Mr. Speaker, the work is being done by the federal-provincial-territorial group of officials, which by the way is chaired by Canada and Alberta. That information will be made available as I indicated in my response to the previous question.
However, if the hon. member is interested in some previous studies that have been done internationally, I will be happy to table a document following the conclusion of question period, which outlines some of the international studies that have been done and the figures that they have come up with. This is not official information of the Government of Canada; it is simply a survey of various think tanks and the views of other research institutes.
