Since Canada eliminated the generational limit on citizenship by descent last December, millions of Americans with Canadian ancestry became eligible to apply for proof of Canadian citizenship and obtain a Canadian passport. Thousands of applications have flooded in this spring, driving processing times sharply upward.

Under the previous rules, citizenship by descent was capped at the first generation born outside Canada. Now, anyone born before December 15, 2025, who descends from even a single Canadian ancestor—no matter how many generations removed—qualifies for citizenship by descent. The change represents the most significant expansion of Canadian citizenship eligibility in decades.

Applicants must trace their lineage and document the connection to a Canadian-born ancestor. Six online genealogy platforms are proving especially useful for Americans searching their family trees, as reported by CIC News. FamilySearch offers a free starting point for building a family tree and searching historical records, though its shared tree and user-submitted genealogies require confirmation through additional research. WikiTree provides a free collaborative tree for checking existing research and connecting with other genealogists, but does not contain links to historical documents—users must validate genealogical information by cross-referencing supporting documents.

Among freemium services, Geneanet specializes in French, European, Acadian, and French-Canadian ancestry leads, with a free account for tree building and a premium subscription available at $4.55 USD for advanced features. Ancestry offers a 14-day free trial and paid plans ranging from approximately $25 to $60 per month; the platform contains U.S.-Canada links, including Canadian census collections and the Drouin Collection. "The lowest tier paid plan is U.S. Discovery, so a higher-tier plan such as World Explorer may be more appropriate for users seeking Canadian ancestors," the article notes.
