 The MUC Transportation Commission was thus created at the same time to serve as prime contractor for the Metro extensions.It merged all island transport companies and became the Société de transport de la communauté urbaine de Montréal (STCUM) in 1985 and then the Société de transport de Montréal (STM) in 2002.The success of the Metro increased the pressure to extend the network to other populated areas, including the suburbs on the Island of Montreal.
