Lachine Canal National Historic Site


Work done by Bell Canada affecting the Lachine Canal path: Monk bridge area

As part of the redevelopment of the Turcot Interchange, Bell, at the request of the Quebec Ministère des Transports, will install new manholes and conduits.

The construction work will involve reducing the width of the Lachine Canal path between Chemin de la Côte-Saint-Paul and Place Turcot. Signage will be in place for cyclists as they will have to switch lanes on the canal’s path.

The construction work will begin on November 3rd and continue until spring 2015.

Thank you for respecting temporary signage.

Montréal, September 23, 2014 – Ville de Montréal will be carrying out construction work on water pipes, mainly under the Lachine Canal and along its shorelines as well as in parc Saint-Patrick, starting September 29 and until August 2015, without any interruption during the winter.

This construction work is necessary to repair these water mains that supply a large part of the drinking water distribution network in downtown Montréal and that have been subject to numerous breaks in the past few years.

Location and nature of the construction work

This construction work consists of rebuilding the pipes and their equipment on the north and south sides as well as under the Lachine Canal. The northern and southern phases will be carried out at the same time. A new, large-diameter pipe will be inserted into the existing pipe under the canal. The area will be restored once all the work has been completed.

South sector – parc Saint-Patrick, south of the Lachine Canal:

  • construction of access pits: September 2014 - February 2015
  • insertion of pipe: May - July 2015

North sector (Lachine canal shoreline, on the ground of Parks Canada):

Between rue du Séminaire and rue du Square-Gallery - construction of pipes, valve chambers and other work: September 2014 - August 2015

Preliminary work will be necessary to set up the detour roads for the path along the Lachine Canal as well as other special measures (fence marking the boundaries of the worksite, signs, etc.).


This work requires cutting down 6 trees along the canal shorelines. Compensation measures have been established with Parks Canada, in accordance with Ville de Montréal's policies. The other trees there will be protected.

Path along the Lachine Canal

  • Part of the path on the north side will be completely closed while the work is under way. Between rue Richmond and rue Wellington, traffic will be transferred to the south side of the canal.
  • Access for cyclists and pedestrians will nevertheless be maintained between rue Richmond and rue du Séminaire (however, the path will be closed just before rue du Séminaire).
  • Road signs and directional signs will be set up.

The Jacques Cartier and Champlain Bridges Incorporated

Detour set up for the section of the Lachine Canal bike path under the Bonaventure Expressway in Montreal

Longueuil, April 9, 2014 – The Jacques Cartier and Champlain Bridges Incorporated (JCCBI) would like to advise cyclists that a detour will be set up on the section of the Lachine Canal bike path that passes underneath the Bonaventure Expressway, from April 21 to May 15, as well as from November 15 to late December.

This detour is necessary to begin mobilizing major work planned for this year on the federal section of the Bonaventure Expressway at the Lachine Canal.

During these periods, cyclists will be invited to use a detour set up on the Wellington Street Bridge via the existing bike path network. See map of the detour (PDF, 1.5 Mb).

To minimize impacts on cyclists and pedestrians, a clearly defined path will be made through the construction site from May 15 to November 15, in order to keep this section of the Lachine Canal bike path open during the busiest time of the year.

Cyclists and pedestrians are asked to be careful around this major worksite.

As well, the detour will occasionally be re-implemented during complex manoeuvres between May 15 and November 15. During these periods, the path through the worksite will be temporarily closed.

These closures will include:

  • night closures occurring mainly between 11 p.m. and 5 a.m.
  • closures that can last between 12 to 72 hours
  • very short closures from 10 to 15 minutes

We’d also like to remind cyclists that the detour route will be permanent from November 15 until the bike path closes for the winter season.
