What changed, and who it changed things for
This is the largest change to Canadian citizenship in a generation, and its effect is retrospective. It does not open a route for people to apply through. It makes people citizens who already should have been.
Since December 2025 many people are citizens already and do not know it
The first generation limit is gone. From 2009 until 15 December 2025, a person born or adopted outside Canada was not a citizen by descent unless their Canadian parent had been born in Canada or naturalised here. A citizen by descent could not pass citizenship to a child born abroad.
If you were born outside Canada before 15 December 2025 to a Canadian parent, in the second generation or beyond, then in most cases you are automatically a citizen, which is how the department itself puts it. Nothing needs to be granted to you. What you may need is a certificate proving it, which is a separate application and is not what makes you a citizen.
The Act carries narrow exceptions to that, so the words in most cases are doing work. The main two are a person who made a declaration of alienage before 1947, or before 1949 for Newfoundland, and a person who became a citizen by a grant and later renounced it. If either could describe you or an ancestor in your chain, the answer turns on the documents rather than on the general rule.
The reach back is generational. The chain of proof can run through several generations, provided there is a parent or parental ancestor who became, or would have become, a citizen on or after 1 January 1947, or 1 April 1949 for Newfoundland. Citizenship still passes from a parent, but the documents may go back much further.
- Born abroad before 15 December 2025, second generation or beyond. You are a citizen automatically, with no test to meet. Apply for a certificate if you need to prove it or want a passport.
- Born abroad on or after 15 December 2025. You are a citizen if the Canadian parent who was themselves born or adopted abroad had 1,095 days of physical presence in Canada before your birth. Either citizen parent can satisfy it.
- Adopted abroad before 15 December 2025. You apply for a direct grant rather than becoming a citizen automatically, and no 1,095 day test applies to you.
- Adopted abroad on or after 15 December 2025. You apply for the direct grant, and the parent must meet the 1,095 days before the adoption.
- Already a citizen before the change. Nothing about your status changes.
- The department's own wording on one point is wrong, so do not rely on it. Several of its pages say the government passed the Bill on 15 December 2025. Royal assent was 20 November 2025 and 15 December 2025 is the day it came into force. The operative date for who is caught is 15 December 2025.
Which situation applies to you
| Your situation | Are you a citizen | What you do |
|---|---|---|
| Born abroad before 15 December 2025, in the second generation or beyond | Yes, automatically | Apply for a citizenship certificate as proof. No grant and no test |
| Born abroad on or after 15 December 2025, in the second generation or beyond | Only if a citizen parent had 1,095 days of presence in Canada before your birth | Apply for a certificate and prove the parent's days |
| Adopted abroad before 15 December 2025, in the second generation or beyond | Not automatically | Apply for the direct grant for adopted persons. No 1,095 day test |
| Adopted abroad on or after 15 December 2025 | Not automatically | Apply for the direct grant, and the parent must meet the 1,095 days |
| Born in the first generation abroad to a parent born or naturalised in Canada | Yes, as before the change | Apply for a certificate if you need proof |
| Already a citizen before 15 December 2025 | Yes, unchanged | Nothing |
A person born in Canada is a citizen by birth and does not use this route at all, with narrow exceptions for the children of certain foreign representatives.
The adoption asymmetry follows from the structure of the Act. A person born abroad in the second generation before December 2025 is a citizen automatically, while a person adopted abroad in the same generation and before the same date must apply for a grant. The reason is on the face of the legislation. Citizenship by descent arises automatically under section 3, whereas an adopted person has since 2007 required a grant under section 5.1, so removing the first generation limit changed who is caught by an automatic rule and left the adoption route as an application. If you were adopted abroad, that distinction decides whether you are already a citizen or an applicant, so it is worth establishing before anything is filed.
Proving a parent's 1,095 days
This only arises for a birth or adoption on or after 15 December 2025, and it is better documented than people expect. There is a form for it and there is a published list of the proof that goes with the form.
The form is How to Calculate Physical Presence in Canada for a Canadian Parent, CIT 0555. The department asks you to complete it and to provide supporting proof validating the information you declare on it. Treat it as required rather than as a helpful extra, because a file that arrives without it is incomplete, and an incomplete file is the most avoidable delay in this area.
| Category | Examples the department gives |
|---|---|
| Employment and educational records | Transcripts, T4 slips |
| Residential records | Rental, mortgage or insurance papers |
| Travel records | Passports, entry and exit records |
| Government records | Social assistance or employment insurance benefits |
| Other proof | Anything else the applicant considers demonstrates the parent's physical presence in Canada |
The list is expressed as examples and not as a closed set, in the department's own words acceptable proof may include but is not limited to these categories. The 1,095 days are cumulative rather than consecutive, there is no minimum per year, and they must fall before the birth or adoption rather than be made up afterwards.
Might you already be a citizen
This is the question worth asking first, because the answer changes what you apply for. A citizen applies for proof. A non citizen applies for a grant, or for permanent residence.
