The Réseau express metropolitain (REM) will be a new integrated network linking downtown Montreal, South Shore, West Island, North Shore, and the airport. Once completed, the 67-km line will be one of the longest automated metro lines in the world. The REM opened its first segment on July 31, 2023, with five new stations spread over 17 kilometres. Since its opening, over a million people have already used the service, which has maintained a 99 per cent reliability rate in recent weeks. Construction continues on the remaining antennas, with a completion rate of 85 per cent. Testing will begin in these areas in spring 2024.
