I'd like Ms. Stanfield to comment on this. The way it is worded now, there's also a change in the applicability. It seems it would only apply to Nav Canada as opposed to all the others, and this is of extreme importance. SMS is applicable to all types of operations, not just Nav Canada.
So worded this way, we had difficulty with the old wording, so that's why we thought that proposed section 5.39 is properly worded, addressing all the operations. And as well, as Mr. Volpe said, there will be other amendments coming to proposed section 5.39 that are taking care of other issues. We believe it is not necessary here, and if it were, it would need to be again amended to cover all operations, and not just Nav Canada.
