Acknowledgement of Receipt or AOR is a document issued by Immigration, Refugees and Citizenship Canada (IRCC) as a confirmation that your application has been received and is now being processed.
No matter whether you are applying through Express Entry, family sponsorship, or other immigration streams, receiving the AOR is a key milestone showing that your application has entered the processing queue.
The AOR includes a date and a unique application number. The date is your official submission date, and the unique number allows you to track your application status.
The AOR is often considered the lock-in date for your application. This means that your age, dependents, and other eligibility factors are assessed as they were on the date you received the AOR, not later during the process. However, under certain circumstances, you may be able to update your profile.
How Long Does it Take to Receive an AOR
The time it takes to receive an AOR depends on how you applied and the type of application. According to IRCC, the time can be varied from a few days to several months. For online applications (usually used for Express Entry, PR Sponsorship, etc.), you will receive your AOR instantly or within a few minutes.
However, the time can be significantly longer, typically about 4-8 weeks for paper-based applications. This time can vary depending on where you are applying from, the total number of applications, and the completeness of your application.
Paper-based applications vs electronic applications
Paper applications and electronic applications follow similar steps, but their timelines can differ. Electronic submissions are often faster because they are received and processed immediately by Immigration, Refugees and Citizenship Canada (IRCC). Paper applications, on the other hand, can take longer to reach processing centers, and additional time may be needed for scanning or manual handling. While both methods are valid, choosing electronic submission can sometimes lead to quicker updates on your application’s progress.
Does receiving an AOR mean my application is complete?
Getting your AOR simply confirms that IRCC has received your application. It does not mean your file is complete or that all documents are accepted. After this acknowledgment, officers may request additional information or documents to verify your eligibility. Responding to these requests promptly is important, as delays could extend your processing time. Think of the AOR as the first checkpoint—your application is officially in the system, but several steps remain before a final decision is made.
What Should I Do After Receiving AOR?
First, save your AOR. It includes an AOR date and an application number, which you will need to track your status or communicate with IRCC. Make sure your contact info is up to date and check your Email for any updates or requests.
Also, check your IRCC online account for updates or requests. You may be asked to submit biometrics or complete a medical exam. Follow the instructions and provide the required documents.
Finally, set realistic expectations and be patient. It may take several months, sometimes over a year for your application to be processed. You can use IRCC’s processing time tools for an estimation, but real timelines can vary depending on the number of applicants and the type of your application.
