Welcome on board, everyone here is on the same boat where patience is the watchword.
Mississauga handles the first stage of the application after which it's sent out to ur country of origin or country in charge of your country like the case of Nigerians for eg that is grouped under Ghana for further processing. They handle the remaining part in most case, some cases they might ask u to submit PPR in ur country of residence or as the case maybe.
And yes u are not alone. I currently live in US. Applied Nov 2nd, SA and file transfered on 24th Nov and current status shows started processing on 8th Dec 2016, Medical received. So ur application is right after mine. All things being equal am expecting to hear from AVO anytime from May/June even though I pray they suprise me.
All the best and stay positive. Happy holidays to u too
