Investigations conducted by the Transportation Safety Board of Canada (TSB) are complex since an accident rarely results from a single cause. In the case of the Melville, Saskatchewan, accident on 22 December 2017 several factors led to the uncontrolled movement and employee fatality. The 9 findings below detail the causes and contributing factors that led to this occurrence.

The June 2016 uncontrolled movement of railway cars at MacMillan Yard in Vaughan, Ontario, was no exception. Many factors contributed to the accident, the details of which are contained in the 11 findings as to causes and contributing factors. The investigation established 6 additional findings, including 3 findings as to risk.
Research shows that improving level crossing accessibility for individuals who use wheelchairs improves safety. Possible measures to improve crossing accessibility include the following:

There were many factors that caused this accident, the details of which are contained in the 7 findings as to causes and contributing factors. Furthermore, there were 4 findings as to risk as well as 2 other findings.

A subsequent inspection determined that the 6th to the 44th cars (39 cars in total) had derailed.
Investigations conducted by the Transportation Safety Board of Canada (TSB) are complex – an accident is never caused by just one factor. The March 2015 derailment of a Canadian National Railway (CN) crude oil unit train near Gogama, Ontario was no exception. There were many factors that caused this accident, the details of which are contained in the 13 findings as to causes and contributing factors.
