The "rivière à l’Orme" originates in the southwestern part of the Pierrefonds borough of Montréal, on the west side of the Cineplex Kirkland Theater.

From its source, the "rivière à l’Orme" flows over 5.1 kilometres (3.2 mi) according to the following segments:

  • 1.5 kilometres (0.93 mi) southwesterly along the north side of autoroute 40 and cutting off the Timberlea Trail up to an urban stream (coming from South of autoroute 40);
  • 3.6 kilometres (2.2 mi) northwesterly up to its mouth. Note: the “Anse à l'Orme road” runs along this segment, first on the North-East side and then on the South-West side.[2]

The "rivière à l’Orme" empties on the East shore of “Anse à l'Orme”, which is a natural extension of the Lac des Deux Montagnes. At the end of the course, this river crosses the L'Anse-à-l'Orme Nature Park. This cove is bounded by Pointe Madeleine (North side) and Pointe Boyer (South West side). The mouth of this river is located at:

Toponymy

edit

Since at least 1925, some documents attest to the use of the toponym "Rivière à l’Orme", designating this urban stream. This designation (in its present form) evokes the work of life of “Julien Hubert dit de Lorme”. The latter benefited from a concession in 1668, a lot of land adjacent to the Orme cove, located at the western end of the island of Montreal, just South-West of the “Cap à l'Orme”. In the past, many historians mistakenly believed that this toponymic designation was explained by the presence of elms in this area. The toponymic names "Cap à l'Orme », « Anse à l'Orme » and « Rivière à l'Orme" are intertwined.

The toponym "Rivière à l'Orme" was formalized on December 5, 1968, at the Commission de toponymie du Québec, i.e. at the creation of the Commission.[3]
