Sixty years of promises, studies and patience
Completing Highway 20 is not a new idea. The land has been in government hands since expropriations began in the 1960s. Here is the road travelled so far — and the one step still to be taken.

Next step
Political decision and inclusion in the PQI
1960s
First sections built
The first sections of what is now Highway 20 are put into service in the area.
1964
Expropriations on Île Perrot and in Vaudreuil-Dorion
The Québec government expropriates several parcels of land to make it possible to complete the highway. These properties still belong to the government today.
1960s to 2000
Land acquisitions and studies
The Ministry of Transport (MTQ) continues to acquire land and conducts numerous technical studies.
2000
Analysis of a completion project
The MTQ formally analyzes a project to complete Highway 20. The project is included in the Québec Infrastructure Plan (PQI).
2009–2010
Halted before filing with the BAPE
Work is stopped just as the project is about to be submitted to the BAPE, and the project is removed from the PQI by the Québec government.
2010–2018
Repeated calls to revive the project
The MRC, local municipalities and the public repeatedly call on the ministry to revive the project.
2018–2022
Mobility working groups
The Québec government establishes a working group to develop, with the community, a shared mobility vision for the Highway 20 corridor.
2023
A new study
The Ministry of Transport and Sustainable Mobility (MTMD) begins a new study on optimizing Highway 20.
2023
Economic impact study of the status quo
Développement Vaudreuil-Soulanges commissions Raymond Chabot Grant Thornton to conduct an economic impact study on the cost of not completing Highway 20.
February 2024
The MRC de Vaudreuil-Soulanges’ unanimously adopted brief
Supported by an economic impact study and a consensus among the mayors of Vaudreuil-Dorion and the municipalities of Île Perrot, the brief proposes an alternative to the MTMD’s scenarios: uninterrupted traffic flow with no traffic lights.
May 2025
The MTMD’s technical recommendation
The ministry concludes that an uninterrupted highway link is the most advantageous solution, based on its multi-criteria analysis and cost-benefit analysis. For the first time, the region and the government have reached the same conclusion. These studies remain valid for a limited period of 10 years, after which they must be updated. The time to act is now — before the entire process has to start over.
January 2026
Meeting with the minister and a resolution
The MRC meets with the MTMD and adopts a resolution calling for the project to be included in the PQI. Municipalities and the business community follow suit.
Next step
Inclusion in the Québec Infrastructure Plan
This is the key that unlocks everything. Without inclusion in the PQI, the project cannot move forward. This is where your voice matters, just months before the October 5, 2026 election.
