Multidisciplinary Expert Committee

Expert Committee

on Architecture and Urban Integration

Why a committee on Integration?

To ensure the exemplary integration of the REM de l’Est into the urban landscape, the Government of Québec has appointed a committee of independent experts to assist in developing a high-quality, world-class architectural vision.


Committee Mandate

To establish the main architectural principles

The REM de l’Est project is at the start of the design phase. The Committee’s main mandate will be to contribute to the future network’s architectural plans and its urban integration along the entire route. The Committee’s input will be used to establish the prescriptive design that will be included in the REM de l’Est’s Request for Proposals (RFP). The Committee will actively monitor the project’s progress throughout its development and will contribute to its detailed design, which will be created by the consortium selected at the close of the project’s Request for Proposals.


The REM de l'Est project is currently in the design phase, which means that certain elements, such as the architecture, have yet to be fully defined. Because the committee is involved early in the design process, its recommendations can be incorporated at the earliest stages of the design.

Detailed mandate description


The design will be developed in 4 stages:

The REM de l'Est : a project under development

To better understand how the Committee’s work will impact the development of the REM de l’Est project, it is necessary to visualize the project’s various phases. We are currently still at the planning stage. The route has not yet been fully determined and several elements remain to be defined, such as the project’s architectural design and urban integration.

The experts

The committee is made up of experts from many fields of expertise to ensure a global reflection on the project from a plurality of points of view. The members were nominated by the Government of Quebec.

Representatives from the City of Montréal, the Government of Québec and CDPQ Infra will attend the Committee’s workshops.



The REM de l'Est project

The REM de l’Est is a fully automated electric light rail project that includes 23 stations over 32 kilometres. It represents the largest investment in a public transit project in Québec. It will connect the east end of Montréal and the CÉGEP Marie-Victorin directly to downtown Montréal, to meet the significant mobility needs of these areas.
