So instead of uploading medical, I should add a separate LOE explaining my situation?Just submit your ITA application with all the available documents except medical. Also submit an LOE stating that since you are based out of Canada you need the IME request in order to proceed with the medical.
I did read on this link shared above:
https://www.canada.ca/en/immigration-refugees-citizenship/services/immigrate-canada/express-entry/documents/medical-exams.html
but wanted to confirm if someone has already done that or not.
