It's a very disappointing response from London I'd say.
If the initial review is not even started after almost a year, the whole process may take another year or so.
Here is what the AOR I received from London VO states about the overall process:
"Your application will first go through a pre-assessment done by Case Analysts. Case Analysts do not make decisions. They will go over the facts of your application and deepen the understanding of your circumstances before your file is assigned to an officer for processing. You may receive a request for additional evidence.
Once your application is assigned to an officer, the first step will be for the officer to review whether you meet the requirements for the Family Class category you applied under. This is called: Eligibility.
Once eligibility is completed, the officer will review your admissibility to Canada. Providing there are no concerns, the decision on your admissibility may closely follow the decision on your eligibility. However, complex medical conditions, criminal records or security concerns can significantly extend the processing time of your application. Certain reviews or verifications are conducted by partner agencies and these verifications will most likely extend the processing time of your application.
Once these reviews are completed, your application should be ready for final decision."
