  • avoiding non-essential trips?
  • changing your schedule?

Public transit mitigation measures — November 9 and 12 only

For easier travel on November 9 and 12, various public transit mitigation measures will be implemented.

  • Free transport on train lines exo1 (Vaudreuil-Hudson) and exo4 (Candiac). A valid transit pass is still required for other train lines and other public transit networks.
  • 14 more departures outside of rush hours on train line exo1 (Vaudreuil-Hudson) — Stops at the Dorval, Vendôme and Lucien-L'Allier stations only.
  • 200 parking spaces available at the Les Jardins Dorval shopping centre. Access to the Dorval train station via a protected pedestrian path.
  • Free shuttle service between the Châteauguay terminus and the Sainte-Catherine train station (exo4 line — Candiac) during rush hours.
  • Bus lines 1 (Haut-Saint-Laurent sector) and 28 (Sud-Ouest sector) are rerouted to the Angrignon metro station. These buses normally go to the Mansfield terminus in Montréal. Users of these bus lines will receive free transit fares for the metro.

These measures are in addition to the many new services implemented for the Turcot and Mobility Montréal project since 2011. Refer to the Mobility Montréal website for more information.
