4 possible reasons for this delay in the 44th draw:
1. Maybe they do not want to have 3 draws in a month (as is expected in coming November) so they have shuffled the draws schedule a bit for the 44th draw...
2. Maybe they do not care about how many people are below 482, they just want to issue ITAs to a beforehand fixed number of people and the number of people below 482 are too many to come in a draw. So maybe they are waiting for there to accumulate sufficient number of people above 482 for their next draw.
3. Maybe the draw is on Friday instead of this Wednesday. It has happened before as well that draws took place on Friday when a Wednesday draw is missed.
4. Maybe they are implementing the long-talked-about changes before the 44th draw. We are halfway through Fall 2016, the time for the proposed changes is at hand.
Adding 5th probable reason:
5. As stated here, may be CIC is waiting to get more applicants for a specific cut-off, on the same time if they lower the cut-off they will have to issue way more ITAs than what they've planned.
