Canada’s recent citizenship by descent changes have led to growing interest in proof of citizenship applications, particularly from people with Canadian parents or grandparents born abroad.
But applicants hoping to secure a Canadian citizenship certificate need to ensure their application meets Immigration, Refugees and Citizenship Canada (IRCC) minimum requirements before submission.
If key elements are missing, the application can be rejected as incomplete.
The issue has become more important following changes under Bill C-3, which removed the first-generation limit for many citizenship by descent cases and opened eligibility to thousands more applicants worldwide.
Many of those claims involve historical records, overseas documents and complex family histories, increasing the risk of incomplete submissions.
Why Completeness Matters
IRCC requires all proof of citizenship applications to go through a completeness check before processing begins.
The department says applications must contain certain minimum legal requirements to be accepted into processing.
If those elements are missing, IRCC will reject the application and return it with a notice explaining what is missing.
No further processing will take place until a new, complete application is submitted.
Could You Be a Canadian Citizen by Descent?
Bill C-3 has opened Canadian citizenship to thousands of people with a Canadian parent or grandparent born abroad. Find out in minutes whether you qualify.
Minimum Requirements For A Citizenship Certificate Application
IRCC says a proof of citizenship application must include the following core elements:
- A completed CIT 0001 application form
- Required signatures
- Photographs that meet IRCC specifications
- Proof of payment for the $75 fee
Applications missing any of these items risk immediate rejection.
Common Reasons Applications Are Rejected
Missing Or Incomplete CIT 0001 Form
Applicants must submit the most recent version of the CIT 0001 Application for a Citizenship Certificate.
All required sections must be completed clearly and accurately.
Missing information may prevent officers from assessing the application properly.
Missing Signatures
Applications must include all required signatures.
This includes:
- Applicants aged 14 or older
- Parents or guardians for minors
- Authorized representatives where applicable
Paper applications must also be signed and dated in ink.
Incorrect Or Missing Photographs
Photographs must meet IRCC’s official specifications.
Applications can be rejected if photos are missing, outdated or fail to meet required standards.
Missing Proof Of Payment
Applicants must provide proof they paid the $75 citizenship certificate fee in full.
Failure to include the payment receipt can result in rejection.
What Else Should Applicants Include?
In addition to the minimum requirements, applicants should include all supporting documents relevant to their citizenship claim.
Depending on the case, this may include:
- Government-issued photo identification
- Birth certificates
- Citizenship certificates of parents or grandparents
- Name change documents
- Historical civil records
Citizenship by descent applications often rely on records from multiple countries and generations, making careful preparation especially important.
More Flexibility For Some Missing Documents
IRCC says officers may still accept applications missing non-essential supporting documents and request them later during processing.
This flexibility is particularly important for applicants outside Canada and the United States because returning applications internationally can create delays and mailing issues.
However, the core legal requirements still apply in every case.
Changes For Applicants Outside Canada
Effective March 1, 2026, Global Affairs Canada reduced its role in processing proof of citizenship applications submitted outside Canada and the United States.
IRCC staff now conduct the minimum completeness checks for those applications.
The department says the goal is to improve processing efficiency while ensuring applications meet legal requirements before entering the system.
What This Means For Citizenship By Descent Applicants
The recent citizenship by descent changes are expected to continue driving higher application volumes as more people seek to confirm their Canadian status.
Applicants should carefully review every form, signature, photograph and payment receipt before submitting their file.
Even small omissions can lead to rejection and lengthy delays, especially for applicants applying from overseas.
