I am not sure if this was posted or not.
Back in October 2019 they said they were on schedule to open in 2021. Got to love COVID for messing up everything.
I guess I will be able to take the REM starting Spring 2024. 3 more years to go.
I do hope in the future, when the Du Ruisseau section opens, the REM/EXO will have the buses go to that station and not the metro.
