This is the online gateway to the massive archival collections of the Canadian Federal government. Many dozens of databases, called “Research Tools,” are provided. For example one tool is Immigration Records (1925-1935). Here is listed, among others, the names of all the Russian Mennonite immigrates fleeing the Soviet Union that came to Canada in that decade. Another tool is titled: Post Offices and Postmasters and here one may find the names of any person who served as a postmaster and dates and place of service. This site is a wonderful source of very diverse information.
