BILL C-3 AND CITIZENSHIP BY DESCENT: WHO QUALIFIES AND WHAT YOU NEED TO APPLY
Since Bill C-3 came into force on December 15, 2025, Immigration, Refugees and Citizenship Canada (IRCC) has seen a sharp rise in applications for proof of Canadian citizenship from people who never knew — or only recently learned — that they already qualify. The law rewrote a rule that had shut an entire generation out of Canadian citizenship, and its effects reach much further back in a family tree than most people assume. If you have a Canadian-born parent, grandparent, or more distant ancestor, it's worth understanding exactly where you stand.
What Bill C-3 Actually Changed
Before this law, Canada's Citizenship Act limited citizenship by descent to a single generation: a Canadian citizen born or naturalized in Canada could pass citizenship to a child born abroad, but that child could not pass it on to their own children born outside Canada. This "first-generation limit" had been in place since 2009, and it cut off citizenship for a large number of people with a genuine, documented Canadian lineage.
Bill C-3 removed that limit. The Ontario Superior Court of Justice had found the old rule violated equality and mobility rights under the Charter, and the new law responded by allowing citizenship to pass through multiple generations born abroad, provided the connection back to Canada can be documented.
Who Qualifies
If you were born before December 15, 2025
This is the group Bill C-3 affects most directly. If you can trace an unbroken line of descent back to a Canadian citizen — whether that's a parent, grandparent, or more distant ancestor who was born in Canada or naturalized before you were born — you are likely already a Canadian citizen by operation of law, regardless of how many generations separate you from that ancestor. There is no deadline to apply for proof of this, since the law recognizes it retroactively.
If you were born on or after December 15, 2025
A different rule applies going forward. If your Canadian parent was themselves born or adopted outside Canada (meaning you'd be second-generation or later), your parent must demonstrate a "substantial connection" to Canada for you to inherit citizenship: specifically, at least 1,095 days (three years) of physical presence in Canada before your birth. If your Canadian parent was born in Canada or naturalized here, this requirement doesn't apply to you — you qualify as a first-generation child born abroad, as has always been the case.
Lost Canadians and adopted children
Bill C-3 also extends to people historically known as "Lost Canadians" — individuals who should have been recognized as citizens under earlier, more restrictive versions of the law but were excluded on technicalities — along with their descendants. People adopted abroad before December 15, 2025 by a Canadian parent who was themselves born or adopted abroad can also now apply for citizenship for that adopted child, closing a gap that previously treated adopted and biological children differently.
Becoming a citizen “by operation of law” isn't the same as having proof: If you qualify under Bill C-3, you are legally a Canadian citizen the moment the law recognizes your lineage — but you still need to apply for a citizenship certificate to actually use that status: to get a Canadian passport, register for provincial healthcare, or access most other rights tied to citizenship. Without the certificate, you technically have the right to enter Canada, but little else is practically accessible.
What You Need to Apply
Proof of citizenship applications use a single form: CIT 0001, Application for a Citizenship Certificate. This is distinct from CIT 0002, the application permanent residents file to become citizens through naturalization — CIT 0001 involves no citizenship test and no oath, because you're not becoming a citizen through this process, you're proving you already are one.
Government filing fee: $75 CAD per application
Your own long-form birth certificate
Proof of your Canadian ancestor's citizenship — a Canadian birth certificate, a citizenship or naturalization certificate, or a Canadian passport
For each additional generation in the chain, birth and marriage records linking one generation to the next
If you were born on or after December 15, 2025 in the second or later generation: documentary evidence of your parent's 1,095 days of physical presence in Canada, such as tax records, school records, or employment records
Two passport-style photos and a photocopy of government-issued ID
Most straightforward, single-generation cases can often be filed online, but IRCC generally directs more complex applications — multi-generation chains, adopted children, or Lost Canadian cases — toward the paper application, since these require closer document review.
How Long It Takes
Processing times for proof of citizenship applications have been climbing steadily through 2026 as application volume has surged. IRCC's own posted estimate moved from roughly 12 months in the spring to around 19 months by late July, and some applicants have reported waits stretching well beyond that depending on case complexity. If you need proof of citizenship urgently — for a job, to avoid a hardship, or another pressing reason — you may be able to request expedited processing, though this is granted only in limited circumstances.
A word of caution: IRCC has begun reviewing some already-issued Bill C-3 certificates more closely. In June 2026, the department contacted a number of self-represented applicants who had recently received citizenship-by-descent certificates, asking them to return the documents pending a file review. The most common reason applications run into trouble isn't eligibility — it's documentation. A weak or incomplete evidentiary chain can restart your processing clock entirely.
Why Families Are Applying Even Without Immediate Plans to Move
Not everyone applying intends to relocate to Canada right away. For many families, securing a citizenship certificate for a child or grandchild is about keeping a door open: Canadian citizenship carries the right to work in Canada without a work permit, access to domestic tuition rates at Canadian universities, and a passport that currently ranks well ahead of several others for visa-free travel. For families with the option available to them, establishing proof of citizenship now — while the documentation trail is easier to assemble — is often simpler than trying to reconstruct it decades later.
Think You or a Family Member Might Qualify?
Do you have a Canadian parent, grandparent, or great-grandparent, and you're not sure whether Bill C-3 makes you a citizen? Eligibility under this law is often straightforward in principle but genuinely difficult to document correctly — and a weak application can mean losing a year or more to delays and re-review.
