When an occurrence happens, we make a preliminary assessment as to whether we're going to conduct a full investigation or not. We want to make sure that we're going to spend those resources wisely in conducting a full investigation. We collect data, we analyze the data, we write a report, and we publish it. That's a long process.
The report has findings, which are lessons learned from the accident, and there might be recommendations. We don't make recommendations on every report. We make recommendations when we've identified high-risk, systemic deficiencies that need to be addressed that aren't currently being addressed. If we make a recommendation to, in this case, Transport Canada, the minister has 90 days to respond as to how and if the department is going to address the recommendation. We assess that. We're not prescriptive in our recommendations. We don't put in timelines. We recognize that some of these are going to take a while because they might be changes to regulations or standards, they might be new technology, or they might require extensive consultation and might require harmonization with other countries. However, that is the general process.
If we look at all our recommendations issued since 1990, not all of them have been addressed at Transport Canada, but roughly three-quarters of them have been fully addressed and have been assessed our highest rating of fully satisfactory.
