The top 11 mistakes that can derail a proof of…

Americans who now qualify for Canadian citizenship by descent face a dozen common pitfalls that can sink their proof-of-citizenship applications, according to a Toronto immigration lawyer who processes these cases daily. The warning comes as processing times stretch to 12 months and even minor errors trigger automatic rejections, forcing applicants to restart from scratch.

Since December 15, 2025, Americans born before that date with at least one Canadian ancestor gained the right to claim citizenship — but exercising that right requires navigating a document-heavy application process with zero tolerance for mistakes. As reported by CIC News, Ala Bujac of Cohen Immigration Law identified eleven errors that routinely derail applications submitted to Immigration, Refugees and Citizenship Canada.

The single most common mistake: non-compliant photos. IRCC requires two identical colour printed photographs taken within the last 12 months, featuring a white or light-coloured background and specific dimensions. Each photo must carry the photographer's stamp on the back, along with the date taken and the applicant's name. U.S. passport photos, selfies, and cropped images all fail the standard. Submitting the wrong photo format guarantees rejection.

"A failure to conform to photo specifications is the single most common mistake," Bujac said.

Black-and-white photocopies of supporting documents trigger automatic rejection as well. IRCC demands colour copies of all birth certificates, marriage certificates, and citizenship documents that establish the applicant's continuous line of descent from a Canadian citizen. Missing even one document in the chain — such as a marriage certificate explaining a name change between generations — ends the application. Quebec birth or marriage certificates issued before 1994 are not accepted, a detail that catches many applicants off guard.

The application affects Americans with Canadian parents, grandparents, or more distant ancestors who can prove an unbroken citizenship line. Those born in the United States to a Canadian parent, or with a Canadian grandparent whose own parent was born in Canada, fall into the eligible group. The proof-of-citizenship certificate is required to obtain a Canadian passport as a dual citizen.

Applicants should review the Government of Canada's published photo specifications before visiting a photographer, ensure all document copies are in colour, and write "N/A" in any field that does not apply rather than leaving it blank. The application requires a signature in black ink, and the processing fee must be paid online in advance — proof of payment must accompany the mailed application. Double-checking these details before mailing the package to IRCC can prevent a year-long delay.
