Since Canada eliminated its generational limit to inheriting citizenship by descent last December, millions of Americans with Canadian ancestry can apply for proof of Canadian citizenship, with which they can obtain a Canadian passport.
And this spring, thousands of Americans have been applying, pushing up processing times dramatically.
If you’re not sure whether you have the Canadian ancestry needed to qualify, here are six online research tools you can try for expanding your family tree.
If you find you descend from even a single Canadian ancestor, no matter how far removed, then you qualify for Canadian citizenship by descent, provided you were born before December 15, 2025.

Family tree and discovery platforms
The following platforms can help you expand your family tree backward to search for Canadian ancestors.
Free services
| Tool | Best for | Notes |
|---|---|---|
| FamilySearch | Starting point for building a family tree and searching historical records. | - Its shared tree and user-submitted genealogies should be treated as a starting point to be confirmed by additional research, not as definitive proof. - Not all records are indexed, and some some records may be restricted. |
| WikiTree | - Free collaborative tree for checking existing research and connecting with other genealogists. - Best used for sourced profiles, hypotheses, and cousin collaboration. | - Unlike Family Search, does not contain links to historical documents. - You'll need to validate the genealogical info by cross-referencing supporting documents. |

Tracking and documenting your research
The above tools can help you with building your family tree, searching historical records, and identifying ancestors you may not have known about.
Some can also surface census entries, parish records, immigration logs, or user-submitted family trees that may point to a Canadian connection.
Be sure to keep organized documentation of your findings as your conduct the research in building out your family tree.
Several of the platforms listed above have built-in tools for documenting your findings. FamilySearch, Ancestry, MyHeritage, and Geneanet all allow you to build and save a family tree directly on the platform, attach source records, and note relationships between ancestors. WikiTree’s collaborative profiles also include source citation fields.
For researchers using general purpose software, a spreadsheet can serve for maintaining a master list of ancestors with key fields, in addition to keeping track of discrepancies between sources and information which needs to be sought out and/or validated.
For each ancestor, aim to document as much identifying information as you can. Parent-child and spouse relationships are the core of any citizenship by descent claim, but other details, such as place of birth, dates, and alternate name spellings, are often needed to confirm that a record belongs to the right person.
Once you’ve found a Canadian ancestor from whom you descend, you’ve confirmed that you’re eligible for citizenship by descent, provided you were born before December 15, 2025.
But even if you find the ancestry needed, you should not expect to walk away from the above tools with everything you need to submit a proof of citizenship application.
Finding a Canadian ancestor is only the first step.
To actually apply for a proof of Canadian citizenship certificate, you’ll require compliant copies of accepted official documents, such as birth certificates and marriage certificates, which prove a line of descent from a Canadian ancestor.
