Mr. Speaker, as far as I am aware about Public Works and Services, they would know the shipping seasons along the Mackenzie and the western Arctic as well as the Keewatin and the eastern Arctic. They have time-lines that they have to meet before the season starts. On a timely historical basis, they have been able to determine which contracts need to be awarded at certain times and they try to stick by that schedule. There are different circumstances that arise, that maybe a project may be delayed for contracting reasons or the bids coming in were not satisfactory, or the scope of the work may be readjusted, they have to do it again. There are some situations where these things happen. Thank you.
