Rapport Annuel 1997. (p.51). https://www.stm.info/sites/default/files/pdf/fr/CA/archivesRA/rapport_annuel_1997.pdf by the Société de Transport de la Communauté Urbaine de Montreal (STCUM). They were built in 1994–1995 by Bombardier Transportation at its La Pocatière factory. They were delivered to the STCUM at a final cost of $119,5 million. They first operated for the STCUM starting October 26, 1995 until January 1, 1997 when operation were transferred the newly created Agence de transport métropolitaine (AMT) which had gained ownership of the rolling stock earlier on December 20, 1996. On June 1, 2017 the AMT's operations was reorganized into the Réseau de transport métropolitain (exo) which became the owner and the operator of the trains.
With the closure of the Deux-Montagnes line on December 31, 2020, in favour of the Réseau express métropolitain project, the MR-90 fleet was withdrawn from service. They were subsequently transported to Exo's Pointe-Saint-Charles maintenance center for storage. A request for information has been issued to determine the fate of the cars. In 2022, exo announced that the MR-90 coaches would be scrapped. A single married pair, composed of motor car number 400 and trailer with cab number 485, was set aside for preservation at the Canadian Railway Museum in Saint-Constant.
