Canada’s federal government has instructed workers and management in the St. Lawrence Seaway strike to sit down with a mediator this Friday and hash out their differences, as groups ranging from grain farmers to steelmakers feel the squeeze. The job action by 361 Unifor members at 13 of the 15 locks along the key trade corridor kicked off Sunday, shutting it down immediately. The union and management authority both said on Tuesday they would comply with the government notice for mediation (source: CBC).
