I'll let the officials answer that, but my understanding is that Canada, of course, is not providing the information: this is information being provided by the airlines to the American authorities.
In order to set up a new institution, which would then take in information from passengers coming to Canada or in Canada who would then be overflying the United States...would necessitate the creation of an entirely new administrative body. My understanding is that the cost would be somewhere in the neighbourhood of $150 million over and above the cost that this puts us to. So the issue is a significant one in terms of cost.
I don't know if there are any further details on those costs from the officials.
