automated message left on voicemail claiming to be Revenue Canada, arrest warrant issued, and to call them back for information - it is a scam, do not call the number back. Have received a lot of calls claiming the same thing from many different numbers, they are all scams fishing for information.
This number called and left an automated voice mail stating that an arrest warrant had been issued but with no details, no identification on who called, who the warrant was for or for what, but urging you to call back that number if you wanted further details.
