We shall see.
There does not appear to have been a draw today.
Why?
What's to stop someone with a 455 from entering the pool in 2016?
It doesn't work that way. There are lots and lots of 445s, 440s, 435s, and so on. Dropping the score suddenly, even once, would lead to a massive inrush of applications that would have to be processed all within a short timeframe.
Look at the mid-year statistics:
http://www.cic.gc.ca/english/resources/reports/ee-midyear-2015.asp
A score of 550 would get 357 people. Dropping it to 500 would have brought it to 395 (a minor increase). Dropping it to 450 raises it to 2,181, a major increase. In fact, that's a 452% increase, which brings it to more than the size of the draws they usually like to do. Dropping it to 400 would increase it to 10,951 people. In other words, they get 5x as many people at 450 than 500, and 25x as many at 400 than 500. Dropping it another 50 points to 350 would kick it to 25,548 people getting ITAs all at once. That's utterly ridiculous.
There's a limit to how low the score can go. If they hold a few back to back, we might see 445 soon. We're not likely to see 400 in the near future, if ever.
