This number is used as part of the CRA scam that is going around.  A person leaves a message saying that you are violating tax laws and the police will arrest you immediately if you don't call that number back.  It is a SCAM.

cra scam, threatening to issue an arrest warrant.

Voice message claiming to be CRA threatening me with arrest if i don't call them back.

24 hours ago an unidentified caller left a threaten message on my answering service. Quote-unquote "If you don't call back we will have to issue an arrest warrant in your name!"  Since I am a law abiding citizen with no debts I immediately called my local police to make a report. I was told many others had been called from the same number with the same threat. Obviously a SCAM.
