Mr. Speaker, I thank the member for the interesting question.
I would like to point out to the listening public that Canada has an international agreement. We are totally responsible for the costs that are incurred for any safety transportation investigation within the parameters of our domain.
As a result, yes, a tremendous amount of dollars has been devoted to this investigation and there will probably be more. This government has committed itself to keep on, within the realms of human ability and technology, to determine the cause of this terrible tragedy.
