Saying its Revenue Canada and if I dont my call SIN number will be flagged?  Scam if I've ever heard one.  Revenue Canada doesnt make phone calls and the "robot" voicemail was a person by the name of Officer Wrangler Johnson. :)

the call says something about me being sued because I owe Revenue Canada money.I know this is a scam as I phoned Revenue Canada and of course they say I owe them nothing and this is a scam.
