Well, one good thing about no med request yet is that your medical won’t expire, requiring you to do it over again (and pay again!)— I think Quebec applicants get Ned requests later in their process partly for that reason.
I know it’s frustrating, but at least CSQ is done— and if it came back in March that is actually pretty quick turnaround time! And the ‘normal’ application process started after CSQ, so at least you’re on your way
You can always order GCMS notes if you want to know which parts of your application are done. But take heart: December in general has been having amazingly quick processing time compared to people who applied earlier in 2018 — a lot of people are still waiting!
