Beginning in 1908, entry ports were set up along the border in established towns and villages, and records were beginning to be kept. Please remember that there are no records for people whose parents were either born in Canada or had previously resided in Canada - they were considered to be "returning Canadians".
The entry form used was called Form 30 (as opposed to Form 30A, which were Ocean Arrivals), and it was used from 1919 to 1924 for each person crossing the border.
There is one reel of microfilm for people who were rejected entry into Canada: Reel T-15345.
Form 30 was discontinued in 1935, and the large passenger form was reinstated.
Usually the following information was filled out in them -
- Port and Date of Entry
- Last Permanent Address
