Definitely a SCAM!  Don't give him any information.  Report him!

Watch out  for this scam ,person says he calls from cra.

They are fraud people they call u to tell u tht u owe cra some money when in reality you dont. Just swear at them or diconnect or go with the flow its fun

I also got a message in my voice mail . Telling me someone stole my identity and I should call (647) 495-9411 if I do not call they will arrest me they are calling from Ontario Police etc etc etc .

I got a call from this number from a man  claiming to be officer shawn woods .(He happened to have a strong Indian accent ) instructing us to get in touch with him as he has a arrest warrant for my husband . If we didn't get in touch with him we would be  in serious trouble .So I got in touch with the real Shawn woods from the CRA who confirmed that it was not him calling (He was definitely not of Indian  origin by his accent ) and  stated this is a prank  someone is playing.  

I did too and I am worried
