Scope and content

Sub-series consists of records from the registry system known as the Third Central Registry system (5000 block). The records contains the core subject files of Immigration headquarters in Ottawa that were active between 1966 and about 1977. This records system superseded the second Central Registry system (500 block) on April 1, 1966 and was replaced by the fourth Central Registry system (8000 block) in about 1977, although material continued to be added to the old files until 1979. The 5000 block thus contains records on most of the activities of the Immigration Division of the Department of Manpower and Immigration, from the time it was established in 1966 up to its replacement by the Immigration and Demographic Policy Group of the new Canada Employment and Immigration Commission in 1976-1977. There are also a few records of earlier date from previous filing systems, especially the second Central Registry (500 block). The subjects covered are similar to those in the previous Second Central Registry system. They include immigration law, policy and procedures both generally and in specific fields; the organization and administration of the Division, its Canadian field offices, and to a limited extent its overseas posts; liaison with other federal and provincial government offices, foreign governments, and private organizations; reference files on immigration history and statistics; and a variety of related matters. No individual case files are included in the Headquarters 5000 block files (although similar series created in Canadian field offices do contain case records). Many of the subject files do, however, contain incidental documentation on specific cases. Files in the 5000 series are numbered in a "duplex-numeric" system involving both subject and geographical codes. The primary number is a general subject code in the range 5000-5999. The secondary number denotes a more specific sub-heading. The tertiary and lower numbers (if any) represent either a further subject breakdown or a specific geographical location, organization, or some other individual entity. Many of the blocks include long subseries documenting activities at particular foreign posts or nations; their subnumbers are usually assigned alphabetically by name of post city or country. The 5000 block proper is divided into two parts for security reasons: the Unclassified files sub-sub-series (RG76-B-1-c-i) and the Classified files sub-sub-series (RG76-B-1-c-ii). The files or file parts containing material classified above "confidential", were segregated by the Department for separate storage. Different parts of the same file may be separated if some contain classified records and some do not. Thus researchers should check both sub-sub-series for all file parts of a given file.

Three other Immigration NHQ file systems containing general subject records were active at the same time as the 5000 block: the SF sub-series, the FS 5000 series, and the Immigration Intelligence series.

The SF ("Secret File") sub-series (RG76-B-2) contains another portion of the Immigration Division's subject correspondence classified above "confidential", which was for security reasons maintained separately from the main 5000 block. Some time after the creation of the SF sub-series -- possibly not until the mid-1970s -- the records office began to place secret material directly into files of the 5000 block. Thereafter a certain number of SF files were actually merged into the 5000 block to form the "classified" 5000 files (RG76-B-1-c-ii). The SF series continued to exist in parallel to these files.

The FS 5000 series contained files of documents (both originals and copies) removed from the main 5000 block registry in early 1971 by the Department's Foreign Service Division (FSD). These records were placed in a separate registry to document the Division's administration of overseas immigration operations. These records also deal to a considerable extent with departmental policy and procedures generally in the period 1971-1983. In addition to the files removed to the FSD, duplicates were created of a number of files remaining in the main registry; some entirely new files were also set up.

The FS 5000 files were transferred as a body to the Department of External Affairs in 1981 when that department took over Immigration's foreign service component. They were closed out on January 1, 1983 and replaced by External Affairs' "85" block. When transferred to the National Archives these files will be placed in the Department of External Affairs fonds (RG25, MIKAN 49).

The Immigration Intelligence records relate to security and intelligence matters as they affect immigration. See the Immigration Intelligence Division series (MIKAN 134899, RG76-D-7) for further information.
