I am in the same boat as you, applied on 12th sept and still ahvent heard back. I called CIC apparenlty its approved and and they gave me my document numbre and expiry date and said they have to just print it and mail it.. Doesnt make any sense.. I applied for a casre specific inquiry as well.. not heard back.
Yay, work permit finally approved today. Applied on 27 Sep, 2015. Now I can sleep. I so much dread implied status. Good luck to all those still waiting.
