Many Americans may already qualify for Canadian citizenship without moving to Canada. Changes made to Canada’s Citizenship Act in December 2025 have expanded citizenship by descent, allowing more people to claim Canadian citizenship through their family history.
For many eligible Americans, this option is much faster than immigrating to Canada through permanent residence. Instead of spending years meeting residency rules, language requirements, & citizenship tests, qualified applicants may simply need to apply for proof of Canadian citizenship.
This pathway has become especially important for Americans who have Canadian parents, grandparents, or earlier Canadian ancestors. In many cases, they may already be Canadian citizens under the law and only need official proof of their status.
What Is The Citizenship By Descent Route?
Americans generally have two ways to become Canadian citizens while keeping their U.S. citizenship. One option is to immigrate to Canada, become a permanent resident, and later apply for citizenship. The second option is citizenship by descent, which allows eligible people to inherit Canadian citizenship through their family line.
The difference between these two pathways is significant.
| Citizenship By Descent | Naturalization | |
| What you need to start | One Canadian ancestor, plus documents for each generation | Canadian permanent residence |
| Must you move to Canada? | No | Yes |
| Physical presence in Canada | None | 1,095 days (~three years) within the previous five years |
| Language test | No | Yes |
| Citizenship exam | No | Yes |
| Oath ceremony | No | Yes |
| Current processing time | 19 months | 6-12 months, after the years above |
For people applying through naturalization, becoming a permanent resident is the first major step. Depending on the immigration program, obtaining permanent residence itself may take several years.
Only after receiving permanent resident status and meeting the required physical presence in Canada can someone apply for citizenship.
On the other hand, citizenship by descent is very different. Eligible applicants can apply immediately for proof of citizenship. There is no requirement to move to Canada or spend time living there before applying.
Does The New Law Apply To Americans?
For many years, Canadian citizenship by descent was limited to only the first generation born outside Canada. This rule, known as the first-generation limit, was introduced in 2009.
Everything changed after the Ontario Superior Court of Justice ruled in December 2023 that this limit was unconstitutional. Parliament later passed Bill C-3, which came into effect on December 15, 2025, removing this restriction for many families.
As a result, many more Americans may now qualify for Canadian citizenship through their family history.
Under the updated law, individuals born before December 15, 2025, who have a direct line of descent from a Canadian citizen may already be Canadian citizens, even if several generations separate them from their Canadian ancestor.
In these situations, applicants are not asking Canada to grant citizenship. Instead, they apply for a proof of Canadian citizenship certificate, which confirms the citizenship they already have under Canadian law.
There is also another way someone can automatically become a Canadian citizen: birth in Canada. Most people born on Canadian soil receive Canadian citizenship at birth, although there are limited exceptions, such as children born to foreign diplomats.
How Can Americans Find Canadian Family Connections?
Many Americans are surprised to discover that their family history includes Canadian ancestors.
Large numbers of Canadians moved to the United States during the nineteenth and early twentieth centuries. Because of these migration patterns, many American families today have Canadian roots without realizing it.
One helpful starting point is looking at where earlier generations of the family settled.
Many Canadians moved to New England, especially from the Maritime provinces. Others settled in Michigan, Minnesota, Wisconsin, Montana, and the Dakotas. French-speaking Canadians from Quebec also moved in large numbers to textile towns across New England.
These communities included places such as:
- Lewiston
- Manchester
- Lowell
- Fall River
- Woonsocket
Over time, many descendants became fully established in the United States, and family stories about their Canadian origins gradually disappeared.
There are several clues that may suggest Canadian ancestry.
Family Location
Families living in parts of New England often have stronger historical connections to Canada. Some experts believe that many residents in this region may qualify for Canadian citizenship by descent because of earlier migration.
States such as Michigan, Minnesota, Wisconsin, and Louisiana also have strong historical links to Canada.
Family Surnames
Certain surnames may also point toward Canadian ancestry.
Names such as:
- Tremblay
- Ouellet
- Roy
- Desjardins
are commonly connected to French-Canadian families.
In other cases, original French surnames were translated or changed after families settled in the United States.
Examples include:
- White
- King
- Wood
- Greenwood
Although a surname alone cannot prove eligibility, it can provide an important clue during family research.
Family Stories
Old family memories may also help uncover Canadian roots.
Stories about relatives in Ontario, Nova Scotia, or other Canadian provinces may provide valuable leads. Some families also remember annual trips ‘up north’ or relatives who continued living in Canada after others moved to the United States.
In French-American families, references to grandparents using names like Mémère and Pépère may also point toward Canadian heritage.
As applicants continue researching earlier generations, they often discover additional records that help build the family line needed for a citizenship by descent application.
What Changes After Receiving Canadian Citizenship?
Canada and the United States both allow dual citizenship. This means eligible Americans can legally hold both Canadian and U.S. citizenship at the same time.
Having Canadian citizenship gives people access to many rights and benefits without giving up their American citizenship.
One common concern is taxes.
Simply becoming a Canadian citizen does not automatically create Canadian tax obligations. Canada generally taxes people based on where they live rather than their citizenship. Therefore, someone who continues living in the United States usually keeps filing taxes there and does not automatically need to file taxes in Canada.
However, the situation changes if a person later moves to Canada.
The United States taxes its citizens on worldwide income, even if they live in another country. Canadians who are also U.S. citizens may therefore need to file tax returns in both countries. Fortunately, the Canada-U.S. Tax Treaty and foreign tax credits help prevent most people from paying tax twice on the same income.
What Rights Does Canadian Citizenship Provide?
Receiving proof of Canadian citizenship gives eligible individuals the same rights as other Canadian citizens.
Some of the main benefits include:
- The right to live anywhere in Canada.
- The right to work in Canada without needing a work permit.
- The freedom to change employers without immigration restrictions.
- The ability to study in Canada as a Canadian citizen.
- Access to provincial health care after meeting provincial residency requirements.
- Protection from being removed from Canada through deportation.
- The right to enter Canada as a Canadian citizen.
Unlike temporary residents or permanent residents, Canadian citizens cannot be refused entry into Canada if they meet normal travel requirements.
These rights make citizenship by descent especially valuable for people who may wish to move to Canada in the future, even if they have no immediate plans to relocate.
Can New Citizens Apply For A Canadian Passport?
Yes.
Once proof of Canadian citizenship has been approved, eligible individuals can apply for a Canadian passport.
A Canadian passport is one of the world’s strongest travel documents and allows visa-free or easier travel to many countries.
Dual Canadian-American citizens can travel using either passport when entering Canada. However, carrying both passports often makes international travel smoother and helps avoid questions during airline check-in and border inspections.
Can Canadian Citizenship Be Passed To Children?
The rules for passing citizenship to children depend on when the child was born.
Children born before December 15, 2025, generally inherit Canadian citizenship if their parent qualifies under the updated citizenship by descent rules.
For children born on or after December 15, 2025, a new requirement applies under Bill C-3.
In most cases, the Canadian parent must have been physically present in Canada for at least 1,095 days (three years) before the child’s birth or adoption to pass Canadian citizenship through descent.
This rule affects future generations, so families planning ahead should understand how the updated law works.
Why Is This Path Becoming More Popular?
The changes introduced through Bill C-3 have opened the door for many Americans whose families left Canada generations ago.
Instead of spending years qualifying for permanent residence and later applying for citizenship, eligible applicants may already have Canadian citizenship through their family line.
For those who qualify, citizenship by descent removes many of the usual immigration requirements.
Applicants do not need to:
- Move to Canada before applying.
- Meet physical presence requirements.
- Pass a language test.
- Take the Canadian citizenship test.
- Attend a citizenship ceremony.
Instead, the focus is on proving an unbroken family connection to a Canadian citizen using official government records.
