 After the war, Borden banned Mennonites and other pacifists from immigrating to Canada for three years from 1919 to 1922.At the same time, there was the out-migration of the more conservative Mennonites, who left the area for Mexico and Paraguay, after the Canadian government required them to learn English and attend public schools, issues which seemed to be in violation of the Privilegium signed in 1873.After the Mennonite immigration ban was lifted in 1922 by Liberal Prime Minister William Lyon Mackenzie King, a second wave of Mennonite immigration occurred due to the Russian Revolution, and many of the "Russlander" Mennonites took over farms and land left unoccupied by the Mennonites leaving for Latin America.
