The top five states where Americans qualify…

Nearly one in three New Hampshire residents may now qualify for dual Canadian-U.S. citizenship following Canada's elimination of the first-generation limit on citizenship by descent in December 2025. The change, which took effect December 15, 2025, makes millions of Americans with even one Canadian ancestor eligible to apply for proof of Canadian citizenship certificates and obtain Canadian passports.

The shift reverses a decades-old restriction that had capped inherited citizenship at the first generation born outside Canada. Before December 2025, only children of Canadian citizens born abroad could claim citizenship by descent; grandchildren and further generations were excluded. The new rule extends eligibility indefinitely through the family line, provided applicants can document the ancestral connection.

New Hampshire leads U.S. states in Canadian ancestry, with 8.06% of residents reporting Canadian-born roots in 2024 U.S. Census Bureau data. Vermont follows at 7.59%, Maine at 7.00%, Rhode Island at 4.05%, and Massachusetts at 3.40%. These figures reflect self-reported ancestry; genealogists estimate the actual number of Americans with Canadian roots in New England is three to four times higher, as many remain unaware of their heritage. The concentration stems from the "Great Hemorrhage," a mass migration of nearly one million French Canadians from Quebec to the Northeastern United States between 1840 and 1930. By 1910, approximately 23,000 French Canadians lived in Manchester, New Hampshire, alone, comprising 38% of the city's population and dominating the textile mills. In Vermont, more than 16,000 French Canadians had settled by 1860, double the number in any other New England state. By 1920, Franco-Americans represented nearly half of Lewiston, Maine's population, and by 1900, French Canadians comprised 60% of Woonsocket, Rhode Island.

"Around 30 percent of Vermont residents have French-Canadian ancestry," according to Ed McGuire, former president of the Vermont Genealogy Library, as reported by CIC News.

The policy change primarily affects descendants of French-Canadian migrants in New England, though Americans with Canadian ancestry from any province or era may qualify. Applicants must trace their lineage to a Canadian citizen ancestor and provide documentation such as birth certificates, marriage records, and proof of the ancestor's Canadian citizenship. The pathway applies regardless of how many generations separate the applicant from the Canadian-born relative, provided the chain of descent is unbroken.

Americans seeking to confirm eligibility should gather family records documenting the Canadian ancestor's birth or naturalization in Canada, along with birth and marriage certificates linking each generation. Applications for proof of citizenship are filed through Immigration, Refugees and Citizenship Canada, and processing times vary depending on the complexity of the genealogical evidence required.
