You're absolutely correct. This is why the initiative that was launched—the indication of the federal government to take leadership in conducting a review of the Agreement on Internal Trade—required the full participation of the provinces. This is an agreement between the federal government and each province and territory. That's why it was a welcome development that the provincial premiers, last summer, indicated a willingness to engage and actually set a date for completion of these negotiations in 2016. We have at least an agreement of principle on the usefulness of conducting such a review.
