Does e-cas show "medical results have been received"?
It can take up to 6 months after medicals to have them update your file and move it forward. This is also the point at which they need the return of the background check from CSIS (the other big thing that needs to be done before the application can move forward).
Have you ordered your case notes? If not, you might want to do so, because that will tell you what's happening with your file. You have to wait a month, but at least you'll get some real news at some point.
