I can speak, Mr. Chair, generally to that question.
We have a policy on occurrence classification, which is available on our website, but which we're happy to table with the committee. It outlines the things we look at. In particular, our role is to advance transportation safety. I do have the statistics in front of me, and in 2021 there were about 214 marine accidents and another 860 or so marine incidents. We're talking about close to 1,200 occurrences. We can't investigate every one, nor does every one warrant the use of limited resources to conduct a full investigation with a public report.
What we look at is, what do we know about the occurrence? Is it something that we're already watching through our watch-list? Is it something that we know is of interest from an international perspective? Was there loss of life? Was there significant property or environmental damage? There's a series of criteria that the directors of investigations use in all four modes to determine which of the many, many occurrences that are reported to us warrant a full investigation. Within that, there's an initial scoping of the investigation to determine the different lines of inquiry that we're going to look at.
The TSB was certainly aware from the time this vessel was encountering difficulties, and then the subsequent fire, and then we had to wait until it was safe to board the vessel. Certainly, this was an example of one that we felt warranted a full investigation and public report.
