Your Canadian immigration consultant has just told you that your ACRO police certificate needs an apostille before it can be submitted with your work permit application - and you have three weeks before the deadline. You have the ACRO certificate in hand, but you are not entirely sure what happens next, whether the document is even eligible for apostille in its current form, or how long the whole process will take. This is one of the most common scenarios we handle at NextDay Apostille, and the details matter more than you might expect.
Why Canada Requires an Apostilled ACRO Certificate
Canada joined the Hague Apostille Convention in January 2024, which fundamentally changed how UK-issued documents are accepted there. Before that date, Canadian authorities required consular legalisation through the Canadian High Commission - a slower, more expensive, multi-step process. Now, an apostille issued by the UK Foreign, Commonwealth and Development Office (FCDO) is sufficient to authenticate your documents for use in Canada.
For work permit applications, Immigration, Refugees and Citizenship Canada (IRCC) routinely asks applicants to provide a police clearance certificate from every country where they have lived for six months or more. If you have lived in the UK, that means obtaining an ACRO Police Certificate. But the certificate on its own is not enough. Canadian authorities want proof that it is a genuine UK government-issued document, and the apostille provides that proof.
The ACRO Certificate Itself: Getting It Right First
Before you even think about the apostille, you need to make sure your ACRO certificate is correct and current. Here are the key points:
- Processing time: ACRO currently quotes approximately 40 calendar days for standard applications, though it can sometimes arrive sooner. If you are working to a tight immigration deadline, factor this in before anything else.
- Certificate type: Make sure you apply for an International Criminal Record Check (ICRC) through ACRO, not a basic DBS check. The DBS check is a different document issued by a different body, and while it can also be apostilled, Canadian immigration specifically expects the ACRO police certificate for overseas applications.
- Validity period: Most Canadian immigration streams expect the police certificate to be no older than six months at the time of submission. If your ACRO certificate is approaching that limit, getting the apostille done quickly becomes critical.
One common mistake we see is applicants requesting a Subject Access Request from ACRO instead of the ICRC. These are different products. The Subject Access Request is not the document that immigration authorities are looking for, and the FCDO will still apostille it - they authenticate the signature, not the content - but it may be rejected by the Canadian end.
How the Apostille Process Works for ACRO Certificates
The good news is that ACRO certificates are one of the more straightforward documents to apostille. Because the certificate is issued and signed by ACRO (a public authority operating under the National Police Chiefs' Council), it does not need to be notarised first. The FCDO can authenticate the signature directly.
This is an important distinction. Many UK documents - such as degree certificates from universities or personal statements - need to be certified by a solicitor or notary public before the FCDO will touch them. The ACRO certificate skips that step, which saves both time and money.
The FCDO offers two service levels:
- Standard service: Currently takes around four to six weeks by post. Given that your ACRO certificate has a six-month validity window, this can eat dangerously into your timeline.
- Premium service: Available in person at the FCDO's Milton Keynes office, with same-day or next-day turnaround. This is the option most people with immigration deadlines choose, but it requires either attending in person or using a legalisation agent to attend on your behalf.
The Timing Trap That Catches People Out
Here is where the maths gets uncomfortable. If your ACRO certificate takes 40 days to arrive and the FCDO standard service takes another 30 working days, you are looking at roughly three months from the date you apply for the ACRO check to the date you hold an apostilled certificate. If your Canadian work permit deadline is sooner than that, you have a problem.
This is precisely why most applicants with active immigration cases opt for the FCDO premium service. The turnaround drops from weeks to hours. But you need someone to physically present the document at the Milton Keynes office during operating hours, which is not always practical if you are living abroad or based far from Milton Keynes.
When the Document Comes Back: What to Check
Once the apostille is attached, take a moment to verify the details. The apostille will be a separate page stapled or otherwise affixed to your ACRO certificate. Check that the name on the apostille matches the name on the certificate, that the date is correct, and that it references the right document. Errors are rare with the FCDO, but they do happen, and discovering a mistake after you have submitted your Canadian application is far worse than catching it beforehand.
Also keep in mind that some Canadian immigration consultants or employers may ask for a certified translation if any part of the apostille or certificate is not in English or French. Since both documents will be in English, this is unlikely to be an issue, but it is worth confirming with whoever is handling your Canadian application.
If you are working to a deadline and want to avoid the risk of postal delays, processing errors, or simply running out of time, NextDay Apostille can handle the entire FCDO submission on your behalf - including the premium same-day service. You send us the document, and we return it fully apostilled, typically within 24 to 48 hours of receipt. You can find out more at nextdayapostille.co.uk.
