Other related specialized case files are found elsewhere in the Immigration Program sous-fonds (MIKAN 322, RG76) and the Dept. of Citizenship and Immigration fonds (MIKAN 66, RG26). These can be divided into five groups: (1) pre-1946 special case files, (2) field office case files, (3) specialized case series, (4) appeal case files, and (5) Deputy Minister's Case files., 1. Pre-1946 Case Files were opened only in exceptional circumstances. These were most often cases involving deportations (e.g. for illegal entry or criminal activity), payment of indemnity bonds by immigrants sponsoring sick or handicapped relatives, child immigrants about whose treatment complaints were made to Immigration, and famous or notorious individuals. The few surviving files of this type are found scattered throughout RG76-B-1-a, except for the Chinese and Asian case files, which have been converted to special numbering systems (see surviving files in RG76-D-2-g and D-3-a)., 2. Field Office (Canada and Overseas Post) case files are regular case files opened at Immigration's field offices, including local, district, regional and overseas offices. Since the immigration process produces unique documents on individuals at many different levels (and not just at headquarters), records in these files may be entirely unique, or may partially duplicate records on the same individuals in an HQ case file. Some field office files are sent to Headquarters and are amalgamated into the main case file system. Examples of field office files are found in the Immigration field office series (RG76-E), most of which are in the RG76 accessions for the Halifax and Vancouver records centres. Some of these files were given "HQ" numbers, some placed under the "5113" Third Central Registry subject file block, and some in a numbering system parallel to the HQ series but prefaced with a local indicator, e.g. "P" or "PD" (Pacific District), or "ER" (Eastern Region) instead of "HQ". More recently the prefix consists of a numerical code corresponding to the individual office's "responsibility code". The case files created at overseas offices include both accepted and rejected applicants for immigration. Overseas records are sometimes grouped in batch files. Examples are found in accessions V-1985-86/472 and V-1985-86/477., 3. Specialized Case File Series, relate to specific kinds of cases. These include the SF case files containing classified correspondence (RG76-B-2); series relating to specific ethnic groups under special immigration restrictions, including the Chinese or CH files (RG76-D-2-g) and the "Asiatic" series (AN, H, J, T, and M prefixes, RG76-D-3); the assisted passage case file series with prefixes AP, W, and TL on travel and settlement grants to individuals (RG76-D-9); and possibly others., 4. Inquiry and Appeal files document individual applicants' appeals to various levels of the Department and to external tribunals, against decisions to refuse entry or sponsorship applications, to deport, or to withhold refugee status. These include records of individual inquiries at ports of entry (often not separated into files -- see RG76 accessions 1985-86/060 and 1985-86/085); adjudication case files (RG76, accessions V-1985-86/465, V-1985-86/479 and V-1985-86/480); departmental reference files for adjudicated cases appealed to the Immigration Appeal Board and the Federal Court of Canada (RG76 accessions V-1985-86/479 and V-1985-86/480); and possibly others. Related to these are the official case files of the external appeal courts themselves -- the Immigration Appeal Board fonds (RG82), the Federal Court of Canada (not yet transferred to the National Archives), and the Supreme Court of Canada fonds (RG125)., 5. The Deputy Minister's Records for the period 1949-1966 include case files in block 3-10 for a few especially controversial cases, dated 1932-1967 (RG26-A-1-c, Vols. 172-173).
