A Canadian Committee of the JCA was established in November 1906 to assist in the settlement of thousands of Jewish refugees fleeing Russia, and to oversee the development of all JCA settlements in the country.
Rosetown (1911) near the eponymous town in Saskatchewan.
The JCA also established two agricultural colonies in the first two decades of the 20th century in what now is Turkey. In 1891, JCA bought land near Izmir in Turkey and established an agricultural training centre, or Yehudah, on an area totaling 30 km² by 1902. The center was closed in 1926 owing to numerous difficulties. A group of Romanian Jews in Anatolia were assisted by JCA in the early 20th century to establish an immigration bureau in Istanbul in 1910. The JCA also bought land in the Asian part of Istanbul and founded Mesillah Hadassah agricultural colony for several hundred families. In 1928 the colonies were mostly liquidated, with only the immigration bureau remaining to assist migrants in their migration to Palestine (see also:PICA).
Economic factors, notably the Great Depression, led to the dissolution of all western Canadian colonies by the end of World War II. Thereafter concentrating its work in the east, the Canadian chapter of the JCA purchased farms and made loans to farmers in Ontario and Quebec:
The JCA Canadian Committee made no loans after 1970 and ceased all legal existence in 1978. The JCA deposited the majority of its papers at the National Archives of the Canadian Jewish Congress in 1978, and the remainder (the "S" collection) there in 1989.
