According to Andrew McCreath on BNN, about 10 million Crescent Point Energy shares will be needed to be bought by Friday September 21st, 2012 when Crescent Point Energy will be added to the TSE 60 on the Toronto Exchange. He states this in the following clip if you go to the 3.35 minute point on the clip:

This most likely accounts for part of the 3 million Crescent Point shares which traded yesterday on Monday Sept 17th.
