This is the biggest scam in the U.S. and Canada. The scammers say you owe money on back taxes and if you don't pay you will be arrested etc etc. They say if you settle over the phone at a discounted amount they can make the charges disappear.This is the potted version, at the end of the day the taxman never cold calls you but sends certified mail if they need to. Check out the CRA website for a fuller explanation. It is a scam.
So can someone on this site describe what the scam is and what these people are trying to achieve? Are they just causing mischief or are they trying to get money from us old folks.
