You haven't done the medical exam?
Usually, in most cases, you are required to wait for medical exam if you have dependants and spouse.
If you are single applicant you can do the UPFRONT medical exam. It means that you can go to a doctor's clinic (suggested by CIC) and request to do an upfront examination for immigration.
The doctor should give you instructions on how to proceed from there.
And if you are asking the length from AOR to MEP (Medical exam pass) the answer is indefinite. I've seen cases where people are still waiting since May AOR. But cases like mine and couple others are quite fast. Mine took only 6 days including Saturday and sunday. Also, here is a website where you can see what other applicants timeline.

I find it interesting how the system works...its quite ... out of order id say.
But expect applications to be processed faster. It was announced that the Express Entry is not receiving enough applicants and so would alter the processing time.

Since
Express Entry is a new system and not enough applications have been received yet, processing times are not available but we have committed to process the majority of applications in six months or less.
