St. Albans Lists: US Ports of Entry in Canada
Taken from the U.S. Citizenship and Immigration Services website:
"Under a US-Canadian agreement signed in 1894, immigrants destined to the United States were inspected and recorded by US immigrant inspectors at Canadian ports of entry. Ship passenger manifests listing those passengers stating their destination as the United States were filed in the INS Canadian Border District headquarters in Montreal, later moved to St. Albans, Vermont."
Access to these lists and their Soundex Index is available on microfilm via NARA: US National Archives and Records Administration for a fee.
