The offering of suburban service to Montreal allowed new communities to spring up along the railway. Many were English-speaking immigrants working in the rail yards of Montreal who would commute into the city. Though many Anglophones left these neighbourhoods following the election of the Parti Québécois in 1976 and the referendum on sovereignty in 1980, their legacy can be found in the names of boroughs (Greenfield Park) and streets (i.a. Kensington, Cornwall, Glenn) that retain their British heritage.
