The manifests of ships arriving at Canadian Ports listing passengers have been preserved on microfilm at Library and Archives Canada. The goal of the Nanaimo Family History Society is to index arrivals at Halifax and Quebec (Montreal is included in the Port of Quebec) from 1900 to about 1921 when the passenger lists were discontinued for a time in favor of the form 30A.
Quebec Ports for the periods 2 Jul 1908 to 13 Oct 1910 has been completed and the index, made up of 284,365 listings from 586 ship arrivals, is shown at their website. The pages of the index are PDFs with a comprehensive “Names Starting With” page that allows quick access to all portions of the index.
