Passenger lists are one of the most important items you will want to search when looking for your ancestors.
FamilySearch continues to add more records to their collection of Canada passenger lists. These lists cover the period from 1881 to 1922 and the latest additions add a further 33,000 records to the collection.
This collection can be searched by first name and last name. Alternatively, you can browse through the 145,000 images in the collection, which are organized by port of arrival and month/year. Access is free. The link to the entry page for researching passenger lists at Family Search is Historic Canada Passenger Lists
