原住民社區Mattagami First Nation在申索陳述書（statement of claim）中指出，兩宗漏油事故分別發生於2015年2月和3月，導致有數百萬升石油傾流入濕比利（Sudbury）以北約200公里的戈加馬（Gogama）地區，破壞當地環境和周邊水域，不單對原住民的健康帶來風險，亦損害他們維繫釣魚、狩獵和聚會等原住民傳統的能力。
國鐵拒絕評論訴訟，僅稱已致力清理出軌事故所造成的環境破壞。Mattagami提出的指控未獲法庭證實。Mattagami在今年3月提出控告，但申索陳述書昨日才送達國鐵。
文件聲稱，2015年的漏油對原住民許多生活層面帶來影響，而影響持續超過兩年，故要求賠償：「Mattagami原住民因為他們所依賴的土地、水域、植物和動物受到污染，承受壓力、痛苦和焦慮。」文件指責國鐵有疏忽，在營運業務時路軌維修到員工培訓等均未符合標準，又聲稱國鐵營造了重視速度多於安全的企業文化。
聯邦運輸安全局估計，國鐵的出軌事故向當地生態系統傾倒了多達260萬升石油。局方本月早前發表的報告指，國鐵須為事故負上部分責任，指出軌事故是由於有員工在之前未能檢測到有路軌損壞。國鐵其後回應指已加強安全措施，包括改善員工培訓、提高維修和檢查的標準。
