原住民社区Mattagami First Nation在申索陈述书（statement of claim）中指出，两宗漏油事故分别发生于2015年2月和3月，导致有数百万升石油倾流入湿比利（Sudbury）以北约200公里的戈加马（Gogama）地区，破坏当地环境和周边水域，不单对原住民的健康带来风险，亦损害他们维系钓鱼、狩猎和聚会等原住民传统的能力。
国铁拒绝评论诉讼，仅称已致力清理出轨事故所造成的环境破坏。Mattagami提出的指控未获法庭证实。Mattagami在今年3月提出控告，但申索陈述书昨日才送达国铁。
文件声称，2015年的漏油对原住民许多生活层面带来影响，而影响持续超过两年，故要求赔偿：“Mattagami原住民因为他们所依赖的土地、水域、植物和动物受到污染，承受压力、痛苦和焦虑。”文件指责国铁有疏忽，在营运业务时路轨维修到员工培训等均未符合标准，又声称国铁营造了重视速度多于安全的企业文化。
联邦运输安全局估计，国铁的出轨事故向当地生态系统倾倒了多达260万升石油。局方本月早前发表的报告指，国铁须为事故负上部分责任，指出轨事故是由于有员工在之前未能检测到有路轨损坏。国铁其后回应指已加强安全措施，包括改善员工培训、提高维修和检查的标准。
