What happens when IRCC returns your application
IRCC does not finish reviewing the file once it spots a fatal error. They stop, package the documents back, and mail them to you with a return letter listing the reason. The C$75 government fee is generally not refunded for fixable returns. The time you waited in queue does not transfer to the corrected resubmission. You start over from intake.
That means: a single missing signature can cost you an extra 12 months. Every mistake on this list is preventable in 60 seconds of QA before submission. We make a separate pass on each one.
Mistake 1
Citizenship photos that are passport photos
Why it happens
IRCC explicitly states that citizenship photos do NOT use passport-photo specifications. Yet most applicants walk into a UPS Store, ask for passport photos, and submit those.
What to do instead
Citizenship photos are 50mm × 70mm — taller than the 50mm × 50mm passport photo. They must be no more than 12 months old, taken against a plain background, and the photographer must write the studio name and date on the back. The applicant signs the back as well.
Ask explicitly for “Canadian citizenship photos” — not passport photos. If the photographer doesn’t know the difference, find a different one. The mismatch is the single most common return trigger.
Mistake 2
Short-form (or hospital) birth certificates
Why it happens
In several US states (Connecticut, parts of Pennsylvania, others), the standard birth certificate issued at the hospital or as a small wallet card doesn't list both parents. IRCC needs to see parents’ names to verify your chain.
What to do instead
Order the long-form (sometimes called “full certified” or “detailed”) version from your state’s Department of Vital Records. Decorative hospital keepsake certificates are not accepted under any circumstances.
If your state’s long-form still doesn’t list both parents — the 1970s Connecticut problem — you’ll need an affidavit and supporting documents (school records, census, an affidavit from a surviving parent). This is exactly the kind of weak link we surface during intake.
Mistake 3
Pre-1994 Quebec documents submitted as-is
Why it happens
Quebec did not issue secular birth certificates until 1994. Births before that were recorded in parish registers. IRCC does not accept the parish record itself, but does accept a post-1994 certified copy issued by the Directeur de l’état civil (DEC) or BAnQ.
What to do instead
Request a certified copy from DEC (for records with civil-registry data) or BAnQ (for older records, particularly those more than 100 years old). The certificate is issued in the modern format with a post-1994 date stamp — that is the document IRCC accepts.
The birth itself can be from any year. Only the certificate copy needs to be post-1994. New England applicants with Quebec roots: BAnQ saw a 3,000% spike in requests in January 2026 alone — order early.
Mistake 4
Missing marriage certificates in the name chain
Why it happens
If any person between you and your Canadian ancestor changed their name — most commonly your grandmother, mother, or you upon marriage — IRCC needs the marriage certificate to bridge the names.
What to do instead
Map the chain on paper. Every name change, every spelling variant, every order swap (common in francophone families) needs a paper bridge: a marriage certificate, a legal name-change document, or an affidavit explaining the variant.
The common pattern: your grandmother’s birth certificate says “Mary Sullivan,” her marriage certificate says “Mary Sullivan” on one side and “Mary Jenkins” on the other, and your mother’s birth certificate lists her mother as “Mary Jenkins.” That marriage certificate is the bridge. Without it, IRCC sees three different people.
Mistake 5
Forgetting to sign the application form
Why it happens
The CIT 0001 form is typically filled digitally, then printed. Applicants forget to physically sign before scanning or mailing — the digital fields don’t cover the signature line.
What to do instead
Print the form. Sign every signature box in blue or black ink. Re-scan in color. The application also requires you to sign the back of each photograph and write your name on the back of one photograph.
If you’re submitting online, the signature step is in the upload flow — do not skip it because the form is digital. Unsigned applications are returned without further review.
Mistake 6
Only one side of your ID submitted
Why it happens
Applicants often scan the front of a driver’s license or the photo page of a passport and stop. IRCC needs both sides of US IDs and both the photo and signature pages of passports.
What to do instead
For US driver’s license: scan both sides, in color. For US passport: scan the photo/biographic page and the signature page (if your passport has them on separate pages). Include the current passport — not an expired one, even if your current passport doesn’t have your maiden name.
Mistake 7
Black-and-white scans of color documents
Why it happens
The CIT 0014 checklist requires color copies of provincial vital records. Applicants who scan in B/W (or use a copier set to grayscale) get the application returned.
What to do instead
Set the scanner to color, 300dpi minimum. Even if the underlying document is black ink on white paper, IRCC needs a color scan — the seals, stamps, and signatures need to be visible in their actual color.
Pro tip: place the document on a slightly colored or off-white background when photographing with your phone. It helps IRCC’s review system distinguish the document edges from the background.
Mistake 8
1970s US birth certificates that don’t list parents
Why it happens
Some US states — Connecticut most famously, but also some Pennsylvania and Massachusetts certificates from the 1970s — issued state-level birth certificates that omitted the parents’ names. If yours is one of these, the document doesn’t prove the chain link IRCC needs.
What to do instead
Order both the standard and the long-form / detailed versions from your state. If neither shows your parents, you will need supplementary evidence: hospital records, baptismal records, school enrollment forms, US Social Security application (SS-5), or an affidavit from your parent.
Include all of it with a cover letter explaining the gap. IRCC accepts the alternate-document approach when the limitation is structural to the issuing state. The cover letter is essential — without it, your file looks like a gap, not a known issue.
We catch all eight before submission
Heritage Passport includes a return-prevention QA pass on every application we send out. Photos, signatures, ID coverage, name chain, weak certificates, color-scan compliance, alternate documents where US states fall short. The C$75 you spent on the IRCC fee is too much to lose to a fixable mistake, and the 12 months you’d wait for the resubmission queue is too much to lose to anything.
