I got the AIP and medical request together 2 months after my background check started, but I am aware there are others from Jan/Feb who still haven't received medical requests or anything. Given that people from 12 months ago from QC are still just receiving their PR now, it's a long process for most, much longer than for the rest of Canada. I seem to be the abnormality not the norm in my timeline. I wish I could tell you what I did to get mine moving, but I have no idea! Sorry I can't be more helpful
