
