A wave of immigration occurred in the 1920s, with Black people from the Caribbean coming to work in the steel mills of Cape Breton, replacing those who had come from Alabama in 1899. Many of Canada's railway porters were recruited from the U.S., with many coming from the South, New York City, and Washington, D.C. They settled mainly in the major cities of Montreal, Toronto, Winnipeg and Vancouver, which had major rail connections. The railroads were considered to have good positions, with steady work and a chance to travel. A noted cause célèbre in the 1920s was the case of Matthew Bullock. He fled to Canada to avoid a potential lynching in North Carolina and fought extradition to the US.
