Oh, absolutely. And that's what we're saying; we would not propose something that we felt increased, in any material way at all, safety risk. We have both very objective and proven scientific methodologies to establish that. We also have some very subjective reviews that are made by people with the experience to do that.
So this is not a safety issue when it comes down, at the end of the day, to these things. It's not up to us. There is the independent safety regulator who reviews all that and then makes another judgment, and that's Transport Canada.
