Here's my situation. I guess it could be the same for many of you guys.
I'm outland (NB), my PR application has been received on July 2019, by December 2019 my Med and Bio has been done.
Jan 2020 I had some additionals documents to send.
Feb 2020 I received a letter for Pre-arrival invitation services. After that I never heard back from IRCC. My account show eligibility and background are in process until now.
Otherwise, last week I called IRCC (Halifax number), they told me everything was done with my application, it's because de COVID specially the travel restrictions, I did not received my CoPR to come to Canada.
