You might already be a Canadian citizen and not know it.
Thanks to a landmark law passed in December 2025, millions of Americans with Canadian roots now qualify for citizenship by descent.
Whether your grandparents left Quebec during the Great Depression or your great-grandmother crossed the border from New Brunswick, the path from ancestors to a Canadian passport is more straightforward than you might think.
Here’s your step-by-step roadmap.

A Quick Word on the New Law (Bill C-3)
Before December 15, 2025, Canadian citizenship by descent was limited to one generation born outside Canada. That meant if your Canadian-born grandparent had a child abroad (your parent), and you were also born abroad, you were cut off, even if your family’s Canadian roots ran deep.
Bill C-3, An Act to amend the Citizenship Act, changed that. For anyone born before December 15, 2025, the generational limit has been removed entirely. If you can trace an unbroken line of citizenship back to a Canadian ancestor, grandparent, great-grandparent, or beyond, you may already be a Canadian citizen from birth.
You do not need to apply to become a citizen; you need to apply for a document that proves you already are one.
Step 1: Start Your Research (Months 1–2)
Open an account on Ancestry.com, FamilySearch.org, or both.
These are the two most powerful platforms to begin your search:
- Ancestry.com: The largest paid genealogy database in the world, with billions of digitized records. Its Canadian collections include census records from 1851–1921, passenger lists, and vital statistics from every province. Use the Canada-specific search filters and look for hints that automatically connect your family tree.
- FamilySearch.org: Completely free, operated by The Church of Jesus Christ of Latter-day Saints. FamilySearch holds millions of Canadian records, including Quebec Catholic parish registers (often the best source for French-Canadian roots), Ontario county records, and immigration documents. It’s an essential complement to Ancestry, especially for pre-1900 research.
Other Platforms Worth Exploring:
- MyHeritage: Strong global records with excellent AI-assisted photo tools; particularly useful for cross-referencing family trees.
- Findmypast: Good coverage for Maritime provinces and records with British colonial roots.
- Library and Archives Canada: The official federal archive. Search census records, land petitions, and naturalization files directly here. This is a primary source.
- FamilyTreeDNA: If documentary records are thin, DNA matching can identify Canadian cousins who may hold the documents you need.
Your goal at this stage: Identify the ancestor who is your “anchor” — the person who was a Canadian citizen in your direct family line.
Step 2: Build Your Document Chain (Months 2–4)
This is the most important step, and the one that determines whether your application succeeds.
IRCC requires an unbroken chain of official documents linking you to your Canadian ancestor, generation by generation. For each person in the chain (you → your parent → your grandparent, and so on), you’ll need:
- Long-form birth certificates (or equivalent, such as a hospital birth record, census records, or baptismal certificate)
- Marriage certificates (to connect different surnames across generations)
- Canadian citizenship or naturalization records (if your ancestor became a Canadian)
Where to Obtain Official Canadian Documents:
For ancestors born before modern civil record-keeping, IRCC accepts certified baptismal records as an alternative to birth certificates, provided the records are authenticated by the institution. Historical census records from Library and Archives Canada can also serve as corroborating evidence to establish an ancestor’s presence in Canada.
If your family’s Canadian roots are in Québec, certified parish records can be obtained from the Directeur de l’état civil (DEC) or the Bibliothèque et Archives nationales du Québec (BAnQ). Demand for these records has surged dramatically since Bill C-3 passed, so request them as early as possible.
NARA (U.S. National Archives) includes US immigration records, naturalization papers, and border crossing records that can confirm when a Canadian ancestor entered or resided in the U.S.
Documentation Note
-
Certified Copies Required
Ancestry.com printouts and screenshots are not sufficient on their own. You need certified or authenticated copies from the issuing civil authority.
-
Alternative Evidence Accepted
However, IRCC has confirmed that where a formal birth certificate is unavailable, alternative evidence, including census records, baptismal certificates, and ship manifests, may be assessed on a balance of probabilities, provided the documents are properly sourced with full metadata.
Step 3: Apply for Your Citizenship Certificate (Month 4–6)
Once your document chain is assembled, you’re ready to apply for proof of citizenship, officially called a Certificate of Canadian Citizenship.
- Complete the application forms
- Pay the fees: CAD $75
- Processing time: Currently running approximately 12–15 months due to high volume. As of mid-2026, roughly 82,000 applications are in the queue.
- Submit online through your IRCC secure account
You do not need to travel to Canada to apply.
Step 4: Apply for Your Canadian Passport
Once your certificate arrives, you can immediately apply for a Canadian passport through Passport Canada. Your citizenship certificate is your proof of status. Standard processing is 10-20 business days.
Dual citizenship is fully permitted, and the U.S. explicitly allows its citizens to hold foreign passports, so there is no requirement to give up your American citizenship.
A Note on Recent Certificate Reviews
In mid-June 2026, IRCC sent letters to a small number of certificate holders, described by the department as “a few dozen,” requesting they return their documents for further review due to documentation concerns.
The important news is that IRCC has already begun reversing those suspensions. Within a week, some recipients received confirmation from IRCC that their citizenship claims had been revalidated following a “thorough review.” The department has been responsive and supportive throughout the process.
This development underscores the key lesson for applicants: documentation quality matters. Ensure your records are certified originals or authenticated copies from official civil registries — not simply digital records pulled from genealogy websites. Include full metadata for any archival records.
If you cannot obtain a document, you explain in a letter of explanation why you cannot provide it, and provide proof that you tried to obtain it.
A well-documented application protects your certificate.
