Form 30 Border Crossings 1919-1924

Are you struggling to find an ancestor arriving in Canada in the early 1900s?

Between 1919 and 1924, the individual Form 30A was used instead of the passenger list. The use of this form was inconsistent; if you do not find a reference to an immigrant for that time period, Library and Archives Canada (LAC) recommends that you search the passenger lists for those years.

According to LAC "The records were microfilmed in quasi-alphabetical order and the digitized images for Forms 30A (Archived) can be searched in that order in Digitized Microforms (Archived).
