The City of Montreal and Government of Quebec took over the project in 2022 following intense opposition to some elements, including the downtown section, which officials quickly scrapped.
In January, the group leading the structural project study released a preliminary report saying it would "evaluate options" to extend the REM de l'Est's initial Montreal Island-only route into Laval and the Lanaudière municipalities.
The mayors of Laval, Montréal-Est, Terrebonne, Mascouche and Repentigny are expressing a preference for an option that would see the line begin in Mascouche, cross Terrebonne and northeastern Laval (via autoroute 25), continue south across Montreal Island and meet the blue and green metro lines (at the future Lacordaire station and Assomption station, respectively), before turning back east toward Montréal-Est and Pointe-aux-Trembles, and ending in Repentigny.

"We are convinced that this is the route that allows for the best development of our territories and optimal mobility for the benefit of our citizens of today and tomorrow," Laval Mayor Stéphane Boyer said in a statement.
"Moreover, the passage of this major infrastructure in Laval paves the way for one of the last major sectors to be developed on our territory, which is a golden opportunity to plan an exemplary neighbourhood in terms of sustainable development that could set an example throughout North America."
