Sub-sub-series consists of individual entry records for the period 1919 to 1924. Starting 1 January 1919, the Department of Immigration and Colonization required that individual entry records (Form 30) be completed and submitted at the border ports of entry, rather than by using the old, larger sheet lists. A form had to be submitted for each individual, including children; however, the names of accompanying dependents were sometimes listed on the back of the head-of-the-household's form. Form 30 contained the following details: port and date of entry, name, age, occupation, birthplace, race, citizenship, religion, previous residence in Canada, destination, and nearest relative in the immigrant's country of birth or citizenship. The use of Form 30 was discontinued as of 1 January 1925. From that date, the use of large sheet entry forms was reinstated.
The forms were microfilmed in quasi-alphabetical order. For each letter of the alphabet, surnames are arranged in groupings based on the initial letters of each name. For example, surnames starting with Ada, Adc, and Add are interfiled starting with given names beginning with A. Such grouping could include the following arrangement of forms: Anne Adair, Benjamin Adcock, Christopher Addison, David Adair, etc. Another example would be: Adam Downey, Bertha Dow, Claire Dowd, Edward Downs, etc. Some of the more common surnames, such as Smith, Adams, MacLeod, are grouped separately. Note that each form was microfilmed with the back side first, followed by the front page of the form. The forms completed by admitted immigrants comprise 96 reels. Only one reel of forms for those rejected at the border has been retained (T-15345).
