REM to close Mount Royal tunnel for 2 years

Next year the construction of the REM will mean the complete closure of the Mount Royal tunnel, and consequent commuting difficulties (“headaches”) for anyone relying on the Deux‑Montagnes and Mascouche lines. CBC lists all the workarounds, TVA highlighting the free train for Deux‑Montagnes passengers but also profiling a family who are picking up sticks from Deux‑Montagnes and moving to St-Jérôme, where the commuter line will not be disrupted.

Update: Another angle is noted here by Global: a lot more passengers will be funnelled to Côte-Vertu and be taking the orange line downtown.
