Hi Sunshine,
I'm in yours and lab's situation too
I applied in September 2011 and in July 2012 I got a letter from CIC requiring further evidence of my common-in-law relationship.
I called CIC 2 days ago and the agent told me that my medicals appear in the system but he didn't have any dates regarding when my application will be reopened

and he added he could see my application was in queue.
My case is pretty simple: no kids, no previous marriages, no criminal offences/records, no health issues.
It's so frustrating especially now that it seems CIC is processing application way faster. Sometimes I wonder if CIC didn't totally forgot of us
