In our previous post, we visited 14 places in Montreal where the Saint-Pierre River once flowed. We resume our tour moving south of Meadowbrook with 12 stops and, once again, a few pleasant surprises. South of Highway 20, these spots are scattered all over southwestern Montreal, from Lachine and LaSalle to Pointe Saint-Charles.
(1) Geomorph, Saint-Pierre interchange; (2) Former Lac Saint-Pierre or Lac-à-la-Loutre now Turcot interchange; (3) Carrefour Angrignon, LaSalle; (4) Snow depot, LaSalle; (5) Angrignon Park ; (6) Douglas Institute; (7) Beurling Park; (8) Woonerf Saint-Pierre ; (9) Lac-à-la-Loutre Park; (10) Grenier Park; (11) Sutherland-Sackville-Bain Park; (12) Arthur-Therrien Park; (13) D’Argenson Park; (14) Joe Beef Park.
The map for this section shows a number of other Montreal rivers. From west to east: the Glen in Westmount, the Ruisseau de la Montagne along Côte-des-Neiges Road, the Ruisseau Prud’homme, the Torrent de la rue Peel and lastly the Petite rivière in Old Montreal. Note the location of the old Canal Saint-Gabriel between the St. Pierre River and the Petite rivière. Click on image to enlarge.
A geomorph in Lachine
At this point, we’d be remiss if we didn’t mention a geomorph (a geographical feature that still follows the contours of a river even though the river is no longer there) in the Saint-Pierre district of Lachine, identified by environmental historian Laetitia Deudon : the Saint-Pierre interchange (1), where the layout of the streets and even the highway ramps are reminiscent of the river’s former presence.
According to Virginie Destuynder of the École de technologie supérieure, the river drained a basin of 56 km2. It flowed for 43 km, not counting the detour to Pointe-à- Callière via the Saint-Gabriel canal, which added another 3.9 km to its course. At the foot of the Falaise Saint-Jacques, the river formed Lac-à-la-Loutre, a shallow lake covering an area of 30 ha (2). (The lake was drained in the 19th century with the creation of the Lachine Canal, an old dream dating back to the early days of the French colony, in order to bypass the rapids on the St. Lawrence River).
On to Angrignon Park in LaSalle
Today there is nothing left of the river in Angrignon Park (5); according to Professor Valérie Mahaut’s map, it flowed in the southeast corner, at the corner of des Trinitaires and de la Vérendrye boulevards. Could the park’s ponds have originated from the river? According to François Arteau of Les amis du parc Angrignon, who is currently researching the park’s history in preparation for its centenary, this is not the case: the ponds were created entirely by human hand between 1956 and 1958.
Next stop: the Douglas Institute
We move on to the Douglas Institute (6), where a bowl at the corner of Stephens Street and Champlain Boulevard could be, according to Christian Nadeau, a member of the former Comité de protection et de mise en valeur du patrimoine bâti et naturel de Crawford Park, a remnant of the ancient watercourse. The river also used to flow through Beurling Park (7).
Sud-Ouest borough
In Saint-Henri, the borough of Le Sud-Ouest has built a woonerf (8) (a shared street for pedestrians, cyclists and cars) over the Saint-Pierre collector, stretching from Sainte-Émilie Street to Parc du Lac-à-la-Loutre. The construction of the collector, a titanic work built during the Great Depression to put the unemployed to work, channeled much of what remained of the river and left a large scar there.

A salute to the former Lac-à-la-Loutre, parc du Lac-à-la-Loutre (9), at the corner of Saint-Patrick and Courcelle, lies at the eastern end of the former lake, at the confluence of the Saint-Pierre River and the ruisseau Saint-Martin. A micro-forest has been planted here, and a community garden adds greenery to this area of dense condo development.

Verdun (Sud-Ouest borough)
We had previously visited the Duquette, Grenier (10), Sutherland-Sackville-Bain (11) and Arthur-Therrien (12) parks during a tour organized as part of the recording of a 2023 podcast about the Saint-Pierre River by the Centre de recherches interdisciplinaires en études montréalaise (CRIEM). With its elongated shape, Grenier Park (10) on Strathmore Street in Verdun can be considered a geomorph, embracing the shape of the river even though it’s no longer there. The mouth of the Saint-Pierre River where it flowed into the St. Lawrence River originally faced Nun’s Island and was located where we now find Arthur-Therrien Park (12). Today, the outlet of the Saint-Pierre collector can be found there, overlooking the aptly-named “Baie des Capotes”; this nickname comes from the way the area looks when the collector’s overflow is emptied directly into the St. Lawrence during heavy rains. Beurk!
At d’Argenson Park (13), the Sud-Ouest borough has recently redeveloped with a pump track (!), the Saint-Pierre River is recalled by a rain garden, a nature-based solution for controlling rainwater runoff. Another spot on the St. Pierre River’s path is Joe Beef Park (14).
Old Montreal
One last place that recalls the Saint-Pierre River is the Dream Collector at the Pointe-à-Callière museum in Old Montreal. It’s worth noting that the river was diverted in part into the Little Saint-Pierre River by the Sulpicians to power mills. The museum highlights the William Collector, a true 19th-century engineering jewel which trapped the Little Saint-Pierre River, made unsanitary by the lack of proper sewers in 19th-century Montreal. It was here in 1642 that the first Montrealers, Sieur de Maisonneuve and Jeanne-Mance, landed. It doesn’t get more Montreal than this!
