2022: moving closer to commissioning of the first REM segment

In the greater Montréal area, a number of sites are active at the same time in the effort to continue REM construction in 2022. Some key milestones to watch out for this year: Operational testing will end on the South Shore; stations will be commissioned and launched along the segment from the Brossard terminal station to Central Station (excluding the Griffintown–Bernard-Landry station); modernization work will continue on the Mont-Royal tunnel; and work will pick up on the North Shore and in Pierrefonds-Roxboro.
