My medical expired in May 2025 but was showing as still "completed" in the tracker after that so I wouldn't worry about this. After it expired I phoned IRCC to ask what would happen if the medical expired and they said just to wait for any further instructions. I got eCOPR earlier this month (after 21 months since my application back in Feb 2024) and they never asked me to do a re-medical, however this may be because although I was originally an Outland application, I have been in Canada for over a year. I'm not sure really.
