I had thought - originally - that the request was post ITA But I went back to check and found that it was post invite to Ontario PNP,
Below was all they asked:
I had already submitted those as part of EE profile, so I used the same documents and submitted those to OPNP as well.
My status was exactly same as yours, which I documented here as well - Post ITA processing time.
If there were no updates by end of this month, I was planning on ordering GCMS notes. For your case, if I can suggest to just wait for few more weeks, and you should see yours soon as well.
Good luck!
