I used Walgreens. You'll have to work with the store person and tell them the requirements. I've had good experience with Walgreens. My photos were accepted.
I have been able to contact them using the TextNow app. Try using the TextNow app and get a local Canadian number through the app.
You can call this number from within Canada only or using a local number obtained from apps like TextNow. Good luck.
Did you raise any Ready to Travel webforms before getting the re-medical request? Also, are you in India?
Learned from the agent that the medicals were extended until Sept 20th - Are you referring to an IRCC agent?
I have received a generic reply stating that the case is in process with the responsible office. I did raise a ready to travel webform on 10/22. Nothing substantial.

What is the process in general? Does COPR get extended in the EE profile first and then the applicants receive the email with AL? How does one get notified of the COPR extension?
