Key facts
- IRCC’s courier intake recently moved: all citizenship streams now courier to the IRCC Digitization Centre, 3050 Wilson Ave, New Waterford NS B1H 5V8. The old Dorchester Street address in Sydney is obsolete.
- Sydney uses three different PO boxes — Citizenship Grants go to PO Box 7000 (B1P 6V6), proofs of citizenship to PO Box 10000 (B1P 7C1), and PR cards to PO Box 10020 (B1P 7C1). Mixing them up delays your file.
- IRCC recommends sending paper applications by tracked mail so you have proof of delivery, and prefers that you apply online when the option is available.
- Most adult applicants can now apply for citizenship online; the mail-in route remains available for everyone and is required for some situations.
- PostPal prints and deposits your application with Canada Post the next business day for $6 flat — newcomers without a printer can mail IRCC paperwork entirely online.
How to mail it, step by step
- 1
Complete the citizenship package
Fill out the application for your situation (adult, minor, or adopted person), sign and date it, and gather the photos, photocopies, and language evidence the document checklist requires. Pay the fee online and include the receipt.
- 2
Choose Canada Post or courier
Regular and tracked Canada Post mail goes to the Sydney PO box; private couriers must use the street address in New Waterford. Couriers cannot deliver to a PO box, so picking the right pair matters.

Common questions
Where do I mail my citizenship application in 2026?
By regular or tracked Canada Post mail, send it to the Case Processing Centre – Sydney, Citizenship Grants, P.O. Box 7000, Sydney NS B1P 6V6. If you use a private courier, send it to the IRCC Digitization Centre – Citizenship, 3050 Wilson Ave, New Waterford NS B1H 5V8 instead, because couriers cannot deliver to a PO box.
Is the Dorchester Street, Sydney courier address still valid?
No. IRCC’s courier intake moved from Dorchester Street in Sydney to the IRCC Digitization Centre at 3050 Wilson Ave, New Waterford NS B1H 5V8. Many older guides and forums still list the Sydney street address — using it risks a returned or delayed package. Regular mail still goes to the Sydney PO boxes.
Which Sydney PO box is for citizenship grants?
Citizenship grant applications go to P.O. Box 7000, Sydney NS B1P 6V6. Sydney hosts two other IRCC boxes: PO Box 10000 (B1P 7C1) for proof of citizenship applications and PO Box 10020 (B1P 7C1) for PR card applications. Each box feeds a different processing stream, so check the label before you mail.
Can I apply for citizenship online instead of by mail?
Yes — IRCC prefers online applications, and most adults applying for a grant of citizenship can use the online portal. Paper remains an option for everyone. If you paper-file but have no printer, PostPal lets you mail the whole package online: upload your PDF and we print and post it for $6.
Should I use tracked mail for my citizenship application?
IRCC recommends it. A tracking number proves your application arrived and gives you a delivery date if processing questions come up later. PostPal deposits your letter with Canada Post the next business day and emails you a dated mailing confirmation.
Do minor applications go to the same address as adult applications?
Yes. Grant applications for adults and minors both go to the Case Processing Centre – Sydney, Citizenship Grants, P.O. Box 7000, Sydney NS B1P 6V6 (or the New Waterford digitization centre by courier). Just make sure each application uses the correct form and checklist for the applicant’s age.
