Fonds contains the records of the Toronto Office (Central region) of the Jewish Immigrant Aid Services of Canada. The fonds consists primarily of textual records: minutes, correspondence, financial records, reports, immigration files, naturalization case files, social service case files and the records of attempts to trace missing individuals. There are also photographs of special events, speakers and arriving immigrants.

The fonds represents an important resource for the study of Canadian Jewry, especially when taken in conjunction with the JIAS National Office records at the Canadian Jewish Congress National Archives in Montreal, and those of the Western Office at the Library and Archives of Canada. It documents the means by which a particular Canadian ethnic community has dealt with the problems of rescue, settlement and government relations. These records also offer insight into the relationship between the Toronto Office and the other branches of JIAS, and invite comparison with similar agencies in the United States, as well as those of other ethnic groups in Canada.

The material collected includes information about the countries of origin, transportation routes, settlement and employment patterns of Jewish immigrants to Canada in the twentieth century. The documents also touch upon important related issues such as advocacy, sponsorship, admission processes, health and social problems.

These records cover several waves of immigration following the Second World War: Holocaust survivors in the late 1940s, Sephardic (North African) and Hungarian Jews in the 1950s, Russian and Czechoslovakian Jews in the 1960s, and additional Russians in the 1970s.

The records also contain significant information for those researchers looking to conduct genealogical research into Jewish immigrants and their descendants.
