"Sub-sub-series consists of C.I.9 certificates issued at Vancouver and Victoria, September 1910 to 1952. Earlier and later records either have not survived, or have not been transferred from the department. Certificates issued before September 1910 may have been handed over to the traveller, or may have been retained and destroyed in local offices. The certificates are organized by port, and are grouped in two groups for each port, one for persons born abroad and one for "native-born" persons. Each of these four groups is numbered separately, and is organized in numerical order, roughly by date of issue. Both redeemed and cancelled (expired) certificates are included. Some certificates are missing. Each certificate bears the following information: C.I.9 date and port of issue; details of planned travel, including place and date of sailing, trip name, port of destination and port of proposed return; personal information, including the holder's name, address in Canada, photograph, year of first arrival (if foreign-born), place of residence and year of first residence there, C.I.5 certificate number (if any) occupation, birthplace, age, height, and distinctive facial features; names and residence of two friends; holder's signature in Chinese characters; and data on holder's return, including (if returned) date and port of return, signature of inspecting officer, or date of letter of authorization; or (if failed to return) annotation indicating expiry of certificate.
