Frequently Asked Questions

Almost certainly, yes. Bill C-3 took effect on December 15, 2025 and abolished the generational cutoff that previously blocked distant descendants. As long as your great-grandparent was born in Canada and no adoption interrupts the family line, you are considered a Canadian citizen from birth. Applying for a citizenship certificate (form CIT0001) gives you official documentation of that status.

There is no generational limit. Community members have had citizenship certificates issued tracing ancestry back to the 1730s — nine or ten generations removed. Fourth- and fifth-generation approvals are now commonplace. A first-generation limit (FGL) did exist prior to Bill C-3, but it was repealed when the law came into force in December 2025.

No. Your ancestor had no obligation to apply for a certificate, or even to be aware they held Canadian citizenship. Under Bill C-3, their descendants are deemed citizens from birth regardless of whether anyone in the line ever sought official proof. The chain remains intact even if an ancestor passed away before ever filing an application.

No. Swearing a US oath of naturalization does not strip someone of Canadian citizenship. For a renunciation to be recognized by Canada, it must be done directly with Canadian authorities, submitted in writing, and made by an adult. Simply becoming a citizen of another country is not enough to sever the chain.

Not if you were born before December 15, 2025 — there is no residency requirement, and you need never have set foot in the country. For people born on or after that date, however, the Canadian parent through whom citizenship flows must have been physically present in Canada for at least 1,095 days before the child was born (the "substantial presence test"). That rule does not apply if the child was born in Canada.

The substantial presence test only affects children born outside Canada on or after December 15, 2025. To pass citizenship to such a child, the Canadian parent must have accumulated at least 1,095 days (roughly three years) of physical presence in Canada before the child's birth date. Those days can be spread across any period — they do not need to be consecutive. The test does not apply at all if the child was born inside Canada.

No. Citizenship by descent follows bloodlines, not marriage. Your spouse cannot inherit your citizenship status. That said, once you hold a citizenship certificate you may be able to sponsor your spouse for Canadian permanent residency. After meeting the residency requirements as a permanent resident, your spouse could then pursue citizenship through the standard naturalization process.

It depends on where in the line the adoption occurred. If you were adopted but have a biological Canadian connection, you can still claim through your biological lineage — you will need your pre-adoption birth certificate to establish that link. If an ancestor somewhere in your chain was adopted, the descent through that ancestor may be interrupted unless they obtained a Canadian citizenship grant before the next generation was born.

No. Because you are already a citizen and the application is simply for proof of that status, IRCC does not require a background check, medical screening, citizenship test, or swearing-in ceremony. The review focuses on confirming your identity and verifying your lineage documentation.

Plenty of applicants complete the process independently using IRCC's official guide and community support. One thing to keep in mind: many immigration lawyers have limited experience with citizenship by descent and may be unfamiliar with Bill C-3 specifically. If you do decide to get professional help, prioritize someone who has handled C-3 cases and offers a flat-fee arrangement.

Yes. Denials issued before the Bjorkquist Decision in December 2023 were based on the first-generation limit that no longer exists. Those rulings do not reflect current law under Bill C-3, so you are free to submit a new application.

No, not automatically. Canada's tax system is based on residency and domestic income, not citizenship. If you reside outside Canada and have no Canadian-source income, receiving a citizenship certificate creates no tax obligation on its own.

Based on community experience as of April 2026, an Acknowledgement of Receipt (AOR) typically arrives around 40 days after the application is delivered. From AOR to a final decision is currently running around 10–12 months for straightforward cases — cases forwarded to the Program Support Unit (PSU) can take considerably longer. Once approved, an electronic certificate generally lands in your inbox within 48 hours.

Gen 0 (G0) refers to the earliest Canadian-born or naturalized ancestor in your family line — the person who anchors your citizenship claim. Every generation between Gen 0 and yourself must be documented for IRCC. A Gen 0 ancestor is someone who was born in Canada, naturalized as a Canadian citizen, naturalized as a British subject while residing in Canada before 1947, or was "ordinarily resident" in Canada on January 1, 1947.

CIT0001 is the primary paper application form used to obtain a Canadian citizenship certificate. It captures information about your parents and grandparents. If your qualifying Canadian ancestor is a great-grandparent or further removed, you will need to attach supplementary sheets tracing your complete line of descent. The form is submitted alongside CIT0014 (the document checklist) and your supporting records.

Yes. Family members who share the same Canadian ancestor can submit applications together or independently — no one has to wait for another person's certificate to be granted first. Pending applications elsewhere in the family line do not interrupt or invalidate the chain for other applicants.
