Salam,,,
Can you please tell me how many times they request the medical exam?? you can not judge if it is been approved or not from this request,, but if they request to pay PR fee that is mean your application going or it is been approved. looks like they will request good conduct or police certificate, your application now in the final stages.
by the way Canada visa office in Jordan is not doing well, I have friend sponsoring from UAE just took him 3 months yesterday they requested the passport, am very disappointed from the visa office
