2 File management
IRCC will manage the inventory in a manner which minimizes the expiry of key requirements — such as passports and medicals — during processing.
In addition, while considering medical and passport expiry dates, the Department will process applications without missing documentation ahead of incomplete applications (e.g., files missing police certificate or civil documentation). This means that applications of clients who have submitted all of the documentation on the IRCC checklist with their application will be prioritized for processing.
To ensure that all other applicants have an opportunity to update their application with documentation which is still needed to make a decision, the Department will send out an email to each principal applicant in the targeted inventory asking them to submit, within 60 days of the date of the email,
- any missing civil documentation;
- any missing police certificates;
- proof that they hold a passport with at least 6 months of remaining validity;
- any missing documentation for dependants, including custody documents;
- if the applicant resides in Quebec, a Quebec Selection Certificate;
- a copy of the receipt for the right of permanent residence fee, if not already paid.
For applications where items on the Document Checklist are missing, the Centralized Processing Region (CPR) will prioritize applications based on how quickly applicants respond to requests for missing documentation, such as police certificates and outstanding civil documentation.
