I called them 3-4 times..everytime I call they say your file is under the processing time of 19 months, everything else looks good. not a single time I have been given any extra info other then what I can see on my gckey.
CIC will only tell you what we see on our gckey account...also, they can tell if there is a note on our file from the immigration officer. they don't have any extra info on our files...
we have the exact same timeline...it's just my medical passed on 26th may 2018...I got GU on 21 may 2019...I called CIC and they said that the update is for medical extension...officer requested to extend the medical.
