OK ,there are 2 federal MP's in London, Kate Young & Irene Mathyssen . Look them up online. Phone one or both as they do not want in person visitors. Explain to the secretary/assistant your concerns about the application. Don't go into great detail , ask for this person's email and send them an email saying you want the MP to check where your application is at now or whatever your concerns are . They may want you to complete a disclosure form . They can email it to you ,you print it out & complete it, the scan it and send it back to them online. This gives them the right to make an enquiry on your behalf.
The MP can not speed up /change the process but they are the only ones who can make a direct enquiry with CIC on your behalf and get an answer .Also this is part of their job as an MP so don't feel that you are asking for a special favor. Hope this helps .
