Wow! That is some great information that you have passsed on dear friend!
So according to my understanding the medicals need to be valid at least for around 6 months before we get our COPR approval right?
Would you please be willing to share your entire timeline?
This valid may be the standard one that I was requested. However, there are many other cases (that I know) they still can get the CoPR approved with ME in less than 6 months, so it is subject to the decision from IRCC officers and our luck.
Below is my timeline:
PR submission: Nov 2020
AOR: Jan 2023
Medical Request: May 2023 - Apr 2024 - Sep 2024 (3 times)
ADR: Feb 2023 - Apr 2023 - May 2024 (3 times)
Pre-arrival service: end May 2023
CoPR and Visa request: Oct 2024 (Both valid still Sep 2025 that are same expiration date as the last ME)
Landing Canada: Dec 2024
Total: 47 months
Hope it will help and good luck to you !
