Thank you aacan.My first medicals were done and passed Feb. 2017; got extended on Feb 2018.
Jan 24, 2019 I was asked to redo medicals; did them Jan 25; passed Feb. 4, 2019.
We have the exact same timeline. my first medical passed on FEB 2017. an automatic extension has been done around Feb 2018. a new reassessment has been requested in JAN 2019- passed in the same month. IRCC agent told me that my Security completed on 20 FEB 2019 - it was started FEB 2017.
not sure when they are going to ask about the passport to put this nightmare to end.
IRCC process is unpredictable.
