It has a ticket barrier at transept level leading to a single entrance adjacent to a bus loop and a municipal parking lot. This station is named for boulevard Rosemont,
Montreal Metro station in 1981. As the stations were completed, the service was extended. In December 1979 Quebec presented its "integrated transport plan" in which Line 2 (Orange Line) was to be tunnelled to Du College station and Line 5 (Blue Line) from Snowdon station to Anjou station. The plan proposed no other underground lines as the government preferred the option of converting existing railway lines to overground Metro ones. The mayors of the MUC, initially reluctant, accepted this plan when Quebec promised in February 1981 to finance future extensions fully. The moratorium was then modestly lifted on Line 2 (Orange Line)
