The 1,095-Day Test: How to Document Your Parent’s “Substantial Connection” to Canada Under Bill C-3

Bill C-3 changed who can acquire Canadian citizenship by descent, and for many families that change is genuinely good news. If your child was born outside Canada before December 15, 2025, they may now be a Canadian citizen by operation of law if they would have been a citizen but for the former first-generation limit or certain other provisions of the Citizenship Act that were changed by Bill C-3. You still need to apply for a citizenship certificate to obtain formal proof of that citizenship, and you must provide authentic, reliable and verifiable documents establishing the relevant parent-child relationships and Canadian citizenship.

If your child was born or adopted abroad on or after December 15, 2025, and you were also born or adopted outside Canada, the law now asks something of you it never asked before in many cases: proof of your own substantial connection to Canada, measured in a specific number of days. Note that while children born abroad who acquire citizenship by descent generally apply for a citizenship certificate, people adopted abroad can apply for a direct grant of citizenship under Section 5.1 of the Citizenship Act, which is a separate process, and the applicable substantial-connection rules must be considered separately. Different exceptions can apply depending on the adoptive parent’s circumstances.

That number is 1,095, or three years added up across your lifetime before your child’s birth or, where applicable, adoption. It sounds simple until you sit down and try to actually document it, which is where most families run into trouble.

The Parliamentary Budget Officer previously estimated that substantially similar predecessor legislation, Bill C-71, could affect roughly 115,000 people over five years. That was an estimate based on the proposed legislation and the assumptions used for the PBO’s costing, not a confirmed count of people who would ultimately qualify under the enacted Bill C-3. Still, it represents a large number of families who may discover that qualifying in principle and proving it on paper are two very different tasks.

What “Substantial Connection” Actually Means Under Bill C-3

Although the legislation calls this a “substantial connection” to Canada, the relevant test is highly specific: 1,095 cumulative days of physical presence in Canada before the child’s birth or, where applicable, adoption, subject to statutory exceptions. In other words, for purposes of these Bill C-3 provisions, the substantial-connection requirement is demonstrated through the statutory physical-presence test; it is not a general test of someone’s overall ties or connection to Canada.

The substantial connection test asks whether at least one qualifying Canadian parent, who was themselves born or adopted outside Canada, accumulated at least 1,095 cumulative days of physical presence in Canada before their child was born or adopted. It generally applies to second-generation and later cases where the birth or adoption falls on or after December 15, 2025.

If you were born in Canada, or were granted Canadian citizenship through naturalization before your child’s birth or adoption, the post-Bill C-3 1,095-day requirement generally does not apply when you pass citizenship by descent to a child born abroad. An important exception applies where you became a Canadian citizen through the adoption provisions of Section 5.1 of the Citizenship Act. The test exists specifically for people who were themselves born or adopted abroad to a Canadian parent and now want to pass citizenship to a child also born or adopted abroad, where the substantial-connection rules apply.

There are important exceptions, including rules involving Canadian Crown servants and certain families with a history of Canadian government service abroad. The physical-presence requirement can be displaced in specified circumstances where the relevant Canadian parent was a qualifying Crown servant at the time of the child’s birth or, for an adopted person, when the adoption was finalized. A separate exception can apply where the Canadian parent’s own parent or adoptive parent was a qualifying Crown servant at the time of the Canadian parent’s birth or adoption. These Crown-servant provisions are exceptions to the physical-presence requirement; they should not be understood simply as converting time spent abroad into days physically present in Canada. Do not assume that the 1,095-day calculation is necessarily the rule that applies to you.

Meeting the 1,095-day threshold does not by itself establish Canadian citizenship. It is one eligibility requirement within the citizenship-by-descent rules, and the parent-child relationship, the Canadian parent’s citizenship status, the applicable generation rules and any statutory exceptions must also be established.

What is Important to Know About the 1,095-Day Count

Families almost always assume those days need to fall within a set window, something like three years within the last five, similar to how permanent residents prove they have kept up their residency obligations. But that is not how this test works.

There is no fixed five-year window. The days can be accumulated at any point during your life before your child’s birth or adoption; they do not have to be consecutive or fall within a fixed five-year period. A childhood spent partly in Toronto, a few university semesters in Vancouver, and a couple of adult years working in Calgary can all be combined into one total.

This is different from the 1,095-day physical-presence requirement that applies to many permanent residents applying to become Canadian citizens. The naturalization calculation generally looks at a five-year eligibility period. The Bill C-3 substantial-connection test does not.

This matters because it means people who assumed they were disqualified often are not. If you lived in Canada as a teenager and again briefly in your twenties, add it up before you assume the door is closed.

IRCC currently uses Form CIT 0555, “How to Calculate Physical Presence in Canada for a Canadian Parent,” to help applicants reconstruct the relevant Canadian parent’s physical presence in Canada. According to IRCC’s current document checklist, CIT 0555 is required for paper applications and does not apply to applications submitted online, although the physical-presence requirement itself still applies. The calculation looks at the parent’s history of physical presence from the parent’s date of birth through the child’s birth or adoption. CIT 0555 is the calculation form; it is not, by itself, proof of the 1,095 days. IRCC also requires documentary evidence supporting the physical-presence periods declared on the form.

The Documentation Trap: Why “I Lived There” Isn’t Proof

Knowing you spent enough time in Canada and proving it to IRCC are separate problems. Physical presence has to be demonstrated with evidence showing where you actually were on specific dates, not just where you were registered or where your family lived.

School, employment, residential, government and travel records can all help build that picture. Tax and other government records may also help corroborate the period. IRCC’s document guidance identifies a range of government, residential and other records that may help establish physical presence, and additional evidence may be requested depending on the circumstances.

For parentage and citizenship, official and other reliable documents establishing the relevant relationships and citizenship are particularly important. For physical presence, however, IRCC may also consider corroborating evidence such as affidavits from people who have personal knowledge of the parent’s presence in Canada. IRCC’s current document guidance specifically identifies third-party affidavits as one type of evidence that may help establish residence and physical presence.

The families who struggle most are the ones who lived in Canada quietly and normally, without generating much of a paper trail because nothing about it felt unusual at the time. A parent who worked under a temporary permit, or a young adult who lived with relatives without ever putting a lease in their own name, can genuinely have met the day count while having almost nothing on paper to show it.

That does not necessarily mean the case is hopeless. It means the evidence may need to be assembled from several different sources rather than relying on one perfect document covering the entire period. The usefulness and strength of any particular document will depend on the circumstances, and IRCC may request additional documentation.

What Counts as a Day in Canada (and What Doesn’t)

IRCC’s current form and application guidance provide several practical details about how physical presence is calculated. Physical presence is based on whether you were actually in Canada. Time spent outside Canada does not count toward the 1,095 days, so travel records can be important when reconstructing periods in which you lived in Canada but made trips abroad.

For this calculation, IRCC’s current CIT 0555 form asks applicants to provide the dates of entry into and departure from Canada and calculate the total number of days of physical presence. The example shown on the form counts both the day of entry and the day of departure, so a stay from June 21 to June 28 is shown as 8 days. The relevant calculation therefore depends on the actual dates of entry and departure, not simply the number of months or years someone remembers living in Canada.

What does not count is Canadian citizenship, family ties, Canadian schooling abroad or other connections to Canada without actual physical presence in Canada. Growing up in a Canadian household abroad, attending a Canadian school overseas, or holding Canadian citizenship on paper the entire time does not substitute for physical days spent inside Canada.

If your calculation is close to 1,095 days, do not rely on an informal estimate. The statutory threshold is 1,095 days, and IRCC may ask for documentation supporting the dates you declare.

An Important Exception: Crown Servants

The 1,095-day requirement does not apply in certain situations involving Canadian Crown servants. For example, the physical-presence requirement can be displaced where the Canadian parent was a qualifying Crown servant at the time of the child’s birth or, for an adopted person, when the adoption was finalized, subject to the statutory requirements and the exclusion for locally engaged employees. A separate exception can apply where the Canadian parent’s own parent or adoptive parent was a qualifying Crown servant at the time of the Canadian parent’s birth or adoption.

These rules are technical, and the timing matters. Families with a history of Canadian government or military service abroad should check the specific statutory exception before assuming that the 1,095-day calculation applies to them. The Crown-servant provisions are exceptions to the physical-presence requirement rather than a general rule that overseas service is treated as physical presence in Canada.

Real Scenarios: How This Plays Out

Consider a woman born in Seoul to a Canadian father who was himself born in Vancouver. She spent four calendar years living in Ottawa while her father worked there, then returned to Korea for the rest of her upbringing. She now lives in the United States and had a child in 2026. Her father’s Canadian birth meant she inherited citizenship automatically, without any day count of her own. Her child, however, is born on or after December 15, 2025 and the second-generation rules therefore become relevant, so her own 1,095 days matter. Four years in Ottawa could put her above that threshold, but the relevant question is the number of qualifying calendar days she was actually physically present in Canada. She would still need to document the actual period she was physically present in Canada and account for any time she spent outside Canada. Enrollment records, report cards, residential records and travel records could all help establish the calculation.

Now consider a man born in Manila to a Canadian mother who was herself born abroad in London to a Canadian grandfather. If the man was born before December 15, 2025, Bill C-3 may recognize him as a Canadian citizen despite the former first-generation limit. But if he later has a child abroad on or after December 15, 2025, the relevant question is whether he, as the Canadian parent, accumulated at least 1,095 days of physical presence in Canada before his child’s birth. His mother’s time in Canada does not satisfy that requirement for his child. The 1,095-day requirement is a test of the relevant Canadian parent’s own physical presence; days accumulated by a grandparent or earlier generation cannot simply be transferred to that parent for purposes of satisfying the requirement. He therefore needs to reconstruct his own Canadian physical-presence history. The result could be different if an exception applies, including one involving Crown service.

Frequently Asked Questions

Does the substantial connection test apply to me if I was born in Canada?

No, not generally. The post-Bill C-3 substantial-connection requirement is aimed at parents who were themselves born or adopted outside Canada. If you were born in Canada, or were granted Canadian citizenship through naturalization before your child’s birth, the 1,095-day requirement generally does not apply when you pass citizenship by descent to a child born abroad. Different rules can apply where you became a citizen through the adoption provisions of Section 5.1 of the Citizenship Act.

What if I can’t find enough documentation to prove my days?

Gather everything you can first, then talk to an immigration lawyer before assuming you are out of options. School and medical records, old leases, government records, employment records and travel documents can all help. In appropriate cases, affidavits from third parties who can credibly speak to your presence in Canada may also help corroborate periods for which other records are limited. The strength and usefulness of any particular evidence will depend on the circumstances, and IRCC may request additional documentation.

I’m a permanent resident of the US applying for my child’s citizenship. Does my status here affect anything?

No, not for the 1,095-day calculation itself. What matters is your own history of physical presence in Canada, not where you currently live or what immigration status you hold elsewhere.

Where do I find my A-number, and do I need it for this application?

An A-number is a US immigration identifier. It is not part of the Canadian citizenship-by-descent eligibility test or the 1,095-day calculation. If your case also involves US immigration matters, you may need it for those purposes, but it is not a Canadian citizenship requirement.

Can I count the time I spent in Canada as a baby or young child?

Yes. Physical presence during childhood can count toward your 1,095 days. The important issue is being able to establish the relevant physical presence with credible documentation.

How long does the whole process typically take once I apply?

Processing times can change as IRCC adjusts to application volumes and new citizenship rules. Rather than relying on a fixed estimate, check IRCC’s current processing-time information when you apply. An immigration lawyer can also help you understand what to expect in your particular circumstances, but no lawyer can guarantee a particular processing time.

One Important Distinction: Citizenship vs. Proof of Citizenship

It is also important to understand the difference between citizenship itself and the citizenship certificate you apply for.

For someone who has acquired Canadian citizenship by descent, the citizenship certificate is generally evidence of that citizenship; applying for the certificate is not ordinarily what creates the citizenship. In other words, a person can acquire Canadian citizenship by operation of the Citizenship Act even before obtaining the certificate that proves it. The certificate generally documents and proves citizenship that already exists under the law.

That distinction matters because many families assume that they are “applying for citizenship” when, in fact, they are applying for proof of citizenship. The exact process depends on the person’s circumstances. This distinction is particularly important because citizenship by descent and citizenship granted to an adopted person under Section 5.1 are different legal pathways.

You Don’t Have to Piece This Together Alone

If you are staring at old boxes of report cards and lease agreements trying to figure out whether they add up to three years, that uncertainty is a normal reaction to a genuinely complicated legal test, not a sign your case is hopeless. Families sometimes discover additional documentation once they look across school, employment, residential, government and travel records, and a lot of it becomes clear only once someone experienced looks at the full picture with you.
