Shipping Your CIT 0001 to IRCC: Address, Couriers, and What to Include

The mailing address for a CIT 0001 citizenship certificate application is:

That address goes on your outer envelope. What goes inside it, and how you get it there with a tracking number, is what this guide covers.

All paper citizenship certificate applications (CIT 0001) go to IRCC's Case Processing Centre in Sydney, Nova Scotia. There is only one mailing address for proof of citizenship submissions: P.O. Box 10000, Sydney, NS B1P 7C1.

Do not send your application to an IRCC local office, the Ottawa headquarters, or a Canadian consulate. Those addresses do not accept citizenship certificate applications. Sydney is the only receiving point for paper submissions.

Always confirm the current address at canada.ca before mailing. IRCC occasionally updates P.O. Box numbers, and a package sent to a closed box is effectively lost.

Before covering shipping options, it is worth knowing that paper mail is not the only submission route. IRCC has an online portal where most applicants can upload documents and submit digitally. Online submissions process about 2 to 3 months faster than paper applications, partly because the clock starts when you click submit rather than when a physical package clears Sydney's mailroom.

If your situation is straightforward, the online route is worth considering. Paper tends to be necessary for very complex chains involving pre-civil registration records or an unusually large document set.

As of July 2026, processing time for new applications is approximately 19 months, with nearly 100,000 applications in the queue. Both routes feed the same queue; online just reaches it faster.

Not all USPS international services to Canada include tracking. For an immigration document package you cannot afford to lose, you need a tracking number. A common mistake is buying a USPS Priority Mail International flat-rate padded envelope at the post office. These do not include USPS tracking. A document you mailed two months ago with no tracking number and no delivery confirmation is a document you cannot confirm arrived.

USPS services that include end-to-end tracking to Canada:

USPS Priority Mail Express International (PMEI): Delivery in 3 to 5 business days to Nova Scotia. Flat-rate envelope starts at approximately $62.70 retail. Includes full tracking. This is the right choice if you want the cheapest tracked flat-envelope option through USPS.

USPS First Class Package International: Starts around $19.40 retail for packages under 8 oz and includes tracking. The catch: this is a package service, not a flat envelope service. Your documents need to go in a rigid mailer or small box, not a standard flat envelope.

PirateShip (pirateship.com) is a free web tool that gives you commercial USPS pricing without a contract. For Priority Mail Express International, PirateShip rates run noticeably below post office retail. You print a label at home and drop the package at any USPS location. If you are shipping via USPS, using PirateShip saves several dollars at no cost.

Both carriers handle documents to Canada reliably with full tracking included on every service level.

UPS Worldwide Standard: Economy ground option, typically 5 or more business days to Nova Scotia. A document envelope runs approximately $20 to $35 depending on weight and origin zip code.

UPS Worldwide Saver or Worldwide Express: 1 to 3 business days, guaranteed delivery date, full tracking. More expensive but with a firmer arrival window.

FedEx International Priority: 1 to 3 business days, full tracking. A document envelope to Sydney typically runs $40 to $65 retail.

FedEx International Ground: Available to Canada, generally 4 to 7 business days. Less expensive than Priority, still fully tracked.

Both UPS and FedEx provide proof-of-delivery confirmation in addition to tracking. That confirmation is the evidence you would need if the package were lost and you had to demonstrate delivery to IRCC.

Use a standard 9x12 inch manila envelope or a rigid cardboard mailer. Do not fold your documents. Birth certificates, marriage certificates, and photos submitted flat arrive in better condition and are easier for IRCC officers to review.

What goes inside the envelope, in order from top to bottom:

1. Completed CIT 0001 form
2. Printed IRCC fee payment receipt (the $75 CAD online confirmation from IRCC's website)
3. Two citizenship photos (50mm x 70mm), clipped to the front of the form, signed and dated by the photographer on the back
4. Colour photocopy of your government photo ID
5. Colour photocopy of your birth certificate
6. Colour photocopies of every other birth and marriage certificate in your ancestry chain
7. Alternative evidence documents (census records, church records) if applicable
8. A brief cover letter explaining your ancestry chain, optional but useful for complex cases

Send colour photocopies, not originals. IRCC does not return original documents in most cases. Your original certified birth certificates stay at home. What goes in the envelope is colour photocopies of those certified originals. Black-and-white copies are rejected. If you are scanning to print, scan at 300 DPI or higher so security features and stamps reproduce clearly.

Families sometimes submit applications for multiple people at the same time. IRCC allows you to send all family packages in a single outer envelope, but each applicant's complete document set, including their own payment receipt, must be separately organized inside. Clip or rubber-band each person's stack separately and label each set with the applicant's name. One payment receipt cannot cover two applicants.

Record the tracking number and the date you mailed the package. IRCC sends a paper acknowledgment of receipt roughly 4 to 8 weeks after the application arrives in Sydney.

The processing clock starts when IRCC receives the package, not when you mail it. Transit time from the US to Sydney is not processing time. USPS Priority Mail Express International takes 3 to 5 business days; UPS and FedEx typically arrive in 1 to 3 business days.

Check the tracking once delivery is confirmed, then stop. Contacting IRCC before the posted processing window has passed does not move your application forward. Keep a complete photocopy set of everything you mailed so you can respond quickly if IRCC sends a request for additional information.

MaplePass reviews your document package before you mail and flags issues that would cause a return. A completeness check before you seal the envelope is faster than waiting for a returned package in a 19-month queue.
