Bill C-3’s 1,095-Day Rule: Proving a Canadian Parent’s Physical Presence
The 1,095-day rule is the part of Bill C-3 most likely to decide new citizenship-by-descent cases—but only a defined group of families need it. It is not a new requirement for every person with a Canadian parent, and it is not a rough “three years in Canada” estimate. It is a cumulative physical-presence test that must be supported by evidence.
This article explains how the rule works in practical terms. For the broader eligibility framework, start with our Bill C-3 citizenship by descent service page.
Who needs to meet the 1,095-day test?
The rule applies to certain people born or adopted outside Canada on or after December 15, 2025, in the second generation or later. In the usual example, the child is born abroad to a Canadian parent who was also born or adopted abroad to a Canadian citizen. The parent who transmits citizenship must have been physically present in Canada for at least 1,095 cumulative days before the child’s birth or adoption.
The date matters. Many people born abroad before December 15, 2025 may have become Canadian automatically under Bill C-3 without this new physical-presence requirement. The family timeline must therefore be mapped before anyone starts compiling travel records.
“Cumulative” means the days do not have to be consecutive
There is no requirement that the parent spend three uninterrupted years in Canada. Separate periods can add together. However, every claimed day must fall before the relevant birth or adoption, and the calculation should be based on actual presence in Canada—not a mailing address, a Canadian employer, citizenship status, or a general connection to the country.
Think of the analysis as a dated ledger. Each entry should show when the parent entered Canada, when they left, what independent record supports the period, and the running total. A clean ledger exposes gaps early and avoids an unsupported total at the end.
Start with a travel and residence chronology
Before collecting documents, build a timeline from the earliest relevant date to the child’s birth or adoption. Include all known entries and exits, studies, jobs, addresses, and significant periods abroad. Then compare that timeline against documentary records.
Useful evidence can include:
- current and expired passports, visas, and entry or exit stamps;
- border-travel records where available;
- school enrolment, transcripts, and attendance records;
- employment records, pay statements, and records of employment;
- income-tax filings and notices of assessment;
- residential leases, utility bills, and health-care or other provincial records; and
- other contemporaneous records that identify the parent, date, and Canadian location.
No single record type is ideal in every case. A passport shows travel but may not account for every crossing. A tax return may support Canadian ties but not prove physical presence on each date. The stronger approach is to use overlapping records so the chronology is independently corroborated.
Do not make the days fit the answer you want
This is where otherwise promising files become vulnerable. If a parent had an extended period abroad, record it. If a passport is missing, say so and look for official replacement evidence. If dates differ between records, reconcile them with an explanation. A calculation that ignores uncertainty is not persuasive just because it reaches 1,095.
In many files, the issue is not whether there are enough days in total. It is whether the evidence actually proves the claimed days. Organizing records by time period and noting what each document proves makes the application easier to review and more difficult to misunderstand.
Prepare before the birth or adoption where possible
For Canadian citizens who were themselves born abroad and expect to have or adopt a child abroad, recordkeeping should begin now. Keep passports, travel itineraries, school and work records, and proof of residence in a secure and searchable file. Reconstruction years later is possible, but it is slower and often incomplete.
Citizenship certificate, then passport
After the child is born or adopted, the application is still a citizenship-certificate or direct-grant process, depending on the facts. The 1,095-day evidence is one part of the proof. IRCC’s current guidance is to secure proof of citizenship before applying for a Canadian passport and before travel.
Where a family history is complex or the total is close to 1,095 days, book a consultation before filing. This article is general legal information and not legal advice.
