WAS razaalirafique,
If you didn't send any email to CIO yet, you must do it. There is no harm in sending an email inquiry to them if application arrived there 8 - 10 weeks ago. Since your application receipt date is same as mine, you have already crossed more than 10 weeks. Here is the email to check the application status update:
CIO-Sydney-Search-Enquiry @ cic.gc.ca
You should send email from the same email ID which you have given in the application. Also given your first name, family name, date of birth, place of birth, application receipt date, application receipt time and receiving person name. If you have scanned copy of Generic Application Form, you can attach with that email.
As soon as you send your email, you will receive an automated reply saying that expect a reply within 20 working days (4 weeks). I received reply in 10 working days (2 weeks).
Good luck for you.
