Actually, CAIS is part of the APF, but it is a statutory program, so you are correct that it would take any one of the parties two years. They would have to identify in advance that they want to remove themselves from it.
As to the federal–provincial ministers, when they first met in terms of talking about a replacement for CAIS, and as they consulted with industry, a number of industry members identified that they did want a margin-based program as a component of a new suite, but that wasn't enough.
So there has been a lot of progress with federal, provincial, and territorial ministers, especially in the last meeting, as the minister just mentioned, to replace CAIS with not one program, but a suite of four programs: the first one is a producer savings account for the top tier; then a new margin-based program, which pretty well covers a lot of new features to the margin base; then an enhanced production insurance program; and then a final area, which is the catastrophic disaster program to take care of other costs that the other three programs do not cover.
There's been a lot of progress. Right now we are working with the federal–provincial–territorial officials and we are going to present recommendations to ministers in June for the next APF.
