It's 448 - what do you suggest?
Basing my assumption on past trend, it seems unlikely for the score to go below 450 anytime soon. As per the last draw the cutoff CRS score for ITA was 457. You can find the update here http://www.cic.gc.ca/english/department/mi/index.asp?expand=mi-pr-express#mi-pr-express
In fact, my score is 451, I thought of waiting for a direct invite, but when I got the PT NOI on Oct 8th, I applied and that decision was right for me as it never came down to 451 since I created my profile.
If you get an invite from OINP, I would suggest you keep all the documents ready and wait until 1 week to the expiry of 45 days deadline. If the scores for ITA does not go down or you do not get an ITA by then, you can send your file to OINP. Then, at least you would not miss the opportunity to apply for OINP.
