On Saturday, March 7, 2015, a CN train carrying crude oil derailed near the Northern Ontario community of Gogama. There were no injuries or casualties, and due to the quick, coordinated and comprehensive emergency response of CN, local first responders, provincial and federal agencies, and teams of specialists brought in by CN, the impacts on the surrounding environment were minimized. CN's own investigation into the March 7 derailment identified the cause as a track infrastructure failure, or a broken rail, resulting from an internal rail flaw defect. The full circumstances of the derailment remain the focus of an ongoing investigation by the Transportation Safety Board which has also stated that it is looking at track infrastructure failure as the cause of the March 7 derailment. CN is committed to running the safest railway in North America and to learning lessons from every incident to improve safety. We continuously work to strengthen our safety culture, safety practices and safety defenses through the training of our people and substantial, targeted investments in our infrastructure. We continue to implement leading-edge technologies to mitigate risk through increased monitoring of track and equipment, as well as ongoing data analysis to identify potential risks before accidents happen.

Since the day of the derailment, CN's responders have worked diligently to remove oil from the river, prevent oil from migrating downstream, and remove oil-impacted soil and sediment at the site. These efforts have been very successful and as a result, there is no longer a source of oil contamination in the soil or sediment that will cause continuing impacts to the water, wildlife or natural environment in the Makami River and Minisinakwa Lake.

Occasionally, very small patches of sheen (rainbow or silver film on the water surface) can be found on the surface of the river near the derailment Site, but sheen presence is continuously decreasing. Sheen is an extremely thin film of oil which floats on top of the water. These minor sheen appearances will continue to decrease as they quickly get broken down into harmless components by natural processes such as exposure to sunlight, river currents, and wave action. This sheen does not pose an unacceptable risk to humans, wildlife, or the natural environment. Click here for more information on sheen.

CN concluded the 2015 remediation and restoration activities in November 2015. Over the winter, CN will visit the site periodically to conduct monitoring and sampling tasks. Crews will return to the site in the spring of 2016 to complete the remaining work which includes final restoration tasks and flushing, and collecting remnant oil from the railway embankment. Long-term monitoring will continue in 2016. The results of the sampling events will continue to be shared with the public and regulatory agencies including the Ministry of the Environment and Climate Change, Environment Canada, Ministry of Natural Resources and Forestry, Fisheries and Oceans Canada, and the Sudbury & District Health Unit.

CN takes the health and safety of residents, wildlife, and impacts to the environment very seriously, and is committed to a full environmental clean-up of the spill and remediation of the environment.

CN would like to thank the residents of Gogama and of the Mattagami First Nation for their patience, understanding and assistance throughout the clean-up process.
