The second largest urban area in Canada is the Montreal Region, with a population of 3.6 million people. It is surpassed in size only by the Greater Toronto Area. In 2002, two of the former counties underwent significant municipal restructuring, the Montreal Urban Community becoming the new City of Montreal, and the MRC de Champlain becoming the new City of Longueuil. Transit service in and around Montreal is provided by the Agence Métropolitaine de Transport, or AMT, which is made up of nearly twenty separate transit systems: service in Montreal is provided by the STM; in Laval, by the STL; and in Longueuil, by the RTL. There are also more than a dozen smaller systems providing service to towns on the outskirts, as well as at least one independent transit agency, and a commuter train system operating as far as Hudson, McMasterville and St-Jérôme.
