The TSB's concern is primarily with those that date from more than 10 years and more than 20 years. If you look at Transport Canada's response to our recommendations, the first response is often that they're going to do a study, they're going to hold a focus group, they're going to consult industry, they're going to harmonize with international standards, or they're going to look at what's happening in the U.S. Then sometimes that approach changes. Sometimes they opt for a voluntary rather than a mandatory approach, and then it just seems to carry on and on.
In terms of what's going on inside the department, I can't answer that question. I can only say that we've just gotten to a point where we say it's too long. There are known risks out there that could be addressed and that aren't being addressed.
