The borough is located at the eastern tip of the
Island of Montreal. It is composed of the districts of
Rivière-des-Prairies,
Pointe-aux-Trembles and
La Pointe-aux-Prairies, which were part of the City of Montreal prior to the 2002
municipal mergers. Prior to 2002, it was an
exclave separated from the rest of Montreal by independent cities to the west. From January 1, 2002, to January 1, 2006, the borough included the town of
Montreal East, which has now demerged from Montreal. The borough's name lists the two neighbourhoods according to their date of annexation to Montreal (Rivière-des-Prairies joined in 1963 and Pointe-aux-Trembles in 1982). It has a population of 107,941. Rivière-des-Prairies is mainly composed of suburbs, as well as multiple forested areas and fields. Pointe-aux-Trembles is more urban and dense but remains suburban in nature. The third district, La Pointe-aux-Prairies, is a typical suburb composed of townhouses, condos and single-family dwellings, which makes it a destination of choice for young families that wish to remain on the island of Montréal. The
Saint Lawrence River flows at the southern border of Montreal, while the
Rivière des Prairies River forms Montreal Island's northern boundary with Laval. ==Demographics==
