Just received a call from this number claiming to be from CRA, called it back and they just ask for a a Mr or Mswhatever last name your phone number is registered in (depending on if you are male or female answering the phone), . They asked how to pronounce my first name, Michelle is a pretty common name and not hard to say. I told them I wasn't comfortable giving out my name, and said they can try to pronounce it or just call me by my last name and they hung up.
A very garbled recording of a female voice, stating that an arrest warrant has been issued, with a long, unintelligible reference number, and telling you to contact "Officer Allan White".
From the previously-posted comments, and the very amateur recorded message, it appears to be a scammer.
Called back to the calling number, and got a recorded message, a male voice, foreign accent, with noise of children playing in background, another garbled message, asking you to leave a message and he'll text you back.
