Lines 11 Vaudreuil-Hudson, 12 Saint-Jérôme and 14 Candiac have not been running since Thursday after Canadian National Railway Co. (CN) and Canadian Pacific Kansas City Ltd. (CPKC) locked out 9,300 engineers, conductors and yard workers. Exo lines 13 Mont-Saint-Hilaire and 15 Mascouche, which use the CN network, continue to operate as normal because CN rail traffic controllers are not affected by the labour dispute, said Exo spokesperson Eric Edström in a statement. Labour Minister Steve MacKinnon sent the dispute to binding arbitration, he announced later on Thursday.
