Good morning, I was in this situation too. I called 2 different agents at IRCC. Te first one didn’t seem so knowledgeable and said if I was asked, I should provide documentation. The second agent also wasn’t knowledgeable but did conduct a thorough research to know exactly what to do in this situation. The second agent told me after the research that I do not need to provide documentation and I should include a letter explaining I am eligible. So I did, I included the letter and submitted my PR application 3 weeks ago. So far no issues have come up. The latest update is me passing my medicals.
