Moreover, in the blog they are mentioning that ELIGIBILITY is the next step, while it has been proven so far that many applications are getting their security and criminality cleared before ELIGIBILITY so whether it is a hirarchial process or not is also not very apparent.
Most applications will follow the following sequence:
1. R10
2. Medicals
3. Criminality (usually happens with R10)
4. Eligibility
5. Security
If an application is found to be incomplete, it will be rejected, and there is not need to go forward. Also, when an application is incomplete, there I no need to provide a Procedural Fairness Letter (PFL). This is why R10 is the first step.
The criminality is based on PCC, but if your are an inland applicant, and you have not submitted RCMP PCC, your criminality will be the last thing. By this time, the medicals too are cleared by health Canada. Not it makes sense, that if any applicant or his family member is inadmissible for medical reason or criminality, the process will stop and the refusal letter will be given.
If by this time everything is on track, eligibility will start. This is the most time consuming and human resource intensive stage. Each document is read, reviewed, analysed, compared with your profile and a match with eh score is done. Eligibility takes place in 2 stage. First an analyst or program assistant will review, and make a note in the GCMS. Then this is reviewed by an officer, who makes a final determination. In the analysts / assistant's notes he may flag certain documents as "review required." This by itself does not mean an issue, rather it flags that specific point or the document for an officer to have a closer look before making a final decision on eligibility.
Only after eligibility is passed, will the security commence. This is because, eligibility is entered with IRCC, whereas in security not only other federal agencies like CBSA, CSIS and RCMP participate; other countries and foreign agencies are also looped in on case by case basis. So if the eligibility is not passed, there is no point to go through this process.
Hope this makes sense.
