Canada’s December 2025 citizenship law change may make many Americans with Canadian ancestry eligible for Canadian citizenship by descent, especially in New England states with historic French-Canadian migration from Quebec.
On December 15, 2025, Canada eliminated the first-generation limit for inheriting Canadian citizenship by descent. The change means Americans with a qualifying Canadian ancestor may be able to apply for proof of Canadian citizenship and then use that certificate to obtain a Canadian passport.
The strongest concentration of potential eligibility is in New England, where large numbers of French Canadians migrated from Quebec to the Northeastern United States between 1840 and 1930. That migration is often referred to as the “Great Hemorrhage.”
The estimates below are based on 2024 U.S. Census Bureau data on self-reported Canadian ancestry. The actual number of people with Canadian ancestry in New England may be three or four times higher, because many residents may not know they have Canadian roots.
New Hampshire
New Hampshire ranks first among U.S. states for self-reported Canadian ancestry, with 8.06% of residents reporting Canadian ancestry in 2024.
The state’s connection to Canada largely comes from French Canadians who migrated from Quebec between 1840 and 1930. Many settled in industrial towns such as Manchester, where textile mills created strong demand for labor.
By 1910, around 23,000 French Canadians were living in Manchester alone, making up 38% of the city’s population, according to genealogist Kim Kujawski.
The article estimates that nearly one in three New Hampshire residents may qualify as dual Canadian-U.S. citizens under the updated citizenship rules.
Vermont
Vermont has one of the strongest French-Canadian ancestry profiles in the United States, helped by its shared border with Quebec.
Around 30% of Vermont residents are estimated to have French-Canadian ancestry, according to Ed McGuire, former president of the Vermont Genealogy Library. That suggests roughly one in three Vermonters may now have a claim to Canadian citizenship.
By 1860, more than 16,000 French Canadians were estimated to have settled in Vermont, more than double the number in any other New England state at the time.
According to 2024 U.S. Census Bureau data, 7.59% of Vermont residents self-reported Canadian ancestry.
Maine
Maine shares a long land border with Quebec and was one of the most accessible U.S. destinations for French Canadians during the Great Hemorrhage.
Lewiston was a major destination. By 1920, Franco-Americans represented nearly half of Lewiston’s population, according to the Maine Museum of Innovation, Learning and Labor.
Lewiston still has a neighborhood remembered as “Little Canada.” Around 7% of the city’s current population reports Canadian ancestry, placing it third among American cities with Canadian roots.
Rhode Island
Around one in seven Rhode Islanders is estimated to qualify for Canadian citizenship after the change in Canada’s citizenship law.
Woonsocket, in northern Rhode Island, has especially strong French-Canadian roots. By 1900, French Canadians made up 60% of the city’s population. The city is still referred to as la ville la plus française aux États-Unis, meaning the most French city in the United States.
Rhode Island ranks fourth among U.S. states for self-reported Canadian ancestry, with 4.05% of residents reporting Canadian ancestry.
For genealogy research, the American-French Genealogical Society in Woonsocket holds more than 20,000 volumes of vital statistics and historical records focused on French-Canadian descent.
Massachusetts
Massachusetts was one of the largest destinations for French Canadian migrants during the Great Hemorrhage.
Estimates cited in the article suggest that as much as 10% of Massachusetts residents may have Canadian ancestry. According to the New England Historical Society, Massachusetts had the highest number of Franco-Americans in the United States by 1990, with 310,636 people, nearly half of all Franco-Americans in New England.
Based on self-reported U.S. Census Bureau data, 3.4% of Massachusetts residents reported Canadian ancestry.
Because many of the migrants were French Canadians, surnames can be a clue. French-sounding names or anglicized names may indicate possible Canadian ancestry. Examples include Charpentier becoming Carpenter and Leblanc becoming White.
How Americans Can Claim Canadian Citizenship by Descent
Americans who can trace a continuous line of descent from a Canadian ancestor may already be Canadian citizens under the new law.
To obtain a Canadian passport, they must first apply for proof of Canadian citizenship. This requires a proof of Canadian citizenship certificate.
Applicants need official documentation proving each generational link back to the Canadian-born ancestor. This can include:
- Birth certificates
- Marriage records
- Death certificates
- Other compliant official records showing the family line
Collecting compliant copies of these records is often the most labor-intensive part of the process.
Once the documents are prepared, the application is submitted to Immigration, Refugees and Citizenship Canada, known as IRCC.
At the time of writing, proof of citizenship applications take roughly one year to process. After the certificate is issued, applicants can use it to apply for a Canadian passport, which usually takes 10 to 20 business days.
Many Americans pursuing this route are not necessarily planning to move to Canada. Some are applying for a Canadian passport as a backup option during uncertain times.
