The Canaryville neighborhood is one of the oldest neighborhoods in Chicago and, with neighboring Bridgeport, has a reputation for insularity or hostility to outsiders. According to the "Encyclopedia of Chicago", the neighborhood extends from 40th Street to 49th Street between Halsted Street and Parnell Avenue. The area's residents depended on the development, and suffered from the decline, of the livestock and meat packing industries. Its more successful members moved to newer housing, often in the suburbs, and other work in the post–World War II years.
