I think some of these are complex issues. As I mentioned in response to an earlier question, there's a lot that's been done, particularly since 2013, but there's still a lot that could be done.
We've made a number of recommendations to the department, in particular, for example, to look at training of railway crews involved in safety-critical positions, because the rules have not been updated for a number of years. Whether we're talking about derailments or crossing accidents, they have different causal factors, and so each has to be looked at as issues on their own.
We're certainly continuing to pay attention to things like training and maintenance and inspection practices of the railways as we do our investigations, and there's the safety and oversight provided by Transport Canada.
