It is difficult to furnish a definite figure, as the number fluctuates continuously. Upon evidence being received indicating that the mails are being used for the transmission of illegal matter, mailing facilities are withdrawn from the person or organization concerned. When this action is taken the illegal enterprise is either abandoned, or discontinued in so far as the use of the mails is concerned, or an endeavour is made to circumvent the post office action by use of different or fictitious names. As the new names and addresses connected with illegal uses of the mails are ascertained mailing facilities are withdrawn.
During the twelve months ending May 31, 1938, instructions were issued withdrawing mailing privileges in Canada from approximately 1,450 persons and 50 organizations. During the same period mailing facilities were restored in about 150 cases.
