Perform preliminary work for the REM de l’Est project
Reference Project: Infrastructure, transportation system, building and station, operation and maintenance, environmental impact assessment

The REM de l’Est project involves the creation of a 34 km automatic overhead and underground light rail system with 23 passenger stations.

The purpose of this line is to serve the East end of the island of Montreal from downtown. It is composed of a common line serving the boroughs of Ville-Marie and Mercier-Hochelaga-Maisonneuve which then forks into two, one branch serving Rivière-des-Prairies Pointe-aux-Trembles and the other Montreal-North.
