Five U.S. States Lead In Canadian Citizenship Eligibility

Millions of Americans may now have a stronger claim to Canadian citizenship after Canada changed its citizenship law in December 2025.

The update is especially important for people in New England, where many families have long-standing ties to Canada, particularly Quebec. In states such as New Hampshire, Vermont, Maine, Rhode Island and Massachusetts, Canadian ancestry is more common than in most other parts of the United States.

Law Change Expands Citizenship By Descent

On December 15, 2025, Canada removed the first-generation limit for citizenship by descent. This means some people with a Canadian ancestor may now be eligible to apply for proof of Canadian citizenship, even if they were born outside Canada.

Once a person receives a proof of citizenship certificate, they can apply for a Canadian passport.

The change could affect millions of Americans, especially those whose families came from Canada generations ago. Many may not even know they have Canadian roots.

New England’s Deep Canadian Connection

Much of this history comes from the movement of nearly one million French Canadians from Quebec to the Northeastern United States between 1840 and 1930. This migration is often called the “Great Hemorrhage.”

Many French Canadians crossed into nearby states for work, especially in textile mills and industrial towns. Over time, their descendants became part of local communities while still carrying Canadian family lines.

According to 2024 U.S. Census Bureau data based on self-reported Canadian ancestry, New Hampshire ranks first at 8.06 per cent. Vermont follows at 7.59 per cent, Maine at 7.00 per cent, Rhode Island at 4.05 per cent and Massachusetts at 3.40 per cent.

Experts suggest the real number may be much higher because many Americans do not know their full family background.

New Hampshire, Vermont And Maine Lead The List

New Hampshire may have one of the strongest links. The article notes that nearly one in three residents could potentially qualify as dual Canadian-U.S. citizens. Manchester became a major centre for French-Canadian workers, with about 23,000 French Canadians living there by 1910.

Vermont also has deep French-Canadian roots. Ed McGuire, former president of the Vermont Genealogy Library, has estimated that around 30 per cent of Vermont residents may have French-Canadian ancestry.

Maine shares a long border with Quebec and was another major destination. Lewiston became especially known for its Franco-American community. By 1920, Franco-Americans made up nearly half of Lewiston’s population, and one neighbourhood is still remembered as “Little Canada.”

Rhode Island And Massachusetts Also Stand Out

Rhode Island ranks fourth by self-reported Canadian ancestry. Woonsocket, in northern Rhode Island, had a large French-Canadian population by 1900 and is still known for its strong French-American heritage.

Massachusetts also played a major role in French-Canadian migration. By 1990, it had the largest Franco-American population in the United States, according to the New England Historical Society.

Some family names may offer clues. French names, or names changed into English over time, can help people begin tracing their ancestry.

Proof Still Requires Documents

People who believe they qualify must apply for proof of Canadian citizenship before seeking a passport. This process requires official records, including birth, marriage and death certificates, connecting each generation back to a Canadian-born ancestor.

As of the article’s publication, proof of citizenship applications were taking about one year. A Canadian passport application usually takes another 10 to 20 business days after the certificate is received.

Many Americans are applying not because they plan to move immediately, but because they want a Canadian passport as a backup option during uncertain times.
