From World War II to 1991, most Ukrainians coming to Canada were political refugees and Displaced Persons who tended to move to cities in southern Ontario, southern Quebec and the Lower Mainland of British Columbia – there are now large Ukrainian communities in Toronto, Montreal and Vancouver. They established a number of new organizations and affiliated newspapers, women's and youth groups, the most prominent of which was the Canadian League for the Liberation of Ukraine (renamed the League of Ukrainian Canadians after the collapse of the USSR in 1991). The League joined the Ukrainian Canadian Committee (later Ukrainian Canadian Congress) as a member organization in 1959.
