In the same boat here, with the same score and deadlines to meet. Holding out until Dec 11 to submit OINP app. Good luck to you, sir 8)
Assuming things go smoothly and they process the app within 90 days of receipt, I think you're looking at around May/June to get your nomination (realistically speaking). Of course, things could go faster. I am in a similar boat as you (same score, same ET date, but yet to submit app). There are folks who submitted in late October/early November and have yet to receive AOR from Ontario. The 90 day clock starts from the date mentioned in the receipt. I expect to get an AOR sometime in late February. I am preparing myself for May/June decision.
Best wishes to you.
Edit: I was talking about timeline for getting OPNP, sorry. The timeline to getting a PR would be another 3-6 months (or more) after getting ITA.
