The final rule came out in 2008. That was when we first learned of how the Americans would actually spell out how the U.S. government intended to implement the law. It set out the rules they would carry out.
At that point we continued to negotiate with the Americans, looking for exemptions from that rule. In fact, the Americans did provide us with a very important exemption, especially looking at the southern Ontario situation: individuals flying from Toronto, let's say, to other parts of Canada would, for a large part of many flights, cover American airspace; the Americans exempted us from that final rule as a result of the negotiations.
The negotiations continued until late in the day. At the point that we felt there could be no further progress made in terms of exemptions, we were also advised in no uncertain terms that the Americans intended to implement the law at the end of this calendar year, so it became very important then for us--recognizing that no further negotiations were available to us and that we had the best deal we could get under the circumstances--to bring in the legislation.
Given that the changes in terms of privacy and roughly the information being provided were the same as what had been negotiated by your government some years ago, we felt that this would be the appropriate time to bring the legislation forward.
