Since May 11, 2020, the Mascouche line has temporarily terminated at Ahuntsic station (with some trains continuing to Central Station via an alternate route partially using the CN Taschereau intermodal yard to access Central Station) due to the ongoing conversion of the Deux-Montagnes line into the mainline of the Réseau express métropolitain (REM) light rail system. Once the downtown section of the REM is completed sometime in 2022, a new station called will open, expressly designed to ensure smooth transfer of users between the Mascouche line and the REM, and replacing Ahuntsic station as the line's new terminus.
