One of the most common misconceptions about Canada’s citizenship by descent law is that your parent had to be born in Canada, or have held a Canadian passport, for you to be a Canadian citizen yourself.
Since Bill C-3 took effect on December 15, 2025, that’s no longer the full picture.
The bill removed the first-generation limit on citizenship by descent for people born before that date.
That means that anyone who has a Canadian ancestor and can trace an unbroken chain of descent to them, generation by generation, is already a Canadian citizen. They just need to collect the documentation that proves it, and apply for a Canadian citizenship certificate.

Did my parent have to be a Canadian citizen for me to be one by descent?
The short answer is yes. Your parent needs to have been a Canadian citizen at the time of your birth for you to qualify for Canadian citizenship by descent. How that rule applies can depend on retroactive amendments and the citizenship law in force at relevant dates.
The important part people miss is that your parent didn’t need to think about their citizenship status, act on it or even know about it.
Canadian citizenship by descent is conferred automatically at birth. It doesn’t require an application, a passport, or any awareness on the part of the person who holds it.
That means your parent could be a Canadian citizen, and not even know it, if they had a Canadian ancestor themselves or acquired citizenship by some other means.
Here are two examples of how that plays out.
Example 1: A straightforward case
Let’s take the case of fictional Michael Stuart was born to an American family in Vancouver in 1961.
His family moved back to California six months later, and he never went back. He never thought of himself as a Canadian citizen, never held a Canadian passport, never renewed any paperwork there, and had no family or ties to Canada.
None of that matters. Michael was a Canadian citizen from the moment he was born, under Canada’s birthright citizenship rules.
Therefore, his daughter Abigail, also born in the California, is a first-generation Canadian by descent. Her case is simple: she can apply for proof of Canadian citizenship using her father’s birth certificate and her own long-form birth certificate, connecting them.
Once she gets a Canadian citizenship certificate, she can apply for a Canadian passport, despite her father never having one.
Example 2: A case Bill C-3 unlocked
Another fictional example, Marguerite Bouchard was born in Quebec and spoke French growing up. She moved to the U.S. as a young woman, married, and had a son, Robert, in Ohio. Robert grew up American. He never really thought about his mother’s Canadian background, and he never applied for a Canadian passport.
Robert had a daughter, Claire, also born in the U.S. before December 15, 2025.
Under the former first-generation limit, someone in Claire’s circumstances would not have been recognized as a Canadian citizen by descent. Now, because that limit no longer applies to people born before the cutoff date, Claire is a Canadian citizen and is able to apply for a citizenship certificate (and from there, a Canadian passport).
This is despite Robert not being born in Canada, ever having visited, and never having held a Canadian passport.
What happens if my Canadian parent never applied for citizenship or a passport?
Nothing changes about your eligibility. You’ll need to prove your parent was a Canadian citizen at the time of your birth, even if they never knew it or acted on it themselves.
In practice, that means tracing the chain back to your earliest known Canadian ancestor and documenting every link in between. If your grandparent was born in Canada, for example, you’d typically need their birth certificate, plus your own parent’s long-form birth certificate, which names your grandparent and connects the two generations.
What happens if my Canadian parent has passed away?
A death in the line doesn’t change your eligibility. Citizenship is determined by their citizenship at the time you were born, not their status today.
So even if your parent never held a Canadian citizenship certificate or passport while they were alive, you may still be able to get one yourself. You’ll need the same kind of paper trail as anyone else: documents connecting your parent to their Canadian ancestor, and documents connecting you to your parent.
Where to start
If you think you have a Canadian ancestor, start by speaking to older relatives about what they remember.
It could be something as simple as having lived in Canada years ago, speaking French, or having a surname that is famously associated with French-Canadians.
That can point you to the right ancestor and the documents you need to collect for a successful proof of citizenship application. For example, a grandparent or great-grandparent‘s long-form birth certificate in Canada, as a starting point, and then a parent’s long-form birth certificate connecting them to the grandparent.
If you are unsure if you qualify, CanadaVisa has a citizenship by descent eligibility checker which can help you do an initial check. For cases involving multiple generations, name changes, or a deceased ancestor, it’s worth speaking with a citizenship lawyer before applying.
