Like other recent immigrants to Canada, Black Canadian immigrants have settled preferentially in provinces matching the language of their country of origin. Thus, in 2001, 90 per cent of Canadians of Haitian origin lived in Quebec, while 85 per cent of Canadians of Jamaican origin lived in Ontario. A major change in the settlement patterns of black Canadians occurred in the second half of the 20th century as the mostly rural black Canadian communities had become mostly urban communities, a process starting in the 1930s that was complete by the 1970s. Immigrants from the West Indies almost always settled in the cities, and the Canadian historian James Walker called the black Canadian community one of the "most urbanized of all Canada's ethnic groups".
