I called IRCC yesterday and got to know that my eligibility, security etc. were all cleared by the officer on the day my remedical request was triggered (Jan-29-2020), and that he was now waiting just to see my updated medical reports before finalizing the application.
He also told me that remedical is sent only when the officer is satisfied with everything else, and the older medical results have expired. So yes, getting remedical request is definitely a sign that the case is close to the finish line.
Friends – from here on, it may take some time for the actual case closure processing and to trigger PPR email, but the case shouldn’t have anymore red flags tagged on it as such.
