Who the proof reaches

A narrower group than it may seem. Everyone born before December 15, 2025 is out, so are certificate replacements, and so are children of a parent who was born in Canada or naturalized before the birth. The proof targets one precise case: a child born abroad to a Canadian who was also born abroad, or who obtained citizenship as an adopted person under section 5.1. There, the parent must show 1,095 cumulative days, not continuous, of physical presence in Canada before the birth. The count is declared on form CIT 0555; the guide carries a dedicated appendix, Appendix F, with the full table of cases.

Which documents IRCC accepts

Clear, easy to read colour copies of authentic documents: employment or educational records such as T-4 slips or school transcripts, travel records such as passports or entry and exit records, rental, mortgage or insurance records, Canadian government documents at any level, and affidavits from organizations or third parties with knowledge of the parent’s presence in Canada. Every affidavit must carry the affiant’s name, mailing address and email or phone, because IRCC reserves the right to contact them to verify.

The limit is on who may swear one: not the applicant and not their family. The guide expressly excludes parents, siblings, spouse, grandparents, children, aunts and uncles, nieces and nephews and first cousins, even if that relative is a lawyer or notary. The natural witnesses of a family’s life do not count; the affidavit has to come from outside the circle.

If a record no longer exists, the applicant must explain in writing why and show they tried to obtain it, for instance with the issuing authority’s reply. And an application cannot rest solely on third party records.

What to watch now

The 1,095 days are measured at the moment of birth: they cannot be completed afterwards. A Canadian family in Latin America expecting a child and hoping to pass on citizenship needs to run the count beforehand, and start gathering the papers that time erases, passport stamps, work records, housing contracts. If the proof falls short, the guide itself points to the exits: permanent residence and later naturalization, or a grant on the basis of statelessness.
