Project overview

The Port of Montreal's rail network currently has close to 100 km of track to serve the fourteen terminals. Each year, it transports 2,500 km of railcars.

Project works include:

  • Installation of 6 km of additional railroad tracks and switches
  • Complementary work to develop the internal rail network.
  • Relocation of the Port Road

Project timeline

May 2017

$18.3 million in financial support from the Government of Quebec under its Maritime Strategy

April 2018

$18.4 million in financial support from the Government of Canada to optimize its intermodal network under the National Trade Corridor Fund.

June 2018

Awarding of the mandate to increase rail capacity to the firm CIMA+.


  • Project design and planning phase
  • Field studies (noise, dust, fauna, flora and traffic)


  • Integration and verification of plans and specifications
  • Finalization of the Environmental Impact Assessment (EIA)

As sustainability is at the core of the MPA's business processes, the project team identified several measures that will make it possible to improve the project on this front. They include:

  • Optimization of reuse of excavated soil as backfill (so that it is not necessary to move the soil by truck)
  • Use of recycled concrete in the foundation of the new Port Road
  • Use of recycled paving on the new Port Road
  • Composite railroad ties made of recycled plastic

Mitigation measures

Once the Environmental Effects Evaluation is completed, the Montreal Port Authority team expects that the construction work will not have notable impacts on cohabitation with the adjacent neighbourhoods.

However, to avoid impacts on the surrounding population, mitigation measures have been included in the project and will be closely monitored and adjusted as needed. A resource person is specifically assigned to carry out this monitoring as part of the project. Here are some of the planned mitigation measures:

  • The work is mainly scheduled to take place on weekdays between 7 a.m. and 5 p.m. Occasional work may also be required during the day on weekends.
  • Spot checks will be conducted in the vicinity of the work site to monitor noise levels.
  • Particular attention will be paid to areas where there is machinery, which will be installed as far away as possible from dwellings.
  • Mobile machines will be equipped with white noise back-up alarms. In addition, the roads used by the trucks will be maintained and dust suppressants will be used as required.
The work site will be fully monitored at all times and as the work progresses, other mitigation
measures may be implemented as needed.
