Deux-Montagnes

The name "Deux-Montagnes" (French for "Two Mountains") dates to 1674 when it was given to the lake bordering on the municipality, and to the seigneury which stood north of the lake. Founded as the Village Municipality of Saint-Eustache-sur-le-Lac in 1921, it became a city in 1958, and changed its name to Deux-Montagnes in 1963.

Ten thousand years ago at the end of the pleistocene, the Champlain Sea covered a large part of southern Quebec and left behind the clay, sand and peat soil that is now under the city of Deux-Montagnes. When the sea retreated to the Atlantic Ocean, along the channel that is now the St-Lawrence River and its tributaries, the Rivière-des-Milles-Iles and the Lake of Two-Mountains, southern Quebec became a favourable area for hunting and gathering.

In 1930 a new chapel was built in response to a request from parishioners of St-Eustache-sur-le-lac, where Monseigneur George Gauthier, Archbishop of Montreal gave permission to replace the small Bélair chapel, that was "located on the Chemin du Grand-Moulin at the foot of De La Chapelle street, on the banks of the Rivière des Mille Îles"(Plante, p. 174). The Parish of Saint-Agapit was officially founded on July 7, 1946. On April 12, 1961 a violent explosion occurred in the basement of the church while 150 children were inside. The children all ran out, and only the chimney remained from this incident. On August 28, 1962 the new Saint-Agapit Church was officially inaugurated after parishioners carried numerous fundraisers to rebuild their church. (Plante p. 174-176)

Most Reverend Emilien Frenette, who was then Bishop of Saint-Jerome, founded the Holy Family Parish on December 26, 1957. This parish served and continues to serve the English Catholic community of Deux-Montagnes. (Plante p. 178)

The history of the United Church of Canada began in the early 1800s. By 1838, the English community of Protestants of St-Eustache built a church where its members attended until 1926. This community attended their first meeting on August 19, 1927, "in the new church built by volunteers on the corner of 8th and Cedar avenues" (Plante p. 179). The first pastor of the Community Church of the United Church of Canada, Stan Kennedy was welcomed on July 1, 1953. During his charge, he decided to sell the church built in 1927. The new church was built on 14th avenue, across from the original Lake of Two-Mountains High School, on July 30, 1955. (Plante p. 180)

The Evangelical People’s Church, was built and founded on 5th avenue in April 1964. (Plante p. 181)

In 1946 at the "little yellow schoolhouse", a dozen faithful Anglicans met in a classroom and began the history of the Anglican community in Deux-Montagnes. Because of the demand for a bigger space, the congregation moved to a mansion on the corner of 11th avenue and Boulevard du Lac, and renovated and enlarged the premises. The church moved to a bigger location in 1955, on 18th avenue. (Plante p. 182)

In 1946, when the parish of St-Agapit was established, Father Chartrand, the parish’s first curate donated his selection of books to start a public library. These books were located in the rectory and then moved to the church basement. The books were eventually transferred to the local Club Femina where Annette Magnan offered many services in the St-Eustache-sur-le-lac library until her death in 1975. The books were sold and the Club Femina moved to other premises. A group of citizens formed a committee in order to create a public library and the city adopted a by-law establishing the Municipal Library of Deux-Montagnes on January 12, 1978. The new books bought by the city council, were moved to the new premises in the community center on March 1, 1978. Internet access was introduced in the library in 1997 to further modernize the premises.

The municipality has two Réseau express métropolitain (REM) stations: Deux-Montagnes and Grand-Moulin. Both stations were formerly commuter train stations on the Deux-Montagnes line and were rebuilt between 2020 and 2025, reopening for REM use on November 17, 2025.

The Commission scolaire de la Seigneurie-des-Mille-Îles (CSSMI) operates Francophone schools. The Sir Wilfrid Laurier School Board (SWLSB) operates Anglophone schools. The little yellow schoolhouse, located at the corner of 14th avenue and Chemin d’Oka, was the only educational institution during the 1940s. At the time, English and French students were accepted. A teacher earned $300 annually and was provided lodging on the second floor. The school was shut down in the 1960s because of a population increase in the area and the new construction of St-Jude School. (Plante p. 182)

• Lake Of Two Mountains High School (LTM) The original Lake of Two Mountains High School was at the corner of 14th avenue and Chemin d’Oka where its first class graduated in 1954. A new building was built in 1981 on Guy street and still stands here today. The Lake of Two Mountains High School serves students from neighbouring towns including Deux-Montagnes, Kanesatake, Mirabel (St-Augustin Sector and St-Benoit sector), Oka, Pointe-Calumet, St-Joseph-du-Lac St-Eustache, St-Placide and St-Marthe-sur-le-lac. • St. Jude Elementary School In 1949 Saint-Jude Elementary School was built on Saint-Jude Street, behind the Saint-Agapit Church because the town was experiencing a population boom. In 1953, the school reached its total capacity of students and resulted in the building of the Sauvé School. (Plante p. 183) • Mountainview Elementary School Built in the early 1960s on the corner of Guy Street and 20th Avenue, St-Eustache sur-le-Lac Elementary School (as it was originally called) served the English-speaking, non-catholic (i.e.Protestant) community, before the implementation of the non-denominational school board system throughout Quebec. The school still operates today, as Mountainview Elementary, as part of the Sir-Wilfrid-Laurier School Board. (S. Menard, alumni).

• École Sauvé Sauvé Elementary School, opened in 1953, and taught children from grades 1 to 9. In 1957 a second floor was added to the building because of the growing number of children in St-Eustache-sur-le-Lac. In the 1959-60 school year, French primary students were taught on the first floor and English primary students were taught on the second floor. Because of the ongoing population growth, it was decided in 1961 that all French students would attend Sauvé School and all English Students would attend Saint-Jude School.
