Mr. Speaker, the way I understand it, even though it is a more permanent longstanding agreement, it can be reviewed every four years. So in that respect, this country and the United States can review the agreement and make or propose changes, and bring those changes to the attention of this. It is not an exclusively permanent unchangeable agreement. It is an agreement that can be reviewed every four years and in that way it makes it more permanent, but it is not an absolutely permanent fixture between the two countries.
