AOR in Express Entry: What the Acknowledgment of Receipt Means, When It Arrives and Why the Date Matters (Real Cases)
One short letter in your account starts three clocks at once. Here is what the acknowledgment of receipt is, what it proves, and what applicants got wrong about it.
The AOR in Express Entry is the first thing IRCC sends back after you submit your permanent residence application. AOR stands for acknowledgment of receipt. It is a short letter, it usually lands in your account without ceremony, and for the next six months it is the most quoted date in your file.
People count everything from it. Forum signatures list “AOR: March 3” before anything else. Work permit plans hang on it. Parents of a 21-year-old watch for it. And yet IRCC’s public pages say surprisingly little about the letter itself, which is why so much of what applicants believe about it comes from other applicants.
We read five IRCC pages that mention the acknowledgment of receipt, the completeness check and the dates that follow from them, and four public forum threads from 2015 to 2026. Where the official pages are silent, for example on how fast the letter should arrive, we tell you what applicants reported and label it as that.
Quick answer: what is the AOR in Express Entry?
It is the letter IRCC sends to your account after it receives your permanent residence application. IRCC’s own glossary calls it the acknowledgement of receipt (R10 passed) letter, issued once the application has passed the completeness check. It carries your application number. You need a copy of it to apply for a bridging open work permit, and the date IRCC received your complete application is the date used to lock in a dependent child’s age and to start the processing time clock.
Key takeaways
What IRCC says the AOR in Express Entry is
Three official pages describe the letter, each from a slightly different angle.
IRCC’s glossary of permanent residence terms (modified August 12, 2026) gives it a formal name: the acknowledgement of receipt (R10 passed) letter. It says the letter is issued to the applicant, or their representative, once the application for permanent residence has passed the R10 completeness check. “R10” is the section of the immigration regulations that lists what a complete application must contain.
The Help Centre answer “How can I check if my application has been received?” (modified April 17, 2026) says that if IRCC starts processing your application, it sends an acknowledgement of receipt letter or email with an application number. It adds that the acknowledgement may be delayed, since it is only sent after the application is opened and checked for completeness.
The bridging open work permit page (modified June 23, 2026) describes it from the applicant’s side: IRCC sends this letter to your account after it gets your permanent residence application.

AOR and “passed the completeness check”: one event or two?
Applicants often talk about these as separate milestones: first the AOR, then, some time later, a completeness check. IRCC’s glossary ties them together. By its definition the acknowledgement of receipt letter is the one issued when the completeness check has been passed.
In practice, forum members describe an automatic confirmation right after payment and a letter in the account shortly afterwards, and they call both “AOR”. We cannot tell from the public pages whether today’s Express Entry system always performs the full check before the letter is generated. What is certain is the other direction: if an application fails the check, IRCC’s “After you apply” page says it is rejected and the processing fee refunded. We go through that outcome in application rejected as incomplete.
Save the letter the day it arrives
Download the acknowledgment of receipt as a PDF and keep it with your payment receipt and a copy of the submitted application. You will need it for a bridging open work permit, and it is the quickest way to find your application number when you fill in an IRCC web form.
When the AOR arrives, according to applicants
IRCC gives no timeline, so this section is applicant experience only.
Real case: 36 hours and no letter (August 2017)
An applicant who had just submitted saw the status change to “submitted” but had no acknowledgment by email or in the account, and asked whether it might come by post. A member replied that their own acknowledgment email and account message had arrived 24 hours after submitting. By the next day, more than 36 hours in, the poster was getting worried and asked what could be causing the delay. No resolution was reported in the thread.
Real case: acknowledgment one day, medical passed the next (November 2015)
In a thread collecting fast timelines, one applicant listed an acknowledgment on October 14 and a “medical passed” update on October 15, followed by a request for a background form four days later and a passport request the week after. It is a self-reported timeline from almost a decade ago, but it shows the letter arriving at the very start, before any other update.
So “about a day” is the common report, and a slightly longer wait is not unusual. That fits IRCC’s own caution that the acknowledgment may be delayed.
Why the date of the AOR in Express Entry matters: three clocks
The reason applicants care so much is that the date your complete application reached IRCC is used in at least three places.
1. Processing time
IRCC’s Help Centre says your processing time starts the day it receives your complete application, which for an online application is the day you submit. For most people that is the same day as, or the day before, the date on the acknowledgment. Six months is the standard for 80% of files, and it is counted from there.
2. A dependent child’s age
IRCC’s page on the age limit for dependent children (modified July 3, 2025) says children qualify as dependants if they are under 22 and do not have a spouse or partner. For the Federal Skilled Worker Program, Federal Skilled Trades Program and Canadian Experience Class, it says the lock-in date is the date IRCC gets your complete application for permanent residence. A child who is 21 on that date is assessed as 21, even if they turn 22 during processing. The child still has to remain without a spouse or partner.
If you have a child close to that birthday, this is the strongest reason not to use all of your Express Entry ITA deadline. Submitting a complete application two weeks earlier can decide whether they are on the file.
3. A bridging open work permit
For applicants working in Canada, the letter is a key. IRCC’s bridging open work permit page says you must be the principal applicant on the permanent residence application, must have submitted a complete application and passed the completeness check, and must include a copy of your acknowledgement of receipt letter. The page lists the Federal Skilled Worker Program, Canadian Experience Class, Federal Skilled Trades Program and Provincial Nominee Program among the qualifying programs. A later post in this series covers that permit in full; our overview of TR to PR pathways explains where it fits.
Real case: bridging permit application sent without the AOR (March 2019)
A worker whose permit was about to expire had submitted a permanent residence application in December 2018 and received the acknowledgment within 24 hours. Days before the permit ran out in February 2019, they applied for a bridging open work permit but forgot to attach the letter. A member advised sending it through the IRCC web form straight away. Another person in the thread said they had sent their own acknowledgment about two months after applying for the bridging permit and were approved a few days later. The original poster’s result was not reported.
What to do if no AOR arrives
There is no official number of days after which silence becomes a problem. Based on IRCC’s Help Centre and the threads, this is the order we would follow.
Our suggested order
If you need the letter urgently for a work permit, say so in the web form and attach the proof of submission you do have.
After the AOR: what comes next
The letter is the starting line. IRCC’s “After you apply” page (modified August 4, 2026) says that if the application is complete, it sends a letter asking for biometrics, and you have 30 days from the date on that letter. The medical exam results are reviewed, background checks run, and IRCC may ask for more documents along the way.
Real case: AOR received, but the profile still said “update not submitted” (August 2026)
An applicant corrected one answer in the application after being invited, changing a job offer field from yes to no, which did not affect their score. After submitting and receiving the acknowledgment, they noticed their Express Entry profile still showed an update as not submitted and worried something had gone wrong. A member explained that once the permanent residence application is submitted, the profile no longer matters. What counts is what is in the submitted application. The poster was satisfied with that answer.
That is a useful way to think about it. Before the acknowledgment, your profile is the thing IRCC looks at. After it, the application is. Anything that changes from then on is reported to IRCC directly, not by editing the profile.

The day your AOR arrives
The acknowledgment does not change your points and it does not mean approval. It means you are in the queue with a complete file. If you are still waiting for an invitation, the number to watch is your score: check it with the CRS calculator against the latest draw cut-offs.
Frequently Asked Questions
What does AOR in Express Entry mean?
AOR is the acknowledgment of receipt. IRCC’s glossary calls it the acknowledgement of receipt (R10 passed) letter and says it is issued once a permanent residence application has passed the completeness check. It includes your application number.
How long after submitting do you get the AOR?
IRCC does not publish a time. Its Help Centre says the acknowledgment may be delayed because it is sent only after the application is opened and checked for completeness. Applicants on public forums commonly reported receiving it about 24 hours after submitting.
Does the AOR mean my application is complete?
By IRCC’s glossary definition, the letter is issued once the application has passed the completeness check. It does not mean the application is approved, and IRCC can still ask for more documents later.
Do I need the AOR for a bridging open work permit?
Yes. IRCC’s bridging open work permit page says you must have submitted a complete application, passed the completeness check, and include a copy of your acknowledgement of receipt letter.
Is my child’s age locked in on the AOR date?
For the Federal Skilled Worker Program, Federal Skilled Trades Program and Canadian Experience Class, IRCC says the lock-in date is the date it gets your complete application for permanent residence. A child must be under 22 on that date and have no spouse or partner.
What if I never get an AOR?
First confirm in your account that the application shows as submitted and that you have a payment receipt. Check the account messages, not only email. If nothing arrives after a few days, ask through the IRCC web form with your submission date and receipt number.
Not at the AOR stage yet? Start with your score
The acknowledgment only comes after an invitation and a complete application. See where your points stand against recent draws.
Final Thoughts
The AOR in Express Entry is a small letter with a long reach. It confirms IRCC has a complete application, gives you the number you will quote for months, and fixes the date that processing time, a child’s age and a bridging work permit all depend on. Save it, note the date, and get on with biometrics.
If a child is close to 22, if your work permit expires within weeks of applying, or if no acknowledgment has arrived and your status in Canada depends on it, speak to a licensed consultant or lawyer. Those are the cases where a few days either side of the AOR date change the outcome.
