Just received  an obviously scam call (recorded message although I answered the call) purporting to be an 'Officer John Barker', or possibly Parker, of the CRA.  Left the above phone number, said it was regarding a serious legal matter and threatened severe legal action unless the call was returned within 24 hours.   Since of course I did not and will not call the number I can't comment on the nature of the scam but urge extreme caution if you receive a similar call.

Received this scam call on March 18. Officer John Barker threatening legal action.  Same as other commentators, with this 705 number and others.
